Reference Picture Management in Video Coding - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240259553 titled 'Reference Picture Management in Video Coding
The abstract describes a method for decoding a coded video bitstream by marking the status of reference pictures in a decoded picture buffer based on reference picture lists and using them in the reconstructing process of the current or following pictures.
- Obtaining first and second reference picture lists for a current slice in a coded video bitstream
- Marking the status of reference pictures in a decoded picture buffer for short-term or long-term reference, or unused for reference
- Using the reference pictures in the reconstructing process of the current or following pictures when marked for short-term or long-term reference
Potential Applications: - Video decoding technology - Multimedia applications - Video streaming services
Problems Solved: - Efficient decoding of video bitstreams - Proper utilization of reference pictures for reconstructing video frames
Benefits: - Improved video quality - Reduced decoding complexity - Enhanced video streaming experience
Commercial Applications: Title: Advanced Video Decoding Technology for Enhanced Multimedia Applications This technology can be used in video streaming services, multimedia applications, and video playback devices to improve video quality and decoding efficiency.
Prior Art: Researchers can explore existing patents related to video decoding methods and reference picture management in video processing technologies.

Questions about Video Decoding Technology: 1. How does this method improve the decoding process of video bitstreams? 2. What are the key benefits of marking reference pictures in a decoded picture buffer for short-term or long-term reference?
Original Abstract Submitted
a method of decoding a coded video bitstream. the method includes obtaining a first reference picture list of a current slice represented in the coded video bitstream and a second reference picture list of the current slice, and marking a status of a reference picture in a decoded picture buffer (dpb) based on the first reference picture list and the second reference picture list when the current slice is a first slice in a current picture to which the current slice belongs. the status of the reference picture in the decoded picture buffer is used for short-term reference, used for long-term reference, or unused for reference. the method also includes using the reference picture in a reconstructing process of the current picture or a picture following the current picture when the status of the reference picture is used for short-term reference or used for long-term reference.
