Description
Technical Field
The application relates to the field of live video broadcasting guide broadcasting, in particular to a method and a system for switching program scenes to a preset monitoring window.
Background
In the live video broadcasting guide broadcasting platform, live broadcasting, guide broadcasting and push stream software are core components. Existing multicast station software is broadly divided into two types: a hardware director and a cloud director (in the form of a Web-side). The platform is a cloud broadcasting guide table of a client, and the client comprises a Web end.
In general, the basic modules in the cloud director console mainly cover the following parts: the system comprises several modules including guide table list management, input signal sources, mixed stream layout, caption materials, transition switching, PVW (program, main monitor) main monitor, sound console, signal output (conference output and live broadcast output), program list and image matting. The application focuses on the program list, transition switching, PVW pre-monitoring and PGM main monitoring module in the cloud broadcasting guide station.
PVW the pre-monitor window is used for previewing the input signal source added by the user and the mixed stream layout signal source picture in real time, and the PGM main monitor is used for previewing the signal picture output by live broadcast in real time. And through a transition switching function, the signal exchange of the PVW pre-monitoring picture and the PGM main monitoring picture is realized.
In the existing director, the program list functional module generally arranges various input signal sources (such as pictures, video on demand, live streaming, real-time conference signal sources and the like) and mixed stream layout signal sources according to a specified sequence, and meanwhile, performs switching setting for each signal source, including setting a transition special effect type and a transition time length for switching the signal source to the PGM main monitor, and setting a duration for switching the signal source to the PGM main monitor. For example, if the source is video-on-demand, the start play position of the source may also be set. After the program list is successfully created, the user can select two switching modes, namely manual switching mode or automatic switching mode. In the manual switching mode, a user actively selects one signal source in a program list and switches the signal source to a PGM main monitor window; in the automatic switching mode, a user can select a certain signal source or switch from a first signal source by default, and after the program list starts to play, the program list can be automatically played according to the signal source sequence and the signal source switching configuration when the program list is created, and the cyclic playing of the program list can also be set.
The mixed flow layout is generally formed by mixing and superposing 1-N layers of pictures, and the layers can be any input signal source or other mixed flow layout signal sources. Both a single input signal source and a mixed stream layout signal source may be added to the program listings as scenes. And switching scenes in the program list, namely switching the input signal sources or the mixed stream layout signal sources into the PGM main monitor window according to the appointed sequence, so as to realize the rapid switching of live scenes.
Disclosure of Invention
In the current cloud broadcasting guide table, when the number of active links is many, for example, the number of scene layouts is tens, a few tens of small picture lists appear correspondingly in a signal source list display area. The program list configures the switching sequence of each signal source of the scene layout. When the next scene to be switched needs to be previewed in the PVW pre-monitor window, searching in a small picture list of a signal source list display area is needed, and when the number of small pictures in the small picture list is particularly large, the searching is time-consuming and labor-consuming, is quite inconvenient and is easy to make mistakes. According to the application, the PVW pre-monitor window and the entrance of the PGM main monitor window are directly arranged on the operation function area of each program scene of the program list, so that the search in a small picture list corresponding to the scene layout can be avoided, and the program scene to be previewed can be directly and rapidly cut into the PVW pre-monitor window and/or the PGM main monitor window for previewing.
According to a first aspect of the present application, there is provided a method for switching a program scene to a preset monitoring window, applied to a cloud director client, comprising:
responding to the selected operation of a preset monitoring window option corresponding to a program scene in a program list, and forming a command for switching the program scene to the preset monitoring window;

and pulling the data stream of the program scene from the RTC conference platform and displaying the data stream on the preset monitoring window.
According to a second aspect of the present application, there is provided a method for switching a program scene to a preset monitoring window, applied to a cloud broadcasting platform, comprising:
receiving a command from a cloud director client to switch a program scene to a preset monitoring window;
transmitting a signal source corresponding to the program scene to a preview output assembly of the preset monitoring window to form a data stream of the program scene; and
and pushing the data stream of the program scene to the RTC conference platform.

According to a fifth aspect of the present application there is provided a non-transitory computer storage medium storing a computer program which, when executed by a plurality of processors, causes the processors to perform the methods of the first and second aspects.
