Abstract
A digital broadcasting receiver for changing a current channel from one channel to another channel when a commercial message is broadcast on the one channel on which a program is being watched. The time after changing the current channel is measured by a timer IC. When a predetermined time has passed, the current channel is returned to the one channel in response to the operation of a switch or the voice input from a microphone by a user. The program on the one channel is recorded in an RAM so that the program can be reproduced when the user wants to watch the program retroactively. As soon as the predetermined time has passed, an audio output processing section forms a voice message and informs the user of the fact from the speaker so as to draw the attention of the user to the fact.
