Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Referring to fig. 1, an embodiment of the present application provides a multi-platform synchronous live broadcasting method, including:
s1, receiving a live broadcast starting instruction, wherein the live broadcast starting instruction carries N live broadcast platform marks, N is not less than 1, and a single live broadcast platform mark corresponds to a single live broadcast platform;
s2, acquiring audio and video data of the anchor user type;

and S4, transmitting the audio and video data cached in the data buffer area to each live broadcast platform according to the IP address of each live broadcast platform through a system public gateway, so that each live broadcast platform can play the audio and video data.
In this embodiment, the main execution body of the live broadcast method is an intelligent terminal, the intelligent terminal is preferably a handheld electronic device such as a tablet computer and a mobile phone, and can acquire audio data and video data, and is connected to the server through a wireless network, where the form of the intelligent terminal is not specifically limited. A system public gateway, a data buffer area and a live broadcast management module (a specific form can be a live broadcast management APP, so that a user can directly perform corresponding operation on each live broadcast platform through the live broadcast management APP on the intelligent terminal) are established in the intelligent terminal. All external HTTP accesses of the intelligent terminal need to be stored and forwarded through a system public gateway, the system public gateway records the IP addresses of live broadcast platforms corresponding to live broadcast APPs installed at the current intelligent terminal, and the IP packets received by the intelligent terminal can be analyzed. And if the source IP address in the analyzed IP packet is the IP address of the live broadcast platform, forwarding the IP data stream related to the IP packet to a live broadcast management module by the system public gateway, and pushing the IP data stream to a corresponding live broadcast APP by the live broadcast management module so as to facilitate the user to check. The data buffer area is used for storing data to be transmitted externally by the intelligent terminal and data fed back to the intelligent terminal by each live broadcast platform, so that a processing method which can not respond to multi-platform live broadcast information interaction simultaneously is provided for a user. Live broadcast management module is used for managing each live broadcast APP that installs on the intelligent terminal specially, and the specific form of live broadcast management module can be for live broadcast management APP, and the user can select one key activation intelligent terminal on all live broadcast APPs after logging in live broadcast management APP, also can be through the mode of clicking, selects one or more live broadcast APPs that need the activation, sends the live broadcast promptly and opens the instruction. The live broadcast starting instruction carries N live broadcast platform marks, N is not less than 1, and each live broadcast platform mark corresponds to each live broadcast platform. The method comprises the steps that after receiving a live broadcast starting instruction of a user, the intelligent terminal starts live broadcast, then analog signals of user voice are collected through a microphone and converted into PCM coded original data, and then the PCM coded original data are coded and compressed into data in formats such as MP3 and the like to form audio data; and moreover, images of users are collected through equipment such as a camera and the like to form YUV coded original data, and the YUV coded original data are coded and compressed into video data in H.264 and other formats, so that the acquisition of audio and video data of the type of the anchor user during live broadcasting is realized. The intelligent terminal caches audio and video data in a data buffer area, and then the audio and video data which are live broadcast by a user are concurrently transmitted to live broadcast platforms corresponding to live broadcast APPs according to IP addresses of the live broadcast platforms by using a multi-IP concurrent connection technology of a 4g/5g network through a system public gateway, so that the live broadcast of the live broadcast APPs to a plurality of live broadcast platforms on one intelligent terminal is synchronously realized. In the live broadcast process, a user only needs to be on an intelligent terminal, the operation of a plurality of live broadcast APPs can be completed, the live broadcast operation on different live broadcast platforms is realized, simplicity and convenience are realized, and the experience sense of the user in the live broadcast process is effectively provided.
Further, after the step of receiving a live broadcast start instruction, the method includes:
s5, judging whether the numerical value of N is not less than 2;
and S6, if the numerical value of N is not less than 2, dividing a display interface into N sub-screens according to the number of the live broadcast platform marks, wherein each sub-screen displays a live broadcast platform corresponding to each live broadcast platform mark.
