摘要： PROBLEM TO BE SOLVED: To provide a communication system wherein transmission of excess data is not needed, a processing load of terminals is relieved, and the terminals can share and display an image data part noted at communication. SOLUTION: In the case of carrying out real time communication, the communication carried out by taking notice of part of transmitted/received image data is explicitly indicated, a terminal 101 for transmitting the image data transmits the data of a reduced image 5 or an image 7 resulting from segmenting a required part by taking into account the noted part of the image and a size of a display apparatus of a terminal 102. Thus, transmission of excess data is avoided to relieve the processing load of the terminal. COPYRIGHT: (C)2005,JPO&NCIPI

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.
