==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.
