[0033] see figure 1 , figure 1 It is a schematic flowchart of a multimedia synchronous playing method provided by the first embodiment of the present invention. The methods include:

[0034] Step S101, acquiring an actual data transmission rate corresponding to a transmission channel between a master device and a slave device.

[0035] It can be understood that the method described in this embodiment mainly describes a playback group composed of multiple playback devices in a multimedia synchronous playback system. Wherein, in the playback group, multiple playback devices are connected through wired transmission or wireless transmission to form a private network environment. Wherein, the wireless transmission mode may be infrared, bluetooth, WiFi (Wireless Fidelity, wireless local area network), hotspot network, and the like. The private network environment can be connected to one or more routers, and then connected to the Internet through the routers, so that one or more ...

[0050] Please also refer to figure 2 , figure 2 It is a schematic flowchart of a multimedia synchronous playing method provided by the second embodiment of the present invention. The methods include:

[0051] Step S201, acquiring the actual data transmission rate corresponding to the transmission channel between the master device and the slave device.

[0052] It can be understood that the master device establishes a transmission channel with each slave device based on a communication network protocol, and the transmission channel is used for the master device to transmit media data to the slave devices. In the process of media data transmission, the leading device can package the media data according to a certain unit, for example, package the media data according to the data size and media frame contained in a unit time.

[0053] When starting to play, the master control device sends media data to all slave devices for synchronous playback. It can be understood that mul...

Abstract

The invention discloses a multimedia synchronous playing method, device and system and a terminal. The method comprises the following steps: acquiring an actual data transmission rate corresponding to a transmission channel between main control equipment and slave equipment and an average data transmission rate corresponding to the transmission channel; and adjusting a data transmission rate of the transmission channel according to the actual data transmission rate and the average data transmission rate in order to realize synchronous playing of the main control equipment and the slave equipment. In a synchronizing process, transmission delay between the main control equipment and the slave equipment is controlled by control of data transmission rates with the slave equipment through the main control equipment to realize synchronous playing regulation and control of the slave equipment, and the main control equipment does not need to perform complicated interaction with the slave equipment, so that the interaction stress on the main control equipment is relieved.

Description

technical field [0001] The present invention relates to the technical field of multimedia playback, in particular to a multimedia synchronous playback method, device, terminal and system. Background technique [0002] Multiple playback devices (such as mobile phones, computers, speakers, various players, etc.) are connected through wired or wireless network technology to form a multimedia synchronous playback system, which plays the same audio, video or picture synchronously, which has been widely used. Taking the multimedia synchronous playback system as an example, how to realize the synchronous playback of multiple playback devices, so that the sound or picture delay between multiple devices is as small as possible, so as to ensure the user's sense of hearing or visual consistency, this is multi-device synchronization Key technologies for playback. [0003] For example, among multiple playback devices that realize synchronous playback, when the master device and other sl...
