Portable USB Dongle for Location-Independent DVR Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video content providers restrict media access to specific service areas, limiting the portability of digital video recorder (DVR) functionality and content availability across different devices and locations.
Innovation Solution
A USB dongle with virtual DVR software that connects to any media display device, allowing users to obtain media content from cloud servers, record, and store content independently of the service area, using a graphical user interface for authentication and control, and communicating with remote servers via the internet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video content providers use wired or wireless connections to send content to display devices in defined service areas, then content delivery is reliable and authorized, but media access is restricted to specific geographical locations and devices
Solution Approach 1:
The system separates authentication credentials from the service provider's infrastructure and places them on a portable USB dongle that can be moved between devices. This segmentation allows the authentication component to be independent from the service provider's location-based control, enabling portable access while maintaining authorization through the credential-based authentication mechanism.
Solution Approach 2:
The USB dongle acts as an intermediary carrier that holds authentication credentials. It mediates between the service provider's authorization system and the user's portable display devices, allowing authenticated access to be transferred across different devices and locations without requiring direct connection to the service provider's infrastructure.
2Ease of operation
If a digital video recorder is co-located with the display device, then recording functionality is integrated and reliable, but the system lacks flexibility and portability across different devices
Solution Approach 1:
The authentication and credential verification functionality is extracted from the service provider's fixed infrastructure and placed on a removable USB dongle. This extraction allows the recording system to maintain integrated functionality at each device while enabling easy portability by simply moving the dongle between different display devices.
Solution Approach 2:
The USB dongle serves as a universal authentication key that can be used with multiple different display devices and recording systems. This multi-functionality allows a single authentication credential to work across various devices, providing both integrated recording capability at each location and the flexibility to move between devices.
3Reliability
If video providers implement service area restrictions, then content protection and authorized access are maintained, but user access to content is limited by geographical location
Solution Approach 1:
The authentication credentials are copied onto a portable USB dongle that can be physically moved between different geographical locations and devices. This copying mechanism maintains content protection through secure credential storage while enabling geographical access flexibility by allowing the authenticated identity to be presented at any location with compatible playback equipment.

AI summary
Aspects of the subject disclosure may include, for example, a method including providing, by a processor in a dongle coupled to a display device, a graphical user interface at the display device, and transmitting a message to an authentication server in accordance with authentication information stored in a storage device of the dongle and an input via the graphical user interface. The method also includes obtaining an authentication confirmation; obtaining content from a content server; and recording the content in accordance with a second input via the graphical user interface. The recorded content is transmitted for storage at a storage server. The display device communicates with equipment of a video provider that is associated with a service area. In accordance with the authentication confirmation, the processor is authorized to obtain the content based on the location of the dongle relative to the service area. Other embodiments are disclosed.
