Video Stream Format Recognition via Intermediary Metadata
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image transmission technologies do not effectively enable the receiving side to easily recognize the high-quality format of encoded image data included in an extended video stream, making it difficult to utilize the corresponding image data according to display capabilities.
Innovation Solution
A transmitting device generates two video streams, a basic and an extended video stream, with the latter including encoded image data of high-quality format, and inserts information indicating the high-quality format into the stream or container, allowing the receiving side to identify and process the data accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If extended video stream includes encoded image data of high-quality format, then image quality is improved, but receiving side cannot easily recognize the high-quality format
Solution Approach 1:
The patent introduces format indication information as an intermediary element that carries metadata about the high-quality format (HDR, HFR, or both) within the extended video stream. This intermediary allows the receiving side to easily recognize and identify the format type without requiring complex analysis of the encoded image data itself, thus resolving the contradiction between maintaining high image quality and enabling easy format recognition.
2Adaptability or versatility
If basic video stream and extended video stream are transmitted separately, then transmission flexibility is improved, but data processing complexity increases
Solution Approach 1:
The patent segments the video transmission into two independent streams: a basic video stream containing standard format image data and an extended video stream containing high-quality format image data. This segmentation allows each stream to be processed and transmitted independently, providing transmission flexibility while the format indication information in the extended stream simplifies the receiving side's processing by clearly identifying which stream contains high-quality data, thus reducing actual processing complexity.
Solution Approach 2:
The patent applies local quality by providing different quality levels in different streams - the basic stream for standard quality requirements and the extended stream for high-quality requirements. The format indication information locally identifies within the extended stream which segments contain HDR, HFR, or both qualities, enabling selective processing only where needed and reducing overall data processing complexity.

AI summary
The present invention enables a receiving side to easily recognize a high-quality format corresponding to encoded image data included in an extended video stream. Two video streams including a basic video stream including encoded image data of basic format image data, and an extended video stream including encoded image data of high-quality format image data of one type selected from a plurality of types are generated. A container of a predetermined format including the basic video stream and the extended video stream is transmitted. Information indicating a high-quality format corresponding to the encoded image data included in the extended video stream is inserted into the extended video stream and/or the container.
