Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Currently, with the progress of science and technology, most electronic devices can play audio data. The audio architecture of electronic devices is similar to that of computers, and is mainly implemented by a processor and a built-in audio CODEC (coder-decoder). Specifically, the processor receives the input of audio data, converts the audio data into an I2S (Inter-IC Sound, integrated circuit built-in audio bus) signal, transmits the signal to the CODEC, converts the signal into an analog signal, and plays the signal.
With the further development of scientific technology and the increase of the demands of users, the electronic equipment can be connected with external audio playing equipment, and audio data can be played through the audio playing equipment. The audio playing device may include earphones, a sound box, a vehicle-mounted device and the like. The audio playing device connected with the electronic device can receive the audio data transmitted by the electronic device and play the audio data. The electronic device can be connected with the audio playing device in a wired mode or a wireless mode.
At present, users usually connect audio playing devices with electronic devices in a wireless manner to realize that the audio playing devices play audio data. When the audio playing device is wirelessly connected with the electronic device, the electronic device and the audio playing device connected with the electronic device need to use a network to perform data transmission. For example, the electronic device and the audio playing device need to use a Wireless Fidelity (WiFi) connection for data transmission, or the electronic device and the audio playing device need to use a Bluetooth (BT) connection for data transmission, etc. In most cases, the electronic device can be connected with the audio playing device through bluetooth, and transmit audio data to the audio playing device through bluetooth for playing.
However, since the electronic device transmits the audio data to the audio playing device and there is a certain transmission delay until the audio playing device receives the audio data, the sound played by the audio playing device may not be synchronized with the picture displayed by the electronic device, resulting in poor user experience.
In view of the above problems, the inventor has studied and proposed a display control method, an apparatus, an electronic device, and a storage medium provided in the embodiments of the present application for a long time, and by obtaining a transmission delay time for transmitting audio data from an audio playing device to the audio playing device and then performing delay display on a dynamic picture according to the transmission delay time, the dynamic picture played by the electronic device is synchronized with a sound played by the audio playing device, so as to improve user experience. The specific display control method is described in detail in the following embodiments.
In an embodiment, please refer to fig. 1, and fig. 1 is a schematic flowchart illustrating a display control method according to an embodiment of the present disclosure. The display control method delays the display of the dynamic picture according to the transmission delay time of transmitting the audio data to the audio playing device by the electronic device when the picture displayed by the electronic device is the dynamic picture. In a specific embodiment, the display control method is applied to the display control apparatus 400 shown in fig. 6 and an electronic device (fig. 7) provided with the display control apparatus 400. The specific flow of the embodiment will be described below by taking an electronic device as an example, and it is understood that the electronic device applied in the embodiment may be a smart phone, a tablet computer, a wearable electronic device, a vehicle-mounted device, an intelligent gateway, and the like, and is not limited specifically herein. As will be described in detail with respect to the flow shown in fig. 1, the display control method described above may specifically include the following steps:
step S110: when the electronic equipment displays the dynamic picture, detecting the connection state between the electronic equipment and other equipment.
Electronic devices are often used to play a dynamic image, and the electronic devices simultaneously play audio data corresponding to the dynamic image while playing the dynamic image. The dynamic picture refers to a picture in which a graphic in the picture changes with time, and the static picture is a picture in which a graphic in the picture does not change with time, as opposed to the dynamic picture. For example, the dynamic picture may include a video picture, a game picture, and the like.
At present, electronic devices often transmit audio data corresponding to the dynamic picture to an audio playing device for playing by connecting the audio playing device. And for the user with higher demand, the Bluetooth function of the electronic equipment can be utilized, so that the audio playing equipment is connected with the electronic equipment through Bluetooth, and the audio data can be played. When the electronic device transmits the audio data corresponding to the dynamic picture to the audio playing device for playing through bluetooth communication, there will be a transmission delay of the audio data, so that when the electronic device displays a picture, the audio playing device does not receive the audio data of the picture, resulting in asynchronous playing of the picture and playing of the sound, and this situation can be handled.
In this embodiment of the application, first, when the electronic device displays a dynamic picture, the connection state between the electronic device and another device may be detected, so that when the electronic device displays the dynamic picture, the situation that the audio playing device connected to the electronic device via bluetooth plays audio data is used for processing.
