Embodiment 1

[0044] Such as figure 1As shown, the present invention provides a data transmission method for live video broadcasting. Generally, the video data and audio data collected at the same time at each time point are different in size. Taking 1s as the time node as an example, the audio data collected is larger than the audio data. , in the prior art, in order to realize the synchronization of video data and audio data, the collected audio data and video data are generally encoded and then packaged together for transmission, which leads to the fact that the data packet is too large and the data transmitted each time The amount is very large, which may result in failure to transmit.

[0045] The main reason is that the size of the video data and the audio data are different, resulting in different encoding time. The synchronization is achieved by packaging, which also increases the time and difficulty of packaging.

[0046] In this embodiment, since there is no direct relationship b...

Embodiment 2

[0060] Such as figure 2 As shown, in step 100, when collecting the original audio and video data, the type of the audio data is divided into a computer audio signal and a microphone audio signal according to the source and collected respectively; the type of the video data is divided into a camera video signal and a computer audio signal according to the source. The screen signal is collected.

[0061] The computer audio signal, microphone audio signal, camera video signal and computer screen signal decoded by the decoding unit are matched and distributed according to all marker points of the same group, the computer audio signal and the microphone audio signal are played synchronously, and the camera video signal The computer screen signal and the computer audio signal and the microphone audio signal are respectively matched and played synchronously.

[0062] There are two live video modes formed by camera video signals and computer screen signals in this embodiment, specif...

Embodiment 3

[0076] Such as image 3 As shown, according to the data transmission method of the above-mentioned live video system, the present invention also provides a data transmission device for live video, including a live terminal 1, a cloud service platform 2 and a playback terminal 3, and the live terminal 1 passes through an audio and video acquisition unit 4 Gather the original audio and video data of the live broadcast terminal, the live broadcast information of the live broadcast terminal 1 carries out information processing through the cloud service platform 2, and the information resources after processing are displayed at the playback terminal 3, and the multi-channel video live broadcast system of the present invention also has a cloud storage function, so Users can record and save the live broadcast content in the cloud storage space, so that users who missed the live broadcast can watch it again through this function to improve the user experience.

[0077] The original au...

Abstract

The embodiment of the present invention discloses a data transmission method and transmission device for live video broadcasting, including the following steps: continuously collect the original audio and video data of the live broadcast terminal in real time; classify and package the original audio and video data into audio data and video data sequentially on time, and audio The respective data chains of data and video data are marked as two groups according to the same position marks, and a fixed-length and blank buffer data chain is added to the beginning of the audio data data chain to obtain the target audio data; the video data corresponds to the target audio data The target video data is re-marked; the target audio and video data are respectively compressed and pushed to the playback end through their own independent encoding units; the playback end decodes the target audio and video data respectively, and matches the target audio data and target video data according to the marking points For playback, this solution classifies audio signals and video signals to ensure the normal broadcast of video programs, improve fault tolerance and intelligent scheduling.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of video live broadcast systems, and in particular to a data transmission method and transmission device for video live broadcast. Background technique [0002] With the continuous improvement of mobile communication network and mobile terminal technology, mobile live video broadcasting has begun to enter all aspects of social life, and mobile education of video live broadcasting technology has attracted people's attention. For example, teachers and students use mobile terminals to realize an environment where they can conduct live teaching and watch live courses anytime and anywhere through the mobile video live broadcast system. The combination of mobile technology and education plays an important role in the lifelong education. The current multi-channel video live broadcast system transforms the traditional live broadcast into a new media interaction mode, and the identities of the ...
