PURPOSE: To multiplex/demultiplex and output LSD, HSD, or the like, which doesn't require delay compensation between channels, without delay compensation with respect to a video signal or an audio signal. CONSTITUTION: A demultiplexing circuit 10 demultiplexes data from input CH1 reception data H in accordance with demultiplexing specification information C of data set by a processor 1 and gives LSD (U2) and MLP (V2) to a selecting circuit 12. A demultiplexing circuit 11 demultiplexes data from input CH2 reception data K in accordance with information C set by the processor 1 and gives BSD (W2) and H-MLP (X2) to the selecting circuit 12. When a delay selection control signal Y from the processor 1 is '0', the selecting circuit 12 selects and outputs LSD (U2), MLP (V2), HSD (W2), and H-MLP (X2) from demultiplexing circuits 10 and 11. When the signal Y is '1', the circuit 12 selects and outputs LSD (U1) after delay compensation, MLP (V1) after compensation, HSD (W1) after compensation, and IH-MLP (X1) after compensation. |
