Abstract: The present invention discloses a method and an apparatus for bearing a Transport Stream (TS). The method includes: extracting TS packets continuously from the TS to constitute one or more sampling units, and obtaining index information of the sampling units; writing the sampling units into a data portion of a streaming media file, and generating an index portion of the streaming media file according to the index information. The present invention can encapsulate the TS into the streaming media files, so that the TS can be read by a standard streaming media file analyzing program, which facilitates multi-party interaction of the TS data in the streaming media field, and improves the practicability of the TS in the streaming media field.

Abstract: Disclosed are an anti-packet-loss real-time communication method, system and related device based on hierarchical coding. A transmitting end initially sets a coding parameter and a packaging parameter according to a network condition difference, and generates a payload containing coded data and protected data simultaneously according to the coding parameter and the packaging parameter and transmits the payload to a receiving end; the receiving end counts network status parameters according to the received payload and transmits the network status parameters to the transmitting end; and the transmitting end adjusts the coding parameter and the packaging parameter in real time according to the network status parameters, and generates a payload containing coded data and protected data simultaneously according to the adjusted coding parameter and packaging parameter. The present disclosure performs self-adaptive processing on packet loss or congestion occurring in a network during real-time communication, i.e.

Abstract: A method for storing audio data is disclosed, including: recording basic information of a versatile audio data storage file into the versatile audio data storage file; storing Versatile Audio Codec (VAC) frame data into the versatile audio data storage file sequentially; recording payload information of the versatile audio data storage file into the versatile audio data storage file; and recording index information of VAC frames stored in the versatile audio data storage file into the versatile audio data storage file. A device for storing the audio data is also disclosed, including: a basic information record module, a VAC frame data storage module, a payload information record module and an index information record module. The file generated with this method is simple and is easy to read and access, which can be applied to various applications of the versatile audio frequently.

Abstract: 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.

Abstract: 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.
