Display Device Automatic Video Call Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for establishing video calls require user intervention, making the process inconvenient, especially when trying to connect a mobile terminal with a display device.
Innovation Solution
A display device with a camera and processor that automatically establishes a video call process upon receiving a push message from a server, presenting a window for the counterpart and rejecting the call if the mobile terminal is not authorized, thereby simplifying the video call initiation without user operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic video call establishment is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary authorization between the mobile terminal and display device before the video call is initiated. The mobile terminal sends an authorization request to the display device, and the display device stores the authorization status. When a video call request arrives, the system automatically checks the pre-stored authorization status to determine whether to establish the call, eliminating the need for real-time user confirmation.
Solution Approach 2:
The display device automatically processes video call requests by itself without requiring user intervention. It autonomously checks authorization status, determines whether to accept or reject the call, and establishes or terminates the video call connection automatically. The system serves itself by using pre-stored authorization information to make decisions, reducing the need for external user control.
2Reliability
If user operation is required for video call setup, then device security is improved, but ease of operation deteriorates
Solution Approach 1:
Authorization is performed in advance before the video call is initiated. The mobile terminal sends an authorization request to the display device, which stores the authorization status. When a video call request arrives, the system automatically checks the pre-stored authorization status, ensuring security is maintained while eliminating the need for real-time user confirmation.
Solution Approach 2:
The display device provides feedback to the mobile terminal about the authorization status. When a video call request is received, the display device checks the stored authorization information and automatically responds with acceptance or rejection, providing immediate feedback without requiring user intervention while maintaining security through pre-established authorization rules.

AI summary
Disclosed are a method of performing video call and a display device. The display device includes: a camera; a display, configured to present a window for a counterpart and/or a local window; and a processor, configured to: receive a push message sent from a server, wherein the push message is sent after the server receives a video call request sent from the mobile terminal; automatically establish a call process, and control the display to present the window for the counterpart and not to present the local window in response to the push message when the mobile terminal is authorized by the display device; and reject the video call request in response to the push message when the mobile terminal is not authorized by the display device.
