As shown in fig. 1, the system for universal broadcasting voice intercom according to an embodiment of the present invention is composed of five parts, namely a PC browser, an MRC (Media Reactor Center ), an MRS (Media Reactor Switch, media reactor exchange service), OWT (OpenWeb Text), and a terminal. The MRC control terminal is used for realizing voice communication with any one or more terminals in the live broadcast service, and can also realize voice communication between the terminals.
The information interaction between the five parts includes two types, one is a data stream, corresponding to device information, status information, live room information, etc., and the other is a media stream, corresponding to audio-video media information. The data stream is centered on the MRC and interacts with several other parts, respectively. The media stream is generated by the terminal or the PC browser and then is pushed to the terminal or the PC browser through the processing of MRS and OWT, respectively.
The PC browser end is used by a background operator and can access an MRC page of the cloud through the PC browser. MRC, MRS, OWT set up in the high in the clouds server, the terminal is carried by the personnel of external service and uses.
Specifically, the PC browser is used for enabling a user to access the MRC page through the PC browser to send out a voice call demand;
MRC, is used for controlling OWT to create the voice call room; establishing information flow links between each terminal and a voice call room in the system;
MRS, used for obtaining the voice call information pushed by the terminal and forwarding to OWT; pushing the voice mixed stream information generated by OWT to each terminal;
OWT for creating a voice call room; and processing the voice call information to obtain voice mixed flow information.
The following describes the method for speaking the universal live voice in detail by combining the architecture of the universal live voice speaking system.
As shown in fig. 2, the live voice intercom method according to an embodiment of the present invention includes:
step S101, receiving a voice call request sent by a user.
The voice call demand is typically initiated by the user accessing the MRC page through the PC browser, while the terminal will display the status of the call being made. This indicates that the terminal has successfully established a connection with the MRC server and is waiting to receive and transmit voice call data. The terminal prompts that the user can know the current call state in the call so that the user can better manage the voice call.
Step S102, creating a voice call room;
after receiving the voice call request, the MRC creates a voice call room (chat room) according to the request content. The terminal participating in the call will join the voice call room.
Step S103, establishing information flow links between each terminal and the voice call room in the system.
For a terminal to join a call, the MRC needs to establish an information flow link for the terminal voice call room. The specific implementation mode is that MRC applies for two paths of RTMP stream addresses for the created voice call room, one path is used for transmitting the voice call information pushed by the MRS transmission terminal, and the other path is used for transmitting the voice mixed stream information. Two stream addresses are then set to the terminal, and the two RTMP stream addresses are set to the terminal device.
Among them, RTMP is a real-time messaging protocol, a transmission protocol for audio, video and data streams. In the RTMP protocol, data transmission is performed through the TCP protocol.
It should be noted that as other embodiments of the present invention, other various protocol accesses are also supported, including WebRTC, RTSP, HLS, MPEG-DASH, etc.
After the information flow link is established, the voice call can be started.
Step S104, obtaining voice call information pushed by the terminal.
After the voice call information is collected by the terminal, the media stream is transmitted to the cloud server through the stream address, and then the OWT is used for processing.
Step S105, the voice call information is processed to obtain voice mixed flow information.
For the processing process of the voice call information, aiming at the terminals entering a voice call room, acquiring the voice call information pushed by each terminal;
and mixing streams of other terminals except the target terminal to obtain voice mixed stream information aiming at the target terminal.
It is mainly noted that, when the mixed stream is performed, the content of the mixed stream is different for the voice mixed stream information to be pushed by different terminals in the room, and the voice mixed stream information pushed to each target terminal is obtained by mixing voice call information of other terminals except the target terminal.
For example, there are four terminals A, B, C, D in the room, and the voice mixed stream information pushed to the a terminal is obtained by mixing voice call information of the three terminals B, C, D.
The specific execution process is carried out by OWT, and all voice call information is firstly converted into an OWT format; then carrying out mixed flow on the data in the OWT format; and finally, converting the OWT format data after mixed streaming into voice mixed streaming information.
The way of OWT processing voice call information is that firstly voice information is converted into text by using voice recognition technology, the converted text information is represented by using OWT format, then the converted text information is mixed, and finally mixed stream OWT format data is converted into voice mixed stream information. The OWT format is an open standard for describing and sharing text. It is based on Web technology such as HTML, CSS and JavaScript and uses JSON-LD format for data exchange.
The advantage of using the OWT format to process voice call information is that voice is converted into text, and then the text is represented using the OWT format, and sharing of voice information can be achieved by sharing the OWT format information without directly transmitting audio files. Furthermore, OWT is based on the WebRTC protocol, and a real-time communication technology is adopted, so that lower time delay is realized, and the real-time performance is better. And the data stream transmission is adopted, so that the method can adapt to bandwidth change more efficiently, supports point-to-point direct communication, and can realize firewall penetration more easily.
In an embodiment of the present application, the audio format of the supported voice call information includes: AAC, AC3, OPUS, G722, iSAC, iLBC, PCMU, PCMA, nellymoser, etc.
Step S106, pushing the voice mixed stream information to each terminal.
The voice mixed stream information is pushed to each terminal through another path stream address applied before. And the terminal pulls the voice mixed stream information through the set stream address.
In the above process, besides realizing the voice call between the terminals, the PC browser side can also acquire voice call information and voice mixed stream information, and the specific implementation manner is the same as that of the terminals and is realized through two-way stream addresses. In this way, the user of the PC browser can also participate in an online call in the voice call room.
The above procedure is a principle description of live voice call, and on the basis of the above scheme, a method for managing users and terminals in an established voice call room (chat room) is described below. The user here refers only to the user accessing the MRC through the PC browser.
Typically, the user who is applying for the establishment of the chat room is taken as an administrator. The administrator has the right to invite other users, different users under the same organization can be invited to enter the same chat room, and when the administrator invites other users, the users need to be invited to enter after agreeing. When inviting the terminal in the chat room, the administrator does not need to confirm the terminal, and for the terminal which has entered the chat room, the administrator has the right to decide whether to agree when inviting the terminal in the chat room by other users, and if agreeing, the chat room immediately disconnects the terminal.
Meanwhile, based on the terminal information of entering the chat room acquired by the MRC, the user can view the chat room member list, and can execute the functions of wheat disabling, member deleting and the like for each member.
After the conversation of a certain chat room is completed, destroying the established chat room.
