Abstract (en)
[origin: WO2005101411A2] A method and apparatus for a multicasting multimedia content distribution system. A content server creates a schedule of transmission times for data streams and assigns the streams to multicast groups. DVRs receive the schedule from content server that contains content descriptions for each data stream along with the transmission times of each particular content description. The content server transmits the content across the Internet according to the published schedule via a multicast transmission designated for a particular multicast group. Each DVR determines the content for which it has an interest, finds the scheduled time for transmission for the content, schedules a recording time in its recording schedule, and joins the associated multicast group at the scheduled time. The DVR receives the multicast stream for the group and stores the stream on its local storage device for use by the DVR or for viewing by a user.
