Title: SYSTEM AND METHOD FOR IMPROVED FINE GRANULAR SCALABLE VIDEO USING BASE LAYER CODING INFORMATION
Abstract:
There is disclosed an apparatus for controlling the transmission of enhancement layer video data for use in a video encoder containing a base layer encoder and an enhancement layer encoder. The base layer encoder receives input video frames and generates compressed base layer video frames suitable for transmission at a base layer bit rate to a streaming video receiver. The enhancement layer encoder compares the input video frames and a processed version of the compressed base layer video frames and generates enhancement layer video data suitable for transmission at a modifiable enhancement layer bit rate to the streaming video receiver. The apparatus comprises a base layer parameter monitor for receiving at least one base layer parameter and, in response thereto, modifying an allocation of the enhancement layer video data among corresponding ones of the compressed base layer video frames.
