Referring to fig. 1, a flow chart of a multipath sound control method according to an embodiment of the present disclosure is schematically illustrated, and specifically includes the following steps:
The step aims at determining the number of the current screen projection ends. In the screen transmission and projection process, the screen transmission and projection is generally initiated by a screen projection end, and a receiving end receives signals and projects the screen. The receiving end can receive the screen projecting signal of at least one screen projecting end, so that after a new screen projecting end is accessed, the number of the accessed screen projecting ends needs to be counted, and the number of the accessed screen projecting ends which are connected with the receiving end is detected. Therefore, whether the transmission network formed by all the screen projection ends and the receiving ends is single-ended or multi-ended is judged.
And 102, when the number is more than one, indicating the accessed screen projection end which is transmitting the sound information to stop collecting the sound information.
The method comprises the following steps that under the condition that a receiving end judges that a plurality of accessed screen projecting ends exist, a sound closing instruction is sent to the accessed screen projecting ends which are transmitting sound, and the accessed screen projecting ends stop collecting and transmitting sound.
The transmission content of the screen projection may or may not include sound for the accessed screen projection terminals, and therefore, when a plurality of screen projection terminals are detected, stopping of sound information collection may be instructed to all screen projection terminals, or stopping of sound information collection may be instructed only to the screen projection terminals that are performing sound transmission. The process of sending the indication may then be via a wired connection or via a wireless connection.
The step aims to indicate the corresponding screen projection end to start the collection and transmission of the sound information through the selection of a user. The selection instruction is selection information of a user for a currently accessed screen projection end, and the selection instruction points to at least one screen projection end. And generating a voice starting instruction by the receiving end according to the selection instruction, and sending the voice starting instruction to the corresponding screen projection end to enable the screen projection end to start to collect and transmit voice.
And 104, acquiring and outputting the sound information of the appointed screen projection end.
This step is intended for the receiving end to output the received sound information. According to different application scenes and implementation requirements, the specific output mode of the sound information can be flexibly selected.
For example, for an application scenario in which the method of the present embodiment is executed on a single device, the sound information may be output in a sound manner directly on a sound playing component (a sound, a play-out device, etc.) of the current device, so that an operator of the current device can directly hear the content of the sound information through the sound playing component.
For another example, for an application scenario executed on a system composed of multiple devices by the method of this embodiment, the sound information may be sent to other preset devices serving as receivers in the system through any data communication manner (e.g., wired connection, NFC, bluetooth, wifi, cellular mobile network, etc.), so that the preset devices receiving the sound information may perform subsequent processing on the sound information. Optionally, the preset device may be a preset server, and the server is generally arranged at a cloud end and used as a data processing and storage center, which can store and distribute the sound information; the receiver of the distribution is a terminal device, and the holders or operators of the terminal devices may be users, other participants, other viewers watching the screen projection, and the like.
For another example, for an application scenario executed on a system composed of multiple devices, the method of this embodiment may directly send the sound information to a preset terminal device through any data communication manner, where the terminal device may be one or more of the foregoing paragraphs.
A multipath sound control method provided by applying one or more embodiments of the present specification, includes: detecting the number of accessed screen projection ends after a new screen projection end is accessed; when the number is more than one, indicating the accessed screen projection end which is transmitting the sound information to stop collecting the sound information; acquiring a selection instruction of a user, determining a designated screen projection end selected by the user from accessed screen projection ends according to the selection instruction, and indicating the designated screen projection end to start the collection and transmission of sound information; and acquiring and outputting the sound information of the appointed screen projection end. One or more embodiments of this description are based on the control to throwing the screen end, under the circumstances that the screen was thrown to the multichannel, guarantee that only user's appointed throw the screen end sound and open to prevent the confusion that a plurality of sound broadcast overlapped each other simultaneously and cause, very big promotion user experience, simultaneously, because sound is controlled from the source, consequently saved the consumption of sound transmission, can save the network bandwidth, can save the sending terminal resource.
In an optional embodiment of the present description, in order to save network resources when a new screen projection end needs to access, the operation process of the subsequent steps is simplified, and the overall efficiency is improved. After a new screen projection end is accessed, the method further comprises the following steps:
acquiring a screen projection request of a newly accessed screen projection end;
receiving and playing the image information of the newly accessed screen projection end according to the screen projection request;
and indicating the newly accessed screen projection end to stop collecting the sound information.
