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.
摘要翻译：在视频分配装置中，存储器缓存基于预定单元对从通信网络接收的视频数据进行分割的视频数据的段，并存储视频数据段的视频识别信息。在从网络接收到高速缓存分发请求时，分配控制器导出包含在高速缓存分发请求中的视频标识信息。继电器控制器从存储器获取与视频识别信息相关联的视频数据段，以将所获得的视频数据段以视频数据源附近的视频数据段上定义的传输速率传送到请求者。视频可以以接近由内容分发服务器定义的传输速率的传输速率分布，同时可以减少视频流量。
