摘要： PROBLEM TO BE SOLVED: To solve a problem that smooth reproduction of media stream data is difficult because packets are aborted due to non-existence of a free capacity in a buffer when processing of packetized media stream data continuously transferred is not in time in the case that the mount memory size and the processing capacity are limited for a mobile terminal or the like for transmission/reception of the media stream data between terminals connected via a network.
SOLUTION: The method disclosed herein dynamically revises a coded bit amount, a sampling frequency and a frame rate or the like of media stream data 10 in matching a network band and transmits the resulting media stream data 10. Thus, audio and moving picture included in the media stream data or a delay time up to reproduction of the audio and moving picture are kept constant for a reception terminal, thereby allowing the reception terminal to be capable of continuously reproducing the audio and moving picture without causing interruption.

摘要： PROBLEM TO BE SOLVED: To adjust the reproducing time length of audio data and to cancel a synchronous deviation between video data and audio data by generating dummy audio data consisting of dummy data which is neglected at the time of decoding.
SOLUTION: The data part 34 of dummy audio data is constituted of Error Check 31, AudioData 32 and Ancillary Data 33 and their sizes are different in layer and sampling frequency. Besides, Audio Data 32 is variable length data and data '0' is stored in Audio Data 32 when the size of audio data is less than the size of AAU. Thus, the configuration is made to be the dummy audio data one where '0' is stored in the header of AAU and its data part so that audio data which are reproduced as the soundless one in result are generated without a compression processing.
