Detailed Description
The present invention is described in terms of particular embodiments, other advantages and features of the invention will become apparent to those skilled in the art from the following disclosure, and it is to be understood that the described embodiments are merely exemplary of the invention and that it is not intended to limit the invention to the particular embodiments disclosed. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
As shown in fig. 1, the present embodiment provides a slow live broadcasting system capable of automatically switching pictures, where the system includes a plurality of network cameras, a cloud director and a slow live broadcasting room.
The plurality of network cameras are used for acquiring a plurality of paths of video signals and transmitting the video signals to the cloud director.
And the cloud broadcasting guide platform is used for carrying out timing automatic switching control on each path of video signal and outputting a video stream to the slow live broadcasting room for live broadcasting.
Specifically, in this embodiment, the cloud director includes a channel setting module, where the channel setting module is configured to set a channel for each network camera, and the network cameras perform stream pushing according to a preset stream pushing address corresponding to the channel.
A multi-path cloud broadcasting guide platform is started at a broadcasting cloud background. After the cloud broadcasting guide platform is started, clicking a setting button of each channel on a channel setting interface to obtain a stream pushing address of each channel, pushing the channel of one broadcasting guide platform by each camera, respectively filling the stream pushing addresses in the network camera platform, and starting stream pushing.
The cloud director comprises a timing task setting module, and the timing task setting module is used for setting the switching time of each channel video signal. By setting a timing task in the cloud director, it is possible to set a screen for switching a specified channel at a specified point in time. After the setting is finished, the video pictures are output to the slow live broadcast, and the user can see the video pictures.
The cloud director platform is also used for transcoding the video stream into a video stream format of a broadcasting and television cloud platform standard so as to play the video stream in a slow live broadcasting room. The transcoding is carried out in the video output process, so that the normal playing of the video can be guaranteed.
Furthermore, the cloud broadcasting platform can also be used for closing video audios, adding one path of background music, synthesizing audio and video, and outputting the audio and video to a slow live broadcasting room for playing, so that the atmosphere sense is increased.
And the slow live broadcast room is used for automatically switching the played video pictures according to the set time point.
Furthermore, the system also comprises a third-party video playing platform, wherein the third-party video playing platform is used for acquiring the synchronous video signal pushed in the slow live broadcasting room and carrying out live broadcasting. If the user has an official buffeting account number or a quick account number and the like, a third-party plug-flow address can be filled in a slow live broadcast room, namely, the third-party plug-flow can be carried out to a third-party platform by one key, and the simultaneous live broadcast of multiple platforms is realized.
Further, the slow live broadcast room in this embodiment implements different live broadcast related functions through a plurality of micro applications.
The slow live broadcast system in the implementation is dedicated to providing a whole set of 24-hour uninterrupted slow live broadcast solution for clients, and comprises a plurality of third-party platforms such as video acquisition, video stream making, one-key distribution, jitter starting and the like. The live broadcast room provides a 50+ interaction function, and fast commercial change is realized by combining a platform with an own mall, for example, slow live broadcast in a mall can be conducted to offline mall; the scenic spots are broadcast in a live mode slowly, and tickets can be sold in combination with online shopping malls; the direct broadcasting in driving schools can be realized by combining an entry questionnaire or a shopping mall, and online entry and the like can be realized.
The concept of "micro-applications" arises from the "micro front end", which is a branched variant belonging to the "micro front end"; the micro application technology can enable two originally irrelevant SPA applications to be integrated into a parent-child whole through a bridge framework. The micro application packages and outputs the sub application under the condition that CSS is not extracted into a UMD format, a main application end initiates a request to add a sub application JS file, and a Proxy/Snapshoot-based JS sandbox is used for realizing main and sub data isolation during operation, so that the main and sub applications are loaded mutually and do not influence each other; and simultaneously, the mode of a combination selector and a micro application unique identifier is used for realizing the mode isolation of the main and sub applications, so that the sub applications are loaded and run in the main application.
In order to avoid the problems of iteration difficulty and mode copying difficulty caused by a single large module, in the technical scheme of broadcasting and television slow live broadcasting, the embodiment adopts the concept of micro application to quickly expand and introduce the existing functions and common function modules of the platform. Through the mode, the existing various live broadcast related function modules in the platform can be quickly introduced, the cost of iterative maintenance is reduced while the product form is unified, and the scheme based on the micro application can realize the online hot updating capability of the sub application independence.
The broadcasting and television cloud slow live broadcast in the implementation is combined with a local mall, so that a user can not only watch the slow live broadcast but also know local culture and local special products through the characteristic scenic spots of the local live broadcast, and the user stickiness is increased by combining 50 interactive functions such as lottery red packet and the like on the platform, so that the audience can come to a live broadcast room to buy when thinking about the local special products, and a positive money sucking effect is formed.
