Flat Panel Display Wireless Identity Broadcast for Handheld Data Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies do not allow users to access data associated with video programming on multiple co-located flat panel displays from portable wireless handheld devices, limiting interaction and data retrieval in public venues where multiple screens are present, such as sports bars and stadiums.
Innovation Solution
Implementing a mediacasting system that enables flat panel displays to wirelessly broadcast their identity and data, allowing handheld devices to capture and match images of video programming with a remote server, providing access to associated data, including past content, through wireless standards like Bluetooth, WiFi direct, and cellular data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple flat panel displays are co-located in public venues, then more video content is available for spectators, but it becomes difficult for users to identify and access data from specific screens
Solution Approach 1:
The patent introduces an intermediary system consisting of screen identification codes displayed on each flat panel and a corresponding mobile application that acts as a mediator between the spectator and the multiple screens. The application captures images of these codes, identifies the specific screen, and retrieves associated data, thereby solving the problem of identifying and accessing content from specific screens among multiple co-located displays.
2Loss of information
If data is accessed from remote servers based on program names or access codes, then data retrieval is possible, but the process becomes complex and time-consuming
Solution Approach 1:
The patent implements preliminary action by pre-displaying unique identification codes on each flat panel screen and pre-storing associated video data and metadata on remote servers. When a user points their mobile device at a screen, the identification is immediately recognized and the corresponding data is rapidly retrieved, eliminating the need for manual program name entry or code searching, thus significantly reducing data retrieval time.
3Adaptability or versatility
If wireless data sharing is implemented from handheld devices to flat panels, then media sharing is enabled, but reverse data delivery from flat panels to handheld devices is not available
Solution Approach 1:
The patent inverts the traditional unidirectional data flow by implementing bidirectional communication capabilities. Instead of only allowing data to flow from handheld devices to flat panels, the system enables flat panel displays to transmit video data, metadata, and identification information back to handheld devices through the mobile application, creating a complete two-way data exchange system.
Data Source
AI summary
Flat panel displays can broadcast their identity for discovery by handheld devices interested in obtaining data associated with video programming displayed on the displays. An application can be downloaded and activated on smartphones that will enable them to capture an image of the video programming and recognize is with the help of a remote server, or wirelessly obtain a list of available (discovered) flat panel displays (multiple screens, depending on venue) that allow wireless access to data associated with video programming displayed (or previously displayed and stored in a queue) on flat panels. Video programming rendering on a flat panel of interest can be identified via the smartphone and the smartphone can access additional data either directly from the flat panel or from a remote server once the data has been identified and/or engage in an interactive session in association with the displayed programming or data.
