Abstract

Multi-level prediction mode encoding type decision methods and systems are presented. In one embodiment, an indication of a prediction mode level is received and encoding is performed in accordance with said prediction mode level. The indication of said prediction mode level is programmable and can be set at different levels. The prediction mode level can be associated with a programmable encoding type decision point (e.g., early, intermediate, late, etc.). The encoding process includes deciding upon an I-type or P-type encoding. In one embodiment, a multi-stage encoding type method is also implemented in intra-prediction related search and inter-prediction related search and respective corresponding prediction operations are performed, wherein at least a portion of the intra-prediction related search and the inter-prediction related search are performed in parallel.
