System, Components and Method for Parametric Motion Vector Prediction for Hybrid Video Coding

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention introduces a system and methods for improving motion vector prediction in video compression, specifically for complex motion types like zooming or rotation. The proposed Parametric Motion Vector Prediction (PMVP) replaces conventional prediction techniques in hybrid video coding (such as HEVC), aiming to reduce required bitrate and enhance coding efficiency. The process uses a three-stage approach involving transformation, quantization, and difference coding for compressing motion vectors.

Patent Abstract

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.