In this embodiment, the user can open all live APP on the intelligent terminal by one key after logging in the live broadcast management APP, and also can select one or more live broadcast APPs that need to be opened currently through the mode of clicking. Specifically, the intelligent terminal can select whether to open the split screen function according to N live broadcast platform marks (live broadcast APP corresponding to the live broadcast platform marks) carried by the live broadcast opening instruction after receiving the live broadcast opening instruction input by the user. If N is not less than 2, the intelligent terminal can select the screen space occupied by the live broadcast screen corresponding to each live broadcast platform according to the number of live broadcast APPs started by the user. The intelligent terminal takes the rest areas of the display interface as a live broadcast interface except for the display of necessary status bars (such as a signal bar and an electric quantity bar of the intelligent terminal). And then, according to the number of the marks of the live platform, splitting the screen of the currently available display interface. For example, if the number of live APP currently started by the user is N, the user divides the available display interface of the terminal, excluding the status bar, into N, and each split screen correspondingly displays a single live platform. The sizes of the split-screen display interfaces can be the same or different. The user can adjust the size of each split-screen display interface according to the self requirement, and the layout position of each split-screen display interface on the main display interface is changed. Preferably, each split screen generated by the intelligent terminal has a display interface with the same size, the split screens with the same size are convenient to arrange, and the integral arrangement has higher attractiveness. The intelligent terminal needs to perform bottom layer development on a system of the intelligent terminal to realize a split screen function when different live broadcast platforms are synchronously live broadcast, and by taking an android system as an example, developers can modify related calling parts and related codes through OpenGLES (open language systems) on a frame layer, so that the intelligent terminal can realize a multi-screen function.
Further, after the step of equally dividing the display interface into N sub-screens according to the number of the live platform marks, the method includes:
and S6, respectively constructing a virtual input device in each split screen.
In this embodiment, after equally dividing the currently available display interface into N split screens according to the number of selected live APP, the intelligent terminal may separately construct a virtual input device, such as a virtual microphone and a virtual camera, for each split screen, and display the icon of the constructed virtual input device in a preset region of the split screen, such as below the split screen display interface, side by side. The virtual input equipment in each split screen only corresponds to one live broadcast platform, the virtual microphone and the virtual camera are used for collecting audio and video data when a user is in live broadcast, and the audio and video data are transmitted to the corresponding live broadcast platform. In the live broadcast process, a user can independently operate the virtual input equipment on the split screen to realize independent management of audio and video data during live broadcast of a single live broadcast platform. For example, the user can close the virtual microphone on the split screen a by means of clicking, and after the virtual microphone of the split screen a is closed, the live broadcast platform corresponding to the split screen a can only receive video data during live broadcast of the user, and cannot acquire audio data. And the live broadcast platforms corresponding to other split screens are not affected, and the audio and video data of the user can be received.
Further, the step of constructing a virtual input device on each of the split screens includes:
s601, loading a virtual sound card;
and S602, calling a pre-programmed driving program to drive the virtual sound card, and realizing the construction of the virtual microphone on the split screen.
In this embodiment, the virtual input device constructed by the intelligent terminal includes a virtual microphone, and is used to collect audio data during live broadcasting of the user. The intelligent terminal needs to make bottom layer development on a system and construct a virtual microphone so that the intelligent terminal can be called in different split screen areas. In this embodiment, an android system is taken as an example for explanation, when a virtual microphone is constructed, an intelligent terminal needs to load a virtual sound card first, and then calls a pre-programmed driver to drive the virtual sound card, so that the construction of the virtual microphone in a split screen manner is completed, and the intelligent terminal can independently collect audio data of a user during live broadcasting through the virtual microphone. The driver is written by developers on the bottom layer of the android system in advance according to the virtual sound card, and after the driver is written into the system of the intelligent terminal, the driver is called conveniently.
Further, the live broadcasting method further includes:
s7, receiving feedback information sent by each live broadcast platform;
and S8, caching the feedback information in the data buffer zone corresponding to each live broadcast platform through the system public gateway.
