摘要： Parametric Motion Vector Prediction (PMVP) methodologies and components and systems for performing those methodologies are provided to more effectively and efficiently encode video content that includes complex motion such as zoom or rotation. By substituting the PMVP for a collocated MVP used in HEVC in order to reduce the amount of bit rate increase required when including the PMVP analysis in the bit stream. Further, compression of the motion vectors is provided in a three stage approach based on transformation, quantization and difference coding.
