Stream Relay Gateway for P2P Video Protocol Translation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current peer-to-peer networking systems for video streaming are limited by tight integration of streaming technology with peer-to-peer technology, lack of standardization in video formats, and requirements for specific CODECs, which restricts flexibility and compatibility across different nodes and devices.
Innovation Solution
A method for streaming digital video assets over a distributed network using standard video stream formats, where a stream relay client captures and converts video streams into a compatible form for peer-to-peer links, allowing any node to stream video using standard servers and clients without modification, and utilizing the RTSP protocol for control and data transmission, enabling transcoding and resolution adjustment based on node capabilities.

Engineering Contradiction Analysis
1Adaptability or versatility
If peer-to-peer streaming is implemented with tight integration of streaming technology and peer-to-peer technology, then video streaming can be achieved over distributed networks, but flexibility and compatibility across different nodes and devices are restricted due to lack of standardization and specific CODEC requirements
Solution Approach 1:
The patent introduces a gateway as an intermediary component that bridges standard video streaming protocols (RTSP, RTP) and peer-to-peer communication protocols. The gateway translates and adapts between these different protocol layers, allowing standard video servers and clients to communicate over peer-to-peer networks without requiring tight integration or custom modifications. This mediator approach resolves the contradiction by maintaining standardization while enabling peer-to-peer functionality.
Solution Approach 2:
The system architecture is segmented into distinct functional layers: video source, video server (using standard RTSP/RTP), gateway (handling protocol translation and peer-to-peer link management), and video client. This segmentation allows each component to operate independently with standard interfaces, improving compatibility across different nodes while distributing complexity across multiple specialized components rather than requiring every component to handle both streaming and peer-to-peer protocols simultaneously.
2Productivity
If video files are transferred completely from one computer to another, then the user can view the video, but the user experiences long delays because video files are often large
Solution Approach 1:
The system implements continuous video streaming where video data is transmitted in real-time packets over the peer-to-peer network as the user views the video, rather than completing a full file transfer first. The video server continuously sends video packets through the gateway to the client, allowing the user to watch the video progressively without waiting for the entire file to transfer. This eliminates the idle waiting time while maintaining continuous video playback.
3Ease of operation
If video streaming is implemented without file transfer, then no delay is experienced and control over the video file is maintained, but existing systems require uploading videos to central servers which is troublesome and expensive
Solution Approach 1:
The gateway serves as a lightweight intermediary that enables direct peer-to-peer video streaming without requiring central server storage. Unlike YouTube-style platforms where videos must be uploaded to and stored on central servers, this system uses the gateway only for protocol translation and connection management, while the actual video data flows directly between peer nodes. This eliminates both the upload hassle and the expensive central server storage requirements.
Solution Approach 2:
Each peer node in the network serves itself by hosting and streaming its own video files directly to other peers through the gateway. Users don't need to upload videos to centralized servers; instead, the video sharing system leverages the distributed storage capacity of individual peer nodes themselves. This self-service approach eliminates central server storage costs while maintaining ease of video sharing through the standardized gateway interface.

AI summary
A method for viewing digital video assets using a distributed network comprising a user on a first node requesting to view a digital video asset stored on a second node; relaying the request from the first node to the second node; establishing a peer-to-peer link between the first and second nodes; creating a video stream from the requested digital video asset on the second node using a standard video stream server; receiving the video stream using a stream relay client on the second node and converting it into a form that is compatible with the peer-to-peer link; sending the converted video stream to the first node over the peer-to-peer link; receiving the converted video stream using a stream relay server and converting it into a standard video stream form; and viewing the video stream on the first node of the distributed network using a standard video stream client.
