Embodiments of the present invention provide a playback control method, device, and terminal, which will be described in detail below.

Example 1

This embodiment will be described from the perspective of a playback control apparatus. The apparatus may be specifically integrated in a terminal, and the terminal may be a device such as a smart phone or a tablet computer.

A playback control method, comprising: acquiring audio data; splitting the audio data into a plurality of data packets, the data packets including a data packet identifier; sending the data packet to a playback device; sending a playback command to the playback device, the The play command is associated with the data packet identification to instruct to play the data packet corresponding to the data packet identification.

As shown in Figure 1, the playback control method, the specific process may include:

S101, acquire audio data.

In a specific application, the playback control device can acquire audio data through various ways. For example, the playback control device can obtain audio data from a server through a wired network, can obtain audio data from other terminals through a wireless network such as Bluetooth, and can also obtain audio data from a storage medium such as an optical disc. The audio data includes, but is not limited to, audio data in formats such as CD, WAV, MP3 (Moving Picture Experts Group Audio Layer III), and WMA (Windows Media Audio).

S102: Split the audio data into multiple data packets, where the data packets include a data packet identifier.

Specifically, after acquiring the audio data, the playback control apparatus splits the audio data into multiple data packets. Preferably, the audio data can be split into multiple data packets of equal length. For example, split the audio data into multiple packets with an audio length of 100ms. When splitting into multiple packets, the packet ID can be set in each packet. The data packet identifier is a unique identifier that distinguishes each data packet from other data packets, and can be used to mark the position of the data packet in the audio data. For example, the data packet identification may be the sequence number of the data packet. Set the packet ID to 1 in the first split data packet, set the packet ID to 2 in the second split packet, and so on.

S103, send the data packet to the playback device.

Specifically, after splitting out multiple data packets, the playback control apparatus sends the multiple data packets to the playback device in sequence. In practical applications, the transmission may be performed in a wired manner, or may be transmitted in a wireless manner such as WiFi (Wireless Fidelity, wireless fidelity) or Bluetooth.

Please refer to FIG. 2 . FIG. 2 is a schematic diagram showing the composition of a playback system in this embodiment. The playback system is composed of a server 105 , a playback control device 106 and a plurality of playback devices 107 . Server 105 may be a server located on a network. The playback control device 106 may be an electronic device integrated in the terminal, or may be a playback device with a data processing function. The playback device 107 may be a device with an audio playback function, such as a speaker, a music player, and the like. The playback control device 106 performs data communication with the server 105 through the Internet, so that the playback control device 106 can acquire audio data from the server 105 . At the same time, the playback control apparatus 106 performs data communication with the plurality of playback devices 107 through wireless communication (eg WiFi), so that the playback control apparatus 106 can send data packets to the playback devices 107 .

S104: Send a play command to the playing device, where the play command is associated with the data packet identifier to instruct to play the data packet corresponding to the data packet identifier.

Specifically, the playback control apparatus may send the playback command to the playback device when receiving the playback command from the user. The playback command received by the playback control device may be a playback command input by the user through a key or a screen, or may be a timing playback command set by the user. The playback command sent by the playback control apparatus to the playback device may be associated with the data packet identifier. Association means that there is a corresponding relationship between the play command and the data packet identifier, that is, it can be determined which data packet or data packets corresponding to which data packet identifiers are played can be determined according to the play command. For example, the play command may include the sequence number of the data packet to instruct the playback device to start playing the data packet corresponding to the sequence number after receiving the play command. The play command may also include multiple data packet sequence numbers. For example, the play command includes data packet sequence numbers 8, 9, and 10 to instruct to play data packet 8, data packet 9, and data packet 10 in sequence.

In some embodiments, after sending the playback command to the playback device, the playback control method may further include the following steps:

Get the delay time;

A delay command is sent to the playback device, where the delay command indicates that the playback command is received and the data packet corresponding to the data packet identifier is played after the delay time.

Specifically, the delay duration may be a time value preset by the user and stored in the memory of the playback control device. The playback control device acquires the delay time length from the memory, and then sends a delay command to the playback device. The delay command instructs the playback device to play the data packet corresponding to the data packet identifier after the delay time has elapsed after receiving the playback command. For example, the identifier of the data packet associated with the play command is the data packet sequence number 8, and the delay time is 200ms. Then, after receiving the play command, the playback device starts to play the data packet 8 after 200ms.

In some embodiments, the delay duration may be obtained by calculation. Obtaining the delay time may specifically include the following steps:

Get the preset duration;

Get the network delay with the playback device;

The delay duration is calculated according to the preset duration and the network delay.

