Embodiment 1

[0038] This embodiment will be described from the perspective of a playback control device. Specifically, the device may be integrated into a terminal, and the terminal may be a device such as a smart phone or a tablet computer.

[0039] A playback control method, comprising: splitting audio data into multiple audio data packets, the audio data packets include a first time stamp; acquiring a clock error of a playback device; modifying the audio data packet in the audio data packet according to the clock error First time stamp to obtain the modified audio data packet; send the modified audio data packet to the playback device.

[0040] Such as figure 1 As shown, the playback control method, the specific process may include:

[0041] S101. Split the audio data into multiple audio data packets, where the audio data packets include a first time stamp.

[0042] In a specific application, the playback control device can call the audio data stored in the memory of the playback cont...

Embodiment 2

[0079] According to the playback control method described in the first embodiment, an example will be given below for further detailed description.

[0080] In this embodiment, the playback control device will be specifically integrated in the smart phone, based on figure 2 The playing system shown is a detailed description of the playing control method of this embodiment.

[0081] Such as figure 2 Shown is a schematic diagram of the composition of a playback system in this embodiment. The playback system consists of a server 211 , a smart phone 212 and multiple playback devices 213 . Server 211 may be a server located on a network. The playback device 213 may be a device with an audio playback function such as a speaker or a music player. The smart phone 212 performs data communication with the server 211 through the Internet, so that the smart phone 212 can obtain audio data from the server 211 . At the same time, the smart phone 212 performs data communication with m...

Embodiment 3

[0113] In order to better implement the above method, an embodiment of the present invention further provides a playback control device, which can be integrated into a terminal, and the terminal can be a device such as a smart phone or a tablet computer.

[0114] Such as Figure 4 As shown, the playback control device 300 may include: a splitting module 301, an acquiring module 302, a modifying module 303, and a sending module 304, which are specifically described as follows:

[0115] The splitting module 301 is configured to split the audio data into multiple audio data packets, where the audio data packets include a first timestamp;

[0116] The obtaining module 302 is used to obtain the clock error of the playback device;

[0117] The modifying module 303 is configured to modify the first timestamp in the audio data packet according to the clock error to obtain a modified audio data packet;

[0118] The sending module 304 is configured to send the modified audio data pack...

Abstract

The embodiment of the invention provides a playing control method and device, a terminal and a playing system. The method comprises the steps of splitting audio data into a plurality of audio data packets, wherein the audio data comprises first time stamps; obtaining clock errors of playing devices; modifying the first time stamps contained in the audio data according to the clock errors, thereby obtaining the modified audio data packets; and sending the modified audio data packets to the playing devices. According to the scheme, the first time stamps contained in the audio data are modified according to the clock errors of the playing devices, the actual time of playing the modified audio data packets by the playing devices is the time corresponding to the first time stamps. When the plurality of playing devices carry out playing at the same time, the time of playing the same audio data packet by the plurality of playing devices is the same. Compared with the prior art, the method, the device, the terminal and the playing system have the advantage that the audio data playing synchronism among the plurality of playing devices can be improved.

Description

technical field [0001] The present invention relates to the technical field of electronic equipment, in particular to a playback control method, device, terminal and playback system. Background technique [0002] With the improvement of living standards, audio-visual equipment plays an important role in people's lives. Currently, it has been widely used to connect multiple music playback devices (such as speakers, players, mobile phones, etc.) and control devices to each other through a wired or wireless network to form a playback system and play the same music synchronously. [0003] In the above playback system, each device has an independent system clock. Each playback device plays music according to its own system clock. However, the system clocks of the various playback devices and control devices are not always synchronized. There may be a slight time difference between each playback device and control device. When multiple playback devices play the same music, the...
