Query for other media devices to try to connect.

Still another object of the present invention is to provide an audio network construction method for a multi-domain media device, wherein when a media device is connected to an audio network, the controller can request other media devices to join the same device. In the audio network.

To achieve the above objective, the present invention provides an audio network construction method for a multi-domain media device, in which a plurality of media devices connectable to multiple domains are added to the same audio network, and the media devices are connected to a controller. First, each media device first establishes an audio network to optimize the audio network information, including setting the network configuration, intelligently searching for clean frequency bands, selecting media formats, and storing audio network information; The audio network connection of the at least two media devices causes at least one first device to join the audio network of the other second device, and the controller first sends a connection command to the first device, requesting the first device to join the first device. In the audio network of the second device, the first device queries the second device for the audio network information stored therein, obtains the audio network information of the second device, and attempts to join the audio network of the second device. Joining means that the first device and the second device representing different domains establish an audio network.

The purpose, technical content, features and effects achieved by the present invention will be more readily understood by the detailed description of the embodiments.

The present invention provides a method for constructing an audio network of a multi-domain media device. The architecture is as shown in FIG. 1A and FIG. 1B, and a plurality of media devices 12 connectable to multiple domains are added to the same audio network 16, and the media is The device 12 is connected to a controller 14. Since the media device 12 can simultaneously connect the public domain 10 and the audio network 16, the media device 12 of the present invention must be able to connect multiple domains at the same time. The media device 12 is an audio, wireless speaker, broadcast device or music player.

In the present invention, at least one media device is to be added to the audio network of another media device, for example, to add at least one first device to the audio network of the second device, firstly, the audio of the second device needs to be established. The network then allows the first device to connect to the audio network of the second device.

Please refer to FIG. 2, which is a flowchart of establishing an audio network in the audio network construction method of the multi-domain media device of the present invention. In step S10, each media device first establishes an audio network, and then the audio network information. Optimized, including smart searching for clean frequency bands (step S12), setting network configuration (step S14), selecting media format (step S16), etc., for example, assuming that there are many devices for transmitting data using audio signals, it will occupy In some frequency bands, the media device needs to search for unused frequency bands to establish an audio network, and avoid sharing noise with other devices, such as MP3, MP4, ogg, flac, alac, aac, WMA, 3gp, etc. The file format; after the audio network is established, the media device stores the audio network information, as in step S18, for other media devices to query for use.

FIG. 3 is a flow chart of connecting audio network information in the audio network construction method of the multi-domain media device of the present invention. To connect the audio networks of at least two media devices, for example, to add the first device to the audio network of the second device, the first device may have more than one, and the first device and the second device are all in the first picture. In the device in the media device 12, in step S20, the controller first sends a connection command to the first device, requesting the first device to join the audio network of the second device; then, the first device will go to the first device in step S22. The second device queries the audio network information stored by the device. If the query is successful, the first device obtains the audio network information of the second device in step S26, and attempts to join the audio network of the second device in step S28. Step S30 represents that the first device and the second device of the different network domain establish an audio network, and the first device stores the audio network information of the second device for other media devices to query, and will try to connect in step S32. The result of the line is reported to the controller; if the query fails in step S22, the audio network is not successfully established on behalf of the second device, and is not added to any audio network, as described in step S24.

Since each media device first establishes an audio network, the controller can add other media devices to the same audio network through the media device as long as it detects that the media device is connected to the audio network. Compared with the prior art, in which the controller needs to obtain the network information of the audio network creator and then ask other devices to join the audio network, the controller in the present invention only needs to send the connection instruction to other devices, Need to obtain the network information of the audio network creator, this network information will be queried by the other device to the audio network creator, and will be returned to the controller regardless of whether other devices join the audio network, so for control For the device, it only needs to issue a connection command that requires one device to join the audio network of another device, and does not need to obtain any audio network information and send it to other devices, the process is simple, the number of data exchanges is reduced, and the user is more suitable. Operational behavior.

In summary, the audio network construction method of the multi-domain media device provided by the present invention establishes an audio network for media devices in the same public domain, because the media devices in the audio network are also common. The network domain is connected to the controller, so each media device is a multi-domain device. The present invention sends a connection command to the media device by the controller, and requests it to join the audio network of another device, and the media is The device obtains the audio network information from another device by itself, and the controller does not need to obtain the audio network information from the audio network creator, which not only saves complicated data exchange, but also conforms to the user's operation behavior.
