METHOD, APPARATUS AND SYSTEM FOR ENCODING AND DECODING A TREE OF BLOCKS OF VIDEO SAMPLES - A simplified explanation of the abstract
This abstract first appeared for US patent application 18157479 titled 'METHOD, APPARATUS AND SYSTEM FOR ENCODING AND DECODING A TREE OF BLOCKS OF VIDEO SAMPLES
Simplified Explanation
The patent application describes a method for decoding coding blocks in an image using a coding tree unit. Here are the key points:
- The method involves obtaining the coding tree unit from a bitstream, which includes chroma channels and a luma channel.
- Luma split options for the luma channel are determined based on the dimensions of a region of the coding tree unit.
- Chroma split options for the chroma channels are also determined based on the dimensions of the region, but these options are different from the luma split options.
- The allowable chroma split options ensure that chroma intra predicted blocks have a minimum size of 16 samples.
- The coding blocks are then decoded by selecting one luma split option and one chroma split option based on flags obtained from the bitstream.
Potential applications of this technology:
- Video compression and encoding systems
- Image processing and editing software
- Streaming services and platforms
- Video conferencing and communication tools
Problems solved by this technology:
- Efficient decoding of coding blocks in an image
- Accurate determination of split options for luma and chroma channels
- Ensuring minimum size requirements for chroma intra predicted blocks
Benefits of this technology:
- Improved image and video quality
- Reduced file sizes for storage and transmission
- Faster decoding and processing of images and videos
- Enhanced compression efficiency for better bandwidth utilization
Original Abstract Submitted
A method of decoding coding blocks of a coding tree unit in an image. The method comprises obtaining the coding tree unit in the image from a bitstream, the coding tree unit having chroma channels and a luma channel; and determining luma split options for the luma channel of the coding tree unit according to dimensions of a region of the coding tree unit. The method also comprises determining chroma split options for the chroma channels of the coding tree unit according to dimensions of a region of the coding tree unit, the chroma split options being different to the luma split options, the allowable chroma split options resulting in chroma intra predicted blocks with a minimum size of 16 samples; and decoding the coding blocks by determining flags from the bitstream to select one of the determined luma split options and one of the determined chroma split options.
