Abstract

Disclosed is an audio-video data acquisition method. The method includes the following steps: recording first reference time when receiving a first instruction corresponding to video data acquisition; sending a second instruction corresponding to audio data acquisition; responding to the first instruction to acquire video data from the first reference time to preset time; receiving audio data corresponding to the second instruction; synchronously processing the video data and the audio data according to the preset time. The invention further discloses an audio-video data acquisition device. By the method and the device, the situation that sounds lag relatively to images in the process of video call can be prevented, and image and sound synchronization during video call is realized.

Description

technical field [0001] The invention relates to the field of audio and video collection, in particular to an audio and video data collection method and device. Background technique [0002] Traditional user equipment (for example, a digital television receiver or a computer) can implement the function of video calling. In the process of implementing the video call function, the user equipment generally collects video data and audio data respectively. Bluetooth headsets, mobile terminals and other devices are used to collect audio data, and the device that collects audio data communicates with the user device that collects video data in a wireless manner. [0003] In practice, the inventors found that the prior art has at least the following problems: [0004] There will be a time difference between the equipment that collects audio data and the user equipment that collects video data in the process of wireless communication, which will cause the image and sound in the vide...
