Technical Field
The invention relates to the field of live video, in particular to an automatic live scene video making system.
Background
The video live broadcast service is evolved on the basis of the on-demand service. In the video on demand service, all programs are stored in a server in the form of streaming media files. The program source in the video live broadcast service is generally a television signal.
The television signal is first decomposed into image signals and sound signals by the television box, and if the program source itself is image signals and sound signals, signals output from devices such as a video recorder do not need to be decomposed. In the case of analog signals, they must be converted to digital signals by a digital-to-analog converter. The digital signal is then stored in a server by generating a live file through a streaming media encoder (which may be a hardware encoder or a software encoder).
The video live broadcast refers to live broadcast by utilizing the internet and a streaming media technology, and the video is combined with rich elements such as images, characters and sounds, has a luxuriant sound and a good effect, and gradually becomes a mainstream expression mode of the internet. The video creates strong scene sense through real and vivid propagation, attracts the eyeball, and achieves the propagation effect of impressive and lasting memory.

Detailed Description
An embodiment of the live scene video automatic production system of the present invention will be described in detail below with reference to the accompanying drawings.
The simple understanding that the broadcast is in the speech of others; the host is speaking himself. The host does much more work than the announcer, and is a complex of the announcer and the host. For example, a general broadcaster just needs to broadcast and read according to manuscripts, and a host usually needs to do a series of tasks such as planning, editing, interviewing, making, directing, and hosting.
The reader-type presenter is closer to the definition of the anchor. Most news programs such as "the sky of the dynasty," the news of the whole day, "and" the news linkage, "are" broadcast and read "by using a word extractor as a basic working means. The announcer only broadcasts according to the manuscript objectively, and few individuals play on the spot.
Besides, the presiding of the reading-type program or the "anchor broadcasting" of some civil-type programs for speaking news also needs to use the profound occupation literacy of news and knowledge accumulation, agile thinking, language organization and expression ability to "speak news" and "speak news" for audiences to have own view and attitude. The anchor is the integration of the host and the broadcaster, and the technical background of the broadcast can be achieved.
At present, in the actual management of live broadcast video operators, the anchor is required to record videos and upload the videos in a delayed and short time, so that the time can be acquired for content verification, the reward of the anchor mainly depends on the video production time and the video interaction heat, however, the former easily makes the anchor record meaningless videos, for example, long-time videos which lack interaction, even videos of which the anchor is not on site, and considerable economic loss is caused to the live broadcast video operators.

the nonlinear filtering equipment is connected with the enhancement execution equipment and is used for executing nonlinear filtering processing on the received enhancement execution image so as to obtain and output a corresponding nonlinear filtering image;
the variable quantity analysis equipment is connected with the nonlinear filtering equipment and is used for receiving a plurality of nonlinear filtering images respectively corresponding to a plurality of frames of instant captured images and sending a recording ending instruction when the variable quantity of the image content among the plurality of nonlinear filtering images is lower than a preset bit threshold value;
the variation analysis device is further configured to issue a record keeping instruction when the variation of the image content among the plurality of nonlinear filtered images is higher than or equal to the preset bit threshold;
