At present, the android layer mute mechanism of the smart television calls the same mute interface for a plurality of applications at the same time. This muting mechanism may cause the following problems: the mute/un-mute instructions of different applications affect each other, and finally the sound state of the smart tv is not the sound state required by the user. Specifically, as shown in fig. 2, if the android layer muting mechanism of the smart television adopts the existing logic: at the time t1, acquiring a mute request of an application 1 in an android layer of the smart television from the mobile terminal, and muting the smart television; at a time t2, acquiring a mute request of the application 2 from the mobile terminal, wherein the smart television keeps a mute state; at time t3, when the un-mute request of application 1 is received from the mobile terminal, application 2 wants the smart tv to keep the mute state, but is affected by un-mute of application 1, so that the mute/un-mute commands of different applications are affected with each other, and finally the sound state of the smart tv is not the sound state required by the user.
An embodiment of the present invention provides a volume adjusting method, as shown in fig. 3, including the following steps:
s301, acquiring a mute release request of a first application from the mobile terminal;
s302, removing the first application from a mute list according to a mute release request of the first application;
s303, judging whether other applications exist in the mute list or not;
s304, if other applications exist in the mute list, keeping the smart television mute.
Specifically, as shown in fig. 2, if the android layer muting mechanism of the smart television adopts the logic of the above method: at the time t1, acquiring a mute request of an application 1 in an android layer of the smart television from the mobile terminal, and muting the smart television; at a time t2, acquiring a mute request of the application 2 from the mobile terminal, wherein the smart television keeps a mute state; at time t3, although the un-mute request for app 1 is acquired from the mobile terminal and app 1 is removed from the mute list, app 2 still exists in the mute list and thus the smart tv mute state will still be maintained. Therefore, the mute removing instruction of the application 1 cannot influence the mute state of the application 2, the smart television cannot remove the mute state, and the mute requirements of a plurality of applications can be met.
Here, if the smart television mute state is released if no other application exists in the mute list after the un-mute request of application 1 is acquired from the mobile terminal and application 1 is removed from the mute list at time t 3.
As shown in fig. 4, a specific implementation process of the method may be: after acquiring a mute request of the application 1 from the mobile terminal, the application 1 initiates a mute application by calling an AcquireMute interface in a mute state judgment layer. Under the condition of applying for mute, after the platform mute state judgment layer receives the mute application of the application 1, the application 1 is added into the mute list, and a mute interface corresponding to the application 1 in the middleware is called, at the moment, the application 1 hopes that the smart television is muted. After acquiring the mute release request of the application 1 from the mobile terminal, the application 1 initiates the mute release request by calling a releasemenu interface in the mute state judgment layer. Under the condition of removing the mute, after the platform mute state judgment layer receives a mute removing request of the application 1, the application 1 is deleted from the mute list, and the mute interface corresponding to the application 1 is released. And if no other applications except the application 1 exist in the current mute list, the mute state of the intelligent television is released. And if the application 2 exists in the current mute list in addition to the application 1, keeping the mute state of the intelligent television.
An embodiment of the present invention further provides a volume adjusting method, as shown in fig. 5, including the following steps:
s501, a mute request of a second application is acquired from the mobile terminal;
s502, adding the second application into a mute list according to the mute request of the second application;
s503, judging whether the process of the second application is in a survival state;
s504, if the process of the second application is not in a survival state and other applications do not exist in the mute list, removing the second application from the mute list so as to mute the smart television.
Specifically, after the mute request of the second application is acquired from the mobile terminal, it may be determined whether the second application exists in the mute list, and if the second application does not exist in the mute list, the second application is added to the mute list. And then periodically judging whether the process of the second application is in a survival state, and if the process of the second application is not in the survival state and other applications do not exist in the mute list, removing the second application from the mute list so as to mute the smart television. In this way, if the application special case exits abnormally without releasing the mute, the application can be actively removed from the mute list, thereby preventing the occurrence of the un-mute condition caused by the abnormal exit of the application.
As shown in fig. 6, a specific implementation process of the method may be: after the socket server is started, the waiting client is started to be connected, a mute request/a mute release request of a system or a third-party application is obtained from the mobile terminal, a mute interface/a mute release interface corresponding to the application is called, and the socket client uniquely corresponding to the application is established by the platform mute state judgment layer.
After the socket client side is established to be connected with the server side, TID information of the process of the application, current request content (mute/unmute) and information of whether the process is alive or not are sent to the server side at regular time, and the server side judges whether the process of the application is in a alive state or not according to the information. If the process of the application is not in a survival state, the application can be judged to be in an abnormal state, and if no other application exists in the mute list, the mute interface corresponding to the application in the mute list is released so as to enable the mute of the smart television to be released.
Here, the process information of the second application is periodically acquired from a socket client corresponding to the second application. The acquisition may be performed every 5S, and the specific time is selected according to the resource size of the application itself.
An embodiment of the present invention further provides a volume adjusting method, as shown in fig. 7, including the following steps:
s701, acquiring a play operation request of the voice assistant application from the mobile terminal;
s702, playing the voice assistant application and carrying out mute processing on all applications except the voice assistant application.
The voice assistant is an application with more use scenes at present, so the method does not call a mute interface to mute and unmute the voice assistant application any more, but calls an acquireplay interface and a releaseplay interface. As shown in fig. 8. The playing operation request of the voice assistant application can be obtained from the mobile terminal, and after the playing interface is called according to the playing state interface logic, all applications except the voice assistant application are muted when the voice assistant application is in the playing state. Thereby preventing other applications from interfering with the playback of the voice assistant. The method can also obtain a play stopping request of the voice assistant application from the mobile terminal, and after the play stopping interface is called according to the play state interface logic, the voice assistant stops playing or the state information is not sent after time out, all mute interfaces are released according to the mute interface logic, and the mute of the intelligent television is released, so that the silent condition of the intelligent television is avoided.
