1. An information processing apparatus comprising:
a display device;
a first display controller which converts an externally input first video signal into a second video signal which can be displayed on the display device;
a second display controller which converts the first video signal into a third video signal which can be displayed on the display device; and
a switch means for switching between a first path for outputting the second video signal converted by the first display controller to the display device, and a second path for outputting the third video signal converted by the second display controller to the display device;
an external signal input terminal which is common to the first and second display controllers and is used to supply the externally input first video signal to the first and second display controllers; and
a television tuner unit which includes a conversion circuit which converts the first video signal input to the external signal input terminal into playback data that allows an internal process, a compression circuit which compresses the playback data converted by the conversion circuit, and a tuner which receives television broadcasting, the television tuner unit being arranged between the external signal input terminal and the first display controller.
