Multi-screen Video Playback System Dynamic Region Scaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional single-screen video playback systems fail to provide high-quality zoomed-in images due to insufficient video resolution and image scaling performance, and they cannot simultaneously display zoomed-in versions of different image areas to multiple audiences, limiting user interaction and content diversity.
Innovation Solution
A multi-screen video playback system that includes a video playback device, a portable communication device, and a multi-screen display controlling server, which dynamically generates and transmits scaled videos to portable devices, allowing users to zoom in on specific image areas without affecting the main display's content integrity, and supports multiple simultaneous scaled video streams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the video resolution is increased to improve image quality of zoomed-in areas, then the image quality is improved, but the system complexity and cost increase
Solution Approach 1:
The patent divides the video display into multiple independent regions, each capable of being independently scaled and displayed on different screens. The display area is segmented into a first display area on the first screen and a second display area on the second screen, allowing separate control and rendering of video content in each region. This segmentation enables the system to provide high-quality zoomed-in views without requiring the entire system to operate at maximum resolution, thus reducing overall complexity while maintaining image quality in specific areas of interest.
2Measurement precision
If a single screen displays a zoomed-in version of a specific image area, then the image details are improved, but the integrity of the video content is blocked out
Solution Approach 1:
The patent transitions from a two-dimensional single-screen display to a multi-dimensional multi-screen display arrangement. By utilizing multiple screens positioned in different spatial dimensions, the system can simultaneously display the full video content on one screen while providing zoomed-in detailed views on other screens. This dimensional expansion allows users to view both the overall video integrity and specific image details concurrently, eliminating the trade-off between viewing the complete content and examining detailed areas.
3Measurement precision
If the traditional single-screen system displays zoomed-in content, then specific image area details are enhanced, but multiple audiences cannot simultaneously view different image areas
Solution Approach 1:
The patent creates a multi-functional display system where multiple screens serve different purposes simultaneously. The first screen displays the main video content while the second screen provides zoomed-in detailed views. This universal system can accommodate multiple audiences with different viewing preferences and interests, allowing each audience member to view different image areas or different levels of zoom on different screens. The system thus achieves both detailed image area enhancement and multi-audience support through its multi-screen architecture.
4Measurement precision
If the video playback system uses high video resolution to improve zoomed-in image quality, then the image scaling performance is improved, but the loss of time for processing and transmitting video data increases
Solution Approach 1:
The patent extracts only the necessary portions of the video content for zoomed-in display rather than processing and transmitting the entire high-resolution video stream. The system identifies specific image areas of interest and extracts only those regions for enhanced display on the second screen. This extraction approach significantly reduces the amount of data that needs to be processed and transmitted, thereby maintaining high zoomed-in image quality while minimizing the time loss associated with video processing and transmission.

AI summary
A multi-screen video playback system includes: a video playback device having a main display, a portable communication device having a screen, and a multi-screen display controlling server. The multi-screen display controlling server transmits a target video to the video playback device via a network so that the video playback device utilizes the main display to display the target video. While the main display displays the target video, if the multi-screen display controlling server received a selection message corresponding to a position of a partial region of the main display, the multi-screen display controlling server dynamically generates a scaled video corresponding to images displayed on the partial region and transmits the scaled video to the portable communication device via a network so that the portable communication device simultaneously displays the scaled video on the screen.
