Remote Control Device Configuration via HDMI CEC
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices require manual programming or the use of universal remote controls to control multiple devices, which can be inconvenient and inefficient.
Innovation Solution
Implementing a system that uses a device-to-device communication protocol, such as HDMI CEC, to enable one device to configure and control other devices on a customer premises, allowing remote control commands to be shared and executed across connected devices without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual programming or universal remote controls are used to control multiple devices, then device control capability is improved, but operation complexity and time consumption increase
Solution Approach 1:
The system performs preliminary actions by automatically discovering devices and pre-configuring control relationships during system initialization or when devices are added to the network. The controller proactively sends configuration data to controlled devices before user operation is needed, eliminating the need for manual programming at the time of use.
Solution Approach 2:
The system enables devices to self-configure through automatic device discovery and peer-to-peer communication. When a new device is added to the network, it automatically announces its presence and receives control configuration data from the controller without requiring user intervention, making the system self-sufficient in the configuration process.
2Measurement precision
If manual programming is used to configure devices, then control precision is improved, but ease of operation deteriorates
Solution Approach 1:
Devices automatically perform self-configuration by discovering other devices on the network and establishing control relationships autonomously. The system extracts device identifiers and control mappings through automatic communication protocols, eliminating the need for users to manually program control relationships while maintaining accurate device-to-remote-control mappings.
Solution Approach 2:
The system implements feedback mechanisms where devices automatically verify and confirm their control relationships through bidirectional communication. The controller sends configuration data to controlled devices, which acknowledge receipt and verify proper configuration, ensuring control mapping accuracy without user intervention.
3Extent of automation
If device-to-device communication protocols are implemented, then automation level is improved, but device complexity increases
Solution Approach 1:
The system employs a universal communication protocol based on standard network protocols (such as TCP/IP and HTTP) that can be implemented across multiple device types and manufacturers. This universal approach allows diverse devices to communicate through common interfaces, reducing individual device complexity while enabling sophisticated automated configuration capabilities.
Solution Approach 2:
The controller acts as an intermediary that manages the complex communication protocols and automatically distributes control configuration data to controlled devices. By centralizing protocol management in the controller, individual controlled devices can remain simpler while still benefiting from automated configuration through the intermediary's coordination.

AI summary
A particular device may configure one or more of other devices to accept and execute remote control commands from the particular device's remote control unit. This may be performed via one or more various communication links between the devices on that enables the devices to communicate with each other. For example, the remote control of a set-top box can be used to control both the set-top box and a television without a user having to specially program the set-top box or other universal remote control. One example of a communication link between the devices that enables the devices to communicate with each other is a device-to-device messaging protocol such as that provided by the High Definition Multimedia Interface (HDMI) standard.