The connection state between the electronic device and the other device includes the existence of communication connection between the other device and the electronic device, the communication connection mode between the other device and the electronic device, the absence of communication connection with the other device, the communication connection with the other device, and the like. When the electronic device is in the connected state, the electronic device may be in a mobile network connected state, for example: when other devices are in communication connection with the electronic device, the connection mode may be a WiFi (WIreless-Fidelity) connection, a bluetooth connection, a MiFi (Mobile WiFi, Mobile router, or Mobile hotspot) connection, or the like. In the embodiment of the present application, a communication connection state between a specific electronic device and another device is not limited.
Step S120: and when the audio playing device is connected with the electronic device through the Bluetooth, acquiring the transmission delay time of the audio playing device from the electronic device to the audio data.
In the embodiment of the application, the electronic device can be connected with other devices through Bluetooth. Therefore, when the other device is connected to the electronic device through bluetooth or the electronic device is connected to the other device through bluetooth, step S110 may detect that there is bluetooth connection between the other device and the electronic device. For example, when the bluetooth functions of the electronic device and other devices are detected in step S110, and the electronic device is successfully paired with other devices that turn on the bluetooth functions, it may be determined that there is another device connected to the electronic device through bluetooth.
Furthermore, the device type of other devices connected with the electronic device in a bluetooth communication manner can be used to determine whether the device connected with the electronic device in a bluetooth communication manner is an audio playing device.
As one approach, in an android operating system based electronic device, the type of device currently connected through bluetooth may be determined by a return value obtained based on instantiating a bluetooth class. If the returned value is AUDIO _ VIDEO _ CAMCORDER, the image acquisition equipment is characterized; if the returned value is AUDIO _ VIDEO _ CAR _ AUDIO, the vehicle-mounted equipment is characterized; if the returned value is AUDIO _ VIDEO _ HIFI _ AUDIO, the AUDIO or VIDEO playing device is characterized as an AUDIO playing device or a VIDEO playing device, such as a bluetooth headset; if the returned value is AUDIO _ VIDEO _ MICROPHONE, it is characterized as a MICROPHONE.
Therefore, the condition that the electronic equipment is in Bluetooth communication connection with the audio playing equipment can be detected. In the embodiment of the application, when the Bluetooth communication connection between the electronic device and the audio playing device is detected, the transmission delay time of the electronic device for transmitting the audio data to the audio playing device can be obtained. The transmission delay time of the audio data may be obtained by real-time calculation, or the transmission delay time of the audio data may be stored in the electronic device, and a specific manner of obtaining the transmission delay time of the audio data transmitted to the audio playing device is not limited in the embodiment of the present application.
Step S130: and delaying the dynamic picture by the transmission delay time for displaying.
In the embodiment of the application, after the transmission delay time for the electronic device to transmit the audio data to the audio playing device through bluetooth communication is obtained, the electronic device can be controlled to display the dynamic picture according to the transmission delay.
Specifically, the electronic device may be controlled to display the dynamic picture according to the transmission delay time, and the dynamic picture may be displayed with the transmission delay time delayed. For example, when the transmission delay time is 20 milliseconds, each frame of moving image of the moving picture is displayed with a delay of 20 milliseconds. Therefore, when the dynamic frame images are displayed, the time for the electronic equipment to start transmitting the audio data corresponding to the dynamic frame images is later than the time for the electronic equipment to start transmitting the audio data, when each dynamic frame image is displayed, the corresponding audio data is received and played by the audio playing equipment, and the effect of synchronizing the playing of the audio data and the displayed images is achieved.
Of course, in this embodiment of the application, the dynamic image may start to be displayed in a delayed manner when the electronic device starts to display the dynamic image, that is, after the audio data corresponding to the first frame of dynamic frame image of the dynamic image is transmitted to the audio playing device, the first frame of dynamic frame image starts to be displayed, so that the display time of each subsequent frame of dynamic frame image is later than the time when the audio data starts to be transmitted, and when each frame of dynamic frame image is displayed, the audio playing device correspondingly receives the dynamic frame image displayed at this time along with the corresponding audio data.
According to the display control method provided by the embodiment of the application, when the electronic equipment displays the dynamic picture, the connection state between the electronic equipment and other equipment is detected, when the audio playing equipment is connected with the electronic equipment through the Bluetooth, the transmission delay time from the transmission of the audio data to the audio playing equipment by the electronic equipment is acquired, and finally the dynamic picture is displayed after the transmission delay time is delayed, so that the picture displayed by the electronic equipment is synchronous with the audio data played by the audio playing equipment, and the user experience effect is improved.