According to the method and the system for switching the program scenes to the preset monitoring window, the cloud broadcasting guide client sets the corresponding preset monitoring window options in each program scene of the program list, and when the preset monitoring window options are selected, a command for switching the program scenes to the preset monitoring window is formed, so that the cloud broadcasting guide platform transmits a signal source corresponding to the program scenes to a preview output component of the preset monitoring window, a data stream is formed and is output to an RTC (Real-time Communications, real-time communication) conference platform, and the cloud broadcasting guide client pulls the data stream from the RTC conference platform and displays the data stream in the preset monitoring window. According to the scheme of the application, as the sequence of program scenes in the program list is set, when the next scene to be switched needs to be previewed in the PVW pre-monitor window, the program scenes do not need to be searched in the small picture list of the signal source list display area, but the corresponding program scenes can be searched and switched by setting the corresponding pre-set monitor window options for each program scene, and when the program scenes need to be switched to the PGM main monitor window, the corresponding program scenes can also be searched and switched by setting the corresponding pre-set monitor window options for each program scene. Therefore, when the program scenes are required to be switched, the program scenes are directly switched through the preset monitoring window options set for the program scenes of the program list without searching in the small picture list of the Mimex, so that the efficiency and the accuracy of the program scene switching are improved, and the user experience is improved.

Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Fig. 1 is a schematic diagram of a system for switching subtitle contents according to an embodiment of the present application. As shown in fig. 1, the system includes a cloud director client, an RTC conference platform and a cloud director platform, where the RTC conference platform may include a 100 RTC conference platform, where the RTC conference platform includes RTC-sdk (divided into web/windows/mac/ios/android versions), a signaling server (RTC-signal-server), a media server (RTC-media-server) and a conference control service (RTC-back-end-server); the cloud director platform may be a 100 mix cloud director platform, which includes a signaling server (switch-signal-server) and an underlying server (switch-engine-server). In the system shown in fig. 1, the client establishes long connections with the RTC conference platform, signaling servers of the client and the cloud director platform, and the cloud director platform establishes long connections with the RTC conference platform, respectively, where the long connections may include WebSocket connections.
All signal source video pictures in the cloud director station must be previewed by pulling from the RTC conference platform. When the cloud director platform is started, a long connection, which can be a web socket long connection, is established with the RTC conference platform. After the long connection is established successfully, the RTC preview room is added, the video and audio stream information existing in the room is queried, and each video stream/audio stream is identified by a stream identification ProducerId and a corresponding preview output component. Meanwhile, whether the room is filled with a new push message of the video and audio stream and a stop push message of the released video and audio stream is monitored. And pulling the preview in real time and stopping pulling the preview according to the monitored message. The cloud broadcasting platform is mainly responsible for the pull-stream decoding of input signal sources, the mixed-stream superposition of layout mixed-stream signal sources, the superposition of caption materials, the audio and video processing of transition special effects, filters and the like, and then the processed signal codes are pushed to the RTC conference platform.
As shown in fig. 1, according to some embodiments, the cloud director platform is a componentized platform for online audio and video production, and mainly processes signal input, mixed flow, subtitle superposition, transition and composite picture output of the cloud director platform. The RTC conference platform is a real-time audio and video communication platform, and after the cloud broadcasting platform processes the audio and video signals, the synthesized picture is pushed to the RTC conference platform, and the cloud broadcasting platform client subscribes RTC streams from the RTC conference platform, so that real-time preview of the synthesized picture is realized. The cloud director platform is a componentized system, and each input source (input), layout (me) or output (output) is a separate component, and components are connected through nodes, for example, a connection between a component a and a component B is established and may be represented as a connectinode (componentA, componentB), and a connection between a component a and a component B is released and may be represented as a disconnectonode (componentA, componentB), so as to form different pipelines. The input component is the head node of the pipeline and the output component is the tail node of the pipeline. Within a single multicast station, each component has a unique ID created by the multicast station signaling server.
The input signal source, the mixed stream layout signal source and the subtitle material added by the cloud broadcasting guide client are independent component components corresponding to the bottom server side, and the pre-monitor PVW and the main monitor PGM. The components can be connected with each other to form a pipeline.
