Document Type and Number:
WIPO Patent Application WO/2023/036258
Kind Code:
A1
Abstract:
Embodiments of the present invention disclose an unmanned aerial vehicle-based video live broadcast method, a system, a device and a storage medium. The method comprises: acquiring original video stream data sent by an unmanned aerial vehicle; encoding and decoding the original video stream data to obtain output buffer data; converting the output buffer data into a video frame supported by a WebRtc protocol; and sending the video frame to a preset server by means of a WebRtc transmission channel, so that the preset server performs live broadcast display according to the video frame. In the embodiments of the present invention, with the help of a terminal, data is transmitted by means of the WebRtc transmission channel, which reduces the delay of a live broadcast picture, and there is no need to provide a WebRtc conversion apparatus and a network communication apparatus on the unmanned aerial vehicle, which reduces hardware costs of the unmanned aerial vehicle. Moreover, a data conversion scheme carried out on the basis of the terminal has mature and easy-to-implement underlying architecture and low development costs. Existing unmanned aerial vehicle systems can be modified merely with the help of software modifications, which has a wide range of application scenarios.
