  • Patent number: 8886754
    Abstract: A method, apparatus and computer-readable storage medium distribute a non-live content stream in a network. An initial meta-file is transmitted in response to a request for the content, which identifies a division of the content stream into blocks, and available sources for delivery of the blocks. The initial meta-file can identify a first multicast and a second multicast server, assigning a first and second portion of the blocks for delivery using the first and second multicast source server, respectively. The first and second portions are transmitted using the first and second multicast source servers, respectively. The first and second portions correspond to distinct non-overlapping portions of the non-live content stream. The initial meta-file can also identify a unicast source server, assigning a third portion of the blocks for delivery using the unicast source server, the third potion being transmitted by the unicast source server.

  • Patent number: 8386629
    Abstract: The invention relates to a method of distributing a non-live content stream in a network. The method comprises transmitting an initial meta-file in response to receiving a request for a non-live content stream. The initial meta-file comprises information, and the information identifies a division of the content stream, identifies a multicast source server and a unicast source server. The method also comprises transmitting at least a first portion of the non-live content stream using the multicast source server and at least a second portion of the non-live content stream using the unicast source server. Also, the invention relates to a system comprising a multicast source server adapted to transmit at least a first portion of the non-live content stream in response to transmission of an initial meta-file. The initial meta-file is transmitted in response to receiving a request for a non-live content stream.
