    摘要: A method and receiving device are provided that determine a synchronization byte in a plurality of transport stream packets, wherein the synchronization byte has a predetermined synchronization value. The method/receiving device receives, via a receiver, a portion of a first transport stream packet of the plurality of transport stream packets; detects, starting from the beginning of the portion of a first transport stream packet, a continuous four byte pattern that does not include the predetermined synchronization value; detects a first occurrence of a byte having the predetermined synchronization value; detects a subsequent byte separated from the first occurrence by a predetermined byte length; determines a byte value of the subsequent byte; and validates that the first occurrence is the synchronization byte based on a comparison of the byte value and the predetermined synchronization value.

    摘要: A method and apparatus for streaming multimedia data over a network is provided. A playlist file for a selected multimedia presentation is downloaded by a client device over the network from a streaming server using a transfer protocol. The playlist file provides a list of URIs for media files each providing compressed video data corresponding to a segment of the multimedia presentation. The compressed video data includes reference frames used for video compression. A data file that is associated with the playlist file is also downloaded by the client device over the network from the streaming server using a transfer protocol and provides information identifying a location, a size, and a time stamp for each the reference frames contained in the media files listed by the playlist file. This information can be used by the client device to perform trick plays and to switch and stitch between variant streams.
