IMAGE ENCODING/DECODING METHOD AND DEVICE FOR SIGNALING INFORMATION RELATING TO PTL, DPB, AND HRD IN SPS, AND COMPUTER-READABLE RECORDING MEDIUM STORING BITSTREAM - A simplified explanation of the abstract
This abstract first appeared for US patent application 17916188 titled 'IMAGE ENCODING/DECODING METHOD AND DEVICE FOR SIGNALING INFORMATION RELATING TO PTL, DPB, AND HRD IN SPS, AND COMPUTER-READABLE RECORDING MEDIUM STORING BITSTREAM
Simplified Explanation
The patent application describes a method and apparatus for encoding and decoding images, specifically for signaling profile tier level (PTL), decoded picture buffer (DPB), and hypothetical reference decoder (HRD) related information in a sequence parameter set (SPS). It also includes a method for transmitting a bitstream.
- The method involves obtaining flag information that indicates the presence of PTL, DPB, and HRD related information in the SPS.
- Based on the flag information, at least one of the PTL syntax structure, DPB parameter syntax structure, and HRD parameter syntax structure is obtained.
- The current output layer set (OLS) is processed based on the obtained syntax structure.
- The flag information has a predetermined value when an OLS with only one layer, having the same layer identifier as the SPS, is present.
Potential applications of this technology:
- Video encoding and decoding systems
- Multimedia streaming services
- Video conferencing and telecommunication systems
Problems solved by this technology:
- Efficient signaling of PTL, DPB, and HRD related information in image encoding and decoding processes
- Simplified syntax structure for sequence parameter sets
- Improved processing of current output layer sets
Benefits of this technology:
- Enhanced video quality and compression efficiency
- Reduced complexity in image encoding and decoding algorithms
- Improved compatibility and interoperability between different video encoding and decoding systems
Original Abstract Submitted
An image encoding/decoding method and apparatus for signaling PTL, DPB and HRD related information in SPS and a method of transmitting a bitstream are provided. The image decoding method may comprise obtaining flag information indicating whether a profile tier level (PTL) syntax structure, a decoded picture buffer (DPB) parameter syntax structure and a hypothetical reference decoder (HRD) parameter syntax structure are present in a sequence parameter set (SPS), obtaining at least one among the PTL syntax structure, DPB parameter syntax structure and HRD parameter syntax structure, based on the flag information, and processing a current output layer set (OLS), based on the obtained syntax structure. The flag information may have a predetermined value, based on that an OLS including only one layer having the same layer identifier as a layer identifier of the SPS is present.
