Display Apparatus Video Call Connection Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses, such as digital TVs, cannot efficiently receive and connect to video calls when turned off, leading to missed calls and unnecessary power consumption, as they require constant operation to handle incoming video communications.
Innovation Solution
A method and apparatus that include a communication module and controller in the display apparatus, allowing it to be turned on by an external device's control signal when a video call is received, enabling connection to the call and reducing power usage by only activating when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the display apparatus remains turned off to save power, then power consumption is reduced, but video calls cannot be received and connected
Solution Approach 1:
The display apparatus performs preliminary registration of identification information (phone number, email, or social network ID) for video calls before actually receiving a call. When a video call is received, the apparatus can quickly connect using pre-configured information without needing to be fully powered on beforehand, thus saving power while maintaining connectivity reliability
Solution Approach 2:
The communication module acts as an intermediary that can receive video call signals even when the main display apparatus is in a low-power state. The module receives the call signal and transmits it to the controller, which then activates the display apparatus to complete the connection, serving as a bridge between the low-power state and full operational state
2Reliability
If the display apparatus is constantly turned on to receive video calls, then video call connectivity is maintained, but power consumption increases
Solution Approach 1:
Instead of continuous operation, the display apparatus uses periodic action by activating only when needed. The communication module periodically checks for incoming calls while the main system remains in low-power mode. When a call is detected, the apparatus activates to complete the connection, then returns to low-power state after the call, creating a rhythm of activation that reduces overall power consumption while maintaining connectivity
Solution Approach 2:
The display apparatus serves itself by automatically activating in response to received video call signals without requiring manual user intervention. The controller monitors incoming signals and autonomously decides when to activate the display apparatus, managing its own power consumption based on actual usage needs rather than continuous operation
3Ease of operation
If the display apparatus automatically turns on when a video call is received, then connectivity is improved, but power consumption increases compared to staying off
Solution Approach 1:
The display apparatus performs self-service by automatically activating itself when a video call is received, eliminating the need for manual user intervention to turn on the device. The controller autonomously detects the incoming call signal and activates the display apparatus, making the connection process easier while minimizing power consumption by only activating when absolutely necessary

AI summary
Embodiments relates to a display apparatus that can perform a video call and a method of connecting to a video call thereof, in which the method includes: receiving a control signal from an external device where an identification information for a video call is registered when a video call is received; turning on the display apparatus in response to the received control signal; and connecting to the received video call.
