In a case of connecting a computer (11) to a television receiver (12) for use, when a DVD repreduction or video game is started, a device driver (16) detects a call from an application (13,14) to an API (18,19) in an OS (15), and the output system for the television receiver (12) is switched to an over-scan, thereby over-scan displaying moving images or video game on the television receiver (12). When the DVD reproduction or video game is terminated, the device driver (16) detects a call to the API (18,19) for releasing the resources, and the output system is returned to an under-scan, thereby under-scan displaying a computer screen on the television receiver (12). As a result, the display system of a television receiver can be automatically switched between over-scan and under-scan in accordance with the contents on the screen. |
