Abstract:
An image and sound synchronizing reproduction apparatus for decoding image and sound data both coded in digital compression and reproducing the image and sound data in synchronism, comprising:a reference time calculation circuit for calculating a reference time in response to a data amount of decoded sound data;a delay detecting circuit for calculating a number of image frames to be processed practically in a decoding process of the image data in response to the reference time and comparing the number of image frames to be practically processed with a number of frames practically processed in the decoding process of the image data, for detecting a number of delay frames of the decoding process of the image data;a frame-removing control circuit for performing a discriminating process of frames to be omitted from the decoding process of the image data in response to the number of delay frames detected by the delay detecting circuit; andan image data input control circuit for omitting the reading of compressed image data corresponding to the frames discriminated by the frame-removing control circuit.