In this embodiment, in the live broadcasting process of the user, the viewer may interact with the user (for example, a bullet screen message sent by the viewer when watching the live broadcasting), and the interactive information generated by the viewer of the live broadcasting platform may be collected to the platform server corresponding to the live broadcasting platform. The platform server transmits the data stream of the interactive information to the receiving terminal of the anchor according to the IP address of the anchor, the live room information and the like. In this embodiment, the intelligent terminal of the user receives the feedback information transmitted by each live broadcast platform through the system public gateway, and repackages the feedback information at the system public gateway according to the system requirements (such as data format) of the intelligent terminal to obtain feedback data packets corresponding to each feedback information, so as to adapt to the system requirements of the intelligent terminal. The system public gateway distributes each feedback data packet to a corresponding data buffer area for caching by identifying platform characteristic information (such as a platform IP) carried in the feedback data packet, so that the problem that a user cannot react and process in time because a large amount of feedback information is output to an intelligent terminal at the same time is avoided.
Further, after the step of caching the feedback information in the data buffers respectively corresponding to the live broadcast platforms through the system public gateway, the method includes:
and S9, outputting the feedback information according to the receiving time sequence corresponding to the feedback information.
In this embodiment, the feedback information transmitted by each live broadcast platform can be directly read out through the speaker output device of the intelligent terminal, and because the speaker device can only output one piece of feedback information at the same time (in order to avoid confusion of users, the intelligent terminal cannot play multiple pieces of feedback information at the same time), the output sequence of the feedback information needs to be sequenced. Specifically, after caching the feedback information of each live broadcast platform to a data buffer area through a system public gateway, the intelligent terminal respectively identifies the receiving time of each feedback information, and then outputs each feedback information according to the receiving time sequence corresponding to each feedback information. Preferably, the user can set priorities for each live broadcast platform according to the needs of the user (for example, the priority of the live broadcast platform with a large vermicelli amount is higher than the priority of the live broadcast platform with a small vermicelli amount), and the intelligent terminal can also automatically set the priority of each live broadcast platform according to the watching amount (for example, the priority corresponding to the live broadcast platform with a large watching amount is higher), and after receiving the feedback information transmitted by each platform, the intelligent terminal can firstly output the feedback information with the high priority of the live broadcast platform according to the set priority, so that the user is prevented from missing important feedback information.
Further, the step of caching the feedback information in the data buffers respectively corresponding to the live broadcast platforms through the system public gateway includes:
s801, repacking the feedback information according to system requirements at the system public gateway to obtain feedback data packets corresponding to the feedback information respectively;
s802, distributing each feedback data packet to the corresponding data buffer area for caching according to the characteristic information of each live broadcast platform.
In this embodiment, after receiving the feedback information, the intelligent terminal repackages the data stream of each feedback information according to the system requirements by the system common gateway to obtain feedback data packets corresponding to each feedback information, so as to adapt to the system requirements (for example, form requirements such as data format, etc.) of the intelligent terminal. Each live broadcast platform has respective corresponding characteristic information (different live broadcast platforms correspond to different timestamps and special character strings), and the data stream transmitted by the live broadcast platform carries the characteristic information of the platform. And the system public gateway identifies the feedback data packets corresponding to the live broadcast platforms through the characteristic information of the live broadcast platforms, so that the feedback data packets are distributed to the data buffer areas of the corresponding live broadcast platforms for caching, and the subsequent output action is waited.
