Remote Video Call Access with Direct Camera-to-Server Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Employees experience difficulties in transmitting and receiving video call data remotely due to network delays and screen freezing issues when accessing company devices from home, which are managed under the company's security system.
Innovation Solution
An electronic device equipped with a camera, communication interface, and display, along with processors, enables remote access to another device's video call application by capturing images through its own camera, transmitting them to a server, and displaying the remote device's screen, including a video call image, while managing network connections to optimize data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If video call data is relayed through the in-office electronic device, then the employee can perform video calls from remote location, but network delays and screen freezing occur due to large data size transmission
Solution Approach 1:
The patent segments the video call data transmission path into two parts: control signals and session information are transmitted through the remote access connection to the in-office device, while actual video data is transmitted directly between the remote device and the video call server. This segmentation reduces the data burden on the remote access connection, eliminating screen freezing and delays while maintaining remote video call capability.
2Adaptability or versatility
If the employee uses home electronic device to access in-office device, then remote work is enabled, but data transmission efficiency decreases due to network relay
Solution Approach 1:
The patent introduces the video call server as an intermediary that directly receives video data from the remote device. The in-office device acts only as a mediator for establishing the video call session, not for transmitting video data. This intermediary approach enables remote work flexibility while achieving direct high-speed video data transmission between the remote device and server.
3Ease of operation
If video call application is executed in the remote device through remote access, then seamless remote access is achieved, but network bandwidth is consumed by relaying large video data
Solution Approach 1:
The patent extracts the video data transmission function from the remote access connection and establishes a separate direct connection between the remote device and video call server. Only control signals and session information are transmitted through the remote access connection, while video data is transmitted separately. This extraction enables seamless remote application execution while dramatically reducing network bandwidth consumption on the remote access connection.

AI summary
An electronic device performing a remote access function to other electronic devices and a controlling method thereof are provided. The electronic device according to an embodiment includes a communication interface, a camera, a display, and one or more processors configured to, in response to a video call application being executed in a first external electronic device remotely connected through the communication interface, receive a request for providing connection information of the camera to capture an image related to the video call application from the first external electronic device, transmit the connection information of the camera obtained in response to the request to the first external electronic device, and based on communication being established with a server device providing a video call service of the video call application based on the connection information of the camera transmitted to the first external electronic device, transmit an image captured through the camera to the server device through the communication interface.
