Server-Mediated Mobile Multimedia Sharing Under Bandwidth Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless mobile data networks have limitations in bandwidth and processing power, hindering efficient transmission of multimedia content such as photos and videos between mobile communication devices.
Innovation Solution
A system and method for transmitting video content between mobile communication devices using a server, where a first device sends a share request to a second device, which can accept or reject the request, and content is transmitted only if the request is accepted, with separate channels for video and audio, and utilizing protocols like TCP and UDP for data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless mobile data networks are used to transmit multimedia content, then users can share photos and videos wirelessly, but the transmission efficiency is reduced due to bandwidth limitations
Solution Approach 1:
The patent introduces a server as an intermediary component that mediates between the first and second mobile communication devices. The server receives share requests, manages authentication, and coordinates the multimedia content transmission process, thereby optimizing the use of limited wireless bandwidth while maintaining ease of wireless sharing operation.
2Speed
If mobile communication devices process and transmit multimedia content, then users can share content in real-time, but the processing power limitations reduce transmission speed
Solution Approach 1:
The server acts as a powerful intermediary that handles complex processing tasks such as authentication, session management, and transmission coordination. This offloads processing requirements from the mobile devices themselves, enabling real-time sharing speeds without exceeding the processing power limitations of the mobile communication devices.
3Reliability
If a share request system is implemented, then users can control content transmission based on acceptance, but the transmission process becomes more complex
Solution Approach 1:
The server implements the share request and acceptance logic as an intermediary process. When the first device sends a share request, the server manages the request flow, waits for acceptance from the second device, and only then initiates transmission. This centralizes the complexity of the control logic in the server, keeping the mobile device implementations relatively simple while ensuring reliable user-controlled transmission.

AI summary
A first mobile communication device is configured to transmit video and audio content to a second mobile communication device utilizing a server. The first mobile communication device, via the server, transmits a share request or “knock” with the second mobile communication device. The second device must either accept the request or reject the request. If the second mobile communication device accepts the knock, it transmits a share accept message to the server. The first mobile communication device then transmits the video and audio content to the second mobile communication device via the server.
