IP Network Background Skin Segmentation for VoIP
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current VoIP video conversations lack visual appeal, as they typically display only the images of participants without any background, making them uninteresting and unpersonalized.
Innovation Solution
A method and apparatus for applying a background skin in an IP network during video calls, where terminals exchange and display background skin data separately from multimedia data, allowing users to select and change backgrounds during calls without requiring additional hardware for data mixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If background skin data is transmitted separately from multimedia data, then data transmission efficiency is improved, but system complexity increases
Solution Approach 1:
The patent segments the data transmission into two separate channels: background skin data and multimedia data. Background skin data is transmitted using TCP protocol for reliable delivery, while multimedia data is transmitted separately. This segmentation allows each type of data to be optimized independently, improving overall transmission efficiency without requiring complex real-time mixing hardware.
2Adaptability or versatility
If background skin is applied to video calls, then visual appeal is improved, but data transmission complexity increases
Solution Approach 1:
The patent introduces background skin data as an intermediary element that enhances the visual appearance of video calls without directly modifying the multimedia transmission process. The background skin is transmitted separately and displayed alongside the video feed, providing visual personalization while keeping the core video transmission simple and efficient.
3Reliability
If background skin data is transmitted using TCP protocol, then data reliability is improved, but transmission speed decreases
Solution Approach 1:
The patent segments data transmission into different protocols based on requirements: TCP is used for background skin data where reliability is crucial, while multimedia data can use faster but less reliable protocols. This segmentation allows the system to prioritize reliability for control data (background skins) while maintaining speed for time-sensitive multimedia content.

AI summary
In a method and apparatus for applying a background skin in an Internet protocol (IP) network, a first terminal sends a call request message, including background skin index information, to a second terminal. The second terminal sends a response message, including background skin index information, to the first terminal in response to the received call request message. The first terminal and the second terminal separately receive and display background skin data transmitted between the first terminal and the second terminal, and display multimedia data transmitted and received during a session established between the first terminal and the second terminal, together with the background skin displayed on each terminal.