For example, the client adds an input signal source of the video-on-demand file, and the client adds an input signal source preview window in the input signal source list display area. This input source window creates video tags and audio tags for previewing the input source pictures and listening to sound. At the same time, the client sends an instruction switcherAddInput (inputId) to create an input signal source, create preview output component switcherAddOutput (outputId), and component connect instruction switchconnect node (inputId, outputId) to the cloud director platform.
For another example, the client creates a mixed-stream layout signal source, adds a mixed-stream layout preview window in the mixed-stream layout signal source list display area, and creates video tags and audio tags for previewing mixed-stream layout signal source images and listening. Meanwhile, the client sends an instruction switcherAddME (meId) for creating an input signal source to the cloud streaming platform, creates a preview output component switchaddoutput (outputid_me), and sets template information switcherSetMETemplate (templateInfo) of the mixed-stream layout signal source by a component connection instruction switchconnectingnode (meId, outputid_me).
Client creation PVW pre-monitors, in addition to creating preview windows, video tags and audio tags at PVW, sends a create PVW component switcherAddPVW (pvwId), create preview output component switcheraddoutput_ pvw, and component connect instruction switcherconnect_node (pvwId, outputid_ pvw) to the cloud director platform.
Similarly, the client creates PGM master, in addition to creating preview windows, video tags and audio tags in PGM presentation area, sends a create PGM component switcherAddPGM (pgmId), create preview output component switchaddoutput (outputid_pgm), and component connection instruction switchconnect node (pgmId, outputid_pgm) to the cloud director platform.
The cloud broadcasting platform receives an input signal source creation instruction and performs streaming and decoding of audio and video; when receiving an instruction for creating an output assembly, encoding audio and video and pushing; and after receiving the component connection instruction, transmitting audio and video data among the components according to the connection relation. For example, the input component and the output component are connected, so that audio and video data of the input component can be transferred to the output component.
Creating a program list at the client of the cloud broadcasting guide station. According to some embodiments, as shown in fig. 2 and 3, the program list creation process is to arrange the added input signal sources and mixed-flow layout signal sources in a certain order, set a switching mode and a switching special effect of each signal source, and switch to a duration after PGM main supervision. When creating, editing and deleting a program list and switching a certain program scene, the client side sends corresponding information or command to the cloud guide platform. According to some embodiments, a program list send switcherAddPlayList message is created, a program list send switcherModifyPlayList message is edited, a program list send switcherdeletecompount message is deleted, and a program scene send switcherCutPlayScene message is switched.
Fig. 4 is a schematic diagram illustrating an operation of switching a program scene to a preset monitoring window according to an embodiment of the present application. As shown in fig. 4, the cloud director client may create one or more program listings, where each program listing includes a plurality of program scenes, and each program scene has an entry button for switching to a PVW pre-monitor window and/or a PGM main monitor window, that is, a corresponding preset monitor window option is set for each program scene, and this option may be a PVW pre-monitor window option or a PGM main monitor window option. According to some embodiments, either or both of PVW pre-monitor window options and PGM main monitor window options may be set for each program scenario.
According to some embodiments, the client defines a left click event addeventlist (playList, playlistvandler) for the switch to PVW button (corresponding to PVW pre-monitor window option) in the program list, and when the user clicks the switch PVW button on a certain program scene in the program list, the client knows which program scene in which program list needs to be switched to PVW pre-monitor window through the playlistvandler. Clicking the switch to PVW button, the front end of the client receives the button click event, and the client forms a command for switching the program scene to PVW the pre-monitor window according to the selection operation of the PVW pre-monitor window option corresponding to the program scene in the program list. In the event processing method, the client first sends a command to the cloud director platform to switch the program scene to the PVW pre-monitor window, for example, sends a switcherCutToPVW (inputId-a) to inform the cloud director platform. The cloud director platform will first detect PVW whether the component has a front node at present, and will first disconnect the front node from PVW component if any. The component with the source component ID of inputId-A is then connected to the PVW component. At this point, the audio/video data of the input/mixed stream layout source with component ID of inputId-a is passed to the PVW component. PVW component then passes the new audiovisual data to the corresponding Output preview Output component outputId pvw. The Output preview Output component outputid_ pvw encodes the signal in real time and pushes it to the RTC conference platform. The PVW window of the client will pull previews in real time from the RTC conference platform. In this way, PVW pre-monitor window can display the picture of switching to PVW program scene in real time.
