Abstract
A composite video multiplexing arrangement for allowing a plurality of low bit rate video signals to be multiplexed into a single coded signal to be transmitted to an associated receiver. For use with arrangements such a security system, each video “source” (such as a camera) includes a coder module for forming a digital representation of the video, including both “source” and “line” information. Each coder module includes a FIFO buffer for holding this data until multiplexed onto the single output signal. An associated decoder is capable of extracting the “source” and “line” information and regenerating each separate video signal.
