Example 1
According to an embodiment of the present application, there is provided an embodiment of a method for playing multimedia data, it should be noted that the steps shown in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order different from that shown or described herein.
Fig. 1 is a flowchart of an alternative method for playing multimedia data according to an embodiment of the present application, as shown in fig. 1, the method includes the following steps:
step S102, determining a first screen currently occupying the focus of the sound source and a second screen needing to play the multimedia data from a plurality of screens on the vehicle.
The vehicle can be a new energy electric vehicle, a traditional oil vehicle or the like, and the type of the vehicle is not particularly limited in the application. Optionally, the vehicle may include a plurality of screens, where the plurality of screens may be at least two of a vehicle center control screen, a co-driver screen on the vehicle, and a rear-row screen of the vehicle, and the rear-row screen of the vehicle may be one or more.
The first screen may be a screen on a vehicle on which multimedia data is being played, where the multimedia data may include data information such as weather forecast, popular music, broadcast, and the like, and optionally, the multimedia data includes audio. Alternatively, the first screen may be one of a center control screen of the vehicle, a co-driver screen of the vehicle, and a rear-row screen of the vehicle.
The second screen may be one of a center control screen of the vehicle, a co-driver screen of the vehicle, and a rear-row screen of the vehicle.
In an alternative embodiment, the first screen currently occupying the focus of the audio source may be determined according to the display condition of the multimedia data of the different screens on the current vehicle or according to the audio source playing condition of the multimedia data of the different screens on the current vehicle. Further, the second screen on which the multimedia data needs to be played may be determined according to an indication situation of a user on the vehicle, where the user on the vehicle may include people riding at different positions on the vehicle, optionally, the user on the vehicle may instruct different screens on the vehicle to play the multimedia data by pressing different keys on the vehicle body, or instruct different screens on the vehicle to play the multimedia data by pressing virtual keys on different screens on the vehicle, or instruct different screens on the vehicle to play the multimedia data by voice control.
Taking the following as an example for explanation, in the process of driving the vehicle, assuming that the central control screen on the vehicle is playing navigation information, the central control screen playing navigation information can be determined to be a first screen, alternatively, at this time, a passenger sitting in the back row of the vehicle clicks a key on the back row screen of the vehicle to instruct the back row of the vehicle to play popular music, and then the back row screen needing to play popular music can be determined to be a second screen.
Step S104, determining a first playing mode corresponding to the first screen and a second playing mode corresponding to the second screen.
The first playing mode may be a speaker playing mode or an earphone playing mode, where the earphone may include a bluetooth earphone and a wired earphone.
The second playing mode may be a speaker playing mode or an earphone playing mode, where the earphone may include a bluetooth earphone and a wired earphone.
In an alternative embodiment, the playing mode of the audio source of the multimedia data of the front-row screen of the vehicle, that is, the playing mode of the audio source of the multimedia data of the center control screen or the co-driver screen may be a speaker playing mode, and the playing mode of the audio source of the multimedia data of the rear-row screen of the vehicle may be a speaker playing mode, or an earphone playing mode. Therefore, when the first screen is the center control screen or the co-driver screen, the first playing mode of the first screen can be considered as a loudspeaker playing mode, and when the first screen is the rear-row screen of the vehicle, the playing mode of the first screen can be determined according to the playing source of the sound source on the first screen and the connection condition of the earphone on the first screen. Similarly, when the second screen is a center control screen or a co-driver screen, the second playing mode of the second screen can be considered to be a speaker playing mode, and when the second screen is a rear-row screen of the vehicle, the playing mode of the second screen can be determined according to the playing source of the sound source on the second screen and the connection condition of the earphone on the second screen.
For the following explanation, it is assumed that a screen on the vehicle that is playing multimedia data is a co-driver screen on the vehicle, where the co-driver screen on the vehicle is playing a weather forecast in a speaker manner, and at this time, a driver on the vehicle instructs the central control screen on the vehicle to play navigation information in a speaker manner by clicking a key on the central control screen of the vehicle, so that it may be determined that a first play manner corresponding to the co-driver screen on the first screen is a speaker play manner, and it may be determined that a second play manner corresponding to the central control screen on the second screen is a speaker play manner.
Step S106, based on the first playing mode and the second playing mode, determining whether the second screen is preempted in the focus of the audio source, and controlling the second screen to play the multimedia data.
