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