WEIGHTED PREDICTION BASED ON VECTORIZED ENTROPY CODING

摘要

This disclosure describes methods that control the selection of predictive coding techniques for enhancement layer video blocks based on characteristics of vectorized entropy coding for such enhancement layer video blocks. In accordance with this disclosure, the predictive techniques used for predictive-based video coding of enhancement layer video blocks are dependent upon the vectorized entropy coding used for such enhancement layer the video blocks. For each coded unit, predictive coding techniques (e.g. weighted or non-weighted prediction) may be selected depending upon whether the vectorized entropy coding defines a single vector for the video blocks of that coded unit or multiple vectors for the video blocks of that coded unit.
