Sorted by range
Hybrid – Standard def. composite only.
Color is stable and decent enough for experienced DIT to do painting with on the set. Available worldwide. Has only composite IN/OUT but is digital over the air so it’s a rock solid picture always. Small handheld Rx with 7” screen is nice for directors on board batt good for 3hours. Always has good continuous sync output, even when Tx is out of range – will not crash computer recorded files. Rock-solid, field hardened and tested mature system. 9-30V. Will penetrate 5 sheetrock houses, 4 downtown blocks line of sight. 2 versions: No audio and with audio. 30-mile version available, 8 can be used simulteaneously in same space.
Lock up: from cold: 10 sec, out of range 2 sec.
Delay: 2 frames, 50 msec just manageable for remote heads with a CRT monitor
Range: 2 miles outside LOS (yes!!)
Price TX-RX: $ 6.8 K with antennas, rental available worldwide $ 500/day.
Slick 7” Handheld available Price: $ 5K, rental $ 300/day

Micro Lite HD by RF central
5.8G Picture quality: pretty darn good, good enough for a DIT to make color decisions. HD/SD or composite input, HDSDI output in same format as input!! and composite out (Mfct says). Now available in the March 2012. Tx size: less than a cigarette pack plus 6” stiff antenna (fragile) small fan that can be disabled for they say 8 min. Awkward channel change for 2 camera use on one receiver. 16 presets have to be cycled thru by repeatedly pressing the set button to get from channel 2 to1. Seems to be better thru walls than Boxx. Good to go thru 3+ sheet rock houses. Receive stick antennas have a front and a rear and need to be oriented for best range like the panels. Expensive custom antennas. If Tx is on a 5D it takes a 12 sec preroll for pix to be stable at RX. No genlock avail. Sync continues when pix lost. 9-28V. FCC ID: 14U-58MLT
Lock up: from cold: 30 sec, out of range 4 sec.
Delay: 3-frame delay at 24. 120 ms, too much delay for most hot head operators
Range: 500 yards LOS.
Price TX-RX: $ 21.5 K with antennas. Rental $ 750/day.

CATV analog over the air Europe and Canada low price solution:
Transmitters (cost under $ 200) for SD with NO delay can be received by any cheap TV tuner. These frequencies are used in Europe and Canada, and this is by far the cheapest, reliable and best looking with low flicker, low price solution. Range 300 yards, yes - they occasionally flicker, color is so-so NTSC…. Available from various Chinese dealers.
Teradeck Video cube
Have several models. HDSDI in but lower quality SD out on tablets and phones maybe Android? (There are many other tablet computers than the IPhones/pads that work as receivers but look much better in sunlight) I don’t know how to record it and playback??
Price: $ 2000.00 approx
Range: said to be 50 feet to tablets, must use WiFi 5.2 G not 2.4G.
Delay: 3-10 frames depending on quality, to one tablet - much more if you have to distribute it thru a router to many WiFi based computers. First time novice set up takes at least 4 hours with tech help on phone. Router takes more time and experience and continuous maintenance.
Color drifts and changes, not good enough for DIT. Picture quality and color nowhere near as good as Camwave, Boxx. ( only used by folks who don’t know from UHF and TVs)
LOS= Line of sight, no obstructions whatsoever outside with minimal metal around (cars – yes, electrical wires - yes, High tension wires – no). Note as soon a LOS is disrupted with a human body or a thin wooden wall the range of all the high frequency HD systems is severly reduced, unless there is a metal object off to the side that reflects the signal to the Rx. Digital Tx like reflections, unlike the older analog UHF stuff.

From the video assist board on Yahoo:
http://movies.groups.yahoo.com/group/VideoAssist/message/6268
Gaylen :
I did Second Unit on Spiderman.
Noodles (RF Films) was providing the transmitters. They Used both the IMT CAMPAC'S and there own version. Neither are ZERO Latency. They are darn close at about 40ms delay. These solutions are around $40-80K It worked quite well in general. They Used AJA HI-5 3D to mux and sent a single line transmission. It was not without it's issues and Noodles had alot of issues. Some were "RED Ache's" and some related to his transmitters.. Although Red Epic will Genlock they are very sensitive to anything from physical connection problems to Voltage variation to unknown strangeness. Any loss if sync is a problem for us in 3D. Qtake can easily fix many sync glitches by re-syncing during playback but it the transmitter takes a hit it's done. There were a few takes that we had to go without the signal and watch back from the camera. 3Ality has nothing to do with video transmission.
There will be other lower cost systems for this longer range transmission in HD.
I have tested a system that worked quite well at 1500 feet with 4 frames of delay. Microlite Hd is also made by IMT but sells for $18,500 tx and rx. Directly after NAB I had two Beta transmitters that I tested for them. They have to do quite a bit of revision for Hd framerate and signal compatibility but they are getting much closer and I will update the group as soon as I have tested it again.
Boxx is the System for 0 Latency! The range is only about 500 feet. It is good enough for many applications. ( it does timecode if the signal is good. ed.)
Gaylen
Re: HD Transmitters used on Spiderman for 3D links
Gaylen, regarding the Boxx system, didn't you find it a bit big? Or did I see
the wrong system at NAB?
What were the issues you had with the MicroLite HD? I liked it, but the issues
I had were the channel selector on the Rx, in that you cannot go in reverse,
i.e. channel 3 to 2 without going through the full channel sequence. Directors
would have a fit with that on a hand-held monitor. The other thing was the :30
second diagnostic it performs every time it powers up. Not a good thing when a
sudden battery swap has to be done. We need near instant on.
-Pete
You are correct Pete. The Boxx is big. It is also the best on the Non delay systems out there.
IDX, Boxx,Transvideo, intervideo, and J Labs all use the Amimon chipset.
30 meter range, no line of sight required Less than 1 millisecond latency.
They are made to throw a picture across your living room. The question is who is best at making it go farther. So far that is the Boxx using the Full 5.2-5.8 Wi-Fi Bandwidth with spread spectrum technology. They are fully FCC approved because they detect anyone else on the frequency and automatically hop off the channel allowing them find a clear channel and to use more power legally.
The systems come in two flavors. One (15.5K) uses a 4 patch "antenna farm" . The bigger and more expensive system uses 7 patch antennas.(22K). They have recently started to take off with more and more shows turning to this solution. The steadicam ops seem to like these the best.
All wireless systems are trouble at some point!
I really cannot comment on the issues with MicroliteHD.
(not really ready yet)
Gaylen
The Boxx system was used on Pirates of the Caribbean when they were shooting
here in the UK but it had it's problems. I'm trying to gather as many systems
together as I can for some comparative tests and make the decision from there.

