Channel-Zero encoding, in video surveillance or NVR systems, is an option to configure the video recorder to stream a video feed composed of multiple camera views (channels) in one split-picture view. This allows the recording system to send one frame to a remote system, rather than numerous frames of the individual channels; thereby reducing ...

Each country, faced with local political, technical, and economic issues, adopted a color television standard which was grafted onto an existing monochrome system such as CCIR System M, using gaps in the video spectrum (explained ...
