Ben Cain offers a detailed exploration of professional grade wireless HD solutions.

Someday we might look back at the time when we were forced to use masses of chaotic, unruly conduit with a certain nostalgia. But then likely be glad those days are long behind us.

Wireless HD = no cable between the camera and video monitoring. Instead we have a transmitter (Tx) on the camera coupled with a receiver (Rx) on the monitoring end that captures the 1920×1080 video signal out of the air and outputs it via HD-SDI to our on-set video system and/or monitors.

Wireless HD is finally here in a big way but with so many options now available, more on the way, and at so many different price points, which system is the right fit for your needs? This depends on many factors but among the current crop, don’t expect to find the perfect solution. At least not just yet.

Amazing breakthroughs have been made in this technology as the equipment is getting smaller, lighter, and capable of far greater range yet each product offering presents a specific set of advantages and disadvantages. At this time, the “perfect” (for me anyways) wireless HD-SDI video system would have the following features:

Video output from Rx: 1920×1080, Uncompressed, 10 bit, 4:2:2, SMPTE 292M 1.485 Gbit/s HD video with embedded audio and timecode.

That is, a video carrier from the wireless system that is identical to which is delivered over standard 75ohm BNC cable -