According to some embodiments, after receiving a left click event (corresponding to selecting PVW a pre-monitor window option) of which program on the program list needs to be switched to PVW, the client also displays a list of subtitle materials added by the input/mixed stream layout signal source corresponding to the program scene in the subtitle material display area. The client side renders corresponding subtitle material configuration in the subtitle material area by inquiring subtitle material configuration information in the input/mixed stream layout signal source in the local cache. The caption material list comprises the number of caption materials added by the signal source and the starting condition of each caption material.
According to some embodiments, the client defines a left click event addeventlist (playList) for a switch PGM button (corresponding to PGM home watch window option) in a program list, and when the user clicks the switch PGM button on a certain program scene in the program list, the client knows which program scene in which program list needs to be switched to PGM through the playList handle. Clicking a switch to PGM button, the front end of the client receives the button click event, and the client forms a command for switching the program scene to the PGM main monitor window according to the selected operation of the PGM main monitor window options corresponding to the program scene in the program list. And then the client sends a command for switching to the PGM main monitor window to the cloud guide platform, and sends a switchCutPlayScene (inputId-A) to inform the cloud guide platform, and the cloud guide platform can detect whether a program scene to be switched has a transition special effect or not, and if so, the cloud guide platform can set the transition special effect switchSetEffect for the PGM component. And the cloud broadcasting guide platform also judges whether the PGM component has a front node or not, if so, the front node is disconnected from the PGM component, and then the component with the component ID of inputId-A is connected with the PGM component. At this time, the audio/video data of the input/mixed stream layout signal source with the component ID of inputId-a is transferred to the PGM component. The PGM component then passes the new audiovisual data to the subsequent Output preview Output component outputid_pgm. The Output preview Output component outputId_pgm encodes the signal in real time and pushes the signal to the RTC conference platform. The PGM window of the client will pull a preview in real time from the RTC conference platform. In this way, the PGM pre-monitor window can display a screen for switching to PGM program scenes in real time.
According to some embodiments, after a user of the cloud director client performs a selection operation on a PVW pre-monitor window option or a PGM main monitor window option corresponding to a program scene in a program, for example, a left click on a PVW button or a PGM button, the cloud director client first obtains, according to the operation, which program scene of which program scene is subjected to the operation, and obtains the number of the program scene. And in the process of sending a command for switching to a preset monitoring window to the cloud broadcasting guide platform, the serial number of the program scene is sent to the cloud broadcasting guide platform. In the process of establishing the program list, the cloud guide platform client sends corresponding information or commands to the cloud guide platform, namely the cloud guide platform stores the numbers of the program scenes corresponding to the program lists of the client and the signal source component information corresponding to the numbers of the program scenes. For example, for program scene number 1, the corresponding signal source component information is the video-on-demand file input signal source, and the ID of the signal source component is known; for another example, for program scenario number 2, its corresponding source component information is a mixed stream layout source, and the ID of the source component is known, and so on. In this way, the corresponding relation between the serial numbers of the program scenes and the signal source component information is established in the cloud guide platform. After receiving the command of switching to the preset monitoring window and the serial numbers of the program scenes, the cloud broadcasting guiding platform can find out the corresponding signal source assembly information through the serial numbers of the program scenes and the stored corresponding relations, and then connects the found signal source assembly with the preset monitoring window assembly (for example, PVW assembly or PGM assembly). At this time, the audio/video data of the searched input/mixed stream layout signal source of the signal source assembly is transferred to the preset monitoring window assembly. The preset monitor window component then passes the new audio and video data to the corresponding Output preview Output component outputid_ pvw. The Output preview Output component outputid_ pvw encodes the signal in real time and pushes it to the RTC conference platform.
