IMAGE DECODING METHOD AND APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17915313 titled 'IMAGE DECODING METHOD AND APPARATUS

Simplified Explanation

The abstract describes an image decoding method performed by a decoding apparatus. Here is a simplified explanation of the abstract:

  • The method involves obtaining image information that includes HRD-related information for a specific OLS (Operational Layer Set) from a plurality of layers.
  • The method determines if there is an HRD parameter syntax structure related to the target OLS based on the HRD-related information.
  • If the HRD parameter syntax structure exists, it is derived based on the determination result.
  • A DPB (Decoded Picture Buffer) management process is performed for the target OLS based on the HRD parameter syntax structure.
  • Finally, the current picture is decoded based on the DPB.

Potential applications of this technology:

  • Video streaming services: This image decoding method can be used in video streaming platforms to efficiently decode and display high-quality images.
  • Video surveillance systems: The method can be applied in video surveillance systems to decode and analyze video footage captured by surveillance cameras.
  • Video editing software: This technology can be integrated into video editing software to enhance the decoding process and improve the overall editing experience.

Problems solved by this technology:

  • Efficient decoding: The method allows for efficient decoding of images by managing the Decoded Picture Buffer based on the HRD parameter syntax structure.
  • Improved image quality: By properly managing the DPB, the method ensures that the current picture is decoded accurately, resulting in improved image quality.
  • Compatibility: The method can be applied to different layers of an image, making it compatible with various image formats and codecs.

Benefits of this technology:

  • Enhanced decoding performance: The method optimizes the decoding process by utilizing the HRD parameter syntax structure, leading to improved decoding performance.
  • Improved image display: By managing the DPB effectively, the method ensures that the decoded images are displayed accurately, resulting in a better viewing experience.
  • Flexibility: The method can be applied to different layers of an image, providing flexibility in handling various image formats and codecs.


Original Abstract Submitted

An image decoding method performed by a decoding apparatus according to the present disclosure comprises the steps of: obtaining image information including HRD-related information relating to a target OLS, wherein the target OLS is one of OLSs including a plurality of layers; determining whether an HRD parameter syntax structure relating to the target OLS exists, on the basis of the HRD-related information; deriving an HRD parameter syntax structure relating to the target OLS on the basis of a result of the determination; performing a DPB management process relating to a DPB on the basis of the HRD parameter syntax structure for the target OLS; and decoding a current picture on the basis of the DPB.
