    摘要: The disclosure discloses a method for hierarchical transmission in a mobile multimedia broadcasting system, including: dividing a video stream in a video service into a basic layer code stream and at least one enhanced layer code stream; encapsulating them in different multiplexing subframes of a broadcasting channel frame according to respective layers to which they belong; and sending the location information of the multiplexing subframes to a receiving terminal. The disclosure further discloses a method for hierarchical reception in a mobile multimedia broadcasting system, including: monitoring, by the receiving terminal, the location information of the multiplexing subframes of a broadcasting channel frame, code streams of a plurality of layers of a video stream of a video service being encapsulated in said multiplexing subframes, receiving only the basic layer code stream or both the basic layer code stream and the corresponding enhanced layer code stream, decoding only the basic layer code stream or both the basic layer code stream and the corresponding enhanced layer code stream, and outputting the video data of the basic layer code stream or that generated by combining the basic layer code stream with the corresponding enhanced layer code stream. The disclosure further discloses a device implementing the methods above. The disclosure is simple to implement and is practical.

    摘要: The present invention discloses a method for improving utilization of broadcast channel frames comprising determining whether auxiliary data exists in multiplexing data of a multiplexing frame upon generation of the multiplexing frame and encapsulating the auxiliary data in a filled portion of the multiplexing frame if yes. The present invention also discloses a method for using a filled portion of a multiplexing frame comprising a receiving terminal decoding multiplexing data in the monitored multiplexing frame, monitoring redundant data in the filled portion of the multiplexing frame when determining that an error code occurs in the decoded multiplexing data, and recovering data with the error code in the multiplexing frame using the redundant data. The present invention also discloses an apparatuses for implementing the above methods. The present invention improves channel utilization.
