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 18419243 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 a current picture.
- The method involves receiving a coded video bitstream containing a GDR picture and a flag.
- Setting the value of a flag based on the value of another flag.
- Emptying previously-decoded pictures from a buffer based on the flag value.
- Decoding a current picture after the buffer has been emptied.
Key Features and Innovation: - The method involves efficiently managing decoded pictures in a video decoding process. - The use of flags helps in determining when to empty the buffer for optimal decoding. - The inclusion of a GDR picture enhances the decoding process by providing gradual refresh.
Potential Applications: This technology can be applied in video decoding systems, streaming services, video conferencing platforms, and multimedia applications.
Problems Solved: - Efficient management of decoded pictures in a video decoding process. - Optimizing the decoding process based on the presence of a GDR picture. - Ensuring smooth and continuous video playback by decoding pictures in the correct order.
Benefits: - Improved video decoding efficiency. - Enhanced video quality with gradual refresh. - Seamless video playback experience for users.
Commercial Applications: The technology can be utilized in video streaming services, video conferencing platforms, multimedia applications, and any system that involves video decoding processes.
Prior Art: Prior research in video decoding techniques, buffer management in video processing, and gradual refresh mechanisms in video encoding may provide insights into related technologies.
Frequently Updated Research: Stay updated on advancements in video coding standards, buffer management algorithms, and video processing techniques to enhance the efficiency of video decoding processes.
Questions about video decoding technology: 1. How does the method of setting flag values impact the efficiency of video decoding? 2. What are the potential challenges in implementing this technology in real-time video applications?
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.