In an alternative embodiment, after the first playing mode corresponding to the first screen and the second playing mode corresponding to the second screen have been determined, it may be determined whether the first playing mode corresponding to the first screen is the same as the second playing mode corresponding to the second screen. When the first playing mode corresponding to the first screen is the same as the second playing mode corresponding to the second screen, the second screen may be required to capture and preempt the audio focus occupied by the first screen, and when the first playing mode corresponding to the first screen is different from the second playing mode corresponding to the second screen, it is indicated that playing of the multimedia data on the first screen will not affect playing of the multimedia data on the second screen, so that preempting of the multimedia data on the second screen is not required.
For the following description, it is assumed that the first screen is a central control screen on a vehicle, where the first screen is playing navigation information in a speaker playing mode, and the second screen is a co-driver screen on the vehicle, where the second screen needs to play short videos in a speaker playing mode. Optionally, because the mode of playing the navigation information by the central control screen and the mode of playing the audio source of the multimedia data of the co-driver screen are both speaker playing modes, the second screen needs to preempt the audio source focus, so that the second screen can normally play the multimedia data, and at this time, the first screen stops playing the multimedia data because the audio source focus occupied by the first screen is preempted.
The first screen is assumed to be a central control screen on the vehicle, wherein the first screen is playing popular music in a loudspeaker playing mode, and the second screen is a rear screen on the vehicle, wherein the second screen needs to play movies in an earphone playing mode. Optionally, since the second playing mode of the second screen is an earphone playing mode, the playing of the multimedia data by the first screen does not affect the playing of the multimedia data by the second screen, so that the second screen does not need to preempt the focus of the audio source, only the second screen is controlled to play the multimedia data in an earphone playing mode, and meanwhile, the playing state of the playing of the multimedia data by the first screen is not changed, that is, the first screen can play popular music in a loudspeaker playing mode.
Through the steps, a first screen currently occupying the focus of the sound source and a second screen needing to play the multimedia data are determined in a plurality of screens on the vehicle; determining a first playing mode corresponding to the first screen and a second playing mode corresponding to the second screen; and determining whether the second screen occupies the focus of the sound source or not based on the first playing mode and the second playing mode, and controlling the second screen to play the multimedia data. It is easy to note that the first playing mode of the first screen which occupies the audio focus and the second playing mode of the second screen which needs to play the multimedia data can be determined first, so that whether the audio is required to be preempted or the second screen can be directly controlled to play the multimedia data can be determined according to whether the first playing mode and the second playing mode are the same, thereby avoiding the confusion situation of the audio focus when the multimedia data are played by different screens, and further solving the technical problem that the audio focus is disordered when a plurality of screens on a vehicle play the audio simultaneously in the related art.
Optionally, determining whether the second screen preempts the audio focus based on the first playing mode and the second playing mode includes: determining a first screen position of the first screen and a second screen position of the second screen; determining that the second screen occupies the focus of the sound source in response to the first screen position and the second screen position being preset positions; and determining whether the second screen preempts the sound source focus based on the first playing mode and the second playing mode in response to the first screen position and the second screen position being not preset positions.
The first screen position may be a front-row position of the vehicle, or a rear-row position of the vehicle.
The second screen position may be a front-row position of the vehicle, or a rear-row position of the vehicle.
The above-mentioned preset position may be a front-row position of the vehicle, that is, the preset position may be a center control screen or a co-driver screen, and optionally, when the first screen position and the second screen position are preset positions, the first screen may be one of the center control screen and the co-driver screen, and the second screen may be the other of the center control screen and the co-driver screen different from the first screen.
In an optional embodiment, since the audio playing modes adopted on the vehicle central control screen and the vehicle co-driver screen are both speaker playing modes, optionally, the first screen is assumed to be the co-driver screen, the second screen is assumed to be the central control screen, since the first screen is currently playing the audio of the multimedia data in a speaker mode, and since the co-driver screen also needs to use the speaker playing mode to play the audio of the multimedia data, the second screen needs to preempt the audio focus occupied by the first screen, so that the second screen can normally play the multimedia data, and optionally, when the second screen normally plays the multimedia data, the first screen needs to stop playing because the first screen does not occupy the audio focus any more.
In another alternative embodiment, it is assumed that neither the first screen nor the second screen is a screen on the front row of the vehicle, i.e. neither the first screen nor the second screen is a vehicle center control screen, or a co-driver screen, and therefore both the first screen and the second screen are rear row screens of the vehicle. Optionally, the audio source playing mode of the multimedia data on the rear-row screen of the vehicle may be a speaker playing mode or an earphone playing mode, so when it is determined that the first screen and the second screen are both rear-row screens of the vehicle, a specific audio source playing mode adopted by the first screen and the second screen needs to be further determined, and when the audio source playing modes adopted by the first screen and the second screen are the same and are both speaker playing modes, the second screen needs to preempt the audio source focus.
