The Model 496-2C Video Signal Multiplexer (2 Channel), or Video Combiner, doubles the transmission capacity of a conventional video channel by combining (multiplexing) two NTSC or PAL video signals into one video signal. Use the 496-2C to multiplex video signals at the transmit end of a video transmission channel. A Video Demultiplexer Model 497-2C at the receive-end of the channel separates the two combined signals for normal viewing or recording. The multiplexed video signal can also be recorded using conventional equipment and then played back for demultiplexing

The Video Multiplexer output may be viewed directly on a video monitor. The two (2) video input channels appear side by side, each squeezed to one-half of its original width in order to fit together in a normally sized frame. Video inputs to the video multiplexer from analog tape must be time base corrected.
