Centralized Content Selector Switch for Set-Top-Box-Free TV Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Frequent failures of TV set-top boxes and content streaming devices in multi-room, multi-unit facilities like hotels and office buildings result in increased costs and inconvenience, necessitating a centralized content distribution system that eliminates the need for additional intelligent hardware in each room.
Innovation Solution
A centralized content selector switch receives requests from remote control devices via a separate communication path, maps them to RF video channels, and delivers content directly to TVs without requiring additional devices, using a multicast network channel to RF video channel conversion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If set-top boxes and content streaming devices are deployed in each room, then content delivery capability is improved, but device complexity and maintenance costs increase
Solution Approach 1:
The patent extracts the intelligence and content selection capabilities from individual room devices (set-top boxes) and consolidates them into a centralized content selector switch. The remote control devices retain only basic control functions, while the centralized system handles content retrieval, channel mapping, and multicast distribution, thereby reducing device complexity in each room while maintaining content delivery capability.
Solution Approach 2:
The patent merges multiple individual content delivery systems into a single centralized content selector switch that serves the entire facility. By combining the functions of content selection, channel mapping, and distribution into one centralized device, the system reduces overall hardware complexity and eliminates the need for multiple intelligent set-top boxes across different rooms.
2Adaptability or versatility
If intelligent hardware is placed in each room, then content selection flexibility is improved, but reliability decreases due to frequent failures
Solution Approach 1:
The patent removes the unreliable intelligent hardware (set-top boxes) from individual rooms and extracts only the essential control functions to remote devices. The centralized content selector switch provides a single point of reliability while maintaining content selection flexibility through networked communication between remotes and the central system.
Solution Approach 2:
The patent introduces a centralized content selector switch as an intermediary between users and content distribution networks. This intermediary handles all content selection and delivery logic, providing a reliable single point of failure while maintaining user flexibility through remote control interfaces. The intermediary abstracts the complexity and reliability concerns from individual room devices.
3Ease of manufacture
If centralized content distribution is implemented, then maintenance costs are reduced, but communication pathway complexity increases
Solution Approach 1:
The patent makes the centralized content selector switch a universal device that handles multiple functions: content selection, channel mapping, multicast channel selection, and coordination with content distribution networks. By consolidating these diverse functions into a single multi-functional system, the patent reduces maintenance costs while managing communication complexity through a unified architecture.
Solution Approach 2:
The patent changes the communication model from individual room-based point-to-point connections to a centralized star topology with standardized protocols. The system uses multicast network channels and RF video channel mappings to simplify communication pathways, transforming complex individual device communications into standardized centralized control signals.
4Measurement precision
If remote control devices are mapped to specific RF channels, then content delivery accuracy is improved, but system complexity increases
Solution Approach 1:
The patent implements preliminary channel mapping between remote control devices and RF video channels before content delivery occurs. The centralized content selector switch maintains a pre-established mapping table that associates each remote device with its corresponding RF channel, enabling accurate content delivery without real-time complexity. This preliminary configuration simplifies the actual content delivery process.
Solution Approach 2:
The patent creates a virtual mapping layer that copies or replicates the relationship between remote control devices and RF channels through a standardized interface. The centralized system maintains copies of channel mapping information and uses these copies to route content accurately, thereby achieving precise content delivery while managing complexity through virtualization rather than physical reconfiguration.

AI summary
A content selector switch selects, based on a received request for content from a particular remote control device, a multicast network on which to provide the requested particular content. Each multicast network channel of the plurality of multicast network channels is mapped to a respective video channel and each remote control device in the facility (e.g., hotel) is mapped to a respective video channel that the TV controlled by the remote control device stays tuned to. The content selector switch performs the selection by identifying which remote control device in the facility sent the request and selecting the multicast network channel that is mapped to the RF video channel the identified remote control device is mapped to. The content selector switch then provides the specific content on the selected multicast network channel to a multicast-to-channel output device that provides the content on the RF video channel for the TV tuned to that RF video channel to display.
