    摘要: A method and apparatus to improve error resiliency in processing a multimedia bitstream is described. A directory of header information is generated for a multimedia bitstream. The directory information comprises packet header information associated with the multimedia bitstream. The directory information may be transmitted to a receiver along with the multimedia bitstream. A receiver of the multimedia bitstream and the directory can utilize the header information to identify and locate packets within and subsequent to erroneous data in the received bitstream. By identifying and locating packets that may otherwise be discarded, the receiver may be able to improve error recovery and decoding of the multimedia data.

    摘要: Methods and apparatus for packetization of content for transmission over a network. A method is provided that includes generating one or more content packets from the multimedia content, wherein the content packets are associated with a time reference, and adding a sync header to the one or more content packets to form one or more application layer packets, respectively, wherein the sync header comprises a time indicator that indicates time relative to the time reference. An apparatus includes encoding logic configured to generate one or more content packets from the multimedia content, wherein the content packets are associated with a time reference, and packetization logic configured to add a sync header to the one or more content packets to form one or more application layer packets, respectively, wherein the sync header comprises a time indicator that indicates time relative to the time reference.
