HDcctv Alliance Proposes Non-IP HD spec

| 2 Comments | 0 TrackBacks
A group of vendors goes public today with a proposed format for transmitting uncompressed high-definition video feeds over existing cabling or twisted pair infrastructure. Under the proposed architecture, further compression and encoding is not introduced until the signal reaches the DVR.

The HDcctv specification, the initial document of the HDcctv Alliance, an organization spearheaded by four manufacturers that represent various segments of the chip-camera-DVR supply chain, seeks to establish a signaling format akin to NTSC or PAL for high-definition video transmission. Version 0.9 is set for internal publication today to alliance members.

HDcctv is being positioned as a less expensive alternative to IP megapixel cameras, which packetize images into files in the camera before piping them to a DVR or video management system. HDcctv won't turn ordinary analog cameras into HD, but it will allow 780p and 1080p images to be transmitted over coaxial and twisted pair cable without encoding. The specification will also work with standard definition digital cameras.
