METHOD OF DETERMINING TRANSFORM COEFFICIENT SCAN ORDER BASED ON HIGH FREQUENCY ZEROING AND APPARATUS THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 18383327 titled 'METHOD OF DETERMINING TRANSFORM COEFFICIENT SCAN ORDER BASED ON HIGH FREQUENCY ZEROING AND APPARATUS THEREOF
Simplified Explanation
The abstract describes an image decoding method performed by a decoding apparatus, which includes the following steps:
- Receiving a bitstream containing residual information.
- Deriving quantized transform coefficients for a current block based on the residual information in the bitstream.
- Deriving transform coefficients for the current block from the quantized transform coefficients using an inverse quantization process.
- Deriving residual samples for the current block by applying inverse transform to the derived transform coefficients.
- Generating a reconstructed picture based on the residual samples for the current block.
Potential applications of this technology:
- Video streaming services
- Video conferencing systems
- Digital television broadcasting
Problems solved by this technology:
- Efficient compression and transmission of image data
- High-quality image reconstruction
- Reduced bandwidth usage for image transmission
Benefits of this technology:
- Improved image quality
