IMAGE PROCESSING METHOD, AND DEVICE FOR SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240121393 titled 'IMAGE PROCESSING METHOD, AND DEVICE FOR SAME
Simplified Explanation
The present invention relates to a method for encoding/decoding a video signal and an apparatus for the method. Specifically, the method for decoding a video signal involves generating a residual block of a current block, parsing a transform skip flag, determining whether to parse a primary transform flag, parsing the primary transform flag if necessary, and generating a primary inverse transformed transform block of the current block.
- Generating a residual block of a current block by performing entropy decoding on the video signal
- Parsing a transform skip flag to determine if a transform skip is applied to the current block
- Determining whether to parse a primary transform flag to indicate if a primary transform is applied
- Parsing the primary transform flag if necessary
- Generating a primary inverse transformed transform block of the current block by performing a primary inverse transform to the residual block

Possible Prior Art
One possible prior art could be the H.264 video compression standard, which also involves various encoding and decoding techniques for video signals.
=== What are the specific steps involved in generating a primary inverse transformed transform block of the current block? To generate a primary inverse transformed transform block of the current block, the method involves performing a primary inverse transform to the residual block after parsing the primary transform flag.
=== How does the size of the current block affect the parsing of the transform skip flag in the method? If the size of the current block is smaller than a predetermined first size, the method parses a transform skip flag to determine whether a transform skip is applied to the current block.
Original Abstract Submitted
the present invention discloses a method for encoding/decoding a video signal and an apparatus for the method. more specifically, a method for decoding a video signal comprises generating a residual block of a current block by performing entropy decoding on the video signal; if size of the current block is smaller than a predetermined first size, parsing a transform skip flag which indicates whether a transform skip is applied to the current block; determining whether to parse a primary transform flag which indicates whether a primary transform is applied to the current block; if it is determined to parse the primary transform flag, parsing the primary transform flag; and if the primary transform flag indicates that a primary transform is applied to the current block, generating a primary inverse transformed transform block of the current block by performing a primary inverse transform to the residual block.