According to some embodiments, after a user of the cloud director client performs a selection operation on a PVW pre-monitor window option or a PGM main monitor window option corresponding to a program scene in a program, for example, a left click on a PVW button or a PGM button, the cloud director client first obtains, according to the operation, which program scene of which program scene is subjected to the operation, and obtains the number of the program scene. After the serial numbers of the program scenes are obtained, the cloud broadcasting guide client side can determine the signal source component information corresponding to the program scenes. And in the process of sending a command for switching to a preset monitoring window to the cloud broadcasting guide platform, the signal source component information is sent to the cloud broadcasting guide platform. After receiving the command of switching to the preset monitoring window and the information of the signal source component, the cloud broadcasting guiding platform connects the signal source component with the preset monitoring window component (for example, PVW component or PGM component). At this time, the audio/video data of the input/mixed stream layout signal source of the signal source assembly is transferred to the preset monitor window assembly. The preset monitor window component then passes the new audio and video data to the corresponding Output preview Output component outputid_ pvw. The Output preview Output component outputid_ pvw encodes the signal in real time and pushes it to the RTC conference platform.
According to some embodiments, after a user of the cloud director client performs a selection operation on a PVW pre-monitor window option or a PGM main monitor window option corresponding to a program scene in a program, for example, a left click on a PVW button or a PGM button, the cloud director client first obtains, according to the operation, which program scene of which program scene is subjected to the operation, and obtains the number of the program scene. After the serial numbers of the program scenes are obtained, the cloud broadcasting guide client selects a picture corresponding to the serial numbers of the program scenes from a plurality of signal source pictures in the signal source list display area.
Based on the system shown in fig. 1, according to one aspect of the present application, a method for switching program scenes to a preset monitoring window by a cloud director client is provided. As shown in fig. 5, the method includes the following steps.
Step S501, in response to a selection operation of a preset monitoring window option corresponding to a program scene in a program list, forming a command for switching the program scene to the preset monitoring window;
step S502, the command is sent to a cloud broadcasting guide platform, so that the cloud broadcasting guide platform transmits a signal source corresponding to the program scene to a preview output component of the preset monitoring window, and forms a data stream of the program scene to be output to an RTC conference platform; and
step S503, pull the data stream of the program scene from the RTC conference platform, and display the data stream in the preset monitoring window.
The preset monitoring window comprises a PVW preset monitoring window and a PGM main monitoring window, wherein PVW preset monitoring window options are selected to switch the program scene to the PVW preset monitoring window, and PGM main monitoring window options are selected to switch the program scene to the PGM main monitoring window.
Thus, step S502 specifically includes:
transmitting a command for switching the program scene to the PVW pre-monitoring window to the cloud broadcasting guide platform under the condition that the pre-monitoring window is PVW pre-monitoring window; and/or
And sending a command for switching the program scene to the PGM main monitor window to the cloud broadcasting guide platform under the condition that the preset monitor window is the PGM main monitor window.
According to some embodiments, after a user of the cloud director client performs a selection operation on a PVW pre-monitor window option or a PGM main monitor window option corresponding to a program scene in a program, for example, a left click on a PVW button or a PGM button, the cloud director client first obtains, according to the operation, which program scene of which program scene is subjected to the operation, and obtains the number of the program scene. After the serial numbers of the program scenes are obtained, the cloud broadcasting guide client side can determine the signal source component information corresponding to the program scenes. And in the process of sending a command for switching to a preset monitoring window to the cloud broadcasting guide platform, the signal source component information is sent to the cloud broadcasting guide platform. According to some embodiments, the command includes the signal source component information corresponding to the program scene to be switched. After receiving the command of switching to the preset monitoring window and the information of the signal source component, the cloud broadcasting guiding platform connects the signal source component with the preset monitoring window component (for example, PVW component or PGM component). At this time, the audio/video data of the input/mixed stream layout signal source of the signal source assembly is transferred to the preset monitor window assembly. The preset monitor window component then passes the new audio and video data to the corresponding Output preview Output component (e.g., outputId pvw or outputId pgm). The Output preview Output component encodes the signal in real time and pushes the signal to the RTC conference platform.
Thus, the method shown in FIG. 5 may further comprise:
step S504, determining a program scene to be switched according to the selected operation; and
step S505, determining corresponding signal source component information according to the program scene to be switched.
