Sub-Picture Based Random Access - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240187610 titled 'Sub-Picture Based Random Access
Simplified Explanation
The abstract describes a method for decoding a coded video bitstream implemented by a video decoder. The method involves receiving a mixed intra random access point (IRAP) picture with two sub-pictures, decoding the second sub-picture using a reference picture list (RPL), and generating an image based on the decoded second sub-picture.
- Receiver receives a mixed IRAP picture with an IRAP sub-picture and a non-IRAP sub-picture.
- Receiver obtains a reference picture list (RPL) for the mixed IRAP picture.
- Processor decodes the second sub-picture using the RPL.
- Processor generates an image based on the decoded second sub-picture.
Potential Applications: - Video decoding technology - Multimedia applications - Video streaming services
Problems Solved: - Efficient decoding of mixed IRAP pictures - Improved video quality - Enhanced multimedia experiences
Benefits: - Higher quality video decoding - Better utilization of reference pictures - Enhanced user experience
Potential Commercial Applications: - Video streaming platforms - Multimedia software development - Video compression technology
Possible Prior Art: - Existing video decoding methods - Multimedia processing techniques
Questions: 1. How does this method compare to existing video decoding techniques? 2. What impact does the use of mixed IRAP pictures have on video quality and decoding efficiency?
Frequently Updated Research: - Research on video compression algorithms - Studies on multimedia processing techniques
Original Abstract Submitted
a method of decoding a coded video bitstream implemented by a video decoder is provided. the method includes receiving, by a receiver of the video decoder, a mixed intra random access point (irap) picture including a first sub-picture and a second sub-picture, wherein the first sub-picture is an irap picture and the second sub-picture is a non-irap sub-picture; receiving, by the receiver; a reference picture list (rpl) for the mixed irap picture; decoding, by a processor of the video decoder, the second sub-picture using the rpl; and generating, by the processor, an image based on the second sub-picture as decoded. a corresponding encoding method is also provided.
