Wireless Display Accessing Remote Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large wireless displays face significant bandwidth utilization and delay issues when transmitting display data from a computer, especially when accessing and rendering content from remote sources, leading to inefficient use of available bandwidth and internal computer resources.
Innovation Solution
The computer instructs a display device to access content from remote resources and combine it with locally processed content, using resource identifiers and authentication parameters embedded in messages, allowing the display device's processor to directly retrieve content from remote servers, reducing the need for extensive data transmission over the wireless connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the computer processes and transmits all display data over the wireless connection, then the display data can be rendered on the wireless display, but bandwidth utilization becomes inefficient and transmission delays increase
Solution Approach 1:
The patent segments display data into two categories: local content (processed by the computer) and remote content (accessed directly by the wireless display from remote servers). This segmentation allows each type of content to be handled through the most efficient path, reducing overall transmission delay and improving bandwidth utilization.
Solution Approach 2:
The patent extracts remote content access functionality from the computer and transfers it to the wireless display. The wireless display now directly accesses remote content from servers without requiring the computer to fetch and transmit it, thereby eliminating unnecessary transmission steps and reducing delay.
2Productivity
If the computer accesses and renders remote content locally before transmission, then the content can be displayed, but bandwidth utilization and internal computer resources are inefficiently used
Solution Approach 1:
The patent extracts the remote content access function from the computer and assigns it to the wireless display. The wireless display now directly retrieves remote content from servers using embedded network interfaces, eliminating the need for the computer to download and process this content locally, thus reducing computer resource consumption.
Solution Approach 2:
The wireless display performs self-service by directly accessing remote content from servers without requiring the computer to intermediat e the data transfer. The display device independently handles remote content retrieval and combines it with locally processed content, reducing the computational burden on the computer.
3Reliability
If all content is transmitted over the wireless connection, then the display can be updated, but the wireless connection bandwidth is overwhelmed
Solution Approach 1:
The patent segments the data transmission pathway into two channels: local content transmitted over the wireless connection and remote content accessed directly by the wireless display from servers. This segmentation significantly reduces the volume of data that must traverse the wireless connection while ensuring both content types are delivered reliably.
Solution Approach 2:
The wireless display acts as an intermediary that directly communicates with remote servers to obtain content. This intermediary role allows the display to bypass the computer for remote content retrieval, reducing the data burden on the wireless connection between computer and display.
Data Source
AI summary
Problems of bandwidth utilization and delay, with a computer having a wirelessly connected display, are addressed by having the computer instruct a display device to access content from remote resources and combine that content with content processed locally at the computer and sent to the display device. The display device includes a processor, or display computer, associated with a display. When the computer transmits data to the display device, the data includes information indicating the resource, such as a server accessible over a computer network, which stores the content to be displayed. The processor associated with the display uses this information to access the content directly from its resource. The processor associated with the display can be embedded in the housing for the display or can be housed in a separate housing that is electrically connected directly to the display.
