LIGHT-WEIGHT VIDEO CODING SYSTEM AND DECODER FOR LIGHT-WEIGHT VIDEO CODING SYSTEM

摘要

The disclosure provides a Light-weight Video Coding system and a decoder for a Light-weight Video Coding system. The decoder includes: a mode decision module and a motion estimation module. The mode decision module, which adopts four flexible types of mode decision, is used for selecting a mode. And, it is used for selecting at least one predetermined block of a current frame according to the mode including plurality pixels. The motion estimation module, which adopts the Partial Boundary Matching Algorithm, is used for selecting partial neighbor pixels of left and top of the block according to the predetermined block in the current frame. And it is used for comparing with corresponding neighbor plurality pixels of left and top with a corresponding predetermined block in reference frame. It is determining whether the corresponding predetermined block in the reference frame copies and pastes to the predetermined block in the current frame.
