Abstract

the invention discloses a method for realizing multi-machine synchronous playing based on a cloud network music player, which is characterized in that only one player is allocated as a host machine in a local area network, other players are slave machines, when the main player is started, the URI address of the cloud end is read from a prestored list, an HTTP client end is opened and is connected with a cloud server through the URI address, after the connection is successful, the HTTP client end actively acquires an audio list, and the appointed downloading of music corresponding to the cloud end of the audio list is selected, when a music data frame is cached, and a certain data frame is reached, the main player opens a multicast function and sends a time-cut synchronization message. And after receiving the time-truncated synchronous message, the slave player immediately processes and waits for receiving the music data frame of the master player, and when the music data frames of the master player and the slave player are equal, the master player sends a playing instruction to enable the slave player to play the music together.

step S111: starting audio decoding;

Step S112: until the decoding is finished;

The slave player realizes the following flow:

step S201, a multicast thread is established;

Step S202, monitoring the multicast port, if data exists, jumping to S203, otherwise, monitoring all the time;

step S203: verifying whether the message is correct, if so, jumping to S204, otherwise, jumping to S202;

step S204: judging whether the message is time-truncated, if so, jumping to S205;

step S205: synchronizing time truncation;

step S206: creating a thread for receiving music data frames;

step S207: caching the music data frame all the time;

Step S208: judging whether the instruction is played, if so, jumping to S209;

step S209: starting audio decoding;

step S210, until the decoding is finished.

compared with the prior art, the invention has the beneficial effects that at least:

The method for realizing multi-machine synchronous playing based on the cloud network music player effectively solves the problem that the music can be played simultaneously in a plurality of areas and independent areas.

Detailed Description

in order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. It should be noted that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by those skilled in the art without any inventive work based on the embodiments of the present invention belong to the protection scope of the present invention.

the invention realizes the synchronous playing of a plurality of players, the invention refers to that only one player is allocated as a host in a local area network, other players are slaves, when the main player is started, the URI address of a cloud is read from a prestored list, an HTTP client is opened and is connected with a cloud server through the URI address, after the connection is successful, the HTTP client actively acquires an audio list and selects the appointed downloading of the audio list to the music corresponding to the cloud, when a music data frame is cached and reaches a certain data frame, the main player opens a multicast function and sends a time interception synchronization message. And after receiving the time-truncated synchronous message, the slave player immediately processes and waits for receiving the music data frame of the master player, and when the music data frames of the master player and the slave player are equal, the master player sends a playing instruction to enable the slave player to play the music together.

The method for realizing multi-zone and independent zone playing in the smart home comprises the following steps: the master and slave players are assigned up to 16 zone numbers 1, 2.. 16, respectively. Multi-region playing: when the master player selects area code 1 to play, the master player can use the multicast port to send the area code 1 to the network in real time, and all the slaves with the area code 1 can play following. And (3) playing in the independent area: the slave player in area code 1 can play independently without being affected by the host playing.
