Solution Overview

Problem

Current video processing technologies struggle to provide a smooth transition between high dynamic range (HDR) video content and interstitial content items, such as advertisements, leading to visually unpleasing changes in brightness and darkness for viewers.

Innovation Solution

A method and device that detect transitions between different metadata-associated frames in a video sequence, controlling brightness properties of interstitial content to match those of the main video content, using a video transition controller to dynamically adjust visual properties for a seamless transition.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If HDR video format is used to provide wider brightness and darkness range, then picture detail and visual quality are improved, but the transition to interstitial content items becomes more apparent and visually unpleasing

Engineering Contradiction:
Improvebrightness rangeVSAvoidvisual discontinuity
Core Design Contradiction:
Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary detection of transitions between different video content types (e.g., HDR to SDR, different brightness ranges) before the actual content switch occurs. By detecting metadata changes in advance, the system can pre-adjust brightness and darkness parameters to ensure a smooth visual transition, preventing the harmful effect of abrupt visual changes while maintaining the benefits of HDR format.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If interstitial content items are displayed with their original visual properties, then content integrity is maintained, but visual appearance is not synchronized with main video content

Engineering Contradiction:
Improvecontent integrityVSAvoidvisual appearance consistency
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The system applies different visual property adjustments to different parts of the video stream based on local content characteristics. When interstitial content is detected, the system selectively adjusts brightness and darkness parameters only for that specific content segment while leaving the main video content unchanged. This localized adjustment maintains the integrity of the original content while ensuring visual synchronization at the boundaries between content types.

Inventive Principle:
Principle #3Local quality

3Object-affected harmful factors

If video transition controller adjusts visual properties of interstitial content, then smooth transition is achieved, but processing complexity increases

Engineering Contradiction:
Improvevisual discontinuityVSAvoidprocessing complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The system focuses on adjusting a limited set of critical visual parameters (brightness and darkness) rather than modifying all visual properties of the video content. By concentrating on these key parameters that have the most significant impact on visual continuity, the system achieves smooth transitions while minimizing processing complexity. The metadata-driven approach allows for automated parameter adjustment without requiring complex analysis of the entire video content.

AI summary

Various aspects of a video processing device and method for display control includes detection, from a sequence of image frames received from a video source, a transition from one or more frames associated with a first metadata to one or more other frames associated with a second metadata. First visual properties of the one or more frames are determined based on the first metadata. Second visual properties of the one or more other frames are determined based on the second metadata. The determined second visual properties of the one or more other frames are controlled in accordance with the determined first visual properties of the one or more frames to enable a smooth transition.
