摘要： PROBLEM TO BE SOLVED: To provide a distributed cache system which is configured with a plurality of cache servers and can be applied to a large scale network. SOLUTION: The distributed cache system configured with a plurality of cache control servers manages content information managed by each cache control server in a divided manner. A cache cooperation router transfers a request for a content to the cache control server managing the content information when the content requested from a client is stored in the distributed cache system. The cache control server is provided with a function for notifying its own address to a distributed cache system when the distributed cache system is added. The cache control server having received the notification transmits the content information to the added cache control server to synchronize the content information, thereby enabling the more cache control servers to be installed.

摘要： PURPOSE:To provide a video/acoustic communication equipment capable of attaining video/acoustic communication matched with a displayed video and having a high sense of presence by automatically adjusting sound to be reproduced without adjusting sound volume or the like to be reproduced by a sound receiving side user. CONSTITUTION:The viewing positions of a sound transmitting side user B and a sound receiving side user A are detected. An acoustic signal processor 4 adjusts an acoustic signal 21 collected by a microphone 1 based upon the detected viewing position information of the users A and B. An acoustic signal reproducing device 5 reproduces the adjusted acoustic signal 24. Consequently sound reproducing matched with the relation of viewing positions between the video receiving side user and a communicated user on a displayed video can be attained and video/acoustic communication having a high sense of presence based upon the synergetic effect of a video and sound can be attained.
