When the sound card detects a path switching instruction for switching the interactive mode, namely, a path switching instruction corresponding to the main microphone, the sound card judges whether the third audio transmission path is in a disconnected state. The path switch command is triggered by the anchor headset in response to the anchor. Specifically, the connection and disconnection of the respective transmission paths may be achieved by switches. Referring to fig. 3, a switch 3 and a switch 4 are provided in the third audio transmission path, and the third audio transmission path is connected or disconnected by the switch 3 and the switch 4. It will be appreciated that when either switch 3 or switch 4 is in the closed state, the third audio transmission path is in the on state; when the switch 3 and the switch 4 are in the off state, the third audio transmission path belongs to the off state, that is, the sound card can determine whether the third audio transmission path is in the off state according to the states of the switch 3 and the switch 4. It will be appreciated that in fig. 3, two switches, switch 3 and switch 4, are provided in the third audio transmission path, but in other embodiments only one switch may be provided in the third audio transmission path.
Further, the audio transmission control method of the multi-channel live broadcast system further comprises the following steps:
and triggering a channel switching instruction corresponding to the main broadcasting headset after detecting that the main broadcasting corresponding to the main broadcasting headset presses a switching key triggering the channel switching instruction in the sound card.
The sound card is provided with a switching key for triggering the channel switching instruction, and a user can trigger the channel switching instruction by pressing the switching key, for example, the user can trigger the channel switching instruction by pressing the switching key for a short time or a long time. The switching key for triggering the channel switching instruction can also be arranged in the main microphone, and the operation of triggering the channel switching instruction by the switching key in the main microphone and the switching key in the sound card can be the same or different. The switch key in the main microphone may be a touch key or a press key. Therefore, after the sound card detects that the anchor corresponding to the anchor headset presses the switching key of the triggering channel switching instruction in the sound card, the channel switching instruction corresponding to the anchor headset is triggered. Further, if the anchor presses the switch button in the anchor headset, the anchor headset will send the detected channel switch command to the sound card, and the sound card receives the channel switch command sent by the anchor headset.
Further, in the sound card, can set up the hole of accomodating main broadcasting headset and assistant headset, in accomodating the hole, set up the interface that charges, after the headset is put into the hole of accomodating, can charge to the headset.
Step S200, generating a first control instruction, where the first control instruction is used to communicate with the third audio transmission channel, so that the main headset and the assistant headset perform audio data transmission through the third audio transmission channel.
If the third audio transmission path is in the disconnected state, the sound card generates a first control instruction, and the first control instruction is used for communicating the third audio transmission path to enable the main headset and the assistant headset to carry out audio data transmission through the third audio transmission path, namely, the main headset can be used for communicating with the assistant by the main headset at the moment, and the assistant can also be used for communicating with the main headset by the assistant headset at the moment. Specifically, the DSP in the sound card generates the first control instruction. It should be noted that, in the sound card, a terminal interface is further included, the terminal interface is used to connect a live broadcast terminal, the live broadcast terminal may be a mobile phone, a computer, a television, or the like, and the live broadcast terminal is used to share live broadcast content with devices held by viewers. When the main broadcasting headset and the assistant headset transmit audio data through the third audio transmission path, if the assistant headset is in the monitoring mode and does not want viewers to hear the conversation between the main broadcasting headset and the assistant headset, at this time, the connection between the live broadcasting terminal and the main broadcasting headset may be disconnected, and specifically, the switch currently in the closed state may be disconnected, for example, the switch 1 may be disconnected, so as to disconnect the connection between the live broadcasting terminal and the main broadcasting headset, that is, disconnect the first audio transmission path, so that the audio data received by the wireless 1 cannot be transmitted to the live broadcasting terminal through the terminal interface. If the assistant headset is not in the listening mode, i.e. the second audio transmission path between the assistant headset and the live terminal is connected, it is necessary to open the switch 1 and the switch 2 to disconnect the first audio transmission path and the second audio transmission path if the viewer does not want to hear the conversation between the main broadcast and the assistant. It should be noted that two switches may also be disposed in the first audio transmission path, where one switch is used to control the connection or disconnection of the path corresponding to the live broadcast terminal from the main broadcast headset, and the other switch is used to control the connection or disconnection of the path corresponding to the main broadcast headset from the live broadcast terminal; two switches can also be arranged in the second audio transmission path, wherein one switch is used for controlling the connection or disconnection of the path corresponding to the assistant headset for sending the audio data to the live broadcast terminal, and the other switch is used for controlling the connection or disconnection of the path corresponding to the assistant headset for sending the audio data to the live broadcast terminal.
Step S300, generating a second control instruction, wherein the second control instruction is used for disconnecting the third audio transmission channel and generating a third control instruction, the third control instruction is used for communicating the first audio transmission channel, establishing the connection between the main broadcasting headset and the live broadcasting terminal, and sending the audio data acquired by the main broadcasting headset to the live broadcasting terminal.
Further, when the main broadcasting headset and the live broadcasting terminal perform audio data transmission, the assistant headset is in a monitoring mode to monitor audio data transmitted by the main broadcasting headset and the live broadcasting terminal, and if the first audio transmission channel is detected to be in a disconnected state, a fourth control instruction is generated and used for communicating the second audio transmission channel and sending the audio data acquired by the assistant headset to the live broadcasting terminal.
