Portable Device Web Server for External Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices face limitations in effectively sharing media due to size and resource constraints, making it difficult to display digital media to large groups or at sufficient resolution.
Innovation Solution
A system that establishes a network connection between a portable electronic device and a web browser using a service discovery protocol, allowing the portable device to send data and control instructions to the web browser for displaying digital media, such as images, web applications, or documents, enabling users to control the display of media on larger devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If media is displayed on the portable electronic device's display screen, then the device can show digital media to users, but the display screen is too small to show pictures to a large group of people or at sufficient resolution
Solution Approach 1:
The patent uses a web server as an intermediary between the portable electronic device and the web browser on the display device. The web server receives media data from the portable device, processes it, and transmits it to the web browser for display on the larger screen, enabling the portable device to leverage external display capabilities while maintaining control over the media content
Solution Approach 2:
The system enables the portable electronic device to function not only as a local display device but also as a remote control and media source for external devices with larger displays. The web server implementation allows the portable device to serve multiple functions: storing media, processing media, controlling display parameters, and managing network communication
2Adaptability or versatility
If a web server is implemented on the portable electronic device to enable media sharing, then media can be displayed on larger devices, but the device complexity increases
Solution Approach 1:
The portable electronic device leverages its existing web server functionality (common in modern smartphones and tablets) to perform media sharing operations. By using an already-present component for a new purpose, the system avoids adding significant complexity while enabling media sharing capabilities
Solution Approach 2:
The web server on the portable device automatically handles media processing, format conversion, and transmission protocols without requiring additional user configuration or complex setup procedures. The system self-manages the complexity of network communication and media delivery
Data Source
AI summary
Some embodiments provide a system for interacting with a web browser. During operation, the system establishes a network connection with the web browser from a portable electronic device. Next, the system provides data to the web browser using a web server on the portable electronic device. Finally, the system sends a set of control instructions from the web server to the web browser, wherein the control instructions direct the web browser to obtain and display the data.
