Hi,
Wondering if someone can provide some suggestions for low range (<5m) HD video transmission, low latency, no audio, one-way.
Due to the nature of the implementation I am completely discarding wi-fi cameras, the solution needs to be an OTS camera module plus some sort of wireless module or IC
Analog video is great for low latency one-way with reasonably graceful degradation.
Early HD video was analog. It just was not bandwidth efficient.
I’m totally guessing, but I would think something like SDI digital video with some intelligence for gracefully handling loss-of-signal/loss-of-sync using predictable re-synchronization would be how to do real-time digital HD transmission…
Last I checked, these were all still analog and not at all spectrum efficient. It’s been a few years, but the basic tradeoff between compression and latency still holds.
Though I see Airbeam are claiming 5 ms latency. This has got to be for the already compressed video stream, so the compression latency would be on top of this.
Lots of FPV folks moved to DJI after they released a pair of goggles and a unit that goes on the drone (any FPV drone, not a DJI turnkey). If I recall it’s an HD resolution.
I’ve seen a couple of these floating around, more for the movie director to see what the drone camera is seeing, not sure if either of these are useful, good luck!
