Active Screen Display Offline Content Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Personal computer displays remain idle and consume energy when not in use, and there is a lack of convenient and automated methods to transfer content from a personal computer to an active display for offline viewing, especially when the computer is turned off or inactive.
Innovation Solution
A system and method that encodes content using a processor and decodes it on an active screen display for unilateral display without the need for the personal computer's active computational resources, utilizing a physical display interface connection and error correction mechanisms to ensure reliable data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If conventional software applications are used to display content on the personal computer display, then the display can show pictures, calendar, or advertisements, but the personal computer must remain turned on consuming energy and remaining vulnerable to malicious software
Solution Approach 1:
The patent extracts the content display functionality from the personal computer system and relocates it to a standalone active display device. The display device independently retrieves content from external media (such as USB drives or SD cards) and displays it without requiring the personal computer to be running, thereby eliminating energy consumption and security vulnerabilities associated with keeping the PC on.
Solution Approach 2:
The active display device is equipped with onboard storage, external media readers, and internal logic to autonomously display content without requiring active computational resources from the personal computer. The device self-manages content retrieval, processing, and display, making the system independent and eliminating the need for the PC to remain powered on.
2Ease of operation
If manual loading of content from external media is implemented in the active display, then the display can show content without the personal computer, but the user experience is inconvenient and costs are increased due to replicating user interface controls
Solution Approach 1:
The active display device incorporates multiple functions including external media reading, onboard storage, and content display capabilities in a single unified device. This multi-functionality eliminates the need for separate user interface controls on the display, as content can be loaded directly from various external media sources without requiring complex control mechanisms.
Solution Approach 2:
The patent uses the personal computer as an intermediary to transfer content to the active display's onboard storage. The PC serves as a content preparation station where users can organize and prepare content, which is then transferred to the display device. This intermediary approach simplifies the display device's interface requirements while maintaining ease of content management.
3Extent of automation
If a special purpose cable or wireless interconnect is used to transfer content from the personal computer to the active display, then automated content transfer is achieved, but matching and compatible computers and displays are required along with specialized hardware for communication and installation labor
Solution Approach 1:
The active display device incorporates universal external media readers that can directly read from common storage formats (USB drives, SD cards, etc.), eliminating the need for specialized communication hardware or cables. This universal interface approach allows any standard media player or computer to transfer content without requiring proprietary connections or matching hardware.
Solution Approach 2:
The patent replaces mechanical connection systems (specialized cables and physical connectors) with direct media insertion capabilities. The display device can directly read from external media without requiring physical connection to the personal computer, substituting complex mechanical interfacing with simpler, more universal media access methods.
Data Source
AI summary
A system and method for offline content delivery through an active screen display is provided. Data for display and content to be displayed at a later time are encoded as a display signal for delivery. An active screen display is associated with a computer and coupled to a processor over a physical display interface connection. The display signal is received and decoded to distinguish the data for display from the content to be displayed at a later time. The content to be displayed at a later time is displayed via the active screen display when the computer is one of turned off and inactive.
