Video Communication System With Multiple Input Sources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packet-based video communication systems lack the ability to effectively convey contextual information, such as shared experiences and surroundings, which can lead to more cumbersome or confused interactions during remote video calls.
Innovation Solution
A method and system that enable bidirectional video communication by establishing a channel between terminals in a packet-based network, allowing users to transmit video data from sources other than traditional webcams, such as TV streams or auxiliary video devices, to enhance the sharing of ideas and context during video calls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional webcam-only video communication is used, then the system is simple and easy to operate, but the ability to convey contextual information and shared experience is limited
Solution Approach 1:
The video communication system is enhanced to accept multiple video input sources including webcams, television receivers, camcorders, and auxiliary video devices. This multi-functionality allows the same communication system to convey diverse contextual information while maintaining a unified interface for users.
Solution Approach 2:
A signal processing apparatus is introduced as an intermediary component that receives video signals from various sources (television receiver, camcorder, auxiliary devices) and processes them for transmission over the packet-based communication network. This mediator enables diverse video sources to integrate seamlessly into the existing communication infrastructure.
2Ease of operation
If multiple video sources are integrated into video calls, then contextual information sharing is improved, but the device complexity increases
Solution Approach 1:
The system provides user-selectable functionality where users can choose which video sources to activate during their calls. The terminal automatically manages multiple video streams based on user selections, handling the complexity of source integration while keeping the user interface simple and intuitive.
3Adaptability or versatility
If packet-based communication networks are used, then cost is reduced compared to fixed line networks, but the ability to transmit diverse video content may be compromised
Solution Approach 1:
The signal processing apparatus dynamically adjusts video signal parameters including encoding formats, compression levels, and data transmission parameters to optimize the transmission of diverse video content over packet-based networks. This allows the system to adapt to varying network conditions and content types while maintaining transmission quality.

AI summary
A method of transmitting video data comprising: establishing a bidirectional video channel between a first terminal and a second terminal in a packet-based communication network; beginning a live, face-to-face video call over the established channel by generating first video data from a video camera of the first terminal, transmitting the first video data to the second terminal for display on a screen of the second terminal, receiving second video data generated from a video camera of the second terminal, and displaying the second video data on a screen of the first terminal; generating third video data at the first terminal from a source other than the video camera of the first terminal; receiving a user selection at the first terminal; and in response to the user selection, transmitting the third video data to the second user over the established channel of the packet-based communication network.
