Output of Prior Pictures for Pictures Starting a New Coded Video Sequence In Video Coding - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240305808 titled 'Output of Prior Pictures for Pictures Starting a New Coded Video Sequence In Video Coding
Simplified Explanation: The patent application describes a method for decoding a coded video bitstream that includes a gradual decoding refresh (GDR) picture and a flag. The method involves setting a flag value, emptying previously-decoded pictures from a buffer, and decoding the current picture.
- The method involves receiving a coded video bitstream containing a GDR picture and a flag.
- Setting the value of a flag to determine the decoding process.
- Emptying any previously-decoded pictures from a buffer based on the flag value.
- Decoding the current picture after the buffer has been emptied.
Key Features and Innovation:
- Utilizes a gradual decoding refresh (GDR) picture in the coded video bitstream.
- Implements a flag to control the decoding process.
- Efficiently manages previously-decoded pictures in a buffer.
- Facilitates the decoding of the current picture after buffer management.
Potential Applications: This technology can be applied in:
- Video streaming services.
- Video surveillance systems.
- Video conferencing platforms.
- Multimedia content delivery networks.
Problems Solved:
- Efficient management of decoded pictures in a buffer.
- Seamless decoding of video bitstreams with GDR pictures.
- Optimization of the decoding process for video content.
Benefits:
- Improved decoding efficiency.
- Enhanced video quality.
- Reduced processing delays.
- Better utilization of system resources.
Commercial Applications: Title: Enhanced Video Decoding Method for Improved Efficiency This technology can be utilized in various commercial applications such as:
- Video streaming platforms.
- Security and surveillance systems.
- Telecommunication networks.
- Entertainment industry for video production and distribution.
Prior Art: Readers can explore prior art related to video decoding methods, buffer management in video processing, and techniques for optimizing video streaming performance.

Questions about Video Decoding: 1. What are the key components of a coded video bitstream? 2. How does the flag value impact the decoding process in this method?
Original Abstract Submitted
a method of decoding a coded video bitstream is provided. the method includes receiving the coded video bitstream, wherein the coded video bitstream contains a gradual decoding refresh (gdr) picture and a first flag having a first value; setting a second value of a second flag equal to the first value of the first flag; emptying any previously-decoded pictures from a decoded picture buffer (dpb) based on the second flag having the second value; and decoding a current picture after the dpb has been emptied. a corresponding method of encoding is also provided.
