The stereophonic playing instruction can be issued actively by the server side or by the operation of the user. In one intelligent scenario, the service end pushes the matching music track based on the current environment in which the playback device is located, and actively issues the stereo playback instruction. In another intelligent scene, the server side issues the stereo playing instruction according to a man-machine interaction instruction such as an expression instruction, a gesture instruction, a voice instruction and the like of a user. In another smart scenario, the server may receive a user operation instruction sent by an application installed in a control terminal (e.g., a mobile terminal such as a mobile phone or a central control device in a local area network) corresponding to a playback device, and generate the above-mentioned stereo playback instruction based on the user operation instruction. In another intelligent scene, the playing device responds to the trigger operation of the set entity key and sends an operation instruction to the server. And the server generates the stereo playing instruction based on the operation instruction. In addition, in the case that the playing device and the server do not have a direct network connection state, the playing device may be connected to the control terminal through end-to-end communication, and the above operation instruction, man-machine interaction instruction, and the like may be forwarded to the server via the control terminal. In addition, in the case where the playback apparatus has a network connection state with the server, the playback apparatus may transmit the operation instruction and the man-machine interaction instruction described above to the server through a network such as the internet. In addition, the server may be provided with services such as voice recognition, face recognition, etc. The server may also be used to provide storage of digital media assets. The server may be implemented as one or more servers. Each server may act as one or more physical entities. The server may be logically configured as a whole or as an application server and a resource server. The application server may be used to provide application services (such as device management, user management, network management) associated with the playback device, such as voice recognition services, face recognition services, and the like. The resource server may be used to provide storage of digital media resources. The application server and the resource server can access each other. For example, for access to a resource server, the application server may have higher rights than the playback device, so as to ensure copyrights or digital security of the resource server. The resource server may perform user authorization, operation authorization, device authorization, etc. on the playback device via the application server.

The streaming media communication connection may be based on any network connection. For example, the streaming media communication connection may be a connection under a heterogeneous network node. The streaming media communication connection may also be a connection based on a local area network access point (e.g., wireless fidelity, WIFI). The streaming media communication connection may also be a connection based on a mobile communication network (e.g. 3G/4G/5G). The streaming media communication connection may also be any form of end-to-end connection, for example, a Mesh network (i.e., a Many-to-Many network (Many)) based connection, such as a bluetooth Mesh connection. The streaming media communication may be any one of unicast communication, multicast communication and multicast communication. The embodiment of the present invention is not limited thereto.

220: and responding to the stereo playing control instruction, playing the first sound channel, and controlling the second sound channel to be played from the playing device through the streaming media communication connection.

The stereo configuration information and the connection configuration information of the main playback device may be simultaneously issued as the main playback device configuration information. The stereo configuration information and the connection configuration information of the slave playback device may also be simultaneously issued as slave playback device configuration information. For the master playback device or the slave playback device, the stereo configuration information and the connection configuration information described above may be issued separately.

The stereo playback control instruction may be generated based on the monaural playback instruction and the stereo playback identification information. For example, responding to the analyzed man-machine interaction instruction, obtaining the information matched with the monaural playing instruction, and then issuing the monaural playing instruction. For example, in response to the parsed man-machine interaction instruction, information matching with the stereo playing instruction is obtained, and then the stereo playing instruction is issued.

In one example, the audio data is obtained from the server in the form of an audio stream, and the stereo playback control instruction may include a resource access identifier of the server. The resource access identification may be issued by the server to the master playback device.

In another example, the audio data is obtained from the resource server in the form of an audio stream, and the stereo playback control instruction may include a resource access identifier of the application server (the application server may obtain the resource access identifier from the resource server). The resource access identifier may be issued by the application server to the master playback device for access by the master playback device.

In another example, the audio data may be stored in a master playback device that is local or may be stored in a slave playback device that is local (i.e., the master playback device is used to control playback by the slave playback device, but the audio data or audio data stream may come from the slave playback device in order to achieve separation of storage capability and playback control capability).

In another example, audio data may be transmitted in an end-to-end communication from a control terminal (e.g., a mobile terminal such as a cell phone or a center console of an internet of things device) that controls a master playback device and/or slave playback devices.

Further, the first channel and the second channel may be any two of a left channel, a right channel, a surround channel, and the like. For example, the first channel may be a left channel and the second channel may be a right channel. Alternatively, the first channel may be a right channel and the second channel may be a left channel.
