VIDEO CALL METHOD AND RELATED DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240114110 titled 'VIDEO CALL METHOD AND RELATED DEVICE
Simplified Explanation
The patent application describes a method for switching a voice call task to a video call task when a device without a camera receives a video call request. The method involves establishing a voice call task with the caller, sending a probe frame to an external camera, and switching to a video call task once the external camera responds.
- First electronic device obtains a video call task request from a third electronic device
- First electronic device detects it has no camera
- First electronic device establishes a voice call task with the third electronic device
- First electronic device sends a probe frame to an external camera
- External camera powers on its communication module and approaches the first electronic device
- External camera obtains the probe frame and sends a response frame
- First electronic device switches the voice call task to a video call task
Potential Applications
This technology could be applied in situations where a device lacks a camera but needs to switch from a voice call to a video call seamlessly.
Problems Solved
This technology solves the problem of not being able to engage in video calls on devices without cameras.
Benefits
The main benefit of this technology is the ability to switch from a voice call to a video call even on devices without built-in cameras.
Potential Commercial Applications
One potential commercial application of this technology could be in smartphones or tablets that do not have front-facing cameras but still want to support video calling.
Possible Prior Art
There may be prior art related to methods for switching between voice and video calls on devices with limited hardware capabilities.
Unanswered Questions
How does the external camera communicate with the first electronic device?
The abstract does not provide details on the specific communication protocol or technology used for the external camera to send a response frame to the first electronic device.
What happens if the external camera is unable to respond to the probe frame?
The abstract does not mention any contingency plans in case the external camera fails to respond to the probe frame sent by the first electronic device.
Original Abstract Submitted
the method includes: a first electronic device obtains a video call task request sent by a third electronic device; the first electronic device detects that the first electronic device is currently configured with no camera; the first electronic device establishes a voice call task with the third electronic device; the first electronic device sends a probe frame to an external camera; a communication module in the external camera is powered on in a process in which the external camera approaches the first electronic device; the external camera obtains the probe frame; the external camera sends a response frame to the first electronic device; and the first electronic device switches the voice call task to a video call task.
