Method, apparatus, and system for processing streaming media data

A method for processing streaming media data, comprising:

• receiving an application layer streaming media data block sent by a streaming media server;
• determining a source format and a target format of the application layer streaming media data block, wherein the number of data packets in the application layer streaming media data block is greater than the maximum integral number of data packets that are in the source format and can be contained in one packet in the target format;
• and
• determining a size of each data packet in the application layer streaming media data block according to the source format, and segmenting and encapsulating the data packets in the application layer streaming media data block into at least two packets in the target format according to the size of each data packet and the maximum integral number, wherein each segmented and encapsulated packet in the target format contains the integral number of data packets in the source format.

A streaming media server, comprising:

• a determiner, configured to determine a source format and a target format of application layer streaming media data, wherein,
• the determiner is further configured to determine, according to the source format and the target format, the maximum integral number of data packets that are in the source format and can be contained in one packet in the target format;
• and
• a sender, configured to send an application layer streaming media data block to a streaming media data encapsulation device, wherein the number of data packets in the application layer streaming media data block is greater than the maximum integral number determined by the determiner.

A streaming media data encapsulation device, comprising:

• a receiver, configured to receive an application layer streaming media data block sent by a streaming media server;
• a determiner, configured to determine a source format and a target format of the application layer streaming media data block received by the receiver, wherein the number of data packets in the application layer streaming media data block received by the receiver is greater than the maximum integral number of data packets that are in the source format and can be contained in one packet in the target format, wherein,
• the determiner is further configured to determine a size of each data packet according to the source format;
• and
• a segmentation encapsulator, configured to segment and encapsulate the data packets in the application layer streaming media data block received by the receiver into at least two packets in the target format according to the size of each data packet that is determined by the determiner and the maximum integral number, wherein each segmented and encapsulated packet in the target format contains the integral number of data packets in the source format.
