Method and apparatus for distributing video packets over multiple bearers for providing unequal packet loss protection
摘要:
A method and apparatus distributes video packets over multiple bearers for providing unequal packet loss protection. The method includes receiving a plurality of packets that collectively includes video data from a group of pictures comprising a sequence of video frames, wherein the sequence includes one Intra frame at the beginning of the group of pictures followed by a plurality of Predictive frames. For each packet, the packet processing function: determines the corresponding frame that includes the video data; applies a bearer selection process to select one of multiple bearers for transporting the packet over an access network, wherein each bearer has a different quality of service level which influences the probability of the transported packets being dropped, wherein the bearer selection process is based on the position of the frame within the sequence of frames; and provides, to an access network entity, an indication of the selected bearer.
