One of the announcements we weren’t able to personally cover at NAB was the Cam~Wave HD from IDX. Cam~Wave is a wireless system capable of transmitting a variety of uncompressed HD flavors up to 150 feet (up to 1080/30p). It piggybacks on cameras like the JVC HD250U and is powered by IDX batteries of course. The entire system, including transmitter and receiver, retails for around $6000. More details from the press release:
* Uncompressed wireless system for both HD-SDI and SD-SDI video.
* Multiple formats of video with two channels of embedded audio.
* Latency less than 1ms.
* Transmission range up to 100 feet (30m) through walls and up to 150 feet (50m) in line-of-sight conditions. Use in actual production may vary.
* Conservative 11w power consumption.
* Ships with an IDX V-mount, allowing a direct attachment to an IDX battery for rear mounting on a camera. It can also powered directly by DC.
* Sleek and lightweight: weighing just 1.7 pounds, and no visible antenna.
* Wireless transmission via MIMO/OFDM (Orthogonal Frequency Division Multiplexing), operating between the 5.1-5.8 GHz frequencies. No special license is required.
* Selection of four manual or auto-select frequencies with 256-bit encryption.

Does MIMO/OFDM imply bidirectional camera control support (i.e. paint, iris) or does this unit simply supply a wireless feed to your destination?
Hey Carl,
I forwarded your question to IDX, and Sales/Marketing manager Vickii Chaffee had this to say:
“In regards to the MIMO/OFDM structure, our system is not bi-directional for camera functions such as iris, paint, etc. We are taking either an HD-SDI or SD-SDI feed from the camera and inputting the signal into the TX. From there, it transmits MIMO to the RX. Within the antenna array, one of the antenna is working in a type of bi-directional manner with monitoring signal processing and internal signal housekeeping issues; however, this is limited to internal signal monitoring and not inclusive of camera functions.”
Hope that helps.
