Videoconference Terminal Secondary-Stream Data Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current videoconference terminals face issues with complex interfaces, requiring professional training, long audio/video cables, and inconvenient wiring due to the need for external devices for secondary-stream data transmission, affecting both aesthetics and signal quality.
Innovation Solution
A videoconference terminal with a built-in playing tool for secondary-stream data processing, allowing editing, deletion, marking, and plotting, and coding of video/audio data, which can be sent directly to a target terminal without external devices, reducing the number of interfaces and eliminating the need for long cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If external devices are connected to videoconference terminal for secondary-stream data transmission, then double stream transmission function is achieved, but terminal interface complexity increases and requires professional training for operation
Solution Approach 1:
The patent merges the external device connection function with the terminal's internal resources by introducing a virtual machine that can directly access terminal interfaces (camera, microphone, display) without requiring physical external devices. This integration eliminates the need for complex interface connections while maintaining double stream transmission capability.
Solution Approach 2:
The patent introduces a virtual machine as an intermediary layer between the user and terminal resources. This virtual machine handles secondary-stream data processing internally, acting as a mediator that eliminates the need for complex external device connections while preserving the required functionality.
2Adaptability or versatility
If external devices are connected for secondary-stream data, then double stream transmission is enabled, but wiring becomes inconvenient and signal quality deteriorates due to long cables
Solution Approach 1:
The patent extracts the secondary-stream processing function from external physical devices and relocates it to a virtual machine running within the terminal. This extraction eliminates the need for long physical cables and external device connections, thereby improving signal quality and reliability while maintaining the double stream transmission function.
3Adaptability or versatility
If multiple audio/video interfaces are provided in videoconference terminal, then secondary-stream data can be transmitted, but aesthetic appearance and structural strength are affected
Solution Approach 1:
The patent makes the terminal's existing interfaces universal by enabling a single set of physical interfaces (camera, microphone, display) to serve both main-stream and secondary-stream functions through virtual machine resource allocation. This multi-functionality eliminates the need for additional physical interfaces, preserving aesthetic appearance and structural integrity while maintaining secondary-stream transmission capability.
