摘要： The object of this invention is to realize the correct and prompt synchronization of data in decoding and reproducing multiplexed coded data multiplexed with a plurality of media coded data in the unit of packet without regard to the configuration or characteristics of the apparatus. To achieve a data decoder that can synchronize the video and audio data correctly, the timing controller obtains a buffering time indicated by the time difference between the decoding end time and the specified presentation time contained in the data, and data buffering is performed by buffer memory. The video decoding end time is latched from the system time counter according to a timing pulse generated by the video decoder when the first decoded data is output from video decoder after the data decoder is activated.
