Fig. 1 is a flowchart of a method provided by an embodiment of the present invention, and as shown in fig. 1, the present invention provides a studio automation method, including:

step 100: analyzing the MOS command pushed by the manuscript system, and storing the analyzed manuscript information into an automation system;

Step 200: connecting all devices in the studio through a device management page in the automation system;

step 300: writing commands to be sent to different devices in the studio into a control template, wherein the control template comprises device control commands of the studio;

Step 400: creating a broadcasting list on a list editing page of the automatic system, selecting a plurality of manuscript information to be added into the broadcasting list, selecting a piece of news on the list editing page to edit, and selecting the control template to generate a control item to obtain a well-edited broadcasting list; each manuscript information corresponds to a piece of news in the broadcasting list;

Step 500: based on a broadcast control algorithm, a broadcast control page in the automation system carries out broadcast control on the written broadcast list, and the automation system sends a device control command in a control item under the broadcast list to studio equipment through a program.

Specifically, the application method of the unicast control in the embodiment includes the following steps:

① The manuscript system pushes MOS commands, and the manuscript information is saved in an automation system through analysis;

② And connecting the studio equipment successfully through the equipment management page. The studio equipment comprises a sound console, a music player, a switching console, a video server, a graphic packaging engine (comprising a virtual and real engine, an online packaging engine, a background large screen engine and the like), a camera robot, a light console, a video matrix and a magnetic disk video recorder. All the equipment connections are realized through a network, and communication can be realized by filling in correct IP addresses and port numbers. Checking whether the equipment is successfully connected or not only by checking an equipment signal lamp, wherein red represents that the equipment is not connected or fails to be connected, and green represents that the equipment is successfully connected;

③ Commands to be sent to different equipment of the studio are written into a control template containing control commands of the equipment of the studio. The control commands comprise a switching console control command, a sound console control command, a video server control command, a camera robot control command, a lamplight control command, a video matrix control command, a music playing control command and a hard disk video recorder control command;

④ The user creates a playbill on a billing page of the automated system and may select ① a plurality of documents to add to the playbill, each document corresponding to a piece of news in the playbill. The user can select a news to edit in the editing page, and can select ③ control templates created in the editing page to be used for generating a control item;

⑤ The well-written play list can be broadcast-controlled on the broadcast control page, and the automation system can send the device control command in the control item under the play list to the studio device through the program.

As shown in fig. 2, the broadcast control algorithm logic in step ⑤ specifically includes:

I. All news data under the current playlist need to be acquired first. The data of each piece of news includes: news headlines, manuscript content, control items associated with the news. The control project consists of on-line packaging control data, auxiliary data and a set of device control commands. The auxiliary data consists of only one set of device control commands. Each news item may contain any number of control items that will be played in order. All news are arranged according to the order of the news in the playlist, and the first control item under the first news is taken as the control item currently played. The switching station control commands are of two types, which are divided into: PGM handover command, PVW handover command. Video server control commands are of two types, divided into: video play command, video load command;

II. Selecting a video server to receive the command, and polling a video server from the configured list of video servers. Polling selection refers to sequentially cycling through a set of sequences to select an element. For example, if elements of a sequence are ordered A, B, C, then the result of 6 consecutive polls is A, B, C, A, B, C;

And III, assembling the device control command contained in the current control project into a command corresponding to the device control protocol. The device control commands in the control project or auxiliary data are in a format used internally in the automation system and need to be converted into a format recognizable by the studio device. The specific format that the device can recognize is defined by the device vendor, e.g., the video server may use the AMCP or VDCP protocol, which protocol to use in particular is selected by the user in the setup page of the automation system;

And IV, sending the control command which can be identified by the equipment converted in the third step to the corresponding equipment by using the corresponding communication protocol. The communication protocol is typically a computer network communication protocol such as TCP or UDP. The automatic system encapsulates the video matrix control command, the lamplight control command, the camera robot control command, the music playing control command, the video server control command, the switching table control command, the sound console control command and the hard disk video recorder control command into a message of a corresponding communication protocol, and sends the message to corresponding equipment;

And V, if the currently played control item contains one or more auxiliary data, sending a control command contained in each auxiliary data item to the corresponding equipment. The flow of the control command transmission in the auxiliary data is consistent with the step III and the step IV;

VI, if the currently played control item contains online packaging control data, assembling the online packaging control data into an online packaging control command and sending the online packaging control command to online packaging equipment;

and VII, acquiring a next control item to be played. And taking the next control item of the current news as a control item to be played, and taking the first control item of the next news in the playlist as the control item to be played if the current control item is the last item of the news.

And VIII, if the control item to be played contains a switching station control command, assembling the switching station control command into PVW switching commands of the switching station, and sending the PVW switching commands to switching station equipment.

IX, taking the next video server of the current receiving command fetched in the step II as the next video server ready to play

If the control item to be played contains a video control command, the video server control command is assembled into a video loading command and sent to the next video server to be played in step IX

XI, if the control item currently played starts to automatically end, setting a delay task, and automatically taking down the control item to execute the step II and all the steps after the delay of the designated time

And step XII, if the user triggers playing on the playlist control interface of the automatic system, immediately executing the step II.

In the embodiment provided in fig. 3, as shown in fig. 3, the third-party document system 1 is a document system of a different manufacturer, and the automated document access module 2 is implemented by using an independent gateway, and the gateway supports two modes including a MOS protocol and FTP reading. The automation manuscript presentation module 3 typically accesses the display by using a host installed to deploy the automation system main service, and may also access the automation system main service by using other servers for display. The gateway in the automatic manuscript updating and pushing module 4 monitors the change of the manuscript end at fixed time intervals, and once the change occurs, the gateway captures information in real time and pushes the changed manuscript information data to the automatic main service to realize real-time updating of the manuscript content. The automation manuscript holding module 5 will hold the edited playlist content to the database of the data server 6.

Specifically, according to the integration scheme of the data of the different manuscript systems of the multiple factories, the different manuscript systems of the multiple factories can be accessed into the automatic studio, and the compatibility of different studios is achieved. In order to realize the data access of the manuscript systems of different manufacturers, the implementation is realized by developing an independent gateway, and the gateway supports two modes including MOS protocol and FTP reading. The gateway monitors the change of the manuscript end at fixed time intervals, and once the change occurs, the gateway captures information in real time and stores the changed manuscript information data into a database of the data server. The MOS protocol is a standard protocol for the broadcast and television industry for enabling system integration and collaboration in multimedia production and playout processes. The MOS protocol defines a set of specifications and message formats for data exchange and communication between different broadcast and production systems. And the FTP reading is realized by reading XML files in the FTP specific folder and analyzing fields in the files.
