Abstract
Color television transmission and data storage system, respectively, with time-division multiplex encoding. A signal source is coupled via an encoding circuit for time-division multiplex encoding and signal compression to a transmission and storage channel, respectively to which a data receiver having a complementary decoding circuit is connectable. Luminance information associated with a number of p line periods is transmitted substantially non-compressed. A portion of the chrominance information associated therewith is transmitted in considerably compressed form in a number of q further line periods. In this situation there is an average chrominance time compression factor which is substantially equal to or less than q/p. On display, p lines are displayed with substantially the full bandwidth for the luminance and a limited chrominance bandwidth which is inherent to the time compression. The channel is then used optimally to obtain a high picture quality on display.
