Abstract
An arrangement for transmission of television composite signals contains coders which convert luminance component Y, and chrominance difference components U, and V of a television signal into variable-length code words. These are interlaced in a multiplexer in pulse frames by assignment to fixed locations. At a receive side, a time-division multiplex signal formed is in turn separated in a demultiplexer. Decoders reconvert the variable-length code words into the Y, U, and V components. The luminance and chrominance components can be reliably separated at the receive side due to the assigning of fixed locations in the pulse frame, these components being reliable separated even when the word synchronization of the individual components is lost.
