Description

Play control method and device in audio and video play system

technical field

Embodiments of the present invention relate to the field of communication technologies, and in particular, to a playback control method and device in an audio and video playback system.

Background technique

The audio and video playback system is composed of multiple playback devices. The playback devices generally integrate network communication functions. Multiple playback devices in different areas can be connected to the network to form an audio and video playback system. Usually, multiple playback devices in the audio and video playback system will form a private network wirelessly, for example, a wireless mesh (mesh) network technology can be used to form a private network, and each playback device can exchange information and data. Smartphones and other audio source devices can be used as control terminals to connect with the audio and video playback system through wireless communication technology to control the audio and video playback system and transmit audio and video data.

As shown in Figures 1A and 1B, there are two common music playback systems in the prior art, including playback devices and routers. Wherein, the playback device 11 shown in FIG. 1A establishes a wired connection with the router 12, the playback device 11 shown in FIG. 1B establishes a wireless connection with the router 12, and the router establishes a connection with the Internet or a local area network.

Wherein, the playback device 11 connected to the router 12 is defined as the master playback device of the music playback system, and other playback devices (such as the playback device 13, the playback device 14 and the playback device 15) are defined as the slave playback devices. After the intelligent terminal 16 installed with special application software is connected to the router 12, it can access and control the playback equipment in the private network of the music playback system. For example, the user can select the song he wants to play on the smart terminal 16, and the smart terminal 16 sends the song data of this song to the main playback device 11. When playing, the user can select the playback device as the main playback device, and only control the Play on the main playback device 11, also can select the playback device to be all playback devices, control the main playback device 11 with song data, send to the slave playback device (player device 13, playback device 14 and playback device 15) in the private network, make 4 playback devices play the same song synchronously.

In the audio and video playback system, the playback devices in each playback group are usually used to play different types of audio and video files. For example, the playback devices in the children's room are often used to play nursery rhymes, and the playback devices in the living room usually form a multi-channel playback The group is used to play movie music, and the playback equipment in the study is usually used to play some soothing light music, etc. In the playback control method of audio and video playback devices in the prior art, when the user controls the playback device to play a song through the audio source device, the user needs to manually select the playback device or playback device group to play the song before controlling the playback device or playback device. The device group plays songs, the operation is cumbersome, the intelligence is low, and the user experience is not good.
