Abstract:
Methods and apparatuses are provided for achieving improved video coding efficiency through the use of Motion Vector Predictors (MVPs) for the encoding or decoding of motion parameters within the calculation of the motion information in B pictures and/or P pictures. Certain exemplary methods and apparatuses selectively apply temporal and/or spatial prediction. Rate Distortion Optimization (RDO) techniques are also applied in certain methods and apparatuses to further help improve coding efficiency.
