Split-Screen Teleconferencing With Device Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video and audio teleconferencing systems require each endpoint to have a built-in camera and microphone or direct connection to external devices, limiting flexibility in device configurations and user experience, especially when participants want to use different devices for input and output.
Innovation Solution
A system that allows a user to conduct a teleconference using a split-screen configuration where input data is received on one device (e.g., a smartphone with a camera and microphone) and output data is presented on another device (e.g., a smart television), facilitated by session management protocols like SIP and presence detection, enabling communication between multiple network endpoints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each endpoint requires a built-in camera and microphone, then the teleconference can be conducted reliably, but the device complexity and cost increase
Solution Approach 1:
The teleconference system is segmented into separate input and output endpoints, allowing different devices to fulfill different roles. The input endpoint (smartphone) captures media while the output endpoint (television) displays it, eliminating the need for each device to have both camera and microphone built-in.
Solution Approach 2:
The system enables devices to serve multiple functions across different endpoints. A smartphone can serve as an input device for one user while a television serves as an output device for another, making the system more versatile and reducing individual device requirements.
2Reliability
If each endpoint must have camera and microphone, then communication is reliable, but the ease of operation decreases due to limited device flexibility
Solution Approach 1:
By separating input and output requirements into different devices, the system allows users to leverage devices with specialized capabilities. The smartphone with its camera and microphone serves as the input endpoint, while the television with its display serves as the output endpoint, improving ease of operation.
Solution Approach 2:
The network acts as an intermediary that connects the input endpoint (smartphone) and output endpoint (television), enabling communication without requiring both devices to have full teleconference capabilities. This mediator approach enhances device flexibility while maintaining communication reliability.
3Device complexity
If a single device is used for both input and output, then device complexity is reduced, but adaptability decreases when users want different devices
Solution Approach 1:
The system dynamically assigns different devices to different endpoints based on user needs. The input endpoint and output endpoint are not fixed to specific devices but can be dynamically configured, allowing adaptability while maintaining reasonable system simplicity through automated session management.
Solution Approach 2:
The teleconference system achieves universality by allowing any device with appropriate capabilities to serve as input or output endpoint. This multi-functional approach enhances adaptability while keeping the overall system simple through standardized protocols like SIP for session management.
4Adaptability or versatility
If multiple devices are associated with a single user, then adaptability improves, but device complexity increases
Solution Approach 1:
The session management server acts as an intermediary that handles the complexity of associating multiple devices with a single user. It manages the SIP sessions, tracks device availability, and coordinates communication between input and output endpoints, thereby improving adaptability while containing complexity in a centralized manager.
Solution Approach 2:
The system enables self-service through automated session management. When a user initiates a teleconference, the system automatically detects available devices, establishes appropriate input and output endpoints, and manages the connection without requiring manual configuration, thus improving adaptability while minimizing perceived complexity.
