Abstract
Both a received program video and an electronic program guide can be simultaneously displayed in one screen of a monitor by a scaler/OSD circuit, and a user can change the ratio of the display areas of the program video and the electronic program guide to a desired ratio by operating a remote control transmitter. A CPU controls a tuner and a demultiplexer in synchronization with the change in the ratio of the display areas of the program video and the electronic program guide, to select a target channel of acquisition of program information for producing the electronic program guide.
