Embodiment 1

[0051] see figure 1 , shows the method for playing media data provided by the embodiment of the present invention.

[0052] The playback method of the media data is applied in the playback device, and specifically includes the following steps:

[0053] In step S102, media data is acquired.

[0054] Preferably, before step S102, step S101 is further included, receiving the acquisition path of the media data sent by the master playback device. In this way, each slave playback device acquires the media data according to the acquisition path.

[0055]In this embodiment, the master playback device sends an acquisition path of media data to each slave playback device, and each slave playback device acquires corresponding media data according to the acquisition path. Since each secondary playback device acquires media data from the same path, it is ensured that the media data obtained by each secondary playback device is consistent, laying a foundation for synchronization.

[005...

Embodiment 2

[0089] see figure 2 , shows the method for playing media data provided by the embodiment of the present invention.

[0090] Taking the mobile phone as the main playback device and the secondary playback device as a smart speaker, describe in detail how the mobile phone controls multiple smart speakers to play the same song synchronously:

[0091] In step S201, each smart speaker receives the acquisition path of the song "The Most Beautiful Light" sent by the mobile phone http: / / bd.kuwo.cn / yinyue / 3280107? from=dq360.

[0092] In step S202, each smart speaker acquires the data of the song "The Most Beautiful Light" by itself according to the acquisition path to the local end.

[0093] In step S203, each smart speaker decodes the song data using the same decoding rule, and packs the decoded song data using the same packing rule to obtain 5 data packets; then, using the same marking rule, sequentially Mark the serial numbers on the five data packets to obtain data packet 1, da...

Embodiment 3

[0102] see image 3 , shows the method for playing media data provided by the embodiment of the present invention.

[0103] The playback method of the media data is applied in the main playback device, and specifically includes the following steps:

[0104] In step S302, the identifier of the media data package to be played and its playing time are acquired.

[0105] Preferably, before step S302, step S301 is also included, sending the acquisition path of the media data to each slave playback device, so that the slave playback device acquires the media data according to the acquisition path, and processes the media data, Obtain the media data packet and its corresponding identifier.

[0106] Wherein, the master playback device sends the acquisition path of the media data to each slave playback device, and each slave playback device acquires the corresponding media data according to the acquisition path. Since each secondary playback device acquires media data from the same ...

Abstract

The invention provides a media data playing method, device and system. Slave playing equipment acquires media data and processes the media data so as to obtain a media data packet and the corresponding identifier; master playing equipment acquires the identifier of a media data packet to be played and playing time thereof; a playing command is generated according to the identifier of the media data packet to be played and playing time thereof; the playing command is transmitted to each set of slave playing equipment; and the slave playing equipment plays the media data packet corresponding to the identifier according to the playing command when playing time arrives. Therefore, occupation of network bandwidth can be effectively reduced, and more slave playing equipment is allowed to perform synchronous playing under the same wired bandwidth. Besides, each set of slave playing equipment only requires to guarantee the integrity of the acquired media data so that the playing stability of the scheme is better.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for playing media data. Background technique [0002] In the prior art, a smart multimedia system, as a kind of smart home, often consists of multiple smart multimedia devices. These smart multimedia devices can be synchronously controlled through the network to perform a certain operation at the same time, such as synchronously playing a certain song. Considering the media data transmission of each intelligent multimedia device (such as a playback device) as a media stream, the synchronous playback between multiple intelligent multimedia devices can be understood as inter-stream synchronization. [0003] The existing main playback device controls the output of media data from the playback device as follows: the main playback device obtains the media data to be played, and decodes it, and then repackages the decoded media data into a dat...
