FINE GRAIN LOOKAHEAD ENHANCEMENT FOR VIDEO CODING

Abstract:

Techniques related to video coding using look ahead analysis and block based back propagation for block level quantization parameters are discussed. Such techniques include adaptively selecting frames subsequent to a target frame in a display order for use in the back propagation, propagating values to blocks of the target frame that are indicative of the importance of the blocks to the encode of the subsequent frames, and encoding the target frame using block level quantization parameters based on the propagated values.
