Embodiment 1

[0043] Such as figure 1 and figure 2 As shown, the present invention provides a live video system based on hybrid cloud storage, including a live broadcast terminal 1, a cloud service platform 2 and a playback terminal 3.

[0044] The working process of the video live broadcast system in this embodiment is specifically that the live broadcast terminal 1 collects the original audio and video data of the live broadcast terminal through the audio and video acquisition unit 4, and the live broadcast information of the live broadcast terminal 1 is processed by the cloud service platform 2, and the processed information resources It is shown on the playback terminal 3 that the cloud service platform 2 not only has audio and video data processing functions, but also has a cloud storage function, so users can record and save live content in the cloud storage space, so that users who miss the live broadcast can watch it again through this function , improve user experience.

[0045]...

Embodiment 2

[0058] Such as figure 1 As shown, the cloud service platform 2 of the present embodiment also has:

[0059] The audio and video asynchronous subpackaging unit 201 is used to extract several marking points from the common data chain of the original audio and video data and then classify and package them into audio data and video data. The marking points correspond to the respective data chains of the audio data and video data Mark points above are recorded as the same group;

[0060] The preprocessing unit 202 is used to correct the audio data, and add a fixed-length and blank buffer data chain at the beginning of the data chain of the audio data, then correct the video data, and re-match the respective Marking point information of the same group on the data link;

[0061] Encoding unit 203 pushes the audio data and video data processed by the preprocessing unit 202 to the playback terminal 3 through the independent encoding unit 203 respectively to compress the data chain. ...

Embodiment 3

[0072] Such as image 3 As shown, in order to assist in explaining the working mode of the video live broadcast system, the present invention also provides a signal processing method of a video live broadcast system based on hybrid cloud storage, including the following steps:

[0073] Step 100, collect the original audio and video data of the live broadcast terminal in real time, and push the original audio and video data to the cloud service platform. The source of the original audio data is mainly the human voice signal collected by the microphone and the audio signal of the computer. The source of the original video data is mainly the camera Video signal and computer screen signal.

[0074]Step 200, asynchronously pack the audio and video data, and synchronously match the audio and video data at the playback end;

[0075] The specific steps for matching and playing audio data and video data are as follows:

[0076] Step 201, sequentially extract a mark point on the commo...

Abstract

The embodiment of the invention discloses a video live broadcast system based on hybrid cloud storage and a signal processing method thereof. The system comprises a live broadcast end, a cloud serviceplatform and a playing end. The live broadcast end collects the original audio and video data through the audio and video collection unit, the original audio and video data is processed by the cloudservice platform and is transmitted to the playing end for display; the cloud service platform comprises a public cloud unit and a private cloud unit which establish communication transmission with each other, the public cloud unit is used as a common service for uploading data by the playing end and the live broadcast end, the public cloud unit comprises a shared cloud storage unit and a storagetime management unit, the shared cloud storage unit stores the live broadcast resources, and the storage time management unit deletes the data in the shared cloud storage unit on time. According to the scheme, through the mode of sharing the storage space, the full utilization of the storage space is guaranteed, the utilization rate of the storage space is improved, meanwhile, it is guaranteed that the resource storage requests of all users are responded in time, and the storage space leasing cost is reduced.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of live video system, and in particular to a live video system based on hybrid cloud storage and a signal processing method thereof. Background technique [0002] With the continuous improvement of mobile communication network and mobile terminal technology, mobile video broadcasting has begun to enter all aspects of social life, and the mobile education of video 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. Combining mobile technology with education plays an important role in 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 anchor and t...
