Abstract
A video signal output apparatus is provided. Video format information that can be displayed on a video display apparatus is detected by an I/O unit from an input data. A comparing unit compares the detected video formats with video formats that can be converted by a converting unit, and then common video formats are set as selectable video formats and output as menu video. A user sees the menu video and selects a video format. Simultaneously with the converted digital video data, video format information is also inserted into the output data and then outputted. Accordingly, the video display apparatus switches the video format of the screen. The user can select a most suitable video format from the menu screen by only connecting the apparatuses, and then the video format of the video display image apparatus is also switched automatically.
