SYSTEM FOR CONTROLLING VIDEO DISTRIBUTION IN RESPONSE TO A REQUEST ON REDUCED VIDEO DATA TRAFFIC AND A METHOD THEREFOR

摘要

In a video distribution apparatus, when a video data segment into which video data of a content is sectioned on the basis of a predetermined unit is received on a network, the received video data segment is cached into a memory, and at least content identification information of the video data is stored into the memory. When a cache distribution request is acquired on the network, a distribution controller obtains content identification information included in the request. A relay controller acquires a video data segment associated with the obtained content identification information from the memory, and transfers the acquired video data segment to a source of the request at a transfer rate at which the video data segment is transferred in the vicinity of a distributing source of the video data.
