Source rate and channel rate matching for scalable video transmission

A system for scalable video coding transmission, comprising:

• a rate matching node to facilitate communication between a user equipment (UE) and a wireless communication network, wherein the rate matching node comprises:
• at least one transmitter to transmit information from the rate matching node;
• at least one receiver to receive information from a video server;
• a processing unit executing computer program instructions to:
• create an enhancement profile associated with scalable video coding transmission, wherein the enhancement profile is a directed graph comprising of a plurality of nodes, wherein each node is associated with a source rate and enhancement options for a video bit stream, wherein the enhancement options include a frame rate and a frame size, wherein an edge between two nodes represents enhancement in the frame rate or the frame size;
• identify a source rate associated with the video bit stream and a channel rate associated with wireless communication environment, wherein the video bit stream is a Scalable Video Codec (SVC) of an H.264/MPEG4 Advanced Video Coding, wherein the channel rate is associated with at least one segment bandwidth rate;
• match the source rate to a node within the enhancement graph to determine Network Abstraction Layer (NAL) units comprising enhancement values based on enhancement options associated with the node, wherein the source rate associated with the node is less than or equal to the available channel rate;
• and
• transmit, via the transmitter, the SVC having the determined NAL units and the enhancement values.
