Multimedia Device Unified Remote Control via Automatic Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multimedia devices require multiple remote controllers to control various connected devices, and the control mode of a remote controller must be manually changed and set for each device, leading to user inconvenience.
Innovation Solution
A multimedia device with an external device interface module, network interface module, display module, and user interface module that automatically sets and changes the remote controller's control mode based on the connected external device's status and user input, allowing for unified control of multiple devices using a single remote controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple remote controllers are provided for different external devices, then each device can be controlled independently, but the device complexity and number of controllers increases
Solution Approach 1:
The patent implements a universal remote controller that can control multiple types of external devices (TV, audio player, DVD player, BD player, HTS, etc.) through a single device. The controller includes a learning function that allows it to store and reproduce control signals for different devices, enabling one remote to perform multiple control functions without requiring separate remotes for each device type.
Solution Approach 2:
The remote controller uses a learning mechanism to copy control signals from different external devices. When a user presses a button on the remote, the controller learns the corresponding signal pattern and stores it, allowing the same physical button to control different devices by reproducing the appropriate learned signal. This copying approach enables versatility without requiring device-specific remotes.
2Reliability
If control mode is manually changed for each external device, then accurate control can be achieved, but the ease of operation decreases due to frequent manual settings
Solution Approach 1:
The patent implements automatic mode setting that occurs before the user needs to control an external device. When the multimedia device detects which external device is connected (e.g., through HDMI-CEC or network identification), it automatically configures the remote controller's operating mode to match the connected device type. This preliminary automatic configuration eliminates the need for manual mode changing while ensuring accurate control signals are transmitted.
Solution Approach 2:
The system uses feedback from the multimedia device about which external device is currently connected to automatically adjust the remote controller's behavior. The controller receives information about the connected device status and automatically switches its control signal output accordingly, creating a closed-loop system that maintains accurate control without requiring user intervention.
3Reliability
If control mode is set through several depths, then precise device control is achieved, but the ease of operation decreases due to complex settings
Solution Approach 1:
The patent implements automatic mode setting that occurs before the user needs to control an external device. When the multimedia device detects which external device is connected (e.g., through HDMI-CEC or network identification), it automatically configures the remote controller's operating mode to match the connected device type. This preliminary automatic configuration eliminates the need for manual mode changing while ensuring accurate control signals are transmitted.
