Multi-Screen Video Playback via Server Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional video playback systems are limited to single-screen displays, making it difficult for movie or TV producers to present multiple viewing angles simultaneously, resulting in a less diverse and engaging experience for audiences.
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 establishes a device group relationship and transmits target and auxiliary videos over a network, allowing the portable device to display auxiliary content synchronously with the main display, enhancing the viewing experience by presenting different angles or perspectives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-screen display system is used, then the device complexity is low, but the viewing experience diversity is limited
Solution Approach 1:
A multi-screen display controlling server is introduced as an intermediary component to coordinate between the video playback device and portable communication device. The server manages device group relationships, synchronizes video playback, and controls the display of auxiliary videos, thereby enabling multi-screen functionality without requiring complex modifications to the endpoint devices themselves.
Solution Approach 2:
The portable communication device is utilized for dual purposes: its primary communication function and as an auxiliary display device for video playback. By repurposing an existing device with a screen for additional video display functionality, the system expands viewing options without adding dedicated display hardware, thus improving versatility while controlling complexity.
2Adaptability or versatility
If split-screen approach is used to display multiple viewing angles, then the viewing experience diversity improves, but the image integrity deteriorates
Solution Approach 1:
The video display is segmented across multiple independent screens rather than forcing a single screen to display multiple views simultaneously. The main display device shows the primary video with full image integrity, while the portable communication device displays auxiliary videos from different viewing angles. This spatial segmentation preserves the quality of each individual video feed while providing diverse viewing perspectives.
3Adaptability or versatility
If multiple cameras capture images from different angles, then the viewing experience diversity improves, but the device complexity increases
Solution Approach 1:
Instead of requiring multiple physical display devices, the system creates a virtual copy of the video playback functionality on the portable communication device. The auxiliary video content is transmitted and displayed on the portable device's screen, effectively copying the video playback experience to a second device. This approach enables multi-angle viewing without duplicating the entire playback system infrastructure.

AI summary
A multi-screen video playback system includes: a video playback device having a main display to playback a target video; a portable communication device having a screen; and a multi-screen display controlling server configured to operably establish a device group relationship between the video playback device and the portable communication device, to transmit the target video to the video playback device via a network, and to transmit an auxiliary video to the portable communication device via the network. The multi-screen display controlling server receives a notice information generated by the video playback device while the video playback device playbacks the target video, and instructs the portable communication device to begin displaying the auxiliary video on the screen according to the notice information.
