IMAGE ENCODING/DECODING METHOD AND APPARATUS BASED ON WRAP-AROUND MOTION COMPENSATION, AND RECORDING MEDIUM STORING BITSTREAM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18418021 titled 'IMAGE ENCODING/DECODING METHOD AND APPARATUS BASED ON WRAP-AROUND MOTION COMPENSATION, AND RECORDING MEDIUM STORING BITSTREAM
Simplified Explanation
The image encoding/decoding method described in the abstract involves obtaining inter prediction information and wraparound information from a bitstream to generate a prediction block for a current block in a video sequence.
- The method includes obtaining inter prediction information and wraparound information from a bitstream.
- The prediction block is generated based on the inter prediction information and wraparound information.
- The wraparound information may include a flag indicating whether wraparound motion compensation is enabled for the current video sequence.
- The flag can specify whether wraparound motion compensation is disabled, based on the presence of independently coded subpictures with different widths in the video sequence.
Potential Applications
This technology can be applied in video encoding and decoding systems, particularly in the field of multimedia compression and transmission.
Problems Solved
1. Efficient encoding and decoding of video sequences with wraparound motion compensation. 2. Handling independently coded subpictures with different widths in a video sequence.
Benefits
1. Improved video compression efficiency. 2. Enhanced video quality with wraparound motion compensation. 3. Better handling of subpictures with different widths in video sequences.
Potential Commercial Applications
1. Video streaming services. 2. Video conferencing systems. 3. Broadcast television.
Possible Prior Art
One possible prior art in this field is the use of motion compensation techniques in video encoding and decoding to improve compression efficiency and video quality.
Unanswered Questions
How does the method handle wraparound information for subpictures with different heights?
The abstract only mentions subpictures with different widths, but it is unclear how the method deals with subpictures of varying heights.
What is the impact of enabling/disabling wraparound motion compensation on video quality?
While the abstract mentions the flag for enabling/disabling wraparound motion compensation, it does not discuss the potential impact on video quality or compression efficiency.
Original Abstract Submitted
An image encoding/decoding method and apparatus are provided. An image decoding method includes obtaining inter prediction information of a current block and wraparound information from a bitstream, and generating a prediction block of the current block based on the inter prediction information and the wraparound information. The wraparound information may include a first flag specifying whether wraparound motion compensation is enabled for a current video sequence including the current block. The first flag may have a first value specifying that the wraparound motion compensation is disabled, based on that one or more subpicture, which is coded independently and has a width different from a width of a current picture, is present in the current video sequence.
