IMAGE ENCODING/DECODING METHOD AND DEVICE FOR SIGNALING HRD PARAMETERS, AND COMPUTER-READABLE RECORDING MEDIUM IN WHICH BITSTREAM IS STORED - A simplified explanation of the abstract

This abstract first appeared for US patent application 17915235 titled 'IMAGE ENCODING/DECODING METHOD AND DEVICE FOR SIGNALING HRD PARAMETERS, AND COMPUTER-READABLE RECORDING MEDIUM IN WHICH BITSTREAM IS STORED

Simplified Explanation

The patent application describes an image encoding/decoding method and apparatus for signaling hypothetical reference decoder (HRD) related parameters, as well as a method of transmitting a bitstream.

  • The method involves obtaining information about the number of HRD parameter syntax structures in a video parameter set (VPS).
  • The HRD parameter syntax structures are then obtained from the VPS based on the obtained information.
  • The method also includes obtaining information on the mapping between multi-layer output layer sets (OLSs) and the HRD parameter syntax structures from the VPS.
  • A HRD parameter syntax structure that applies to the current OLS is selected based on the obtained mapping information.
  • The current OLS is then processed based on the selected HRD parameter syntax structure.

Potential applications of this technology:

  • Video encoding and decoding systems
  • Video streaming services
  • Video surveillance systems
  • Video conferencing systems

Problems solved by this technology:

  • Efficient signaling of HRD related parameters in image encoding/decoding
  • Simplified mapping between OLSs and HRD parameter syntax structures
  • Improved processing of OLSs based on selected HRD parameter syntax structure

Benefits of this technology:

  • Improved video quality and compression efficiency
  • Enhanced compatibility between different video encoding/decoding systems
  • Simplified implementation of HRD related parameters in video transmission


Original Abstract Submitted

Disclosed herein are an image encoding/decoding method and apparatus for signaling hypothetical reference decoder (HRD) related parameters, and a method of transmitting a bitstream. An image decoding method may comprise obtaining first information specifying the number of one or more hypothetical reference decoder (HRD) parameter syntax structures in a video parameter set (VPS), obtaining the one or more HRD parameter syntax structures from the VPS based on the first information, obtaining second information on mapping between one or more multi-layer output layer sets (OLSs) and the one or more HRD parameter syntax structures from the VPS based on the first information, selecting a HRD parameter syntax structure that applies to a current OLS based on the second information, and processing the current OLS based on the selected HRD parameter syntax structure.
