The invention which is the subject of this application is to provide for the dynamic adjustment of the display of a graphic display on a display screen, such as that of a television set. Typically, the display screen shows a video display such as that of a television programme generated from received video data such as via a broadcast data receiver, DVD, VCR or the like. On occasion and typically in response to a user selection a graphic display can be generated and overlaid on the video display to provide information to the user. Changes in the video display to take into account different video display formats and/or the particular format of the display screen can cause the graphic display to be unacceptable but this is avoided in the current invention which allows the graphic display to be altered with respect to the format such that it is visible and in a preferred form. |