According to some embodiments, after a user of the cloud director client performs a selection operation on a PVW pre-monitor window option or a PGM main monitor window option corresponding to a program scene in a program, for example, a left click on a PVW button or a PGM button, the cloud director client first obtains, according to the operation, which program scene of which program scene is subjected to the operation, and obtains the number of the program scene. After the serial numbers of the program scenes are obtained, the cloud broadcasting guide client selects a picture corresponding to the serial numbers of the program scenes from a plurality of signal source pictures in the signal source list display area.
Thus, the method shown in FIG. 5 may further comprise:
step S506, the serial numbers of the program scenes are obtained in response to the selection operation of the preset monitoring window options corresponding to the program scenes in the program list; and
step S507, selecting a corresponding signal source picture in a signal source list display area according to the serial number of the program scene.
Based on the system shown in fig. 1, according to one aspect of the present application, a method for switching program scenes to a preset monitoring window by a cloud broadcasting platform is provided. As shown in fig. 6, the method includes the following steps.
Step S601, receiving a command from a cloud director client to switch a program scene to a preset monitoring window;
step S602, transmitting a signal source corresponding to the program scene to a preview output component of the preset monitoring window, so as to form a data stream of the program scene; and
step S603, pushing the data stream of the program scene to the RTC conference platform.
The cloud director client selects PVW a pre-monitor window option to switch the program scene to PVW the pre-monitor window, selects PGM main monitor window option to switch the program scene to PGM main monitor window.
Thus, step S602 specifically includes:
transmitting a signal source corresponding to the program scene to a preview output component of the PVW pre-monitoring window under the condition that the pre-monitoring window is PVW pre-monitoring window; and/or
And transmitting the signal source corresponding to the program scene to a preview output component of the PGM main monitor window under the condition that the preset monitor window is the PGM main monitor window.
According to some embodiments, in the process of sending a command for switching to a preset monitoring window to the cloud broadcasting guide platform, the serial number of the program scene is sent to the cloud broadcasting guide platform. In the process of establishing the program list, the cloud guide platform client sends corresponding information or commands to the cloud guide platform, namely the cloud guide platform stores the numbers of the program scenes corresponding to the program lists of the client and the signal source component information corresponding to the numbers of the program scenes. In this way, the corresponding relation between the serial numbers of the program scenes and the signal source component information is established in the cloud guide platform. After receiving the command of switching to the preset monitoring window and the serial numbers of the program scenes, the cloud broadcasting guiding platform can find out the corresponding signal source assembly information through the serial numbers of the program scenes and the stored corresponding relations, and then connects the found signal source assembly with the preset monitoring window assembly (for example, PVW assembly or PGM assembly). At this time, the audio/video data of the searched input/mixed stream layout signal source of the signal source assembly is transferred to the preset monitoring window assembly. The preset monitor window component then passes the new audio and video data to the corresponding Output preview Output component outputid_ pvw. The Output preview Output component outputid_ pvw encodes the signal in real time and pushes it to the RTC conference platform.
Thus, the method shown in FIG. 6 may further comprise:
step S604, establishing a corresponding relation between a program scene in a program list of the cloud broadcasting guide client and signal source component information; and
step S605, determining signal source component information corresponding to the program scene according to the correspondence and the number.
According to the method and the system for switching the program scenes to the preset monitoring window, the cloud director client sets the corresponding preset monitoring window options in each program scene of the program list, and when the preset monitoring window options are selected, a command for switching the program scenes to the preset monitoring window is formed, so that the cloud director platform transmits a signal source corresponding to the program scenes to a preview output component of the preset monitoring window to form a data stream and output the data stream to the RTC conference platform, and the cloud director client pulls the data stream from the RTC conference platform and displays the data stream in the preset monitoring window. According to the scheme of the application, as the sequence of program scenes in the program list is set, when the next scene to be switched needs to be previewed in the PVW pre-monitor window, the program scenes do not need to be searched in the small picture list of the signal source list display area, but the corresponding program scenes can be searched and switched by setting the corresponding pre-set monitor window options for each program scene, and when the program scenes need to be switched to the PGM main monitor window, the corresponding program scenes can also be searched and switched by setting the corresponding pre-set monitor window options for each program scene. Therefore, when the program scenes are required to be switched, the program scenes are directly switched through the preset monitoring window options set for the program scenes of the program list without searching in the small picture list of the Mimex, so that the efficiency and the accuracy of the program scene switching are improved, and the user experience is improved.
