IP3 2023 – Video Codec 5 (LOT 14301)

This lot is generally related to a technique of scalable video coding to improve coding efficiency. Disclosed is a technique of a scalable video encoding by determining whether a block of a base layer of a current frame to be encoded and overrides a previous weight value set for a block of an enhancement layer of a reference frame with a new weight value. The system generates a reference block for the current frame based on the block of the enhancement layer and the block of the base layer of the current frame using the new weight value. The technology may be implemented in real-time video-streaming systems, live video conferencing, surveillance systems, etc.
