摘要:
In a transmitting system, a first multiplexer multiplexes first through M-th encoded digital video signals from encoders to produce a primary multiplex signal comprising cells which have channel codes, address codes, and cell data, where M represents an integer greater than two. Each of the cell data represents a part of one of the encoded digital video signals. Each of the channel codes indicates one of the encoded digital video signals. Each of the address codes indicates a position of one of the cell datum. A first demultiplexer demultiplexes the primary multiplex signal to produce first through N-th primary demultiplex signals, where N represents an integer which is less than M and greater than one. A second multiplexer multiplexes the first through the N-th primary demultiplex signals from the first demultiplexer through first through N-th transmitting paths to produce a secondary multiplex signal. A second demultiplexer demultiplexes the secondary multiplex signal datum in response to the channel codes and the address codes to produce the first through the M-th encoded digital video signals.
