Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video transmission technologies are limited in simultaneously or separately mirroring videos from multiple sources via wireless transmission, preventing effective implementation of video mirroring according to user demands.
Innovation Solution
A video stream processing apparatus with a processor and non-transitory storage medium, equipped with modules for establishing wireless connections with multiple source devices, receiving mirror videos, and controlling screen displays to show these videos separately or simultaneously, using standards like WiFi Direct and multicast groups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless video transmission uses one-to-one mirroring, then video transmission reliability is improved, but device versatility deteriorates
Solution Approach 1:
The display device is designed to simultaneously support multiple wireless video connections (first wireless connection and second wireless connection) with different source devices, enabling it to function as both a single-source and multi-source video display system. This multi-functionality allows the device to adapt to various usage scenarios including mirror display, split screen, and picture-by-picture modes.
Solution Approach 2:
The system dynamically switches between different display modes (mirror display, split screen, picture-by-picture) based on user selection and operational conditions. The display device can transition from a static one-to-one mirroring mode to a dynamic multi-source configuration, adjusting its functionality in real-time to meet different user needs.
2Adaptability or versatility
If the system supports multiple video sources, then device versatility is improved, but system complexity increases
Solution Approach 1:
The display device processes each video source independently through separate wireless connections and dedicated processing channels. The first video source and second video source are handled through distinct pathways that can be independently controlled, managed, and optimized, reducing the overall system complexity despite supporting multiple sources.
Solution Approach 2:
The system merges multiple independent video processing channels into a unified display output mechanism. By combining the first video processing result and second video processing result through a single display interface, the system achieves multi-source capability while maintaining manageable complexity through integrated control.
3Adaptability or versatility
If wireless connections are established with multiple devices, then adaptability is improved, but connection management complexity increases
Solution Approach 1:
The display device acts as an intermediary that manages multiple wireless connections to source devices. It provides a centralized control point for establishing, maintaining, and switching between different wireless connections, simplifying the management complexity by offering unified connection handling rather than requiring direct peer-to-peer management between multiple devices.

AI summary
A video stream processing apparatus, a method for display mirror video and a display device are provided. The video stream processing apparatus includes a connection establishing module, a mirror video receiving module, and a mirror video display module. The connection establishing module is configured to establish a first wireless connection with a first source device, and establish a second wireless connection with a second source device. The mirror video receiving module is configured to receive a first mirror video from the first source device through the first wireless connection, and receive a second mirror video from the second source device through the second wireless connection. The mirror video display module is configured to control a screen to separately display the first mirror video or the second mirror video, or simultaneously display the first mirror video and the second mirror video.