superficially it looks like Chinese gear with USA paint.
Jeremy Hawkins salesman for the company said in Feb 2008: We OEM'd a specific unit for Wexler that was the same as the 1450's you can get at VER, but had specific connectors, channel presets, and power settings!
The new 1550 units that you saw on the website have the same things as the Wexler, but have more channels, are digital adjust, and are fine-tunable. We are waiting for FCC on them, but we should have FCC part 15, 74, and 90 on them in "a couple of days" according to the manufacturer.
Coherent’s 900MHz analog 10 channel
ASK FOR OUR BLOW OUT PRICES ON USED ONES
Microwave FM analog system uses special diversity receivers, that means a lot less flicker. A special version can burn TC in picture. We get 1.5 miles on a golf course out of this system after we tweak it; 3 miles on a helicopter. Often problematic in the big cities as there is masses of 900 stuff around. There is no need for a 2nd guy to point receive antennae unless you are at the ragged end of range. These systems are now produced by new owners – Halcyon halcyonmicro.com or http://cocom.com/pages/pro.htm - with higher prices. We have them in rental packages as a fully legal system in the USA for any use – No license required, FCC Part 15 licensed. These systems work better than the stuff at 2.4G because of lower frequency and diversity reception. But in the big cities 900 is full of junk transmissions by data liks etc. and range will be shorted to half in most downtowns or commercial-convention areas. Rx antennas are larger than 1.2 G. perfect for Helicopter work.

2.4 G high and low power – not good for moving Tx
WSV Point to point 2.4 link
This is a 1 mile video/audio link in the USA to be used under Part 97. approx .8 watt. Works best with fixed antennae (non-moving) pointing at each other. If you use this kind of system with a moving Tx the flicker is so persistent it’s annoying to the extreme. There are versions of this for overseas use with 50 mile range. Simple to set up. No technician needed. Often this becomes part of a repeater system that looks around one corner or over one hill. Available for rent (with 2 beautiful small Helix antennae) or sale. There is a wide range of commercial antennae available for reasonable prices. 2.4 in the cities is useless now as there is so much WiFi that destroys the picture. Approx $ 200.00 for the pair Tx-Rx. Sometimes this page works:

Avalon 2.4Mhz Diversity,
1 Watt (for overseas use) with 1 mile range. http://avalonrf.com/Products/transmitters/tx500_tx600.html Very low power version available for USA with minimal range – approx 50 feet. TX600 Series comply to FCC Part 74 and Part 90. You need to put up 4 pieces of 4” square flat panel antenna 2 feet apart – nicely made, pro-connectors. www.Avalonrf.com. Not good on a stage covered with chicken wire. Occasional highlight reversal like Coherent. Coherent range is TWICE. WSV FM2 is TEN TIMES. Penetration of sheet rock not good Ouch! Not much good in cities nowadays there is so much 2.4 stuff that there is no room for this to work well in the urban areas of the wired wireless world. Factory service varies as to permanently changing ownership. Price: minimum package US $7200.00. Not really sure if these are on the shelf all the time. Avalon changed owners in 05. If they don’t have it in stock I do not know if they can deliver. Similar stuff is made cheaply and poorly in China. Someone said Avalon is not in business anymore in 2009? Better check.

Hybrid works well in NYC. we had 4 going in Times square.
For the modulus we make cut to frequency half wave antennae. $ 50 each
Better tuners than handhelds keep some of the excessive RF out of the front end and therefore are not swamped and desensitized by NYC RF garbage. The Sony 1041 is slightly better at this.. slightly.
Legal Newsflash:
There is provision in the federal regulations now to use Video Assist transmitters with some restrictions with permission in the USA. Look at: Federal Communications Commission §74.870 47 CFR Ch. I (10-1-04 Edition) They ask the manufacturer to: include with a wireless assist video device information regarding the requirement for users to obtain an FCC license, the requirement that stations must locate at least 129 kilometers away from a co-channel TV station, the limited class of users that may operate these devices, the authorized uses, the need for users to obtain a license, and the requirement that a local coordinator (or adjacent channel TV stations, if there is no local coordinator) must be notified prior to operation.

the regulator needs to be heat sink mounted to metal and needs small tantalum capacitors at in and output so the RF the regulator generates does not get into the front-end of the receiver and degenerate sensitivity.