According to the multi-platform synchronous live broadcast method provided by the embodiment, after receiving a live broadcast starting instruction, an intelligent terminal acquires audio and video data of a main broadcast user type, then caches the audio and video data to a data buffer area, and then transmits the audio and video data cached in the data buffer area to a plurality of live broadcast platforms in parallel according to IP addresses of the live broadcast platforms through a system public gateway, so that the whole flow of multi-platform live broadcast is completed. Because the system public gateway and the data buffer area are arranged in the intelligent terminal, after the audio and video data are cached, the audio and video data are concurrently transmitted to the live broadcast platforms by utilizing a multi-IP concurrent connection technology of a 4g/5g network in the system public gateway, so that synchronous live broadcast on the live broadcast platforms is realized on one intelligent terminal, the complexity of live broadcast operation of a user is effectively reduced, and the operation experience of live broadcast of the user is improved.

For example, if the number of live APP currently started by the user is N, the user divides the available display interface of the terminal, excluding the status bar, into N, and each split screen correspondingly displays a single live platform. The sizes of the split-screen display interfaces can be the same or different. The user can adjust the size of each split-screen display interface according to the self requirement, and the layout position of each split-screen display interface on the main display interface is changed. Preferably, each split screen generated by the intelligent terminal has a display interface with the same size, the split screens with the same size are convenient to arrange, and the integral arrangement has higher attractiveness. The intelligent terminal needs to perform bottom layer development on a system of the intelligent terminal to realize a split screen function when different live broadcast platforms are synchronously live broadcast, and by taking an android system as an example, developers can modify related calling parts and related codes through OpenGLES (open language systems) on a frame layer, so that the intelligent terminal can realize a multi-screen function.
Further, the live broadcast device further includes:
and the building module 7 is used for building the virtual input equipment in each split screen respectively.
In this embodiment, after equally dividing the currently available display interface into N split screens according to the number of selected live APP, the intelligent terminal may separately construct a virtual input device, such as a virtual microphone and a virtual camera, for each split screen, and display the icon of the constructed virtual input device in a preset region of the split screen, such as below the split screen display interface, side by side. The virtual input equipment in each split screen only corresponds to one live broadcast platform, the virtual microphone and the virtual camera are used for collecting audio and video data when a user is in live broadcast, and the audio and video data are transmitted to the corresponding live broadcast platform. In the live broadcast process, a user can independently operate the virtual input equipment on the split screen to realize independent management of audio and video data during live broadcast of a single live broadcast platform. For example, the user can close the virtual microphone on the split screen a by means of clicking, and after the virtual microphone of the split screen a is closed, the live broadcast platform corresponding to the split screen a can only receive video data during live broadcast of the user, and cannot acquire audio data. And the live broadcast platforms corresponding to other split screens are not affected, and the audio and video data of the user can be received.
Further, the virtual input device includes a virtual microphone, and the building module 6 includes:
the loading unit is used for loading the virtual sound card;
and the driving unit is used for calling a pre-programmed driving program to drive the virtual sound card so as to realize the construction of the virtual microphone on the split screen.
In this embodiment, the virtual input device constructed by the intelligent terminal includes a virtual microphone, and is used to collect audio data during live broadcasting of the user. The intelligent terminal needs to make bottom layer development on a system and construct a virtual microphone so that the intelligent terminal can be called in different split screen areas. In this embodiment, an android system is taken as an example for explanation, when a virtual microphone is constructed, an intelligent terminal needs to load a virtual sound card first, and then calls a pre-programmed driver to drive the virtual sound card, so that the construction of the virtual microphone in a split screen manner is completed, and the intelligent terminal can independently collect audio data of a user during live broadcasting through the virtual microphone. The driver is written by developers on the bottom layer of the android system in advance according to the virtual sound card, and after the driver is written into the system of the intelligent terminal, the driver is called conveniently.
Further, the live broadcasting device further includes:
a second receiving module 8, configured to receive feedback information sent by each live broadcast platform;
and the second cache module 9 is configured to cache, through the system public gateway, each piece of feedback information in the data buffer area corresponding to each live broadcast platform.
