Automatic wide screen display method and apparatus for a TV set

摘要

An automatic wide screen display apparatus and method of a TV set according to the present invention determine the presence of a wide screen video signal and detect an aspect ratio data of an inputted video signal based on the determination using a vertical synchronizing signal. The apparatus and method further perform communications using a protocol defined between a main microcomputer for controlling the screen deflection and an exclusive wide screen microcomputer for detecting the aspect ratio of the inputted video signal in order to automatically display the wide screen image in accordance with the inputted video signal, and control an integrated deflection device in accordance with the communication result to control the screen deflection.
