Abstract
In a digital broadcast receiver 10, an MPU 26 has a configuration for detecting the number of subchannels and the numbers of the subchannels which a received main channel has from control data received and switching to a subchannel with the minimum number when the number of subchannels changes and switching to a subchannel with the minimum number of the residual subchannels when the numbers of the subchannels received run out and displaying the numbers of the received main channel and the subchannel on a display 25.
Claims6
A control method for performing automatic switching of a subchannel by an MPU when a subchannel of a received main channel changes in a digital broadcast receiver for receiving a broadcast by operating an operation part to specify a main channel indicating a broadcast station and subchannels indicating broadcast programs, characterized in that the MPU comprises the steps of:
- detecting the number of subchannels and the numbers of the subchannels which the received main channel has from control data received;
- switching to a subchannel with the minimum number when the number of subchannels changes;
- switching to a subchannel with the minimum number of the residual subchannels when the numbers of the subchannels received run out;
- and
- displaying the numbers of the received main channel and the subchannel on a display.

- detecting the number of subchannels contained in a received main channel;
- and
- switching to a subchannel with the minimum number when the number of subchannels changes.
