Centralized Content Switching for Set-Top-Box-Free TV Distribution

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 multicast network channels, and delivers content directly to TVs without requiring additional devices by using a multicast-to-RF video channel conversion system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If set-top boxes and content streaming devices are deployed in each room, then content delivery capability is improved, but device reliability deteriorates due to frequent failures

Engineering Contradiction:

Improvecontent delivery capabilityVSAvoiddevice reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent extracts the intelligence and content selection capability from individual room devices (set-top boxes) and concentrates it in a centralized headend system. The remote control devices become simple transmitters of selection signals, while the complex content retrieval and delivery logic resides centrally, eliminating the need for intelligent hardware in each room.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The centralized content selector switch serves multiple rooms and multiple content sources through a single device. It handles content selection requests from any remote control device, retrieves content from various sources (cable, satellite, streaming), and distributes it to multiple TVs simultaneously through the RF video distribution network.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If intelligent hardware is installed in each room, then content selection functionality is improved, but device complexity increases

Engineering Contradiction:

Improvecontent selection functionalityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the intelligence and content selection capability from individual room devices (set-top boxes) and concentrates it in a centralized headend system. The remote control devices become simple transmitters of selection signals, while the complex content retrieval and delivery logic resides centrally, eliminating the need for intelligent hardware in each room.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent merges multiple functions (content selection, content retrieval, channel mapping, and distribution control) into a single centralized content selector switch at the headend. This consolidation eliminates the need for separate intelligent devices in each room, reducing overall system complexity while maintaining full functionality.

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If set-top boxes are deployed in each room, then content delivery is enabled, but maintenance costs increase

Engineering Contradiction:

Improvecontent deliveryVSAvoidmaintenance costs

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent extracts the intelligence and content selection capability from individual room devices (set-top boxes) and concentrates it in a centralized headend system. The remote control devices become simple transmitters of selection signals, while the complex content retrieval and delivery logic resides centrally, eliminating the need for intelligent hardware in each room.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces expensive, complex set-top boxes with simple, inexpensive remote control devices that lack intelligent hardware. These simplified remotes are much cheaper to manufacture and maintain, and their simplicity means they have fewer components that can fail, effectively making them disposable or easily replaceable.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

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.
