Video Delivery Metadata for Creative Intent Preservation

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional video delivery pipelines fail to accurately preserve the creative intent of video creators due to variations in display characteristics and lack of consideration for prior processing stages, leading to discrepancies in color and brightness between the intended and rendered images.

Innovation Solution

Incorporating metadata into the video data stream that includes characteristics of the reference display, editing environment, and viewing environment, which is embedded and decoded to adjust video processing and display configuration, ensuring that the video is rendered as intended by the creator.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If video data is delivered through conventional video delivery pipeline with high bit depth, then image quality is improved, but display variations still cause color and brightness discrepancies from creative intent

Engineering Contradiction:

Improveimage qualityVSAvoidcolor and brightness accuracy

Core Design Contradiction:

Measurement precisionVSManufacturing precision

Solution Approach 1:

The patent applies preliminary action by embedding metadata about the reference display characteristics and creative intent parameters into the video data stream before delivery. This allows downstream processing stages to pre-configure display settings and processing parameters to match the creator's intent, preventing color and brightness discrepancies before they occur rather than correcting them after display variations manifest.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback by including metadata that describes the reference display characteristics and processing conditions used during creation. This metadata provides information about the original display environment and processing parameters, enabling downstream systems to adjust their processing and display settings to match the intended appearance, creating a feedback loop that preserves creative intent across different delivery stages.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If post-production editing is performed on reference display, then creative intent is established, but downstream display subsystems cannot reproduce the same appearance due to display characteristic variations

Engineering Contradiction:

Improvecreative intent preservationVSAvoiddisplay appearance consistency

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent uses metadata as an intermediary that carries information about the reference display characteristics and creative intent from the post-production stage to downstream display subsystems. This metadata acts as a mediator that translates the creative intent established on the reference display into instructions that guide downstream processing and display configuration, enabling consistent reproduction across different display hardware.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent applies parameter changes by encoding display characteristic parameters and processing parameters into metadata that travels with the video data. Downstream systems use this metadata to adjust their processing parameters and display settings to match the reference display conditions, dynamically changing parameters to maintain appearance consistency despite hardware differences.

Inventive Principle:

Principle #35Parameter changes

3Device complexity

If processing and display methods are performed without knowledge of prior processing stages, then system complexity is reduced, but creative intent cannot be preserved

Engineering Contradiction:

Improveprocessing coordinationVSAvoidcreative intent preservation

Core Design Contradiction:

Device complexityVSManufacturing precision

Solution Approach 1:

The patent merges information from multiple processing stages by embedding metadata that contains information about post-production editing parameters, reference display characteristics, and creative intent settings into the video data stream. This allows downstream processing stages to access information from prior stages without requiring complex inter-stage communication infrastructure, preserving creative intent while avoiding excessive system complexity.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Systems, apparatus and methods are provided for generating, delivering, processing and displaying video data to preserve the video creator's creative intent. Metadata which may be used to guide the processing and display of the video data is dynamically generated and embedded in the video data throughout a video delivery pipeline. The metadata may be written in chrominance data for black video frames, black mattes or bars framing an image, and/or in the other image areas for which luminance values are zero or below a threshold value.
