Video Metadata for Preserving Creative Intent on Target Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies face challenges in preserving the creative intent of video content when displayed on target devices with different characteristics, often requiring manual adjustment of display settings by users, which is time-consuming and not always accurate.
Innovation Solution
The introduction of metadata, specifically the L11 metadata, which communicates the video content's category and intended display settings to the target display, allowing for automatic adjustment and preservation of creative intent, including features like Reference Mode, white point, sharpness, noise reduction, and Frame Rate Conversion, with a hierarchical structure for refined adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment of display settings is used to preserve creative intent, then display accuracy can be improved, but user time consumption and operation complexity increase
Solution Approach 1:
The patent applies preliminary action by embedding display setting parameters and creative intent information into the video bitstream metadata during content creation. This allows the target display to automatically retrieve and apply the correct settings without requiring manual user adjustment, thus preserving display accuracy while eliminating time consumption.
Solution Approach 2:
The system enables self-service by allowing the video content itself to carry the instructions for its optimal display settings. The target display automatically reads the metadata from the bitstream and configures its display parameters accordingly, making the system self-configuring without human intervention.
2Measurement precision
If manual adjustment of display settings is used, then display accuracy can be improved, but operation complexity increases
Solution Approach 1:
The video bitstream with embedded metadata performs self-service by containing all necessary display configuration information. The target display automatically extracts and applies these settings, eliminating the need for complex manual operations by users.
Solution Approach 2:
The metadata in the video bitstream acts as an intermediary that carries display setting instructions from the content creator to the target display. This intermediary structure automates the configuration process, reducing operation complexity while maintaining display accuracy.
3Ease of operation
If automatic display setting adjustment is implemented, then user operation ease is improved, but adaptability to different content types may worsen
Solution Approach 1:
The patent applies local quality by including specific display setting parameters tailored to each content type within the metadata. Different video contents can have different display settings (e.g., brightness, contrast, color temperature) embedded in their respective bitstreams, allowing automatic adaptation to various content types while maintaining ease of operation.
Solution Approach 2:
The system enables parameter changes by allowing display settings to be dynamically adjusted based on the metadata associated with different content types. The target display automatically modifies its operating parameters according to the embedded instructions, achieving both automation and content-specific adaptability.
4Measurement precision
If detailed metadata is embedded in video bitstream, then display setting precision is improved, but data quantity and processing complexity increase
Solution Approach 1:
The patent applies the taking out principle by extracting only the essential display setting parameters needed for creative intent preservation and embedding them in the metadata. This selective extraction avoids unnecessary data bloat while maintaining sufficient precision for accurate display configuration.

AI summary
Apparatus and methods for providing solutions to the problem of preserving original creative intent for video playback on a target display are presented herein. According to one aspect, a video bitstream includes metadata with a flag indicative of creative intent for a target display. This metadata may include numerous fields that denote characteristics such as content type, content sub-type, intended white point, whether or not to use the video in Reference Mode, intended sharpness, intended noise reduction, intended MPEG noise reduction, intended Frame Rate Conversion, intended Average Picture Level, and intended color. This metadata is designed to make it effortless for the content creators to tag their content. The metadata can be added to the video content at multiple points, the status of the flag is set to TRUE or FALSE to indicate whether the metadata was added by the content creator or a third party.