In this embodiment, in the live broadcasting process of the user, the viewer may interact with the user (for example, a bullet screen message sent by the viewer when watching the live broadcasting), and the interactive information generated by the viewer of the live broadcasting platform may be collected to the platform server corresponding to the live broadcasting platform. The platform server transmits the data stream of the interactive information to the receiving terminal of the anchor according to the IP address of the anchor, the live room information and the like. In this embodiment, the intelligent terminal of the user receives the feedback information transmitted by each live broadcast platform through the system public gateway, and repackages the feedback information at the system public gateway according to the system requirements (such as data format) of the intelligent terminal to obtain feedback data packets corresponding to each feedback information, so as to adapt to the system requirements of the intelligent terminal. The system public gateway distributes each feedback data packet to a corresponding data buffer area for caching by identifying platform characteristic information (such as a platform IP) carried in the feedback data packet, so that the problem that a user cannot react and process in time because a large amount of feedback information is output to an intelligent terminal at the same time is avoided.
Further, the live broadcast device further includes:
and the output module 10 is configured to output each piece of feedback information according to a corresponding receiving time sequence.
In this embodiment, the feedback information transmitted by each live broadcast platform can be directly read out through the speaker output device of the intelligent terminal, and because the speaker device can only output one piece of feedback information at the same time (in order to avoid confusion of users, the intelligent terminal cannot play multiple pieces of feedback information at the same time), the output sequence of the feedback information needs to be sequenced. Specifically, after caching the feedback information of each live broadcast platform to a data buffer area through a system public gateway, the intelligent terminal respectively identifies the receiving time of each feedback information, and then outputs each feedback information according to the receiving time sequence corresponding to each feedback information. Preferably, the user can set priorities for each live broadcast platform according to the needs of the user (for example, the priority of the live broadcast platform with a large vermicelli amount is higher than the priority of the live broadcast platform with a small vermicelli amount), and the intelligent terminal can also automatically set the priority of each live broadcast platform according to the watching amount (for example, the priority corresponding to the live broadcast platform with a large watching amount is higher), and after receiving the feedback information transmitted by each platform, the intelligent terminal can firstly output the feedback information with the high priority of the live broadcast platform according to the set priority, so that the user is prevented from missing important feedback information.
Further, the second cache module 8 includes:
the packaging unit is used for repackaging the feedback information according to the system requirement at the system public gateway to obtain feedback data packets corresponding to the feedback information respectively;
and the distribution unit is used for distributing each feedback data packet to the corresponding data buffer area for caching according to the characteristic information of each live broadcast platform.
In this embodiment, after receiving the feedback information, the intelligent terminal repackages the data stream of each feedback information according to the system requirements by the system common gateway to obtain feedback data packets corresponding to each feedback information, so as to adapt to the system requirements (for example, form requirements such as data format, etc.) of the intelligent terminal. Each live broadcast platform has respective corresponding characteristic information (different live broadcast platforms correspond to different timestamps and special character strings), and the data stream transmitted by the live broadcast platform carries the characteristic information of the platform. And the system public gateway identifies the feedback data packets corresponding to the live broadcast platforms through the characteristic information of the live broadcast platforms, so that the feedback data packets are distributed to the data buffer areas of the corresponding live broadcast platforms for caching, and the subsequent output action is waited.
According to the platform synchronous live broadcast device provided by the embodiment, after the intelligent terminal receives a live broadcast starting instruction, audio and video data of a main broadcast user type are acquired, then the audio and video data are cached in the data buffer area, then the audio and video data cached in the data buffer area are transmitted to the plurality of live broadcast platforms in a concurrent mode according to the IP addresses of the live broadcast platforms through the system public gateway, and the whole process of multi-platform live broadcast is completed. Because the system public gateway and the data buffer area are arranged in the intelligent terminal, after the audio and video data are cached, the audio and video data are concurrently transmitted to the live broadcast platforms by utilizing a multi-IP concurrent connection technology of a 4g/5g network in the system public gateway, so that synchronous live broadcast on the live broadcast platforms is realized on one intelligent terminal, the complexity of live broadcast operation of a user is effectively reduced, and the operation experience of live broadcast of the user is improved.
