Adaptation Parameter Set Types in Video Coding - A simplified explanation of the abstract
This abstract first appeared for US patent application 18544105 titled 'Adaptation Parameter Set Types in Video Coding
The patent application describes a video coding mechanism that involves receiving a bitstream with various adaptation parameter sets (APS) and decoding a slice using these parameters for display in a decoded video sequence.
- The mechanism includes adaptive loop filter (ALF) parameters from the first APS NAL unit, scaling list parameters from the second APS NAL unit, and luma mapping with chroma scaling (LMCS) parameters from the third APS NAL unit.
- These parameters are used to decode the slice efficiently and accurately.
- The innovation allows for improved video quality and compression efficiency by utilizing different parameter sets for various aspects of the video coding process.
- By decoding the slice with the obtained parameters, the mechanism ensures a high-quality display of the video content.

Original Abstract Submitted
A video coding mechanism is disclosed. The mechanism includes receiving a bitstream comprising a first adaptation parameter set (APS) network abstraction layer (NAL) unit including an adaptive loop filter (ALF) type, a second APS NAL unit including a scaling list type, a third APS NAL unit including a luma mapping with chroma scaling (LMCS) type, and a slice. The mechanism further includes obtaining ALF parameters from the first APS NAL unit, obtaining scaling list parameters from the second APS NAL unit, and LMCS parameters from the third APS NAL unit. The mechanism further includes decoding the slice using the ALF parameters, the scaling list parameters, and the LMCS parameter. The mechanism further includes forwarding the slice for display as part of a decoded video sequence.
