Abstract:
An image/audio reproducing apparatus for decoding/reproducing coded data in which digitally compressed/coded image and audio data are multiplexed, comprising:a data storage unit for storing coded data;a BS memory for temporarily storing the coded data read out form said data storage unit;an image data area lookup table for storing address information of a data string having continuous image data in said BS memory;an audio data area lookup table for storing address information of a data string having continuous audio data in said BS memory;a system decoder for loading the coded data from said data storage unit to said BS memory, analyzing a header of the coded data to detect an image data and an audio data, and upon detecting the image data, storing address information of the image data in said image data area lookup table, and upon detecting the audio data, storing address information of the audio data in said audio data area lookup table;a video decoder for accessing said BS memory in accordance with the address information in said image data area lookup table to read out the image data stored in said BS memory and decoding the image data; andan audio decoder for accessing said as memory in accordance with the address information in said audio data area lookup table to read out the audio data stored in said BS memory and decoding the audio data,said system decoder operable for preventing overwriting of said image and audio data in said BS memory by additional image and audio data from said data storage unit when said video and audio data in said BS memory has not been read by said video decoder and said audio decoder respectively.
