Title:
マルチキャスト配信を通じてメディアを提供するシステムのための方法及び装置
Document Type and Number:
Japanese Patent JP5650197
Kind Code:
B2
Abstract:
The present invention relates to a server and a method for achieving a fast channel change in e.g. an IPTV system. This is achieved by selecting a source for retrieving the requested channel based on the current load of the FCC server. The source may be the streaming server providing the regular multicast stream or a buffer providing a buffered version of the requested channel. According to one embodiment requests for fast channel change (relating to the same channel) are grouped and served and served as a bundle over multicast. By doing that one can alleviate the load on the FCC server and the network since multiple clients can share the same stream.
