Enhanced Set-Top Box Switching for Legacy Service Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Service providers face challenges in delivering multiple services, such as ultra high definition television (UHDTV) and legacy content, as subscriber devices often require manual switching and are not configured to handle both types of content simultaneously, limiting user experience.
Innovation Solution
A system comprising an enhanced set-top box (STB) with a switching element that automatically switches between external and internal inputs based on content type requests, allowing seamless delivery of both legacy and enhanced services through different STBs, using an HDMI switch and remote control integration for unified user control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a new subscriber device is used to receive a new service (e.g., UHDTV), then the new service can be received, but the legacy service cannot be received due to device limitations
Solution Approach 1:
The patent combines multiple set-top boxes (legacy STB and enhanced STB) into a unified system where the enhanced STB acts as a parent device that can receive and switch between both legacy and enhanced services. This merging allows the system to access multiple service types without requiring the subscriber to manually connect different devices to the display device.
Solution Approach 2:
The enhanced STB is designed with multi-functionality to handle both legacy services (through the legacy STB connection) and enhanced services (natively). The device includes a switching element that can route signals from either the legacy STB or internal enhanced service sources to the display device, making it a universal receiver for multiple service types.
2Adaptability or versatility
If multiple subscriber devices are used to receive both new and legacy services, then service variety is improved, but user operation becomes complex due to manual device switching
Solution Approach 1:
The system implements self-service through automatic service detection and switching. The enhanced STB automatically detects which service type is being provided (legacy or enhanced) and autonomously switches its input source accordingly, eliminating the need for the subscriber to manually connect and disconnect devices based on service type.
Solution Approach 2:
The system uses feedback mechanisms where the enhanced STB monitors service signals and automatically adjusts its switching element based on detected service types. This feedback loop enables the device to respond dynamically to service changes without user intervention, maintaining ease of operation while supporting service variety.
3Manufacturing precision
If a subscriber device is configured for enhanced service (e.g., UHDTV), then enhanced content quality is improved, but legacy content compatibility is lost
Solution Approach 1:
The system segments the content reception function by separating legacy service reception (handled by the legacy STB) from enhanced service reception (handled by the enhanced STB). This segmentation allows each component to be optimized for its specific function while the enhanced STB's switching element integrates both streams, enabling the system to deliver high-quality enhanced content while maintaining legacy content compatibility.

AI summary
Methods, systems, and computer readable media may be operable to facilitate the coordination of multiple devices to provide multiple services. A legacy set-top box (STB) configured to provide legacy services may be connected to an enhanced STB that is configured to provide enhanced services. The enhanced STB may include a switch that is configured to switch a content input source between the legacy STB and the enhanced STB. The legacy STB may receive user requests for content, and based on the type of content requested, the legacy STB may output a signal to the enhanced STB directing that the input source be switched according to the type of content requested. A user interface output from the legacy STB may provide a user with one or more menu items for requesting a legacy service or enhanced service.
