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 a packet processing function receiving a plurality of packets collectively comprising a flow of sequential data included in a sequence of media frames. For each packet, the packet processing function: applies a bearer selection process to select one of a plurality of 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 intentionally discarded by the access network, wherein the bearer selection process causes distribution of the plurality of packets across the plurality of bearers such that each bearer carries non- consecutive packets both within any given media frame and across sequential media frames and provides unequal packet loss protection for the packets in the plurality; and provides an indication of the selected bearer.