Modulus 5000 New in summer 2009. Only a few samples floating around by Sept. (Terry West has one, there is one in Great Britain and Canada at Crevier's). Not sure what its delay is (it takes at least one frame to downconvert the HDSDI to composite for Tx).
HDSDI in SD composite out at Rx
It takes a HDSDI signal in and downconverts it then and transmits it the usual way on UHF analog just as the Modulus 3000 did – so it has all the usual UHF transmission problems: flicker, multipath etc.
Composite video input plug doubles as a composite line out for a local SD monitor when using HD-SDI/SDI input. You can receive it as UHF analog SD on any old TV as before. There is a version that is USA legal and one for Ex USA sale.
Power plug 9-36 V is different form 3000, you need new cables. Most are $ 150. Dimensions 1.7 x 4.7 x 3" (43x120x78mm) Weight 18oz (510g) To view the official propaganda from the manufacturer look here: http://wolfvid.com/datasheets/Modulus_5K_Cut_Sheet.pdf
Modulus 5000 Marked down till end of 2009 - Price $ 2000
Classic Modulus 3000 Marked down till end of 2009 - Price $ 1700

Happy to report CIT now only takes Months instead of eons to repair the Modulus they designed. 80% of the time the repair is good the first time. Billing is down to occasional weeks. Hamlet is a real nice guy and his English has really improved ( he sells his own stuff) - no answering mashine. The folks in Canada ( also selling a low powered version) are nice and have done wonders and disasters. Terry West will help in a pinch but has better things to do. We don't repair, but make cables ( most in stock) i can hook you up with some used ones- generally its a very sad state of affairs. ( boy did I just make enemies) wolf
PS the Canatrans now is very stable and needs no repairs. still 4K
the MODULUS 5000 is out. $ 1700 approx. it has a built in downconverter and a 3000 to transmit analog video as usual. THe price is right. Have no personal experience with it. ( by the way producers can get permission now to use Modulus etc. for video assist)

Red One powering Dilemma
If it offends you that this does not deal with on board Steadi batts stop reading now
The only small limited lifetime Lithium battery that gives a true state of charge indication in the viewfinder is made and sold for big bucks by RED one. The alternative NiMHd block batteries from Bauer etc are expensive and have no state of charge indication. So we will investigate the lower priced sealed Lead Acid batteries and discuss its problems.
The Red One video camera while recording on HD, draws 5.5A with no accessories; that translates into 4-Hr use on a good, new 12V 28AHr Lead Acid battery block (weight 22 pounds). It will shut off at 11.5V. This is meaningless though because the camera relies on heavy use of accessories.
The Red One with full accessories (its monitor (.7A), operating FIZ 91.5A), cam-tape, 2nd monitor for Assist, HD transmitter, etc..) draws 9.5A. That reduces lifetime down to 11.5V cut-off to an actual 1-Hr use. Some assistant monitors of course cut off at 12.1V.
What helps? 12-Ga shorter battery leads with clean connectors. 4XLR wired 1=2, 3=4. New batteries…. But that’s not enough…
Voltage display - Heavy current draw – battery capacity indication.
Get this:
Source and description: http://wolfvid.com/datasheets/Battery_watcher.pdf
If you draw 9A (like the Red One) from a 28AHr Lead Acid battery: Right off the charger, the Battery Watcher at the battery 4XLR reads 13.6V. After 2 minutes under load, it reads 12.6V - after 1 hour, it reads 11.7V and the Red One shuts down. The Red One sees only 11.5V at the end of an average 8ft 16 Ga cable. The Battery Watcher shows that only 8Ahr of the batteries’ 28AHr has been used. After 48 hours without a load, the voltage of the battery is up to 12.6V = 80% of capacity a true indication. The heavy current takes down the voltage of the battery causing shut-off before the battery is actually “depleted.” The Battery Watchers voltage display is not a true indication of batt capacity. The Batt Watchers AHR withdraws indicator and voltmeter lets you learn when the camera will shut off. SO you are carrying around 80% of capacity that never gets used. What a waste.
Other solutions: Some camera rental houses use NiMHd batteries at 16.4V; that is 12 cells ( 11 seem to be not enough) [expensive]. Some use dual lithium batteries, or large Li ones 3.5V x 5 = 17.5V [very expensive]. 7 lead acid cells (a 14V Batt) will do the trick. more details on my webpages.

