Problems solved by technology

Since the video display terminal only displays the captured video of the corresponding scene, its video playback and display method is relatively simple, and it cannot display the specific details in the video, so it is difficult to achieve the ideal playback effect
However, adding multiple close-up lenses to achieve close-up display of the video playback screen will increase the cost of video acquisition and playback, and the operation of multi-channel lens arrangement and switching is more complicated.

Abstract

An embodiment of the invention discloses a close-up display method and device based on a single-lens live video. The close-up display method provided by the embodiment of the invention comprises the steps of: determining a close-up region selected by a selection operation in response to the selection operation of a user on a display picture of video image data played in real time, and converting the video image data received in real time into first close-up video image data based on the close-up region and outputting the first close-up video image data to the video display terminal for display; or, sending a video acquisition instruction corresponding to the close-up region to the front end, receiving second close-up video image data acquired from the close-up region by the front end single lens correspondingly, and outputting the second close-up video image data to the video display end for display. By adopting the close-up display method, close-up display can be performed on the corresponding region of the live broadcast picture according to user selection, and the playing effect of the live broadcast video is optimized; and the acquisition and playing cost of close-up display ofthe live video is reduced through close-up display of the single-lens live video.

Description

technical field [0001] The embodiments of the present application relate to the technical field of video playback, and in particular to a close-up display method and device based on single-lens live video. Background technique [0002] The playback of high-definition video is generally displayed on the display screen after being decoded by the video decoding module. With the improvement of hardware and software performance such as shooting equipment, codec, and data transmission, the definition of corresponding video is getting higher and higher, such as 4K, 8K, 16K and above high-definition video resolution, which brings great advantages to the display of video details. Came for a better experience. Especially in scenarios such as live delivery with goods, video conferencing, live broadcast of events, and online classes, a better viewing experience can be provided through high-definition video capture and playback. [0003] However, when playing high-definition live video...
