Audio Stream Redirection for Lower-Bandwidth Display-Server Computing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display-server computing systems require significant bandwidth for transmitting audio and video data between servers and end-user devices due to the need for double bandwidth usage, one for communication to the server and another for communication to the end-user device.
Innovation Solution
A system where a user device reformats audio and video data to include only what the server computer needs for application operation, reducing data size, and the server transforms it back to the original format before handing it off to the application unit, minimizing data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If audio/video data is retrieved by the server computer and communicated to the user device, then the application unit can operate with audio/video data, but the bandwidth requirement is doubled and becomes significant
Solution Approach 1:
The patent inverts the conventional data flow direction. Instead of the server fetching audio/video data from an audio/video server and forwarding it to the user device (double bandwidth consumption), the user device directly requests and receives audio/video data from the audio/video server, then forwards only necessary reformatted data to the server computer running the application unit. This inversion eliminates the need for the server to retrieve and re-transmit the full audio/video streams.
Solution Approach 2:
The user device extracts and reformats only the essential audio/video data needed for application operation, separating the full audio/video stream from the minimal processed data. By taking out only the necessary components and reformating them, the system reduces the data量 transmitted between server and user device, directly addressing the bandwidth consumption issue while maintaining application functionality.
2Ease of operation
If the server computer retrieves audio/video data from an audio/video server and forwards it to the user device, then the application can access audio/video data, but the data transmission becomes inefficient and bandwidth-intensive
Solution Approach 1:
The user device acts as an intermediary between the audio/video server and the server computer running the application unit. Instead of the server computer directly retrieving and forwarding audio/video data, the user device receives the full audio/video streams from the audio/video server, reformats them to extract only necessary information, and then transmits this condensed data to the server computer. This intermediary approach significantly improves data transmission efficiency while maintaining ease of data access.
Solution Approach 2:
The user device changes the parameters of the audio/video data by reformating it from the original stream format to a condensed, application-specific format. This parameter transformation reduces the data size and optimizes transmission efficiency, allowing the server computer to access audio/video information with minimal bandwidth consumption while maintaining operational ease.
3Adaptability or versatility
If audio/video data is transmitted through the server computer to the user device, then the server can provide application services, but the bandwidth requirement doubles and network resources are consumed inefficiently
Solution Approach 1:
The patent segments the audio/video data processing into distinct functional components: the user device handles receiving full audio/video streams from the audio/video server and performing reformatting, while the server computer running the application unit only processes the condensed, reformatted data. This segmentation allows each component to perform its specific function efficiently, maintaining server versatility while minimizing network bandwidth consumption.
Solution Approach 2:
The user device serves as an intermediary that bridges the audio/video server and the server computer, handling the bandwidth-intensive tasks of receiving full audio/video streams and reformating them. This intermediary role protects the server computer from direct bandwidth consumption, allowing it to maintain its computing versatility while the user device manages the network resource consumption efficiently.

AI summary
A system operative on a data communications network to operate on an audio/video data includes a server computer communicatively connected to the network. The server computer includes an application unit running an application program. The application program is accessible to a user device communicatively connected to the network. The application unit requires the audio/video data to run the application program. The system also includes an audio/video server computer communicatively connected to the network. The audio/video server computer communicates the audio/video data over the network responsive to a request. The user device includes at least a buffer, a decoder and an output device. The need request is sent by the server computer over the network to the user device, for receipt of the audio/video data for operation of the application unit. The need request includes an identifier of the audio/video data and a network address of the audio/video server computer. The user device, upon receipt of the need request, requests communicatively over the network to the audio/video server computer and the audio/video server computer delivers communicatively over the network the audio/video data to the user device. The user device reformats the audio/video data and delivers the reformatted audio/video data to the server computer. The server computer reverses the reformatted audio/video data to obtain substantially the original audio/video data for operations of the application unit.