In an embodiment, please refer to fig. 2, and fig. 2 is a schematic flowchart illustrating a display control method according to an embodiment of the present disclosure. As will be described in detail with respect to the flow shown in fig. 2, the display control method may specifically include the following steps:
step S210: when the electronic equipment displays the dynamic picture, detecting the connection state between the electronic equipment and other equipment.
When the electronic device displays the dynamic picture, the displayed dynamic picture may have corresponding audio data, and the displayed dynamic picture may also have no corresponding audio data. Therefore, when the electronic device displays the dynamic image, the audio data corresponding to the dynamic image may or may not be output at the same time.
Therefore, in the embodiment of the application, when the electronic device displays the dynamic picture, whether the audio output exists in the application program corresponding to the dynamic picture can be detected. It can be understood that, when the electronic device displays a dynamic picture, an application program corresponding to the dynamic picture does not have audio output, and the situation that the picture display and the sound playing are not synchronous does not need to be considered; when the electronic device displays a dynamic image, an application program corresponding to the dynamic image has audio output, and therefore, the situation that the image display and the sound playing are not synchronous needs to be considered.
Therefore, when the application program corresponding to the dynamic picture is detected to have the output of the audio data, the connection state between the electronic equipment and other equipment can be detected so as to determine whether the electronic equipment transmits the audio data to the audio playing equipment for playing by using the Bluetooth.
Step S220: and when the audio playing device is connected with the electronic device through the Bluetooth, acquiring the transmission delay time of the audio playing device from the electronic device to the audio data.
When the Bluetooth communication connection between the electronic equipment and the audio playing equipment is detected, the transmission delay time of the audio data transmitted by the electronic equipment to the audio playing equipment can be acquired.
As an embodiment, please refer to fig. 3, the obtaining of the transmission delay time for the electronic device to transmit the audio data to the audio playing device may include:
step S221: and acquiring data transmission delay time corresponding to a Bluetooth codec used by the electronic equipment for transmitting the audio data to the audio playing equipment.
It can be understood that, in the process of transmitting audio data to an audio playing device through bluetooth, the audio data is decoded and encoded by a bluetooth codec and then sent to the audio playing device, and the bluetooth codec takes some time to process the audio data, which results in delay brought to audio data transmission by the bluetooth codec, and the delay is also a main delay of audio data transmission, so that the transmission delay of audio data can be determined according to the data transmission delay time brought by the codec.
In the embodiment of the present application, the data transmission delay times corresponding to different bluetooth codecs are different, that is, the audio data transmission delays caused by different bluetooth codecs are different. For example, commonly used codecs such as the ldac codec, the aptx-hd codec, the sbc codec, and the aac codec may have different data transmission delay times.
In this embodiment, a corresponding relationship between the bluetooth codec and the data transmission delay time may be stored, and the data transmission delay time of the bluetooth codec may be obtained through the corresponding relationship. Firstly, the bluetooth codec used by the electronic device in transmitting audio data can be determined, and then the data transmission delay time corresponding to the bluetooth codec used can be found out according to the corresponding relationship.
Step S222: and taking the data transmission delay time corresponding to the Bluetooth codec as the transmission delay of the audio data transmitted by the electronic equipment to the audio playing equipment.
After the data transmission delay time corresponding to the bluetooth codec used by the electronic device to transmit the audio data to the audio playing device is obtained, the transmission delay of the electronic device to transmit the audio data to the audio playing device can be determined, that is, the transmission delay of the electronic device to transmit the audio data to the audio playing device is the data transmission delay time.
As another embodiment, obtaining the transmission delay of the electronic device for transmitting the audio data to the audio playing device may include:
the method comprises the steps of obtaining the transmission time of a response signal between the electronic equipment and the audio playing equipment, and taking the transmission time as the transmission delay time of the audio data transmitted to the audio playing equipment by the electronic equipment, wherein the response signal is a signal returned to the electronic equipment by the audio playing equipment according to the received data.
It can be understood that, when the electronic device performs bluetooth communication with the audio playing device, the electronic device may receive a response signal returned by the audio playing device after sending data to the audio playing device each time. Therefore, the value obtained by dividing the time difference from the time of sending the data to the time of receiving the response signal by 2 can be used as the transmission time of the response signal, and the transmission time of the response signal between the electronic equipment and the audio playing equipment can be used as the transmission delay time of the electronic equipment for transmitting the audio data to the audio playing equipment.
