Linkage Viewing Between Mobile Phone and Digital TV
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience and time consumption when trying to seamlessly switch from watching a TV broadcasting program on a cellular phone to a digital TV, as there is no control means for intercommunication between devices, requiring manual channel selection and power management.
Innovation Solution
A method and apparatus for linkage viewing between a mobile communication apparatus and a digital TV, where a TV linkage-viewing command is input to transmit data information to select and change channels on both devices, allowing seamless continuation of the program without user-specific manipulation, using dedicated buttons or existing controls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is used to switch from mobile communication apparatus to digital TV, then the user can control the TV, but the operation becomes time-consuming and inconvenient
Solution Approach 1:
The system performs preliminary actions by automatically transmitting channel information from the mobile communication apparatus to the digital TV before the user needs to watch. The TV is pre-configured with the correct channel, so when the user activates the linkage function, the switching occurs immediately without manual channel searching.
Solution Approach 2:
A control unit acts as an intermediary between the mobile communication apparatus and the digital TV. This intermediary automatically transmits channel information and controls the TV based on the mobile device's current channel, eliminating the need for manual operation while enabling seamless transition between devices.
2Ease of operation
If the digital TV is turned on manually, then the TV can be used, but the power management becomes inconvenient and time-consuming
Solution Approach 1:
The system performs preliminary action by turning on the digital TV automatically before the user needs to watch. When the mobile communication apparatus detects that the TV is off, it automatically transmits a power-on command, so the TV is ready when the user initiates the linkage viewing.
Solution Approach 2:
The system provides self-service by enabling the mobile communication apparatus to automatically control the digital TV's power state. The mobile device sends commands to turn the TV on or off based on the user's viewing intentions, eliminating the need for manual power management.
3Reliability
If the user manually searches for the channel, then the TV can display the program, but the user may miss part of the program due to time delay
Solution Approach 1:
The system performs preliminary action by automatically transmitting the current channel information from the mobile communication apparatus to the digital TV before the user needs to switch devices. This ensures the TV is already tuned to the correct channel when the user arrives, preventing any program content from being missed.
Solution Approach 2:
The system uses feedback by continuously monitoring the mobile communication apparatus's current channel and automatically adjusting the digital TV's channel to match. This real-time feedback mechanism ensures the TV always displays the correct program without requiring manual intervention or causing time delays.

AI summary
A method of linkage-viewing a TV broadcasting program between a mobile communication apparatus and a digital TV, the method includes inputting a TV linkage-viewing command in order to successively view a TV broadcasting program which is being viewed on the mobile communication apparatus, on the digital TV; transmitting data information from the mobile communication apparatus to the digital TV according to the input of the TV linkage viewing command; and selecting a TV channel in the digital TV which is the same as a current channel which is being viewed on the mobile communication apparatus and changing to the selected TV channel based on the data information which the digital TV has received.
