ABSTRACT:
A X-MAC encoder enables a plurality of components to be encoded, each having a sequence of packets, with the packets being distributed in successive bursts each occupying a predetermined fraction of a television frame line. It comprises a plurality of blocks each having at least one packet encoder provided with a buffer memory for storing digital data coming from a source, and an encoder for distributing the packets in bursts of adjustable duration not greater than the duration of one television line. A base encoder assembly contains a programmable device for allocating a determined window of the television frame to each block. It calls a burst of length corresponding to the width within the window that is allocated by the programmable device, on the basis of the respective block burst encoder, at the beginning of each window in a line.