Of course, a specific manner of obtaining the transmission delay time for the electronic device to transmit the audio data to the audio playing device is not limited in the embodiment of the present application, and may also be other manners, for example, the transmission delay of the audio data may be obtained according to interference of the environment where the electronic device is located on bluetooth communication, where different data retransmission rates and transmission rates may correspond to different data transmission delay times according to the retransmission rate, the transmission rate, and the like of the data, so that the transmission delay time of the audio data may be determined according to the retransmission rate and the transmission rate.
Step S230: and acquiring the application type of the application program corresponding to the dynamic picture currently displayed by the electronic equipment.
After the transmission delay of the electronic device for transmitting the audio data to the audio playing device is obtained, the dynamic picture can be displayed in a delayed manner according to the transmission delay time. In the embodiment of the present application, the dynamic picture may be displayed in a delayed manner according to the type of the application program corresponding to the currently displayed dynamic picture and the transmission delay time.
First, the running information of the application program corresponding to the currently displayed dynamic picture may be acquired, and the running information of the application program may include: the application program is in foreground or in background, the functional components called by the application program, the type of the application program, the data output by the application program and the like. It is to be understood that the application supports at least dynamic picture data and audio data, i.e. the application has at least a dynamic picture output and an audio output. For example, the application may include a video playing type application, a game type application, and the like.
And then obtaining the type of the application program in the operation information of the application program, wherein when the type of the application program is determined, all the application programs can be classified in the electronic equipment in advance, the classified application programs are stored in different types correspondingly, and when the application type of the application program is determined, the application program is matched with the stored application programs one by one so as to obtain the type of the application program.
Step S240: and delaying the dynamic picture for the transmission delay time to display based on the application type.
In the embodiment of the present application, after obtaining the application program corresponding to the displayed dynamic picture, the dynamic picture may be displayed in a delayed manner based on the application type and the transmission delay time. The time for determining the delayed display of the dynamic picture based on the transmission delay time may be different according to different application types.
It can be understood that for different application types of application programs, the real-time requirement for displaying the screen is different, and if the time for delaying the display of the screen is too long, the user experience is affected. It is therefore possible to display the time in which the dynamic picture delay is less than or equal to the transmission delay time, depending on the type of application.
In the embodiment of the present application, please refer to fig. 4, step S240 may include:
step S241: and when the application type is a video type, delaying the dynamic picture by the transmission delay time for displaying.
It can be understood that, when the application type of the application program corresponding to the dynamic picture is a video type, a picture currently displayed by the electronic device is a video picture, and the video picture does not need to be completely synchronized with the current time, so that the dynamic picture can be displayed by delaying the transmission delay time. For example, if the transmission delay of audio data is 5 milliseconds, the moving picture is displayed with a delay of 5 milliseconds. Therefore, the dynamic picture played by the electronic equipment is completely synchronous with the audio data played by the audio playing equipment, and the watching experience of a user is improved.
Step S242: and when the application type is a game type, the dynamic picture is displayed by delaying the set time which is less than the transmission delay time.
It can be understood that, when the application type of the application program corresponding to the dynamic screen is a game type, the screen currently displayed by the electronic device is a dynamic game screen, and the game screen usually needs to be displayed in real time to ensure the real-time performance of the game, so that the dynamic screen can be displayed with a delay set time, the set time is less than the transmission delay time of the audio data, that is, the dynamic screen is displayed with a delay less than the transmission delay time, and the real-time performance of the screen display and the synchronization between the screen and the sound are integrated to display. For example, if the transmission delay of the audio data is 2 milliseconds, the dynamic picture can be displayed with a delay of 1 millisecond, so that the game picture can be approximately synchronized with the audio data played by the audio playing device while the game picture can be approximately kept in real-time, and the game experience of the user is improved.
In the embodiment of the present application, in the determining of the transmission delay time of the audio data, if the transmission delay time is determined using the data transmission time of the bluetooth codec, the display control method may further include:
and selecting a set number of target codecs from all Bluetooth codecs of the electronic equipment as the Bluetooth codecs used by the electronic equipment for transmitting the audio data to the audio playing equipment, wherein the data transmission delay time corresponding to the target codecs is shorter than the data transmission delay time corresponding to other Bluetooth codecs.