For the following explanation, it is assumed that the first screen and the second screen are rear-row screens of the vehicle, the sound source playing mode adopted by the first screen is an earphone playing mode, and the sound source playing mode adopted by the second screen is a speaker playing mode, and since playing the multimedia data on the first screen will not affect playing the multimedia data on the second screen, the first screen can continue playing the multimedia data according to the original playing mode, and the second screen is controlled to play the multimedia data in the speaker playing mode. The first screen and the second screen are both rear-row screens of the vehicle, and the sound source playing modes adopted by the first screen and the second screen are earphone playing modes, so that the first screen plays multimedia data without affecting the second screen plays multimedia data, and the second screen is not required to preempt the sound source focus. Optionally, it is assumed that the first screen and the second screen are both rear-row screens, and when the audio source of the multimedia data needs to be played by adopting a speaker playing mode, the second screen is required to preempt the audio source focus.
Optionally, determining whether the second screen preempts the audio focus based on the first playing mode and the second playing mode includes: and responding to the difference between the first playing mode and the second playing mode, and determining that the second screen does not preempt the focus of the sound source.
In an alternative embodiment, when the first playing mode adopted by the first screen is the same as the second playing mode adopted by the second screen and is not the earphone playing mode, the second screen is required to take the preemptive audio focus, so that the second screen can normally play video, when the first playing mode adopted by the first screen is different from the second playing mode adopted by the second screen, the second screen does not need to take the preemptive audio focus, and meanwhile, the first screen can continue playing the multimedia data according to the original playing mode, and the second screen can also play the multimedia data according to the required mode.
Optionally, the method further comprises: responding to the second screen to preempt the focus of the audio source, and controlling the first screen to stop playing the currently played multimedia data; and controlling the first screen to continuously play the currently played multimedia data in response to the fact that the second screen does not preempt the audio focus.
In an alternative embodiment, when the first playing mode adopted by the first screen is the same as the second playing mode adopted by the second screen and neither is the earphone playing mode, the second screen is required to take the preemptive audio focus, and optionally, since the audio focus currently occupied by the first screen is preempted, the multimedia data being played on the first screen is stopped. When the first playing mode adopted by the first screen and the second playing mode adopted by the second screen are adopted, the second screen does not need to preempt the audio focus, so that the audio focus occupied on the first screen can be kept, and the first screen can continue to play the multimedia data according to the original mode.
For the following explanation, it is assumed that the first screen is a rear-row screen of the vehicle, and the first screen plays short videos by using a speaker playing mode, and it is assumed that the second screen is also a rear-row screen of the vehicle, and the second screen needs to play popular music by using a speaker playing mode, and optionally, since the first screen and the second screen need to play multimedia data in the same mode, the second screen needs to preempt the audio focus, and further, since the audio focus is occupied by the second screen, the first screen will stop playing currently played multimedia data. Optionally, the first screen is a rear-row screen of the vehicle, and the first screen adopts an earphone playing mode to play the short video, and the second screen is also a rear-row screen of the vehicle, and needs to adopt an earphone playing mode to play popular music.
Optionally, in response to the second screen preempting the audio source focus, the method further comprises: controlling a first screen to play a sound source focus; and controlling the second screen to occupy the sound source focus in response to the first screen successfully releasing the sound source focus.
In an alternative embodiment, assuming that it has been determined that the second screen needs to preempt the audio focus, since the audio focus is currently occupied by the first screen, the audio focus needs to be released first by the first screen, optionally, the user in front of the second screen on the vehicle may play the multimedia data on the second screen in any mode, after the vehicle system receives the user request, it may determine that the user wants to use the playing mode of the multimedia data on the second screen, optionally, the playing mode of the multimedia data on the second screen that the user wants to use may be compared with the playing mode of the multimedia data on the first screen, where the playing mode of the multimedia data on the second screen that the user wants to use is the same as the playing mode of the multimedia data on the first screen, and in case that neither is the playing mode of the earphone, the first screen may be controlled to release the audio focus. Further, after the vehicle-mounted system detects that the first screen has successfully released the audio source focus, the second screen can be controlled to take the preemptive audio source focus. Optionally, the first screen is controlled to release the sound source focus, and the second screen is controlled to preempt the sound source focus, so that disorder of the system can be avoided, and the technical problem that the sound source focus is disordered when a plurality of screens on a vehicle play the sound source simultaneously in the related art is solved.
