ABSTRACT:
A television receiver which can display images in different displaying forms on a display screen with an aspect ratio of 16:9 by controlling the video chroma processing circuit by the micro computer by operating the remote controlled signal acceptor or the key switch has memories. The first memory stores video control data for each displaying form and the second memory stores appointed data for designating predetermined video control data. When the displaying form is changed by operating the remote controlled signal acceptor or the key switch, the micro computer reads the video control data corresponding to the displaying form which is newly set from the first memory according to the appointed data of the second memory and changes, for example, the contrast characteristic in the signal processing circuit according to the read data. By doing this, in the television receiver which is applicable to both a high quality television system and the conventional television system, when displaying images of conventional television signals in different displaying forms on a display screen with an aspect ratio of 16:9, the most suitable image quality can be obtained for each displaying form.
