ABSTRACT:
The invention provides a digital broadcast receiver for receiving broadcast waves comprising multiplexed broadcast signals of a plurality of channels including a main channel and a subchannel. The receiver comprises demodulator circuits for demodulating received data of one of the channels selected and outputting the resulting data, a memory capable of storing received data as to a program transmitted on the subchannel, and a controller for writing the received data as to the program transmitted on the subchannel to the memory while updating the received data at all times, and reading the received data stored in the memory from the head of the program and feeding the read data to the demodulator circuits upon a changeover from the main channel to the subchannel. When the main channel is changed over to the subchannel, the program broadcast on the subchannel can be listened to always from the beginning.
