FIG. 3 is a flowchart of a method for playing audio data according to the some embodiments of the present invention. As shown in FIG. 3, the method for playing audio data provided in this embodiment includes the following steps:

Step S11: A mobile terminal searches for a multimedia device located in a same network as the mobile terminal, and performs mutual discovery with the multimedia device.

A mobile terminal 100 searches for a multimedia device 200 located in a same network as the mobile terminal, that is, the mobile terminal 100 searches for a multimedia device 200 served by a same gateway as the mobile terminal. In the embodiment, the network may be a WiFi network. In another implementation manner of this embodiment, the network may also be another type of wireless network, for example, a Bluetooth network. The mobile terminal 100 performs mutual discovery with the multimedia device 200, that is, the mobile terminal 100 discovers, based on a pre-configured protocol stack, all multimedia devices 200 supporting the protocol stack in the network, and correspondingly, the multimedia devices 200 also discover, based on the pre-configured protocol stack, all mobile terminals 100 supporting the protocol stack in the network.

Step S12: Determine a target multimedia device from the multimedia device according to a notification instruction triggered by a user, and send a notification message to the target multimedia device to instruct the target multimedia device to send currently played audio data to the mobile terminal.

Step S13: Receive and play the audio data sent by the target multimedia device.

According to the method for playing audio data provided in this embodiment of the present invention, a mobile terminal searches for a multimedia device located in a same network as the mobile terminal, and performs mutual discovery with the multimedia device； then, a target multimedia device is determined from the found multimedia device according to a notification instruction triggered by a user, and a notification message is sent to the target multimedia device, so as to instruct the target multimedia device to send currently played audio data to the mobile terminal； and lastly, the audio data sent by the target multimedia device is received and played. In this way, audio data in a multimedia device can be simultaneously played by using multiple mobile terminals, and the problem in the existing technology that a wireless earphone is unavailable in a long distance due to limitation from a frequency band and power can be solved, so that the convenience and efficiency of audio data playback can be improved.

FIG. 4 is a flowchart of a method for playing audio data according to the some embodiments of the present invention. As shown in FIG. 4, the method for playing audio data provided in this embodiment includes the following steps:

Step S21: A mobile terminal searches for a multimedia device located in a same network as the mobile terminal, and performs mutual discovery with the multimedia device by means of a Universal Plug and Play (UPnP) protocol stack.

In this embodiment, the UPnP protocol stack is configured in network modules of the mobile terminal 100 and the multimedia device 200. A UPnP is a set of network protocols put forward by the UPnP^TM Forum. The protocols aim to seamlessly connect various devices in a home network (data sharing, communication, and entertainment) and an enterprise network and simplify implementation of a relevant network. The UPnP is an international standard based on a multicast technology and a HyperText Transfer Protocol (HTTP) technology, and achieves this objective by defining and releasing a UPnP device control protocol that is based on open Internet and communications network protocol standards.

The mobile terminal 100 may perform mutual discovery with the multimedia device 200 by means of the UPnP protocol stack, and according to a discovery result, the mobile terminal 100 generates and displays a list including a multimedia device 200 supporting the UPnP protocol. Specifically, two cases may occur on the discovery based on the UPnP protocol stack: one is that after acquiring a control request, the mobile terminal 100 searches a current network for a corresponding available device (amultimedia device 200 supporting the UPnP protocol stack) ； and the other is that after accessing a network and acquiring an IP address, a multimedia device 200 begins to broadcast the access thereof in the network, that is, searches for a control request.

In another implementation manner of this embodiment, the mobile terminal 100 and the multimedia device 200 may also perform mutual discovery based on a Bonjour (zero configuration networking) protocol, another customized multicast protocol or Transmission Control Protocol/Internet Protocol (TCP/IP) data communication protocol, or another streaming media protocol.

Step S22: Determine a target multimedia device from the multimedia device according to a notification instruction triggered by a user and send an HTTP POST message to the target multimedia device.

