As shown in fig. 1, the embodiment of the invention discloses an auxiliary design method for a television live broadcast scheme, which comprises the following steps:
s1, building a preview simulation system containing live broadcast content;
s2, generating a plurality of virtual cameras in the rehearsal simulation system according to parameters set by a user;
s3, calculating to obtain videos shot by each virtual camera in the rehearsal simulation system, and rendering and outputting the videos;

and S6, outputting a television live broadcast scheme comprising the virtual camera parameters and the program guide scheme.
The auxiliary design method of the television live broadcast scheme aims to provide a method and a platform for designing the live broadcast scheme for a television station providing live broadcast service, and the live broadcast scheme is generated in an auxiliary mode according to a preview effect. The live broadcast scheme mainly includes two parts of content: firstly, the arrangement of the cameras and secondly, the editing and outputting of the shooting results of different cameras. In the method provided by the embodiment of the present invention, some commonly used camera layout schemes may be preset in step S2 and provided for the user to select; or setting a personalized camera layout scheme by a user, and generating a plurality of virtual cameras in the rehearsal simulation system according to the scheme set by the user. In step S3, the video captured by each virtual camera is obtained by previewing the simulation system and the camera parameters and rendered for output. In step S4, according to the director scheme set by the user, multiple videos are integrated and edited, and finally a live video, that is, a live video seen by the viewer on the tv, is output. In step S5, the user may make multiple modifications to the camera parameters and the director' S profile until a satisfactory live video is obtained. In the whole method, the user focuses on the specific content and quality of the finally obtained live video, once the user obtains a satisfactory live video, all parameters required to be used in the live video can be output through the step S6 and are executed in the live video according to the reference, so that the design process of the live video is greatly facilitated, and the design difficulty is reduced.
According to a specific implementation manner of the embodiment of the invention, the virtual camera parameters set by the user are divided into three categories: camera performance parameters, camera position parameters and camera control parameters.
In the arrangement scheme of the cameras, performance parameters of the cameras, such as resolution, sensitivity, signal-to-noise ratio and the like of the cameras, are included, so that the result output by live preview is consistent with the live broadcast effect of the actual performance as much as possible, and reference data are provided for selection of the live cameras. The camera layout scheme should also include camera position parameters, that is, where each virtual camera should be laid out in the simulated preview system, which can be expressed by three-dimensional coordinates of the position, so as to provide reference data for the position where the live cameras are laid out in the actual performance scene. The camera layout scheme should also include camera steering parameters, such as adjustment of various angles and focal lengths of the cameras; parameters whose position changes over time should also be included for certain special types, such as a flying cat camera that can move during a performance. The camera steering parameters provide reference data for the adjustment and control of the camera in the actual performance scene.
According to a specific implementation manner of the embodiment of the present invention, the director scheme is a set of director rules, and the director rules include a camera switching trigger condition and a corresponding live signal.
As shown in fig. 2, a plurality of director schemes 1, for example, different styles of director schemes such as liveliness, seriousness, art, etc., may be included in step S4, where the director schemes are a set of director rules 2. The director rule 2 includes a camera switching trigger condition and a corresponding live signal, that is, one output signal corresponding to a certain virtual camera. And when the trigger condition is met, executing corresponding switching operation to switch to the live broadcast signal corresponding to the trigger condition.
The camera switching trigger condition in the director rule may comprise multiple types. In the simplest case, this could be a time-dependent trigger, such as setting up a live signal corresponding to a close-up of an actor when the performance has progressed to a certain point in time. The event may be an absolute time, e.g., eight, twelve; but also relative times, such as the show going to a few minutes, etc.
The camera switching trigger conditions in the director rule are not flexible enough if only the trigger conditions related to time are included, because the time of the actual performance is not necessarily completely consistent with the time in the preview system, so that the live broadcast scheme obtained by the live broadcast preview system cannot be executed in reference during the actual performance. The camera switch trigger condition may also be a key event related trigger condition, such as a time of start of a third program, a presenter flagging action trigger, a director request trigger, etc. In addition to the cases disclosed in the embodiments of the present invention, the camera switching triggering condition may be implemented or applied by different specific implementations according to specific application occasions.
According to a specific implementation manner of the embodiment of the present invention, step S4 includes a director scheme selecting step, and the user previews the live broadcast effect corresponding to each director scheme and selects the used director scheme.

According to a specific implementation manner of the embodiment of the present invention, after step S3, the method further includes a step of making and outputting a special effect, where the special effect processing is performed on the output signal of the virtual camera video rendering to generate a special effect video; correspondingly, the corresponding live signal in the director rule comprises a special effect video signal.
In live broadcasting, some special effect shots, such as slow motion, sometimes need to be added. Because the video rendering output of the virtual camera is a direct shooting signal, a special step needs to be added in the method for special effect processing. The input signal of the special effect processing step is a plurality of virtual camera video rendering output signals, and the output signal is a signal subjected to special effect processing. The special effect processing signal is also used as a path of live broadcast signal which can be switched by the director module, as well as the video rendering output signals of other virtual cameras.
According to a specific implementation manner of the embodiment of the present invention, in step S4, a manual switching interface is provided, through which the user manually sets the switching of the live broadcast signal, browses the effect of the manual switching, and adds the set switching as a director rule to the corresponding director scheme.
Step S4 includes a function of switching according to the director scheme set and selected by the user. Meanwhile, step S4 also provides a manual switching interface for facilitating user interaction, through which the user can manually set the switching of the live broadcast signal at any time, browse the effect of the manual switching, if the effect is not good, the manual switching can be abandoned, and if the effect is satisfactory, the set switching can be added to the corresponding program director scheme as a program director rule.
According to a specific implementation manner of the embodiment of the present invention, the director rule is obtained by learning an existing video, and the specific method is as follows:
carrying out shot segmentation on the existing live video;
marking the triggering condition of the segmentation point;
and identifying live broadcast signals corresponding to the live broadcast videos before and after the division point.
The embodiment of the invention also discloses an intelligent learning method of the director rule. The existing live video is used as a learning resource, and shot segmentation points are identified through a shot segmentation technology, so that a new director rule is learned.
