Problems solved by technology

[0002] Since the audio data packet is smaller than the video data packet, the transmission speed of the audio data packet is greater than the transmission speed of the video data packet during the transmission of audio and video from the Internet of Vision terminal to the Internet terminal, resulting in peer-to-peer communication between the Internet of Vision terminal and the Internet terminal. During a video phone call or a video conference, the audio data collected by the video network terminal will be transmitted to the Internet terminal earlier than the video data collected at the same time, which will cause the delay phenomenon that the picture viewed on the Internet terminal is slower than the sound heard

Embodiment Construction

[0071] In order to make the above purpose, features and advantages of the present application more obvious and understandable, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0072] The Internet of Vision is an important milestone in the development of the network. It is a real-time network that can realize real-time transmission of high-definition video, and push many Internet applications to high-definition video, high-definition face-to-face.

[0073] The Internet of View adopts real-time high-definition video exchange technology, which can provide required services on one network platform, such as high-definition video conferencing, video surveillance, intelligent monitoring and analysis, emergency command, digital broadcast TV, time-lapse TV, online teaching, live broadcast , VOD on demand, TV mail, personalized recording (PVR), intranet (self-managed) channel, intelligent video bro...

Abstract

The invention provides an audio and video synchronization method, an audio and video synchronization system, equipment and a storage medium. The method is applied to the audio and video synchronization system. The audio and video synchronization system comprises a protocol conversion server. The protocol conversion server virtualizes an articulated naturality web virtual terminal comprising an articulated naturality web module, an audio and video synchronization module and a real-time transmission module; By comparing the audio coding timestamp with the system timestamp and a video encoding timestamp with a system timestamp on the audio and video synchronization module, the articulated naturality web module controls the opportunity of sending the audio bare stream data packet and the videobare stream data packet to a real-time transmission module according to the comparison result, so that the synchronization of the audio and the video in the articulated naturality web transmission process is realized, and the delay phenomenon that a watched picture is slower than heard sound does not occur in the Internet terminal any more.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to an audio-video synchronization method, audio-video synchronization system, device and storage medium. Background technique [0002] Since the audio data packet is smaller than the video data packet, the transmission speed of the audio data packet is greater than the transmission speed of the video data packet during the transmission of audio and video from the Internet of Vision terminal to the Internet terminal, resulting in peer-to-peer communication between the Internet of Vision terminal and the Internet terminal. During a video phone call or a video conference, the audio data collected by the video network terminal will be transmitted to the Internet terminal earlier than the video data collected at the same time, which will cause the delay phenomenon that the picture viewed on the Internet terminal is slower than the sound heard.
