ALLOWING A MATRIX BASED INTRA PREDICTION BLOCK TO HAVE MULTIPLE TRANSFORM BLOCKS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240340454 titled 'ALLOWING A MATRIX BASED INTRA PREDICTION BLOCK TO HAVE MULTIPLE TRANSFORM BLOCKS
Simplified Explanation:
The patent application describes a method, decoder, and apparatus that determine the decoding process for a current block based on whether it is a MIP predicted block with one or multiple transform blocks. The MIP weight matrix is used to decode the block, and the decoding process varies depending on the number of transform blocks present.
- The method determines if the current block is a MIP predicted block with one or multiple transform blocks.
- Based on the MIP prediction mode, a MIP weight matrix is selected for decoding.
- If the MIP predicted block has one transform block, it is derived using the MIP weight matrix and previously decoded elements.
- If the MIP predicted block has multiple transform blocks, the first block is derived using the MIP weight matrix and previously decoded elements, while the remaining blocks are derived based on decoded elements in at least one decoded transform block of the current block.
- The MIP predicted blocks are output for further processing.
Potential Applications: This technology can be applied in video coding, image processing, and data compression systems where efficient decoding of blocks with multiple transform blocks is required.
Problems Solved: This technology addresses the challenge of efficiently decoding MIP predicted blocks with varying numbers of transform blocks, improving overall decoding performance.
Benefits: - Enhanced decoding efficiency for MIP predicted blocks - Improved compression performance in video and image processing applications - Simplified decoding process for blocks with multiple transform blocks
Commercial Applications: Title: Advanced Video Coding Technology for Enhanced Compression This technology can be utilized in video streaming services, surveillance systems, and multimedia applications to improve compression efficiency and reduce bandwidth requirements.
Prior Art: Readers can explore prior research on MIP prediction modes and block decoding techniques in video coding standards like H.264 and H.265.
Frequently Updated Research: Researchers are constantly exploring new algorithms and optimizations for block decoding in video coding standards, which may impact the development of this technology.
Questions about MIP Predicted Block Decoding: 1. How does the MIP weight matrix selection impact the decoding process? 2. What are the implications of efficiently decoding blocks with multiple transform blocks in video compression applications?
Original Abstract Submitted
a method, decoder, and apparatus are provided. responsive to a current block being a mip predicted block, it is determined whether it has one or multiple transform blocks. a mip weight matrix to be used to decode the current block is determined based on a mip prediction mode. responsive to the mip predicted block having one transform block, the mip predicted block is derived based on the mip weight matrix and previously decoded elements in the bitstream. responsive to the mip predicted block having multiple transform blocks: deriving a first mip predicted block is derived based on the mip weight matrix and previously decoded elements in the bitstream and remaining mip predicted blocks are derived based further on decoded elements in at least one decoded transform block of the current block. the mip predicted block(s) are output for subsequent processing.
