==INCREMENTAL TRANSFORM SET CONSTRUCTION AND TRANSFORM SIGNALING FOR VIDEO CODING - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18358111 titled 'INCREMENTAL TRANSFORM SET CONSTRUCTION AND TRANSFORM SIGNALING FOR VIDEO CODING

==Simplified Explanation==

The abstract of this patent application describes a system for coding and decoding video content using adaptive transform coding. The system uses a hierarchy of transform sets, where each set includes a number of transforms and higher-level sets include the transforms of lower-level sets. The system allows video coders and decoders to exchange signaling to establish a context for selecting and using the appropriate transform set for coding and decoding blocks of video content.

* The system performs transform coding and decoding on blocks of video content.
* Transform types are organized into a hierarchy of transform sets.
* Each transform set includes a respective number of transforms.
* Higher-level transform sets include the transforms of lower-level sets.
* Video coders and decoders exchange signaling to establish a transform set context.
* The context helps identify the transform set selected for coding a given block(s).
* Video coders and decoders also exchange signaling to establish a transform decoding context.
* The context helps identify the transform selected from the identified transform set for decoding the transform unit.
* The selected transform is used to code and decode the block(s).

Potential applications of this technology:

* Video compression and encoding systems
* Video streaming services
* Video conferencing and telecommunication systems
* Video surveillance and security systems

Problems solved by this technology:

* Efficient coding and decoding of video content
* Reduction in bandwidth and storage requirements for video transmission and storage
* Improved video quality and compression efficiency
* Adaptive selection of transform types based on the characteristics of video content

Benefits of this technology:

* Higher compression ratios for video content
* Reduced bandwidth and storage costs
* Improved video streaming and playback performance
* Enhanced video quality and visual experience


==Original Abstract Submitted==

Video coders and decoders perform transform coding and decoding on blocks of video content according to an adaptively selected transform type. The transform types are organized into a hierarchy of transform sets where each transform set includes a respective number of transforms and each higher-level transform set includes the transforms of each lower-level transform set within the hierarchy. The video coders and video decoders may exchange signaling that establishes a transform set context from which a transform set that was selected for coding given block(s) may be identified. The video coders and video decoders may exchange signaling that establishes a transform decoding context from which a transform that was selected from the identified transform set to be used for decoding the transform unit. The block(s) may be coded and decoded by the selected transform.
