Wireless Screen Sharing Device Video Transmission via Client Decoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless screen sharing devices without video decoding capabilities cannot properly play compressed and encoded video streams, leading to conferencing software on computers being unable to play the video streams normally.
Innovation Solution
A method that allows wireless screen sharing devices without video decoding capabilities to connect to a client device, identify if a decoding application is running, and then transmit video data in a format that can be processed by the client device's decoding application, ensuring normal playback in conferencing software.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If wireless screen sharing device transmits compressed and encoded video stream without video decoding capability, then device complexity is reduced, but conferencing software cannot play the video stream normally
Solution Approach 1:
The patent introduces a client device with decoding application as an intermediary between the wireless screen sharing device and the conferencing software. The wireless screen sharing device transmits compressed video streams to the client device, which decodes them and makes them available to conferencing software through a camera peripheral interface, thus resolving the incompatibility without adding decoding capability to the wireless screen sharing device itself
Solution Approach 2:
The system separates the video transmission function (performed by the wireless screen sharing device) from the video decoding function (performed by the client device's decoding application). This segmentation allows each component to specialize in its strength while working together through standardized interfaces
2Adaptability or versatility
If wireless screen sharing device is connected to screen sharing receiving device to capture camera head video, then adaptability is improved, but video data format compatibility deteriorates
Solution Approach 1:
The decoding application on the client device dynamically adjusts video data format parameters based on the capabilities of the conferencing software and the transmission capabilities of the wireless screen sharing device, converting between different video formats to ensure compatibility across the system

AI summary
The present disclosure discloses a video transmission method, a conferencing system, and a storage medium. The video transmission method is applied to a wireless screen sharing device including a universal interface, wherein the wireless screen sharing device does not have video decoding capability, the wireless screen sharing device is connected to a screen sharing receiving device, and the method includes: connecting with the client device through the universal interface; configuring the universal interface to create a camera peripheral device; when it is recognized that a decoding application is running, transmitting first notification information to the screen sharing receiving device; transmitting the video data in the first data format to the decoding application; presenting the video data in the second data format to the conferencing software through the camera peripheral device; when it is recognized that the decoding application is not run, transmitting second notification information to the screen sharing receiving device; and transmitting the video data in the third data format to the conferencing software through the camera peripheral device, so to enable conferencing software of the client device to play the video data in the second format normally.
