The Model 497-2C Video Demultiplexer (2 channel), or Video Channel Separator, doubles the transmission capacity of a conventional video channel by separating two NTSC or PAL video signals out of one multiplexed video signal. Install the Video Demultiplexer at the receive end of the channel to demultiplex video signals from the Video Multiplexer Model 496-2C at the transmit-end of the channel. The multiplexed signal can also be recorded using conventional equipment and then played back for demultiplexing through 497-2C Demultiplexer. Video inputs to the Video Signal Demultiplexer from analog tape must be time base corrected.