Optionally, determining the first playing mode corresponding to the first screen and the second playing mode corresponding to the second screen includes: determining a first screen position of the first screen and a second screen position of the second screen; responding to the first screen position as a preset position and the second screen position as a preset position, and determining that the first playing mode and the second playing mode are both speaker playing modes; determining that the first playing mode is a loudspeaker playing mode or an earphone playing mode according to the fact that the first screen position is not the preset position; and determining that the second playing mode is a loudspeaker playing mode or an earphone playing mode according to the fact that the second screen position is not the preset position.
In an alternative embodiment, since the audio playing mode of the multimedia data of the front-row screen of the vehicle is a speaker playing mode, and the audio playing mode of the multimedia data of the rear-row screen of the vehicle is a speaker playing mode or an earphone playing mode, when determining the first playing mode adopted by the first screen and the second playing mode adopted by the second screen, the positions of the first screen and the second screen can be determined first, and the first playing mode adopted by the first screen and the second playing mode adopted by the second screen can be estimated primarily according to the positions of the first screen and the second screen. If the position of the first screen or the second screen is the front-row position of the vehicle, the audio playing mode of the multimedia data corresponding to the first screen or the second screen can be rapidly determined to be a loudspeaker playing mode, and if the position of the first screen or the second screen is the rear-row position of the vehicle, further step-by-step judgment needs to be performed on the first playing mode adopted by the first screen and the second playing mode adopted by the second screen.
Optionally, determining that the first playing mode is a speaker playing mode or an earphone playing mode includes: determining the on-off state of a speaker or an earphone on a first screen; responding to the switch state of the loudspeaker as a preset state, and determining that the first playing mode is a loudspeaker playing mode; and responding to the switch state of the earphone as a preset state, and determining that the first playing mode is an earphone playing mode.
The rising preset state may be an open state.
In an alternative embodiment, when determining the playing modes of the audio sources when the first screen and the second screen play the multimedia data, the playing modes of the audio sources when the first screen and the second screen play the multimedia data may be determined by determining the on-off states of the corresponding speakers and headphones on the first screen and the second screen, so that the playing modes of the audio sources when the first screen and the second screen play the multimedia data may be determined according to the on-off states of the corresponding speakers and headphones on the first screen and the second screen. Optionally, assuming that the state of the speaker corresponding to the first screen is an on state, it may be determined that the playing mode of the audio source when the first screen plays the multimedia data is a speaker playing mode. Optionally, assuming that the state of the earphone corresponding to the second screen is an on state, it may be determined that the playing mode of the audio source when the second screen plays the multimedia data is an earphone playing mode.
Fig. 2 is a schematic diagram of playing an alternative multimedia data according to an embodiment of the present application, as shown in fig. 2, assuming that a screen on a vehicle includes a center control screen, a co-driver screen, a rear row a, and a rear row B, the current audio focus may be first identified. If the current sound source focus is occupied by the central control screen, judging whether the preemption of the sound source focus is needed, and if the second screen is a secondary control screen, releasing the sound source focus by the central control screen, preempting the sound source focus by the secondary control screen, and outputting the sound source by a loudspeaker so that the second screen plays multimedia data. Optionally, if the second screen is a rear-row screen, it is required to determine whether the rear-row screen is connected with the earphone, if the rear-row screen is not connected with the earphone, the central control screen is required to release the sound source focus, the rear-row screen preemptively occupies the sound source focus, the speaker outputs the sound source to enable the second screen to play the multimedia data, if the rear-row screen is connected with the earphone, the sound source content of the rear-row screen is output by the earphone, and the central control screen sound source keeps the speaker output.
Further, if the current sound source focus is occupied by the rear row a, it is required to determine whether preemption of the sound source focus is required, alternatively, if the second screen is a central control screen or a co-driver screen, it is required to determine whether the rear row a is connected with headphones, if the rear row a is not connected with headphones, then the rear row a is required to release the sound source focus, the central control screen or the co-driver screen preempting the sound source focus, sound of the second screen is output by a speaker, if the rear row a is connected with headphones, sound source content of the rear row a is output by the headphones, the central control screen or the co-driver screen preempting the sound source focus, and sound source of the second screen is output by the speaker. Assuming that the second screen is the rear row B, it is necessary to determine whether the rear row a and the rear row B are connected to headphones, respectively. When the rear row A is not connected with the earphone, the rear row B is connected with the earphone, the audio content of the rear row B is output from the earphone, the audio content of the rear row A is still output by the loudspeaker, when the rear row A is not connected with the earphone, the rear row B is also not connected with the earphone, the audio focus of the rear row A needs to be controlled, the rear row B occupies the audio focus, and the audio content of the second screen is output by the loudspeaker.