The HTTP is a data transmission protocol in which rules about mutual communication between a browser and a World Wide Web server are set in detail and by means of which a World Wide Web text is transmitted through the Internet. A POST is an important composition part of the HTTP protocol, generally is used for sending a request to a destination, and is attached with a request entity.

Specifically, the mobile terminal 100 may receive a notification instruction triggered by a user on the list including a multimedia device 200 displayed on the mobile terminal 100, acquire a multimedia device at which the notification instruction is directed and use the multimedia device as a target multimedia device, and then send an HTTP POST message to the target multimedia device, so as to instruct the target multimedia device to send currently played audio data to the mobile terminal 100.

Step S23: Receive the audio data sent by the target multimedia device.

The audio data may be preferably in a pulse-code modulation (PCM) format. A PCM is a method for digitalizing an analog signal. With the PCM, the strength of a signal is divided into several segments according to a same spacing, and then the segments are quantized by using unique digital marks (generally binary) . The PCM is usually applied to a digital telecommunication system, and is also a standard form in computers and the CD digital audio red book.

Specifically, the target multimedia device receives the HTTP POST message sent by the mobile terminal 100, and according to the HTTP POST message, acquires currently played audio data in the target multimedia device, and sends the audio data to the mobile terminal 100.

Because the mobile terminal 100 can directly play PCM-format audio data, to improve universality of audio data playback, before sending the audio data, the target multimedia device may convert the acquired audio data into PCM-format audio data, so that the mobile terminal 100 is not limited by a playback format, and can still play the audio data from the target multimedia device even if having no decoding capability, which has advantages of a short system latency and good system real-time performance.

It may be understood that, the target multimedia device may also convert, according to a pre-configured rule, the audio data into another-given-format audio data and then send the another-given-format audio data to the mobile terminal 100, for example, to reduce a data transmission amount and improve a transmission speed, the audio data may be converted into MP3-format audio data having a small size； or, the target multimedia device may also acquire a device type of the mobile terminal 100, and then convert, according to the acquired device type of the mobile terminal 100, the audio data into audio data in a data format supported by the mobile terminal 100 and then send the audio data to the mobile terminal 100.

Step S24: Determine whether the audio data is in a PCM format.

If the audio data is in the PCM format, step S25 of detecting whether an external playback device is connected to the mobile terminal is performed.

The external playback device may include an earphone, a headset, a sound box, and the like.

If an external playback device is connected to the mobile terminal, step S26 of playing the audio data by using the external playback device is performed.

Specifically, if a detection result is that an external playback device is connected to the mobile terminal, the mobile terminal 100 transmits the received audio data to a data interface of the external playback device and outputs the audio data by using the external playback device.

If no external playback device is connected to the mobile terminal, step S27 of playing the audio data by using a loudspeaker of the mobile terminal is performed.

Specifically, if a detection result is that no external playback device is connected to the mobile terminal, the mobile terminal 100 transmits the received audio data to a data interface of a loudspeaker of the mobile terminal 100 and outputs the audio data by using the loudspeaker.

If the audio data is not in the PCM format, step S28 of acquiring a decoder corresponding to a format of the audio data and decoding the audio data by using the decoder is performed, and step S25 is performed.

Specifically, if a determining result is that the received audio data is not in the PCM format, the mobile terminal 100 may acquire a data format of the audio data, search for a locally installed decoding plug-in according to the data format, acquire a decoding plug-in corresponding to the data format, and decode the audio data by using the decoding plug-in. It may be understood that, if the decoding plug-in corresponding to the data format is not locally installed in the mobile terminal 100, the mobile terminal 100 may download, according to a pre-configured downloading rule or a downloading instruction triggered by the user, the decoding plug-in corresponding to the data format by using a network server and install the decoding plug-in, and then decode the audio data by using the decoding plug-in.
