Abstract
A video data display controlling method and system in which an image in each image area or in each partial image area of each image area to be displayed on a display screen and designated by a user is displayed at a display quality differentiated from other areas not designated. A video data display control unit stores display state data of each displayed image in a display state management table. The video data display control unit changes the display specification or attribute of each image so as to display an image having a high user interest degree with a high display quality and display an image having a low user interest with a low display quality, and transfers the changed display specification to a display specification management table of a video data input unit. A video data input unit controls a video data compressing unit to compress digital video data in accordance with the changed display specification or attribute.
