AI Technical Summary
Technical Problem
Existing video coding technologies face challenges in efficiently compressing and decompressing video data, particularly in reducing redundant coding of parameters like LMCS, which can lead to increased network, memory, and processing resource usage.
Method used
The implementation of an LMCS adaptation parameter set (APS) that includes LMCS parameters associated with a coded slice, allowing these parameters to be encoded only when they change, thereby reducing redundant coding and enhancing coding efficiency.
Benefits of technology
This approach significantly reduces redundant coding of LMCS parameters by a factor of thirty to sixty, leading to increased coding efficiency and reduced resource usage at both the encoder and decoder.
