REFERENCE PICTURE RESAMPLING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18747861 titled 'REFERENCE PICTURE RESAMPLING
Simplified Explanation: The patent application describes methods and apparatus for video encoding and decoding, specifically focusing on the conversion between a current picture of a video and its bitstream according to a specified rule.
Key Features and Innovation:
- Conversion between current picture and bitstream based on a rule.
- Rule specifies conditions for the reference picture list of the current picture.
- Allows for slices in the current picture to have slice types other than Intra (I) slice type.
- Presence of reference picture list (RPL) information in the picture header.
Potential Applications: This technology can be applied in various video encoding and decoding systems, such as video streaming services, video conferencing platforms, and multimedia content delivery networks.
Problems Solved: This technology addresses the need for efficient and accurate video encoding and decoding processes, ensuring high-quality video playback and transmission.
Benefits:
- Improved video quality and compression efficiency.
- Enhanced video streaming performance.
- Better utilization of reference picture lists for encoding and decoding.
Commercial Applications: The technology can be utilized in the development of video encoding and decoding software, hardware, and systems for commercial use in industries such as entertainment, communication, and broadcasting.
Prior Art: Readers can explore prior art related to video encoding and decoding methods, reference picture lists, and slice types in video compression standards such as H.264 (ITU-T H.264) and H.265 (ITU-T H.265).
Frequently Updated Research: Researchers may find updated studies on video compression techniques, reference picture list optimization, and slice type configurations in modern video encoding and decoding technologies.
Questions about Video Encoding and Decoding: 1. What are the key factors influencing the efficiency of video encoding and decoding processes? 2. How does the presence of reference picture list information impact the quality of video compression and transmission?
Original Abstract Submitted
Examples of video encoding methods and apparatus and video decoding methods and apparatus are described. An example method of video processing includes performing a conversion between a current picture of a video and a bitstream of the video according to a rule. The rule specifies that a number of entries in a reference picture list of the current picture is greater than 0 in response to (1) one or more slices in the current picture being allowed to have a slice type other than an Intra (I) slice type, and (2) reference picture list (RPL) information being present in a picture header.
