ABSTRACT:
An automatic aspect ratio switching apparatus for automatically switching an aspect ratio is provided. The apparatus includes a satellite intermediate frequency processor which demodulates the broadcast signal from an intermediate frequency signal received from the satellite. A decoder detects aspect ratio support data which is included in the satellite broadcasting signal. Based on this detected aspect ratio support data, the deflection of the electron beam in the display of the television receiver is automatically caused to correspond to the aspect ratio of the broadcast signal. Accordingly, an aspect ratio can be automatically switched according to the aspect ratio support data inserted on the broadcasting signal sent by a broadcasting station without manual operation of a key.
