Abstract

The invention discloses a video recording method capable of achieving audio-video synchronization and display equipment. A camera collects an action picture that a user presents a corresponding actionalong with a demonstration action displayed in a display; in response to the video recording starting instruction, the controller acquires preset human limb reaction time, preset image transmission time, image algorithm processing time and optimal delay time of the camera in recording a first frame of action picture, and calculates the total video delay duration of video recording; the playing timestamp value of each frame of action picture is modified according to the total video delay duration to obtain a new playing timestamp value; and a video file with synchronized audio and video is synthesized according to the background audio and the action picture corresponding to each new playing timestamp value. Visibly, according to the method and the display equipment provided by the invention, by modifying the playing timestamp value of each frame of action picture and compensating the time difference between the recorded audio and the recorded video, the action picture corresponding tothe background audio and the action picture corresponding to the new playing timestamp value are synthesized to obtain the audio and video synchronous video file.

Description

technical field [0001] The present application relates to the technical field of smart TVs, in particular to a video recording method and a display device for synchronizing audio and video. Background technique [0002] With the continuous development of communication technology, terminal devices such as computers, smart phones, and display devices have become more and more popular. Display devices, such as smart TVs, have gradually entered people's lives and brought entertainment experience to people. In order to provide a rich functional experience, application programs that can implement various functions are installed in the display device. [0003] Currently, a display device may provide a video recording function. Specifically, a camera is configured in the display device, and images are collected by the camera, and a demonstration video is played on the display, and the demonstration video includes demonstration actions and background audio. During video recording, ...