we have a 2007 version of the composite only box transmitter with 10 frame delay for rent or sale.
its hard to get directors to get used to the 10 frame picture delay. We used it on Greys anatomy for 3 seasons, than they went cheap and reverted to the Modulupp.
Digital Video Transmitter and Audio Delay
Transmitter (built in antenna) Receiver (internal antenna) 2006 model, 300 yard range
Advantage: a perfect picture all the time ? no flickers ever
LEARNING CURVE: PICTURE DELAY
The Tx-Rx delays the picture on the monitor by 10 frames. It could be an annoyance for the director if he/she hears the actors on set dialogue outside his headphones just before he hears them in the phones. The delayed audio is in sync with the pix. Headphones that isolate help a lot here. They also prevent the actors from hearing themselves as an echo on the set.
As soon as headphones are worn or the monitoring is in a separate space away from the set the delay is no issue. Yes it does remove the director ?from the process? but this may be an advantage too. The director is distant from ?live? but perceives the event in a perceptual space that is more like the final program or film.
News: 2006 model in metal box has 300 yards range outside and a total of 5 channels can be used simultaneously. Cost approx. $ 6000.00.
2 Channel advice:
To get maximum range out of two cameras with 2 transmitters and 2 receivers on one stage do this:
Keep receivers 12 feet apart.
This will keep the receivers from talking to each other and freezing of the picture. Along with the picture freeze you get yellow lights on the receivers.
There is a ?this side away from camera? side to the way you mount the transmitter. Giving it ?air? helps.
There is a ?this side to transmitter? on the receiver. This is not so important.
Only at the very end of range where the picture goes from freezing to not freezing it may help. Experience has shown that pointing the hot side of the receiver towards the ceiling works well at long range on stages. What you do at short range (under 40 feet) does not matter a whole lot.
Picture Quality
Picture is perfect and looks good till the end of range, where it freezes till the Tx is in range again. There are no flickers and no rolling ever!!
Outdoor range: 30 yards = 90 feet New 2006 model: 200 feet
Indoor on stage range: 45 yards = 135 feet New 2006 model: 300 feet
These digital electronics like multipath. The system performs better indoors with lots of metal around reflecting the signal every way possible. In a 3-hour period you might experience one frozen frame event for 3 frames. This is the worst it will get. Picture at receiver output will be delayed a constant 10 frames. You need a matching audio (headphone) delay.
380 m sec. Delay
The picture is 10 frames delayed from live at the Rx on the monitor. It takes that time to digitize transmit and receive and un-digitize and make perfect images. (A-D Tx D-A) The equivalent delay for headphones is 380 m sec. You need an $80.00 audio delay to feed headphones with sync audio. It could be an annoyance if one hears the actors talk outside one?s headphones before one hears them in the phones in sync with the pix.. Headphones that isolate help a lot here. They also prevent the actors from hearing themselves as a echo on the set. As soon as headphones are worn or the monitoring is in a separate space away from the set this is no issue.
LED ON RX
Off ? no power
Yellow ? Warming up (needs 3 sec to start)
Red ? no link to Tx, Tx is off or too far away
Green ? all okay. Green is also on or turns yellow if Tx loses power. May turn Yellow blink to Red - Tx is out of range and Rx freezes image.
LED on Tx
Off ? no power
Red ? no link, Rx is off or too far away
Red blinking ? Trouble, Rx too far away or off.
Green ? all okay
THEORY OF OPERATION
The receiver continuously scans for free frequencies and communicates these to the Tx. The transmitter changes to these frequencies for the least amount of interference. The system seems to have more range in a metal-lined stage (cage) than in open air.
Coverage
In a suburban environment with little metal to reflect from, with only wooden construction houses the range is 25 yards thru 2 sheetrock walls.
On a chicken wire encased stage with wood sets and hanging lights: 45 yards.
The signal will not go through concrete + steel (parking garage) walls.
Extra Receiver Not Possible
Only one Tx-Rx pair works at a time. There are no other receivers possible. You must retransmit with other analog or expensive digital equipment: 900 MHz or other frequencies.
Voltage and power use: 9-16 Volts for Tx and Rx
TX 9V .65A
12V .48A
16V .37A
RX 9V .60A
12V .40A
16V .30A
We have cigarette size battery packs that are good for 4 hours for Tx or Rx and weigh 8 oz.
12V Battery with no memory effect
Li-Ion: 2 Ahr, max discharge 4 A with internal auto resetting fuse. 14.8V fully charged. Low voltage safety cutoff at 12V built in. No memory effect, 5+ years lifetime. Charge time 1.5 hr.
Tx Connector
Rear view of Lemo 8 way PLUG
All the grounds were connected in the early units (till the last 6 or so I think) in the connector.
Lemo part number is FHG.1B.308.CLAD52 for the right angle with boot.
1 Ground for Power + Video + Audio