The screen transmission and screen projection process is generally initiated by a screen projection end, and a receiving end receives signals and projects the screen. And then the screen projection request is an admission request sent by the screen projection end to the receiving end for projecting the screen at the receiving end, the receiving end establishes a channel between the receiving end and the screen projection end after receiving the screen projection request, and the screen projection end transmits pictures and/or sound through the channel.
After receiving the screen projection request, the receiving end starts to acquire image information of the screen projection end and performs image transmission, where the image transmission may be wired transmission, wireless transmission, or the like. Meanwhile, the existing screen projection end generally transmits image and sound information at the same time, and then in order to save network resources, the receiving end sends a sound stop instruction to the screen projection end to instruct the screen projection end to stop collecting sound information, so that network resources cannot be occupied for transmitting the sound information.
In other specific application scenes, a screen projection sending end is connected to a receiving end to start screen projection; the screen-casting sending end can be defaulted not to collect and transmit sound when being connected. Therefore, sound transmission can not be carried out when the screen projection terminal is accessed, the bandwidth required by sound transmission is reduced, and sound information is controlled from the source.

When a single line of screen projection is carried out (namely, only one screen projection end carries out screen projection), a user generally needs the sound playing of the screen projection, and then when the receiving end finds the situation, the receiving end automatically sends a sound starting instruction to the screen projection end to enable the receiving end to start sound collection and data pushing.
In an optional embodiment of the present specification, in order to ensure that when the user selects the screen-projected full-screen playing, the sound corresponding to the screen projection is continuously played. After the sound information of the appointed screen projection end is obtained and output, the method further comprises the following steps:

and when a screen projecting request of a newly accessed screen projecting end is acquired, maintaining full-screen display and indicating the newly accessed screen projecting end to stop sound information acquisition.
In a specific application scenario, a user selects one of a plurality of screen projection devices to display the full screen, at this time, a receiving end sends a sound opening instruction to a sending end of the full screen display and plays image information of the full screen display, at this time, the screen projection device opens a sound collection module after receiving the sound opening instruction, and sound collection and data push are started. And when a new screen is switched in the receiving end, the receiving end maintains full-screen display, and directly indicates the newly switched-in screen-throwing end to stop collecting sound information, and image information is played in a background.
In an optional embodiment of the present specification, in order to enable a user to know the relevant situation of a new screen projection end when the new screen projection end is accessed in a full screen situation. When a screen projection request of a newly accessed screen projection end is acquired, the method further comprises the following steps:
generating a temporary image frame in a full screen display picture;
and playing the image information of the newly accessed screen projection end through the temporary image frame.
In a specific application scenario, the temporary image frame is a small frame body for playing image information of the screen-projecting end, and may be embedded in the full-screen image, or may float on the full-screen image, and the like, and the temporary image frame may be set at a corner of the full-screen image, and may only have a set time (e.g., 30 seconds, and the like), and a user may view specific image information of the newly-accessed screen-projecting end through the temporary image frame.
In an alternative embodiment of the present specification, in order to play the sound information of a new screen projection terminal under a specific condition when the new screen projection terminal is accessed in the full screen condition. After the image information of the newly accessed screen projection end is played through the temporary image frame, the method further comprises the following steps:
and when the selection information of the user on the temporary image frame is acquired, indicating the newly accessed screen projection end to start the collection and transmission of sound information according to the selection information.
In a specific application scenario, when a user thinks that a newly-accessed screen projection end also needs to play sound, the user can select a temporary image frame, and at the moment, the temporary image frame can be converted into a permanent image frame, and collection and transmission of sound information are started. After the sound of the newly accessed screen projection end is started, the previous full-screen projection end can exit the full-screen state or not, and the sound can be closed or not. The person skilled in the art can flexibly adjust the method according to the actual application scenario.
In alternative embodiments of the present description, the user's control of the receiving end may be either close range or remote in order to accommodate multiple modes of operation. The acquiring of the selection instruction of the user comprises:
