Embodiment 1

[0018] The present application provides an audio-video synthesis method, and the method can be applied in an audio-video synthesis system. Wherein, the audio-video synthesis system can be deployed on a cloud server, and the server can be an independent server or a distributed server cluster, and specifically can be flexibly configured according to required computing resources. see figure 1 , the audio-video synthesis system can perform data interaction with the director client and the user client. Wherein, the broadcast guide client may be an instruction issuing party for audio and video synthesis. The user client may be a terminal device used by the user, and the synthesized video picture and audio information may be played on the terminal device. Of course, in practical applications, the server of the live broadcast platform or the video-on-demand platform may also be included between the cloud server and the user client. The synthesized audio and video output stream can ...

Embodiment 2

[0050] The present application also provides an audio and video synthesis system, which can be deployed in a cloud server. see Figure 5 , the system includes an instruction control module, a data stream synthesis processing module, a data stream multi-version encoding module, and a data confluence output module, wherein:

[0051] The instruction control module is used to receive video synthesis instructions and audio synthesis instructions sent by the broadcast guide client;

[0052] In this embodiment, the data stream synthesis processing module may include a video picture synthesis processing module and an audio effect synthesis processing module; the data stream multi-version encoding module may include a video multi-version encoding module and an audio multi-version encoding module.

[0053] The video picture synthesis processing module is used to synthesize a first video stream based on multiple video input streams, and synthesize a second video stream based on the mult...

Abstract

The invention discloses an audio and video synthesis method and an audio and video synthesis system. The method comprises the steps of receiving a video synthesis command sent by a director client, synthesizing a first video stream based on a plurality of video input streams, and synthesizing a second video stream based on the plurality of video streams and the first video stream; receiving an audio synthesis command sent by the director client, and separately synthesizing a first audio stream and a second audio stream based on a plurality of audio input streams; separately coding the audio and video streams to acquire a first corresponding video coded stream set, a second corresponding video coded stream set, a first corresponding audio coded stream set and a second corresponding audio coded stream set; and acquiring a first output stream and a second output stream based on integration of the coded stream sets, and separately providing the first output stream and the second output stream to a user client and the director client. According to the technical scheme provided by the invention, the cost during an audio and video synthesis process can be reduced.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to an audio and video synthesis method and system. Background technique [0002] In some current application scenarios, it is usually necessary to integrate multiple channels of audio and video signals, so that the pictures of multiple channels of audio and video signals can be displayed in the same video picture. For example, in the process of video conferencing and TV station broadcasting, it is usually necessary to collect audio and video signals from multiple angles and scenes, and then according to the preset method or the control of the broadcasting director, the collected audio and video signals are combined according to the required picture and The sound effects are synthesized, and finally the synthesized audio and video signals can be provided to the user for viewing. [0003] However, this traditional way of audio and video synthesis usually requires more expensive ...
