Camera method, display terminal, camera terminal and system in wireless live broadcast

Abstract

The invention discloses a shooting method, a display end, a camera end and a system in wireless live broadcast. The display end receives a video stream sent by the camera end through wireless communication and carries out live broadcast display on the video stream. The method comprises the following steps of responding to a shooting request and sending a shooting command to the camera end; receiving shooting time returned by the camera end through wireless communication, wherein the shooting time is recorded by the camera end when shooting operation is carried out according to the shooting command; and searching a video image matched with the shooting time from the video stream, carrying out screen shot operation when the video image is displayed in live broadcast and generating and displaying image preview. Through the technical scheme, the camera end does not need to carry out compressing on the image, so that the system resources of the camera end are saved; the transmission of theshooting time information occupies fewer wireless communication resources than the transmission of the image, so that the burden of the wireless communication can be reduced, and the increased delay of video stream transmission, which is caused by image transmission, is avoided.

Description

technical field [0001] The present invention relates to the technical field of wireless live broadcasting, in particular to a camera method, a display terminal, a camera end and a wireless live broadcasting system in wireless live broadcasting. Background technique [0002] Many devices that wirelessly transmit video have a camera function, such as webcasts, drones, monitors, etc. Different from the transmission of wired video, the transmission of wireless video stream will have a delay, as small as 300 milliseconds, as large as a few seconds, such a delay will cause differences between the content collected by the camera end and the content obtained and displayed by the display end. It will affect the immediacy of live video, especially when taking pictures, the impact of this difference is more significant. [0003] This is because, when the user uses the camera function, in order to ensure the content that the user wants when taking a photo, after taking a photo, the ima...

AI Technical Summary

Problems solved by technology

This process includes two processes of compressing pictures and transmitting pictures. If the resolution of the camera end is very large, such as 4K or 2K, the resources of the camera end will be consumed for processing when running the image compression algorithm. The communication part increases the burden, making the delay of video stream transmission longer, the above-mentioned difference is more obvious, and it affects the immediacy of live video broadcasting