8 Audio Ch2
Audio Level
Tx: Headphone feed from Beta works OK, probably an unbalanced ?10db level. There are 2 external level pots on the TX, screwdriver adjust, white ones on a small side. Since the picture is delayed 8-10 frames at the output of the receiver the audio when fed from Tx is delayed also and the headphones are in sync with picture. Rx audio out is balanced ?0? VU ref .775V (internally adjustable). The small black Rx has External audio adjustments, it is only a packaging difference.
Audio Delay
SHARK DSP110 a digital delay also called a delay line, the audio delay is set matching the picture delay so that the 2 are in sync on the monitor.
380 m sec is the best value to set the delay at.
How to save settings
It?s important to leave the DSP110 powered on for several minutes after creating new settings for any function so that they will be saved. When you power it up again the new settings will be remembered and re-appear.
To lock the front panel:
Push and hold the LOW CUT button (till all 5 LEDs above display are on) ? the LOW CUT YELLOW LED will blink. Do the reverse to unlock the unit to be reset.
How to increase the speed of UP-DOWN control
This works for any parameter where there is a big numeric difference between minimum and maximum.
Press and hold the UP or DOWN arrow keys, to initiate resetting of numbers .
While holding the UP or DOWN button, press the opposite direction button a couple of times. Each press makes the numbers increase or decrease at a faster rate. Cool -
TO ADJUST LOW CUT
Press low cut button briefly ? LED lights up. Hold the DOWN button till you see OFF in display. To count faster hold DOWN and press UP briefly several times. Range of cut off is 150Hz to Off. For speech use I suggest somewhere between 80 and 120 Hz for a roll off. There is no info on the slope of the filter.
TO TURN OFF GATE
Press GATE button briefly ? LED lights up.
Do not press and hold Gate button ? if led flashes, gate is in learning mode ? that?s would activate it.
You do not want it ON at all!
Press DOWN until you see OFF in display.
To count faster hold DOWN and press UP briefly.
TO MAKE THE GATE WORK
Using the Noise Gate Learn Function
With no program material going through the system ( the input turned down at the previous stage), press and hold GATE button until all parameter lights at the top are lit.
The DSP110 will automatically adjust the gate threshold to suppress any unwanted noise.
monitor what you just did so you know what it sounds like!
TO TURN OFF COMPRESSOR
Press COMPRESSOR once.
You see numbers from 0-100.
For density press and hold DOWN till you see 0.
To count faster, hold DOWN and press UP briefly often.
Press COMPRESSOR a second time ? the m sec light above display comes on. This is the attack time adjustment. It should not matter.
Mechanical Controls
Mic input gain pot in the rear with switchable +48 V phantom power for mic.
Digital headroom adjust pot on front left with 5 vertical LED display ? automatically keeps output level the same, it only controls digital headroom for maximum S/N. Do not let the red LED come on ever!
Shark Turnoffs:
It may be RF sensitive so keep it away from Comteks, transmitters, etc. The remote power supply has a transformer in it that radiates a magnetic field. It gets pretty warm, ventilate.
It has good sounding 24-bit A/D and D/A converters and XLRs and phono jacks.
It has an awkward-to-adjust compressor and a noise gate with LEARN Mode useful as a total quieting tool only.

DATA SECURITY
The encoding is of the 3DES encryption type and the Tx breaks the image file into many parts that are transmitted out of sequence on constantly changing frequencies (frequency hopping is guided by the Rx). This makes reception impossible for any normal mortal even with a large budget. If the CIA parks a helicopter on the roof, drills a hole onto the stage and lowers a receive antennae and retransmits the data to an NSA headquarters via satellite, one would guess that there is a small chance they can decipher the image a few days later.
LEGAL TO USE
This Transmitter ? Receiver pair is a legal to use anywhere by anybody under any circumstances, no license required in the USA or Europe. FCC Part 15 A.

The range is a direct reflection of power out. What trumps everything is a clean channel. You get 3x the range on a clean channel.
If you use a channel with a digital commercial HD TV transmitter 30 miles away on it, range is cut in half. There is no way to tell if a digital TV Tx is on an analog channel with an analog tuner. The license info on various databases is revealing. A walk test tells most.
The MiniSpy is better than anything else because it?s designed for one clean channel only: CATV59=434MHz. It is fine for Part 97 and experimentation and donation in the USA, not to be used commercially.
None of the other brands are to be used in the USA. Our tests were done in northern Mexico. Of course with the planned acceleration of global warming most of Ca. is gonna be ?off shore ? soon enough.

IDX Tx is only HD-SDI in... you need a down-converter to feed it composite from a video tap.
we will have early demos in LA ... when? we will announce here. IDX sais July...
let the vapors condense.........
Official press release:
http://www.idxtek.com/pdf/nab_08_cam_wave_hd_release.pdf
IDX Unveils Uncompressed Wireless Camera Transmission
IDX, maker of battery systems and portable chargers, will show a new low-cost, high-definition version of its CAM-WAVE wireless transmission system at NAB next week that sends uncompressed signals up to 150 feet in line-of-sight shooting, or 100 feet through walls.
Unlike other wireless camera system systems that make use of MPEG-2 or wavelet compression to send signals further that 150 feet, the CW-5HD transmits wireless full-bandwidth uncompressed HD-SDI and SD-SDI images over short distance, with very little latency (they say less than 1 millisecond delay). It supports all ATSC HD video formats with two channels of embedded audio.
The idea was to keep the new HD wireless system small and lightweight, hence the elimination of an internal encoder like those found on other HD warless systems. No compression also means no signal delay, which also plagues other wireless systems. This allows productions to seamlessly intercut cameras using CAM-WAVE HD systems with other wired cameras and avoid lip-sync errors.
The system would seem to be ideal for motion-picture shoots where signal quality captured from an unusual location maybe inside a car) is of the utmost importance. It could also be used in breaking news events where using a cable would be problematic. Users can't send SDI signals generated with the CAM-WAVE HD system over a limited-bandwidth microwave system (today they use asynchronous serial interface signals), so news crews would then send the signal back to the ENG truck, where it would be compressed and sent back to the station for airing of live pictures from the scene. The resulting compressed images would still look better than if they were originally compressed, according to Tony Iwaqmoto, vice president of marketing at IDX. (The unit was developed in IDX's Japan facility.
Designed to operate in the 5.1-5.8 GHz frequencies (meaning no special FCC license is required), the CW-5HD system uses very little power (11w) while sending encrypted MIMO/OFDM signals and weighs 1.7 pounds, with no visible antennas. It will ship with an IDX V-mount, enabling a direct attachment to an IDX battery (with two-hour run time) for rear mounting on a camera. It can also be powered directly by DC.
CAM-WAVE HD system, which will be available in Q3 2008 and cost approximately $6,000 (transmitter and receiver), will be shown in prototype at NAB (booth C8032).
For more information, visit http://www.idx.tv.
================
personally I do not believe it is uncompressed ... there has to be some datareduction (in Japanese this is not compression) the math just does not make sense.

