HDcctv Alliance

Maximum signaling distance depends on the cable quality.

Current solutions work over RG59 up to at least 100m.

It is anticipated that future solutions will operate at 300m before requiring repeaters.

The v1.0 Specification describes only the video uplink.

Successive versions of the Specification will address up-the-cable control, bi-directional audio, and up-the-cable power, and so forth.

The answer lies in the simultaneous emergence of:
• affordable image sensors capable of capturing surveillance-grade HD images
• cost-effective image processing circuits coupled to (or embedded in) those HD sensors
• low-cost HD-SDI transmission technology adapted from broadcast HDTV
• codecs capable of processing broadcast-industry-standards-compliant HD video stream
• inexpensive HD display panels (leveraging consumer trends)

The upgrade to HDcctv can be as easy as swapping the DVR as well as a camera or two.

That’s why HDcctv is Plug-and-Play.

An HDcctv System is a video surveillance system wherein broadcast-industry-compliant high-definition video (HDTV) signals are transmitted digitally over conventional CCTV media without packetization and without any human-perceivable compression latency.

The serial digital transmission link in HDcctv is derived from SDI foundational technologies that were developed for the professional broadcast market, where they are now widely deployed and well proven. Details about a representative SDI technology can be found on-line at http://www.gennum.com/video/technology/3G/index.php.

HDcctv is a standard for transmitting 720P and 1080P video over coaxial cable uncompressed and non-packetized. The technology is based on the work of SMPTE for broadcast studios, and behaves much the same way analog does, video starts streaming out of the source line by line to a receiver with next to no latency.
