Wireless Terminal Controlling External Device Broadcast Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users experience inconvenience when transitioning from watching or listening to TV/radio on a wireless terminal's DMB or radio function outside the house to a TV/stereo system inside, as they need to terminate the wireless terminal's function and manually find the same broadcast on the external device.
Innovation Solution
A wireless terminal with the capability to control external devices like TVs or stereos, allowing seamless switching of broadcasts by displaying dedicated icons for automatic power-on and channel shifting, enabling remote control operations via wireless communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user manually switches from wireless terminal broadcast mode to external device, then the external device can output the broadcast, but the user experiences interruption and inconvenience in finding the same broadcast channel
Solution Approach 1:
The wireless terminal stores channel correspondence information between its own channels and external device channels in advance. When switching devices, the terminal automatically transmits the appropriate command to tune the external device to the corresponding channel, eliminating the need for manual channel searching and reducing switching time.
2Ease of operation
If the wireless terminal automatically controls the external device to output the same broadcast, then user convenience is enhanced, but the device complexity increases
Solution Approach 1:
The wireless terminal acts as an intermediary between the user and the external device. It stores pre-configured channel correspondence information and automatically transmits control commands to the external device, simplifying the user interface while managing the complexity internally through stored correspondence data.
3Reliability
If the wireless terminal transmits control commands to the external device, then seamless broadcast switching is achieved, but additional communication protocols and control mechanisms are required
Solution Approach 1:
The wireless terminal utilizes existing universal control protocols (such as infrared or wireless communication protocols commonly used for remote control) to transmit commands to the external device. This approach maintains reliability for uninterrupted broadcast switching while avoiding the need to develop proprietary complex communication protocols, as it leverages established multi-functional control standards.

AI summary
Provided is a wireless terminal and method therefor, configured to play a broadcast program (TV and/or radio) in a broadcast mode thereof. A display unit displays, during the broadcast mode, at least one icon dedicated to automatically controlling an external device to output the same broadcast as that of a current channel in the broadcast mode. A controller is configured to detect selection of the at least one icon and in response, to transmit via a wireless communication unit at least one command to the external device to automatically tune to a corresponding channel of the current channel and output the same broadcast thereof. The external control by the wireless terminal can enable uninterrupted switching of the broadcast from the wireless terminal to the external device.
