Abstract

An image and sound synchronizing reproduction apparatus includes a reference time calculation circuit for calculating a reference time in response to a data amount of decoded sound data, a delay detecting circuit calculating number of image frames to be processed practically in the decoding process in response to the reference time and comparing the number of image frames with number of frames practically processed in the decoding process, for detecting a delay of image decoding process, a frame-removing control circuit for performing a discriminating process of frames to be omitted the decoding process in response to the number of delay frames detected by the delay detecting circuit, and an image data input control circuit for performing an omission to read compressed image data corresponding to the frames discriminated by the frame-removing control circuit, controlling finely the image and sound synchronizing reproduction regardless of the structure of compressing coded data.
