Video Display View Settings Adaptation for Scene Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users with conventional standard resolution television sets cannot fully utilize higher resolution video signals, such as 4K, as their devices can only display at traditional standards like HD, leading to downscaling of the full image, and interactive view selection is not properly maintained during scene changes.
Innovation Solution
A method and apparatus that allow users to define and apply personalized view settings for different camera views, using metadata to detect scene changes and apply corresponding settings, enabling users to select and modify views interactively, even on lower resolution displays by converting higher resolution signals to match their device capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If higher resolution video signals (e.g., 4K) are transmitted, then video quality and detail are improved, but compatibility with conventional standard resolution television sets is worsened
Solution Approach 1:
The video signal is segmented into multiple views corresponding to different camera angles. Each view can be independently processed and transmitted, allowing receivers to select and display only the views compatible with their resolution capabilities while maintaining overall video quality for advanced devices.
Solution Approach 2:
The system dynamically adapts the video signal processing based on the receiver's capabilities. View settings are automatically adjusted according to the device's resolution, enabling the same high-resolution signal to be optimally displayed on both standard and advanced television sets without loss of compatibility.
2Ease of operation
If individual interactive view selection is implemented, then user interactivity is improved, but maintenance of view settings during scene changes is worsened
Solution Approach 1:
The system uses feedback mechanisms where view settings are stored and automatically retrieved when scenes change. The receiver monitors scene changes and automatically applies the previously selected view settings for the new scene, maintaining user preferences across scene transitions without requiring manual reselection.
Solution Approach 2:
View settings are predetermined and stored for different scenes and camera views. When a scene change occurs, the system has already prepared the appropriate view settings in advance, allowing immediate automatic application without interrupting the user experience or requiring real-time user input.
3Adaptability or versatility
If full image downscaling is applied to match standard resolution displays, then device compatibility is improved, but video quality is worsened
Solution Approach 1:
Instead of uniformly downscaling the entire image, the system applies selective processing where only the necessary portions of the high-resolution signal are processed for standard resolution displays. Advanced displays receive the full high-resolution signal without downscaling, while standard displays receive optimized versions, allowing each device to display video quality appropriate to its capabilities without unnecessary quality loss.

AI summary
Television broadcast standards are continuously improved and new standards are introduced, often with increased resolution. Many users keep their television set that cannot take advantage of the improvements. However, in a case where a higher resolution video signal is available, additional services can be provided to the users of standard resolution television sets. A method for displaying a video comprises steps of enabling a user to define (71) first view settings, applying (72) the first view settings to a first view of a first video scene, determining (73) a first camera corresponding to the first view, storing (74) the first view settings, after a scene change towards a new scene detecting (76) that the new scene corresponds to the first view, and automatically applying (78) the first view settings for displaying the new scene.
