PROBLEM TO BE SOLVED: To provide a video signal output device capable of setting a interlaced/progressive mode and setting an aspect ratio in television screen setting interactively with a user. SOLUTION: When television screen setting is not set and thus a television screen setting completion flag is not set, and a terminals-connection judgment port takes a low level, an i/p selection screen is initially displayed on a progressive display device. However, the i/p selection screen is not displayed on an interlaced display device. When processing performed for the i/p selection screen is completed, or when the terminals-connection judgment port takes a high level, indicating that the video input D-terminal of the display device is not connected to the video output D-terminal, an aspect ratio setting screen is displayed. After aspect ratio setting is completed, the television screen setting completion flag is set. This eliminates the need to perform the television screen setting again. COPYRIGHT: (C)2007,JPO&INPIT
