Regional Nesting SEI Messages for Video Bitstream Metadata
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video coding techniques face inefficiencies in compressing large digital video data while maintaining high quality, leading to increased storage and transmission burdens, and existing SEI messages require redundant signaling of region-specific metadata, which is inefficient and lacks a common framework for region-based applications.
Innovation Solution
The introduction of regional nesting messages, which include region data defining multiple regions of a picture and nested SEI messages with region identifiers, allowing for efficient signaling of metadata applicable to specific regions, reducing redundancy and enabling region-based processing without redefining SEI messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional SEI messages are used for region-specific metadata, then region-specific processing can be supported, but redundant signaling occurs and coding efficiency deteriorates
Solution Approach 1:
The patent combines multiple SEI messages containing region data into a single regional nesting SEI message. Instead of transmitting separate SEI messages for each region, the invention merges them into one container message that holds multiple nested messages, each associated with specific regions through region identifiers. This merging eliminates redundant signaling and improves coding efficiency while maintaining support for region-specific processing.
Solution Approach 2:
The regional nesting SEI message serves multiple functions: it acts as a container for multiple nested SEI messages, provides region identification through region identifiers, and enables region-specific metadata association. This multi-functional design allows a single message structure to replace multiple traditional SEI messages, reducing redundancy while maintaining versatility for various region-based applications.
2Adaptability or versatility
If multiple separate SEI messages are transmitted for different regions, then complete region coverage is achieved, but data volume and transmission burden increase
Solution Approach 1:
The patent merges multiple separate SEI messages into a single regional nesting SEI message that contains multiple nested messages. Each nested message is associated with specific regions through region identifiers, ensuring complete region coverage. By combining these messages into one container, the patent reduces the overall data volume and transmission burden while maintaining the ability to address all necessary regions.
Solution Approach 2:
The invention implements a nested structure where multiple SEI messages are placed inside a single regional nesting SEI message container. This nesting approach allows the outer message to serve as a parent container holding multiple child nested messages, each with its own region-specific data. The nested structure reduces redundant signaling overhead and compresses the total data volume while preserving complete region coverage through the nested messages.

AI summary
Systems, methods, and computer readable media are described for generating a regional nesting message. In some examples, a video bitstream is obtained and an encoded video bitstream is generated using the video data. The encoded video bitstream includes a regional nesting message that contains a plurality of nested messages and region data defining at least a first region of a picture of the encoded video bitstream. For example, a first nested message of the regional nesting message includes a first set of data and a first region identifier indicating the first region of the picture is associated with the first set of data.