The range is a direct reflection of power out. What trumps everything is a clean channel. You get 3x the range on a clean channel.
If you use a channel with a digital commercial HD TV transmitter 30 miles away on it, range is cut in half. There is no way to tell if a digital TV Tx is on an analog channel with an analog tuner. The license info on various databases is revealing. A walk test tells most.
The MiniSpy is better than anything else because it?s designed for one clean channel only: CATV59=434MHz. It is fine for Part 97 and experimentation and donation in the USA, not to be used commercially.
None of the other brands are to be used in the USA. Our tests were done in northern Mexico. Of course with the planned acceleration of global warming most of Ca. is gonna be ?off shore ? soon enough.

Jan 08 Rules for transporting Lithium Batteries on airliners:
(My interpretation ? no guarantees ? I am not liable etc?.)
1. Lithium Ion NP-1 Batteries must be ?installed in a device? to be allowed in checked baggage.
2. Spare Lithium Ion NP-1 Batteries (not in equipment) are allowed in Hand Carry in the cabin only. Tape up the contacts of the Batteries to prevent shorts.

From FAA:?The research also shows that an explosion will not result from shorting or damaging either lithium-ion or primary lithium batteries. Both are, however, extremely flammable. Primary lithium batteries cannot be extinguished with firefighting agents normally carried on aircraft, whereas lithium-ion batteries are easily extinguished by most common extinguishing agents, including those carried on board commercial aircraft.
Lithium Ion NP-1 Batteries contain 5.76 gr. of Lithium total (less than 8gr. aggregate).
Consider:
Keep NP-1 in the container with the snap on lids. Now they are now in ?equipment? and cannot be shorted or damaged by pressure. You can ship them in checked baggage. Maybe the ?cap? is enough.
Missing pic shows Np-1 holder which encloses the whole battery in plastic with a flip open lid as seen on the rear of Sony cameras.

These we sell www.wolfvid.com
Also: Discharge all Lithiums to the point where the built in safety circuits shut them down. Now there is no energy in them and they are near total safe. Use a small 12V light bulb. Recharge when arriving at location. Remember you are on the same plane as your Batts.

