Gradual Decoding Refresh In Video Coding - A simplified explanation of the abstract
This abstract first appeared for US patent application 18419297 titled 'Gradual Decoding Refresh In Video Coding
Simplified Explanation: The patent application describes a method for decoding a coded video bitstream by a video decoder. The method involves determining the value of a flag from an external input, setting flags accordingly to prevent output of certain pictures, decoding specific pictures, and storing them in a buffer.
- The video decoder checks if a value for a first flag is provided by an external input.
- The first flag is set based on the external input, along with a second flag to prevent output of certain pictures.
- The method involves decoding a specific type of picture known as a Gradual Decoding Refresh (GDR) picture.
- The decoded GDR picture is then stored in a Decoded Picture Buffer (DPB).
Key Features and Innovation:
- External input determines flag values.
- Flags prevent output of specific pictures.
- Decoding and storing of GDR pictures.
Potential Applications: This technology can be used in video decoding systems to efficiently process and store video data.
Problems Solved: This method helps in managing the output of certain types of pictures in a video bitstream, ensuring efficient decoding and storage.
Benefits:
- Improved video decoding efficiency.
- Better management of picture output.
- Enhanced video processing capabilities.
Commercial Applications: Potential commercial applications include video streaming services, surveillance systems, and video editing software.
Prior Art: Prior research in video decoding methods and picture storage techniques may be relevant to this technology.
Frequently Updated Research: Stay updated on advancements in video decoding algorithms and storage technologies for potential improvements in this method.
Questions about Video Decoding: 1. How does this method improve the efficiency of video decoding processes? 2. What are the potential applications of this technology in the video industry?
Original Abstract Submitted
A method of decoding a coded video bitstream implemented by a video decoder is provided. The method includes the video decoder determining whether a value for a first flag is provided by an external input; setting a first flag equal to the value provided by the external input and a second flag equal to the value of the first flag to prevent a gradual decoding refresh (GDR) picture from being output when the value for the first flag is provided by the external input; decoding the GDR picture; and storing the GDR picture in a decoded picture buffer (DPB).