It is understood that a plurality of bluetooth codecs may be included in the electronic device. When the electronic device includes a plurality of bluetooth codecs, the required number of the codecs from the plurality of bluetooth codecs of the electronic device can be selected as the bluetooth codecs required by the electronic device to transmit the audio data to the audio playing device according to the data transmission delay time corresponding to the bluetooth codecs. And, the data transmission time of the selected codec with the required number should be shorter than the data transmission delay time corresponding to other bluetooth codecs, and the other codecs are divided by the plurality of bluetooth codecs. Therefore, the transmission delay time of the audio data transmitted by the electronic equipment to the audio playing equipment can be reduced. In addition, after determining the bluetooth codec used by the electronic device to transmit the audio data, the display control method needs to determine the transmission delay of the audio data and then display the dynamic picture delay.
According to the display control method provided by the embodiment of the application, when the electronic equipment displays the dynamic picture, whether the audio output exists in the application program corresponding to the dynamic picture is judged, when the audio output exists, the connection state between the electronic equipment and other equipment is detected, then when the audio playing equipment is connected with the electronic equipment through Bluetooth, the transmission delay time of the audio data transmitted to the audio playing equipment is acquired, and various implementation modes of the transmission delay of the audio data are provided. After the transmission delay of the audio data is obtained, when the dynamic picture is delayed and displayed, the type of the application program is considered, and the picture delay display time is determined according to the type of the application program, so that the picture displayed by the electronic equipment and the audio data played by the audio playing equipment are ensured to be synchronous, and the user experience when different types of application programs are used is ensured.
In an embodiment, please refer to fig. 5, and fig. 5 is a flowchart illustrating a display control method according to an embodiment of the present application. As will be described in detail with respect to the flow shown in fig. 5, the display control method may specifically include the following steps:
step S310: when the electronic equipment displays the dynamic picture, detecting the connection state between the electronic equipment and other equipment.
Step S320: and when the audio playing device is connected with the electronic device through the Bluetooth, acquiring the transmission delay time of the audio playing device from the electronic device to the audio data.
In the embodiment of the present application, reference may be made to the description in the above embodiment in step S310 to step S320, which is not repeated herein.
Step S330: and judging whether the content of the dynamic picture is from a network.
After the transmission delay time for the electronic device to transmit the audio data to the audio playing device is obtained, the dynamic picture can be displayed in a delayed manner according to the transmission delay time. In the embodiment of the present application, the dynamic picture can be displayed in a delayed manner according to the source of the content of the dynamic picture.
It is understood that the content of the dynamic picture displayed by the electronic device may originate from a network or from data stored locally in the electronic device. When the content of the dynamic picture comes from the network, a network delay may occur, resulting in a delay in acquiring the content of the picture. Therefore, it is possible to determine whether or not the content of the dynamic picture originates from the network, so as to determine the time at which the dynamic picture is delayed from being displayed when the content of the dynamic picture originates from the network.
Step S340: and if the content is sourced from the network, acquiring the current network delay time of the electronic equipment.
When the content of the dynamic picture is determined to be from the network in step S330, the network information of the electronic device may be obtained, and the current network delay time may be determined.
When the electronic device is an android operating system-based device, the NetworkInfo object corresponding to the ConnectivityManager object is acquired after the ConnectivityManager object is acquired, and then information about network connection is taken out of the NetworkInfo object. The ConnectivityManager object is used for viewing network states and managing network connection related operations, and the NetworkInfo object contains all information of network connections. From all the information obtained for the network connection, the current network delay time can be determined.
Step S350: and determining the display delay time of the dynamic picture based on the transmission delay time and the current network delay time, and delaying the audio data of the dynamic picture for transmitting by the current network delay time while delaying the dynamic picture for displaying by the display delay time.
After obtaining the current network delay time of the electronic device, the display delay time of the dynamic picture may be determined based on the transmission delay time of the audio data and the current network delay time. The current network delay time may be added to the transmission delay time of the audio data to obtain the display delay time of the dynamic picture. And after obtaining the display delay time, delaying the dynamic picture by the display delay time for displaying, and in addition, delaying the audio data corresponding to the dynamic picture by the current network delay and transmitting the audio data to the audio playing equipment. . For example, when the obtained current network delay time is 5 milliseconds and the transmission delay time of the audio data is 2 milliseconds, the display delay time for the dynamic picture to be displayed in a delayed manner is 7 milliseconds, and when the dynamic picture is displayed, the dynamic picture is displayed in a delayed manner by 7 milliseconds, and the audio data corresponding to the dynamic picture is transmitted to the audio playing device in a delayed manner by 5 milliseconds.
It can be understood that the dynamic picture is displayed by delaying the time of the current network delay time and the transmission delay time of the audio data, so that the displayed dynamic picture is the data which is cached by the electronic device, and the picture displayed by the electronic device is not jammed due to the network delay.