THE ADVANTAGES OF DIVERSITY RECEPTION
Here's an explanation from Coherent Communication manual:
How Diversity works: Imagine dropping a pebble into a still pond. If
the pebble is far enough away from the shore, the ripples continue
away from the point of impact undisturbed. But what happens if we
drop the same pebble near the shore? On the side facing away from the
shore, the wavelets will be as before, undisturbed. If we look at the
side facing the shore, what do we see?
If the shore is rocky, we may see that the waves are reflected back
from the rocks into the incoming waves. If we look closely, we will
see that the reflected waves combine with these incoming waves.
Depending on their position relative to each other, they may combine
and add to make a larger wave, or if the top of one wave and the
bottom of another meet, they will even out leaving no sign of a wave
at all.
This is what happens to radio waves as well. We have few reception
problems when the Transmitter and Receiver are situated over flat land
or water and the radio waves are undisturbed.
But in an urban environment, the radio waves are reflected from
buildings, cars, light posts and metal objects in general, and may be
absorbed by trees, shrubs and people. Inside a building, high
frequency radio waves will be reflected by filing cabinets, metal
studs in walls, lighting fixtures, metal desks, etc.
This is why when we try to use a cellular phone inside a building we
may experience good reception only a foot or two from a problem area
as the waves may combine and cancel in one area and add in another.
Now if we get tricky, we can place three antennas, several radio
wavelengths apart, and look at the signal coming from each one.
Statistical studies show that almost 100% of the time, one of the
three signals will be good as long as they are within range.
But we can't just combine the three signals and hope for the best,
because they will have a random relationship with each other and we
will have waves adding and canceling, just as when the wake from two
passing boats cross. This is called antenna diversity, and it just
doesn't work. Instead, our diversity receivers look at the output of
all three antennas and very quickly sample the signal strength of each
one and then look at the quality of the Video as well. An internal
microcomputer decides which antenna has the best signal, and switches
to it, giving you the best possible picture and sound. This happens so
quickly that you will not be aware of the bad image from the bad
antenna. The receiver switches 60 times per second while there is no
picture being written to the monitor. Often there are lights on the
front panel that show which antenna has been selected.
What can I do to improve reception when my receiver antennas have to
be close together?
Larry Fisher says:
You can tilt the antennas so that they are at 90 degree angles to one
another. That is to say, bend one 45 degrees to the left and the other
45 degrees to the right. The tilted antennas are a reasonable way to
operate and the best way if the antennas are fairly close together
since they couple together much less than if they are both pointed in
the same direction (parallel).
The antenna diversity used in our receivers does not select one
antenna or the other; it sums the two antennas together and corrects
the phase of one antenna so that the antenna signals do not cancel
each other out as they might do if they were 180 degrees out of phase.
So it does not make too much difference which way the antennas point
since the receiver will correct the phase.
Additionally, in any usual environment, the signals coming to the
receiver from the transmitter are not in any well defined phase
relationship or direction. The signals are reflected from cars, the
ground, metal studs, wire in walls, camera equipment and even people,
so that the signal that gets to the receiver is pretty well scrambled
and impossible to predict. The problem with reception occurs when all
the signals from all the reflectors get to the antenna and cancel out.
If you use two antennas, then the signals probably will not cancel out
at both antennas simultaneously. There is a new problem, though, if
you simply add the two signals together. When the signals at each
antenna are equal and exactly out of phase they cancel out at the
receiver. The phase diversity system that we use on our small
receivers detects this condition and simply inverts the phase of one
of the antennas. Now the antennas add the signals together for a 3 dB
pickup in power. For a good explanation of this, that is more
comprehensive than what I can do here, go to this link to our web site.
Dropouts and Noise-ups 1 http://www.lectrosonics.com/service/dropout.htm
It is part of our wireless guide. In fact you might want to down load
the entire wireless guide because it is pretty good and pretty neutral
in its treatment of wireless microphones (and everything that applies
to wireless microphones applies to UHF video). [notes in brackets like
this by the editor]
Wireless Drop-outs and Noise-ups [and flickers]
You have everything setup and connected. Your frequency coordination
has been done and you're performing a sound check from the
stage. As the talent [camera] moves across the stage with the wireless
mic [video transmitter] in operation you hear a "phffft" or maybe a
"swisshhh" [or see a flicker] from the wireless system. You have a
drop-out problem. No, not the high school variety, but rather a type
of RF signal degradation that causes the desired signal to drop way
down in strength to the point where the noise floor rises up and is
heard [ or the video goes away comes back and takes a few frames to
sync up again].
WHAT CAUSES DROP-OUTS [flickers]?
A wireless transmitter sends out a radio signal in all directions.
This signal will often bounce off nearby walls, ceilings, etc. and a
strong reflection can arrive at the receiver antenna along with the
direct signal. If the direct and reflected signals are out of phase
with each other at the receiver antenna, a cancellation may occur,
resulting in a drop-out [a flicker]. A drop-out sounds like either
audible noise (hiss, swish, pop, etc [looks like a loss of video
sync]), or in severe cases, may result in a complete loss of the RF
carrier and the sound when the transmitter is positioned in
certain locations in the room.
A VHF drop-out normally sounds like hiss or a swishing sound. UHF
dropouts are more brief due to the shorter wavelength, sometimes
sounding like a click or pop [ in video the pix goes away for a
shorter time with UHF]. Moving the transmitter even a few inches will
usually change the sound of the drop out, or even eliminate it [video
will reappear suddenly]. A drop-out situation can become either better
or worse as a crowd fills and/or leaves the room, or when the
transmitter or receiver is operated in a different location.
WHAT CAN I DO TO GET RID OF DROP-OUTS?
In non-diversity systems (one antenna) the best way to get rid of
dropouts is to reposition the receiver antenna so that it is as close
as possible to the transmitter. Be sure the transmitter antenna has a
line of site shot to the receiver antenna. Many times, simply moving
the receiver or transmitter antenna a few inches [up or down] or even
three to four feet will cure the problem.
Diversity systems (two antennas) were developed to attack this
particular problem. If one antenna is receiving two signals which a re
out of phase with each other causing a dropout, chances are good that
the other antenna on the diversity receiver is receiving a good solid
signal. There are several different types of diversity receiver
designs used by various manufacturers. Some of them switch antenna
phase, others alternate between two different receivers, and others
use non-switching, panning circuitry to blend the audio
outputs of two receivers. Circuits in the receiver will automatically
decide which antenna is receiving the best signal and either switch to
that antenna, or pan toward the stronger signal. If conditions cause
the multi-path problem to move to the other antenna, the receiver will
automatically switch over maintaining a good audio signal at its output.
For more information on Diversity systems and dropouts see the
Diversity Reception http://www.lectrosonics.com/wg/wg2000.htm
section of our Wireless Guide.
Even diversity receivers can be susceptible to drop-outs. Be sure to
position the antennas at least three or four feet apart and so that
they are not within 3 or 4 feet of large metal surfaces. If this is
not possible, try to position the antennas so that they are as far
away from metal surfaces as is practical. It is also good to position
the receiver so that there is a direct line of sight between the
transmitter and the receiver antenna. In situations where the
operating range is less than about 100 feet, the antenna positioning
is usually less critical, since the overall RF signal level is
generally higher. The antennas can also be configured with one whip
mounted directly onto the receiver, and the other one mounted remotely
[best use 2 or more flat panel antennas]. Lectrosonics builds VHF and
UHF receivers with a sophisticated diversity design ???
In the event that you do encounter a drop-out problem, first try
moving one antenna to a new location at least 3 or 4 feet from where
it was. This may alleviate the drop-out problem on that antenna. If
drop-outs are still a problem, try moving the antenna to an entirely
different location in the room or moving one or both antennas closer
to the transmitter location. By observing the OPTI-BLEND LEDs [only
the DX400 has signal strength LEDs] on the front panel of a
Lectrosonics ratio diversity receiver, you can determine which antenna
is suffering weak signals.
The above Paragraphs are written by Larry Fisher from Lectrosonics, a
RF genius and a nice guy. larryf@...

