ABSTRACT:
A television signal transmission system comprises a multiplexer for combining a compressed video data signal and one or more auxiliary data signals to form a multiplexed signal for transmission over a channel of fixed bandwidth. The multiplexer is controlled to vary the ratio of the components comprising the multiplexed signal to insure satisfactory reproducible image quality in response to the received compressed video data signal. The compressed video data signal may be buffered prior to combination with the auxiliary data, in which case the multiplexer is also further controlled to vary the ratio of the components comprising the multiplexed signal to maintain the fullness of the buffer at an acceptable level.
