IMAGE ENCODING/DECODING METHOD AND DEVICE FOR SIGNALING DPB-RELATED INFORMATION AND PTL-RELATED INFORMATION, AND COMPUTER-READABLE RECORDING MEDIUM IN WHICH BITSTREAM IS STORED - A simplified explanation of the abstract
This abstract first appeared for US patent application 17916371 titled 'IMAGE ENCODING/DECODING METHOD AND DEVICE FOR SIGNALING DPB-RELATED INFORMATION AND PTL-RELATED INFORMATION, AND COMPUTER-READABLE RECORDING MEDIUM IN WHICH BITSTREAM IS STORED
Simplified Explanation
The patent application describes a method and apparatus for encoding and decoding images, specifically related to signaling information about the decoded picture buffer (DPB) and profile tier level (PTL) in a video parameter set (VPS). The method also includes transmitting a bitstream.
- The method involves obtaining information about the number of DPB parameter syntax structures in the VPS.
- Based on this information, the one or more DPB parameter syntax structures are obtained from the VPS.
- Second information is obtained, which relates to the relationship between multi-layer output layer sets (OLSs) and the DPB parameter syntax structures.
- A DPB parameter syntax structure is selected based on the second information, which applies to the current OLS.
- The current OLS is then processed using the selected DPB parameter syntax structure.
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 DPB and PTL information in video encoding and decoding processes
- Simplified management of DPB parameter syntax structures in relation to multi-layer output layer sets
Benefits of this technology:
- Improved video encoding and decoding efficiency
- Enhanced video quality and performance
- Simplified configuration and management of video parameters
Original Abstract Submitted
An image encoding/decoding method and apparatus for signaling decoded picture buffer (DPB) related information and profile tier level (PTL) related information and a method of transmitting a bitstream are provided. The image decoding method according to the present disclosure may comprise obtaining first information indicating the number of one or more decoded picture buffer (DPB) parameter syntax structures in a video parameter set (VPS), obtaining the one or more DPB parameter syntax structures from the VPS based on the first information, obtaining second information between one or more multi-layer output layer sets (OLSs) and the one or more DPB parameter syntax structures from the VPS based on the first information, selecting a DPB parameter syntax structure that applies to a current OLS based on the second information, and processing the current OLS based on the selected DPB parameter syntax structure.
