VIDEO DISTRIBUTION SYSTEM REDUCING VIDEO DATA TRAFFIC AND A METHOD THEREFOR |
摘要 |
In a video distribution apparatus, a memory caches segments of video data into which video data received from a communication network is sectioned on a basis of a predetermined unit and stores video identifying information of the segments of video data. A distribution controller derives, upon receipt of a cache distribution request from the network, video identifying information contained in a cache distribution request. A relay controller obtains segments of video data associated with the video identifying information from the memory to transfer the obtained segments of video data to a requester at a transfer rate defined on the segments of video data in the vicinity of a source of the video data. The video can be distributed at a transfer rate close to a transfer rate defined by a content distribution server while the video traffic can be diminished. |
