QR Code Authorization for Disconnected Satellite TV Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Satellite television systems face issues with content authorization loss due to unconnected user receiving devices that cannot perform handshake procedures with service providers, leading to interrupted access to subscribed content.
Innovation Solution
Implementing a system that uses mobile devices with imaging and text message capabilities to acquire and transmit images or text messages from user receiving devices to a head end or content provider, generating authorization signals for content access, allowing reauthorization and access to content without requiring internet connectivity or direct communication with the service provider.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If user receiving devices are disconnected from the network, then device autonomy and accessibility are improved, but content authorization and reauthorization functionality deteriorate
Solution Approach 1:
The system performs preliminary actions by capturing authorization codes and generating QR codes while the device is connected. The QR code contains pre-encoded authorization information that can be later redeemed without requiring network connectivity, allowing the device to operate autonomously even when disconnected.
Solution Approach 2:
The QR code serves as an intermediary carrier that bridges the gap between connected and disconnected states. It encapsulates authorization data in a portable format that can be transferred to mobile devices and redeemed later, maintaining authorization reliability independent of network availability.
2Reliability
If traditional handshake procedures are required for content access, then security and authorization control are improved, but system complexity and user effort increase
Solution Approach 1:
The invention extracts the essential authorization data from the complex handshake procedure and encapsulates it in a QR code. This extracted authorization information can be redeemed directly without requiring the full handshake protocol, simplifying the access process while maintaining security through the encoded authorization data.
Solution Approach 2:
Instead of requiring devices to perform complex handshake procedures, the system creates a copy of the authorization state in the form of a QR code. This copy can be transferred and redeemed on different devices, eliminating the need for repeated authentication handshakes while preserving authorization control.
3Productivity
If QR codes and text message systems are implemented, then reauthorization speed and user convenience are improved, but system implementation complexity increases
Solution Approach 1:
The invention replaces complex mechanical handshake procedures with optical (QR code) and electromagnetic (text message) communication methods. Mobile device cameras capture QR codes and text messages are transmitted wirelessly, eliminating the need for direct device-to-head-end communication protocols and significantly accelerating the reauthorization process.
Data Source
AI summary
A mobile device including a content module, an imaging module, and an interface. The content module is configured to attempt to access content including transmitting a content request signal from the mobile device to a user receiving device. The imaging module is configured to acquire an image of at least a portion of a screen shown on a display connected to the user receiving device. The interface is configured to transmit the image or information pertaining to the image to the user receiving device, a head end or a content provider to cause the user receiving device or the mobile device to receive an authorization signal for access to the content.
