If traditional video coding technologies (MPEG-2, MPEG-4, H.263, H.264, HEVC) are used, then video compression is achieved, but coding efficiency is insufficient
Solution Approach 1:
The patent applies dynamics by making the weighting parameters adaptive rather than fixed. The derivation of weighting parameters is dynamically adjusted based on video characteristics and coding conditions, allowing the system to optimize coding efficiency for different video content types and scenarios, thereby resolving the contradiction between coding efficiency and performance reliability
Solution Approach 2:
The patent changes parameters by introducing adaptive weighting parameters that can be derived and adjusted during the coding process. These parameters modify the prediction and reconstruction operations to optimize coding efficiency for specific video units, transforming the static coding parameters of traditional technologies into dynamic, content-adaptive parameters