And if the third audio transmission channel is in a connected state, the sound card generates a second control instruction, the second control instruction is used for disconnecting the third audio transmission channel, and after the third audio transmission channel is disconnected, the sound card generates a third control instruction, the third control instruction is used for connecting the first audio transmission channel and establishing the connection between the main broadcasting headset and the live broadcasting terminal. Specifically, the DSP in the sound card generates the second control instruction and the third control instruction. It will be appreciated that when either switch 3 or switch 4 is in the closed state, this indicates that a connection between the main headset and the live terminal is established, i.e. that the first audio transmission path is connected; when the switch 1 is in the off state, it indicates that the connection between the main headset and the live terminal is not established, i.e., the first audio transmission path is not connected. Specifically, when the connection between the anchor headset and the live broadcast terminal is established, it indicates that the communication path between the wireless 1 and the terminal interface is connected, and at this time, the audio data acquired by the anchor headset may be sent to the wireless 1 through the third wireless communication chip, and then the audio data is sent to the live broadcast terminal connected to the terminal interface by the wireless 1. Therefore, after the connection between the main broadcasting headset and the live broadcasting terminal is established, the sound card can send the audio data sent by the main broadcasting headset to the live broadcasting terminal. In this embodiment, when the main headset and the live terminal perform audio data transmission, the assistant headset is in a monitoring mode to monitor audio data transmitted by the main headset and the live terminal. When the assistant headset is in the listening mode, the assistant headset may receive audio data transmitted between the main broadcasting headset and the live broadcasting terminal, but the assistant headset may not transmit the audio data to the live broadcasting terminal. When the assistant headset is in listening mode, the assistant may or may not be present in the live room.
The sound card can detect whether the first audio transmission path is in a disconnected state in real time or in a timed mode. And if the sound card detects that the first audio transmission channel is in a disconnected state, the sound card generates a fourth control instruction, and the fourth control instruction is used for establishing a communication channel between the assistant headset and the live broadcast terminal, namely, communicating the second audio transmission channel. Specifically, the communication path between the assistant headset and the live terminal can be established by controlling the switch 2 to be in the closed state, that is, when the switch 2 is in the closed state, it indicates that the second audio transmission path between the assistant headset and the live terminal is established, that is, the second audio transmission path is connected; when the second switch 2 is in the off state, it indicates that the second audio transmission path between the assistant headset and the live terminal is not established. Wherein the fourth control instruction is generated by the DSP in the sound card. When the communication channel between the assistant headset and the live broadcast terminal is established, the assistant headset acquires the audio data sent by the assistant, the audio data are sent to the sound card through the second audio transmission channel, and then the sound card sends the received audio data to the live broadcast terminal, so that the audio data transmission between the assistant headset and the live broadcast terminal is realized. It will be appreciated that when audio data transmission between the assistant headset and the live terminal is effected, the user of the assistant headset becomes the anchor, instead of the user of the anchor headset, interacting with the audience.
Further, after step S300, the method further includes:
after the second audio transmission path is connected, if a connection command for connecting the third audio transmission path corresponding to the main headset is detected, the first audio transmission path and the second audio transmission path are disconnected, and step S200 is executed.
Further, when the assistant headset is in the listening mode, the communication path between the assistant headset and the live terminal is disconnected. In this embodiment, when the sound card receives a connection instruction for connecting the assistant headset and the live broadcast terminal, the sound card establishes a connection between the assistant headset and the live broadcast terminal according to the connection instruction, that is, connects the second audio transmission path. The connection command can be triggered by the assistant through a key on the assistant headset, or by the anchor through a key on the anchor headset, or by the anchor or the assistant through a key on the sound card. When the second audio transmission channel is communicated, the sound card detects whether a communication instruction corresponding to the main microphone and communicating the third audio transmission channel is detected. It should be noted that the connection command corresponding to the main broadcast headset means that the connection is triggered by the main broadcast through a key on the main broadcast headset or a key on the sound card. If the sound card detects a communication instruction corresponding to the main microphone, the sound card disconnects the connection between the main microphone and the live broadcast terminal and disconnects the connection between the assistant microphone and the live broadcast terminal, namely, the first audio transmission channel and the second audio transmission channel are disconnected, and the connection between the wireless 1 and the wireless 2 is established to connect the third audio transmission channel, so that the main microphone and the assistant microphone transmit audio data through the third audio transmission channel.
Further, if the sound card detects a connection instruction corresponding to the assistant headset, the sound card only disconnects the connection between the assistant headset and the live broadcast terminal, and does not disconnect the connection between the main broadcast headset and the live broadcast terminal, that is, only disconnects the second audio transmission channel and does not disconnect the first audio transmission channel. It should be noted that, in this embodiment, the permission of the connection command corresponding to the main headset is higher than that of the assistant headset, and the connection command corresponding to the main headset may disconnect the connection between the main headset and the live terminal or may disconnect the connection between the assistant headset and the live terminal, but the connection command corresponding to the assistant headset may only disconnect the connection between the assistant headset and the live terminal. And after the connection between the assistant headset and the live broadcast terminal is established, if the sound card does not receive the communication instruction, the current state is kept.
In this embodiment, the live broadcasting system includes a sound card, a main broadcasting headset, an assistant headset, and a live broadcasting terminal, the main broadcasting headset forms a first audio transmission channel with the live broadcasting terminal through the sound card, the assistant headset forms a second audio transmission channel with the live broadcasting terminal through the sound card, and the main broadcasting headset forms a third audio transmission channel with the assistant headset through the sound card.