Specifically, the preset duration may be a time value preset by the user and stored in the memory of the playback control device. The playback control device acquires the preset duration by calling the time value in the memory. Due to the influence of the communication distance between the playback control device and the playback device, or the influence of other factors such as electromagnetic interference, there is usually a certain network delay between the playback control device and the playback device. The playback control apparatus can obtain the network delay with the playback device by monitoring the network communication state. After the preset duration and the network delay are obtained, the delay duration is calculated according to the preset duration and the network delay.

In some embodiments, calculating the delay duration according to the preset duration and the network delay may specifically include the following steps:

calculating the difference between the preset duration and the network delay;

Use this difference as the delay time.

Specifically, the difference between the preset duration and the network delay may be calculated, and the difference may be used as the delay duration. For example, if the preset duration is 500ms and the network delay is 100ms, it can be calculated that the difference between the preset duration and the network delay is 400ms. Then, take 400ms as the delay time.

In some embodiments, the playback device may include multiple playback devices, and acquiring the preset duration may specifically include the following steps:

Get multiple network delays with the multiple playback devices;

Set the largest of the network delays to the preset duration.

Specifically, the playback devices in the playback system may include multiple playback devices. The playback control apparatus can monitor the network communication states with the multiple playback devices respectively to obtain multiple network delays with the multiple playback devices. Then, the multiple network delays are compared to determine the one with the largest network delay, and the maximum network delay is set as a preset duration. For example, the playback device includes 3 units. If the network delays between the playback control device and the three playback devices are respectively 500ms, 400ms, and 300ms, it can be determined that the largest one of the three network delays is 500ms. Then, set the preset duration to 500ms.

After the delay command is sent to the playback device, the influence caused by the network delay between the playback control device and the playback device can be reduced, thereby improving the synchronization of playback among multiple playback devices.

During specific implementation, the present invention is not limited by the execution order of the described steps, and certain steps can also be performed in other sequences or simultaneously under the condition of no conflict.

As can be seen from the above, the playback control method provided by the embodiment of the present invention adopts acquiring audio data; splitting the audio data into a plurality of data packets, the data packets including a data packet identifier; sending the data packet to a playback device; The play device sends a play command, where the play command is associated with the data packet identifier to instruct to play the data packet corresponding to the data packet identifier. The scheme sends a playback command associated with the data packet identifier to the playback device, so that after receiving the playback command, multiple playback devices can start playing the data packet corresponding to the data packet ID at the same time, without the need for the clock system of each playback device. Calibration can achieve a good synchronous playback effect among multiple playback devices, and compared with the prior art, the synchronization between multiple playback devices can be improved.

Embodiment 2

According to the playback control method described in the first embodiment, the following examples will be used for further detailed description.

In this embodiment, the playback control device is specifically integrated in the smart phone, and the playback control method of the playback control device in the smart phone is taken as an example for detailed description.

As shown in Figure 3, the specific process of the playback control method can be as follows:

S201, the smartphone acquires audio data.

In a specific application, a smartphone can acquire audio data in various ways. For example, a smartphone can obtain audio data from a server through a wired network, and can also obtain audio data from terminals such as other smartphones and personal computers through a wireless network such as Bluetooth.

S202, the smartphone splits the audio data into multiple data packets, where the data packets include a data packet identifier.

Specifically, after acquiring the audio data, the smartphone splits the audio data into multiple data packets. Preferably, the audio data can be split into multiple data packets of equal length. For example, split the audio data into multiple packets with an audio length of 100ms. When splitting into multiple packets, the packet ID can be set in each packet. The data packet identification may be a sequence number of the data packet. For example, set the packet ID to 1 in the first split data packet, set the packet ID to 2 in the second split data packet, and so on.

S203, the smart phone sends the data packet to the playback device.

Specifically, after the smartphone splits multiple data packets, the multiple data packets are sequentially sent to multiple playback devices. In practical applications, the transmission may be performed in a wired manner, or may be transmitted in a wireless manner such as WiFi (Wireless Fidelity, wireless fidelity) or Bluetooth. The multiple playback devices may be devices with audio playback functions, such as speakers, music players, and the like.

S204, the smart phone sends a play command to the playing device, where the play command is associated with the data packet identifier to instruct to play the data packet corresponding to the data packet identifier.

Specifically, the smart phone may send a play command to the plurality of play devices when receiving a play command from the user. The play command received by the smart phone from the user may be a play command input by the user through a key or a screen, or a timed play command set by the user. The playback command sent by the smartphone to the playback device may be associated with the data packet identification. Association means that there is a corresponding relationship between the play command and the data packet identifier, that is, it can be determined which data packet or data packets corresponding to which data packet identifiers are played can be determined according to the play command. For example, the play command may include the sequence number of the data packet to instruct the playback device to start playing the data packet corresponding to the sequence number after receiving the play command. The play command may also include multiple data packet sequence numbers. For example, the play command includes data packet sequence numbers 8, 9, and 10 to instruct to play data packet 8, data packet 9, and data packet 10 in sequence.