HDMI transmitters
Short range for consumers + homes (cheap) [ I do not sell anything of this stuff (no margin)]
Older ones have a .5 sec delay, new stuff has 1-5 msec delay. There are about 20 gadgets like this on the market Don’t buy anything that you can’t return!! I started a collection of links, I have no recommendations on what is best. The Robert Benson guy in San Diego in this list may be a good source. If someone really digs into this let us know. Remember HDMI connectors in a professional setting will cause severe pain. The terradeck uses the same wavelength 5.2-5.8 but different way of Tx. it has the same problems this stuff does: (range, reliability, HMI lighting). More on Tx in general read my previous post.

This is the 2.4 analog composite video link
http://vimeo.com/16487451
The wireless signal is transmitted in real time with no lag (almost none… there is a one milisecond latency, which is barely perceived by the human eye). The transmitted signal is 1080p with a data rate of 3g bps. On some DSLR cameras, like the Canon 5dmk2, the hdmi output from the camera is dropped from 1080p to 480p when the record button is pushed. During this time, there is a 3.2 second black out on the monitor as the HDMI monitor reacquires the downgraded signal and switches to the lower resolution.
Robert does not seem to use the Liliputs anymore. Do not use this monitor:
LILLIPUT 669GL-70NP/C 7" 16:9 LCD MONITOR WITH VGA/HDMI OR DVI INPUT
3 big problems with above monitor $ 200:
1. The menu is responding to commands very-very slow
2. The screen aspect ratio has 2 settings only 4:3 and 16:9, not Enough for HD pictures.
3. Not Enough signal formats, work only with some cameras
Generally there is a good reason why Liliputs suck. Note that most these monitors generate RF and ruin the range (sensitivity) of the Rx if nearby.

HD FLOW
HELLO FOLKS, BY TYLER CARTNER 10:05 AM ON DECEMBER 14, 2010
http://endlesspicnic.com/blog/2010/12/hd-flow-wireless-hdmi-5d7d-wireless-monitor-solution-on-the-cheap/#more-572
We recently saw this little HD wireless kit on Markertek’s web site and thought it might make the perfect wireless field solution for the 5D on the cheap. We ordered one and tested it. We thought we’d save ya’ll a little time and talk about the pros and cons.
HD video transmitted almost instantly through the air for under $400!? Yes indeed, and the image was pretty good too. It was re-compressed on the fly (h.264), but damn if it wasn’t fast at 30ms and the image quality was very good with the exception of some artifacts when the image got busy. We tested the range to about 100′ and it held up. Certainly it would be usable as a director’s monitor. But, and there is a BIG BUT, when used with the 5D, a problem comes when you hit the record button; it takes the unit about 13 seconds to re-handshake the HDMI signal and put up the image. We wouldn’t be able to live with this delay in a production setting, but maybe there are those of you who could. We were able to get rid of the delay by sending the signal via the composite output of the 5D, but of course the image quality is much lower and you lose the ability to also output over HDMI from the camera, damn.
We were dying to test the HD FLOW with the 7D and a friend of ours was gracious enough let us borrow his. The HD FLOW works beautifully with the 7D! Since the 7D doesn’t change resolution when the record button is pressed, there is no wait time, and the image stays up!
Here is a summary of the pros and cons of the HD FLOW when used with the Canon 5D:
PROS
30ms delay, almost instant video!
Image quality decent enough for director’s monitor, Possible to have up to 4 receivers, Instant image when using composite out
Good solid range of 100′ or more, Runs on batteries or A/C
CONS
Image showed artifacts when there was a lot of movement
Delay from the time you push record on 5D is about 13 seconds
Cheap plastic construction would certainly be challenged in a production environment, HDMI handshaking a bit unreliable
This could be a great solution for the 7D, but the 13 second delay makes it impractical for use with the 5D MkII.

Optitek had a genius gadget at CineGear:. They have a modified lens mount for the still Cannon lenses that let you focus the lens with their own internal factory electronic motors with a remote wired focus control. Now you can buy cheap cameras and focus cheap lenses professionally. WOW (also not on their website.

Heard that Tx placement is critical which appies to all these units as their power is very small. With attention and knowing their range is small they can be usefull on small stages or small houses. The sales people here make claims that they develped this, its hard to brlieve that since they did not even pay attention to the standard fim and video 10-30V supply. Ed.

Biggest downside: it's HDMI in and out. Even they're suggesting "just go get a Decimator 2 if you need HD-SDI to HDMI", and they're right. To build this wireless HD kit out right, you will spend another $495 for a Decimator 2, AJA HI5, Atomos Connect H2S (for $349 when it ships), etc. Likewise, you'll need an AJA HA5, BlackMagic HDMI to HD-SDI on the receiver, Atomos Connect S2H (for $349 when ships). They claim to have operated 6 systems simultaneously. Emitter draws 0.1, receiver is 0.2 amps. No timecode passed. This is AES 128 bit wireless encryption, FCC permit?
$995 + $495Decimator + $495 Decimator = $1985 (plus tax?).
