摘要：
A source rate associated with a video bit stream (112) and a channel (140) rate associated with an LTE environment can be identified. The video bit stream (112) can be a Scalable Video Codec (SVC) of an H.264/MPEG4 Advanced Video Coding. The channel (140) rate can be associated with one or more segment bandwidth (142) rates. An enhancement path from an enhancement profile (332) associated with the SVC can be determined. The enhancement profile (332) can include one or more cumulative source rates and an associated enhancement options. The enhancement options can be a frame quantity, frame size, and a frame quality (122, 124, 126). The enhancement path can be a subset of nodes of the enhancement graph (400). The channel (140) rate can be matched to a cumulative source rate to a node within the enhancement path. One or more Network Abstraction Layer (NAL) units (144) with the appropriate enhancement values can be conveyed.