S205, the smartphone acquires multiple network delays between multiple playback devices.

Specifically, due to the influence of the communication distance between the smart phone and the playback device, or the influence of other factors such as electromagnetic interference, there is usually a certain network delay between the smart phone and the playback device. The smart phone can monitor the network communication status with multiple playback devices in real time to obtain multiple network delays with the multiple playback devices.

S206, the smartphone sets the largest one of the multiple network delays as a preset duration.

Specifically, after acquiring multiple network delays with multiple playback devices, the smartphone compares the multiple network delays, determines the one with the largest network delay, and then sets the maximum network delay as a preset duration. For example, the playback device includes 3 units. If the network delays obtained by the smartphone and the three playback devices are 500ms, 400ms, and 300ms, respectively, it can be determined that the largest one of the three network delays is 500ms. Then, set the preset duration to 500ms.

S207, the smartphone acquires the network delay between the playback device and the smartphone.

Specifically, the smartphone can monitor the network communication status with each playback device in real time to obtain the network delay with each playback device. Since the network delay changes dynamically, the multiple network delays obtained in S205 are used to set the preset duration. At this time, the network delay between each playback device and each playback device is obtained again, and the required amount of each playback device can be calculated more accurately. delay time.

When the requirement for synchronization between multiple playback devices is not high, step S207 can also be omitted, and the multiple network delays obtained in step S205 between the multiple playback devices are used as the distance between the smartphone and each playback device. network latency.

S208, the smartphone calculates the difference between the preset duration and the network delay.

Specifically, after acquiring the network delay with each playback device, the smartphone calculates the difference between the preset duration and each acquired network delay. For example, the playback device includes 3 units. The network delays obtained by the smartphone and the three playback devices are 450ms, 350ms, and 300ms, respectively. Then, the difference between the preset duration and the network delays of the three playback devices can be calculated to be 50ms, 150ms, and 200ms, respectively.

S209, the smartphone uses the difference as the delay time.

Specifically, after calculating the multiple differences between the preset duration and the acquired network delays, the smartphone sets the multiple differences as the delay durations required by the multiple playback devices, respectively. For example, set the delay duration of a playback device with a network delay of 450ms to 50ms, set the delay duration of a playback device with a network delay of 350ms to 150ms, and set the delay duration of a playback device with a network delay of 300ms to 200ms.

S210, the smart phone sends a delay command to the multiple playback devices, where the delay command indicates that the playback command is received and the data packet corresponding to the data packet identifier is played after the delay time.

Specifically, after setting the delay time of each playback device, the smartphone sends a delay command to each playback device respectively, to instruct the playback device to receive the playback command, and then start playing and the playback after the delay time. The data packet associated with the command identifies the corresponding data packet. For example, a delay command sent to a playback device with a network delay of 450ms instructs the playback device to receive the playback command and starts to play the corresponding data packet after 50ms; a delay command sent to a playback device with a network delay of 350ms indicates the playback device The playback device receives the playback command and starts playing the corresponding data packet after 150ms; the delay command sent to the playback device with a network delay of 300ms instructs the playback device to receive the playback command and start playing the corresponding data packet after 200ms . For a playback device with a larger network delay, the delay time in the delay command sent by the smartphone to the playback device is smaller; for a playback device with a smaller network delay, the delay time in the delay command sent by the smartphone to the playback device is shorter. The longer the delay time is. Therefore, when multiple playback devices receive a playback command, the multiple playback devices can be controlled to actually play the same data packet at the same time.

During specific implementation, the present invention is not limited by the execution order of the described steps, and certain steps can also be performed in other sequences or simultaneously under the condition of no conflict.

As can be seen from the above, the playback control method provided by the embodiment of the present invention adopts acquiring audio data; splitting the audio data into a plurality of data packets, the data packets including a data packet identifier; sending the data packet to a playback device; The playback device sends a playback command, and the playback command is associated with the data packet identification to indicate that the data packet corresponding to the data packet identification is played; obtain multiple network delays with multiple playback devices; calculate and set the multiple playback devices The delay time of the device; send a delay command to the multiple playback devices, the delay command indicates that the playback command is received and the data packet corresponding to the data packet identifier is played after the delay time. In this scheme, after sending a playback command to multiple playback devices, it immediately sends a delay command to the multiple playback devices to instruct each playback device to receive the playback command and play the corresponding data packet after the delay time. Due to the influence of the network delay between the smartphone and the playback device, multiple playback devices actually play the same data packet at the same time. Compared with the prior art, the synchronization between the multiple playback devices can be improved.
