Abstract

A method for receiving audio data using Bluetooth Low Energy technology comprises: receiving, from a server device, a first advertisement message including information for providing an audio streaming service and a second advertisement message including synchronization information for synchronization between the client device and the server device; receiving, from the server device, a third advertisement message including transmission timing information of the audio data related to the audio streaming service, wherein audio data information for providing information on the audio data is included in at least one of the second advertisement message and the third advertisement message; receiving, from the server device, the audio data through isochronous channel; obtaining, from an user, specific information related to whether to permit a provision of the audio streaming service based on the audio data information; and decoding the audio data based on the specific information representing permission to provide the audio data.

First claim

The invention claimed is:

1. A method for receiving audio data using Bluetooth Low Energy technology, the method performed by a client device comprising:
receiving, from a server device, a first advertisement message including information for providing an audio streaming service;
receiving, from the server device, a second advertisement message including synchronization information for synchronization between the client device and the server device;
receiving, from the server device, a third advertisement message including transmission timing information of the audio data related to the audio streaming service,
wherein audio data information for providing information on the audio data is included in at least one of the second advertisement message and the third advertisement message;
receiving, from the server device, the audio data through isochronous channel;
obtaining, from an user, specific information related to whether to permit a provision of the audio streaming service based on the audio data information;
decoding the audio data based on the specific information representing permission to provide the audio data;
establishing a connection with the server device;
transmitting, to the server device, a read request message requesting to read state information of the audio data information stored in a first specific characteristic of the server device,
wherein the state information includes at least one of name information of the audio data, date information at which the audio data is stored in the first specific characteristic, or version information of the audio data; and
receiving, from the server device, a read response message including the status information.

2. The method of claim 1 ,
wherein data packet type of the second advertisement message is AUX_ADV_IND_PDU (packet data unit), and
wherein data packet type of the third advertisement message is AUX_SYN_IND_PDU.

3. The method of claim 1 , wherein the transmission timing information is included in Broadcast Isochronous Group (BIG) information.

4. The method of claim 1 ,
wherein the audio data information includes at least one of an identifier of the audio data information, length information on the audio data information, text information for providing the information on the audio data to the user in text form, or length information on the text information.

5. The method of claim 4 , further comprising:
outputting the information on the audio data in the text form on a display of the client device based on the text information.

6. The method of claim 5 ,
wherein base on the audio data information including a plurality of text information respectively related to a plurality of different languages, the audio data information further includes repetition number information on a number of times the plurality of text information is repeatedly output on the display.

7. The method of claim 1 ,
decoding the audio data information,
wherein only the audio data information among the audio data and the audio data information is decoded before the specific information is obtained from the user.

8. The method of claim 1 ,
wherein the synchronization information includes frequency hopping information for reception of the audio data.

9. The method of claim 1 , further comprising:
transmitting, to the server device, a write request message for requesting to write characteristic value related to changed audio data information to a second specific characteristic of the service device, in order to change the audio data information, based on based on the state information,
wherein the write request message includes a part of data consisting of the changed audio data information; and
receiving, from the server device, a write response message in response to the write request message.

10. The method of claim 9 ,
wherein each of the write request messages includes sequence number information for the part of the data.

11. The method of claim 1 , further comprising:
receiving, from a management server that manages a plurality of server devices including the server device, an entire synchronization information related to synchronization between the plurality of server devices and the client device,
wherein the entire synchronization information includes synchronization information for each of the plurality of server devices.

12. The method of claim 11 ,
wherein the synchronization information for each of the plurality of server devices is previously stored in the management server.

13. The method of claim 1 ,
wherein the audio data is audio data related to a specific program provided by the server device, and
wherein the audio data information indicates a title of the specific program.

14. The method of claim 1 , further comprising:
measuring a received signal strength of the first advertisement message,
wherein based on the received signal strength of the first advertisement message being greater than or equal to a specific threshold value, the first advertisement message is decoded.

15. A client device for receiving audio data using Bluetooth Low Energy technology, the client device comprising:
a transmitter for transmitting a radio signal;
a receiver for receiving a radio signal; and
a processor operatively coupled to the transmitter and the receiver,
wherein the processor is configured to control:
the receiver to receive, from the server device, a second advertisement message including synchronization information for synchronization between the client device and the server device;
the receiver to receive, from the server device, a third advertisement message including an indicator representing that audio data of the audio streaming service is grouped with audio data information for the audio data and transmitted;
the receiver to receive, from the server device, a third advertisement message including transmission timing information of the audio data related to the audio streaming service,
wherein audio data information for providing information on the audio data is included in at least one of the second advertisement message and the third advertisement message;
the receiver to receive, from the server device, the audio data through isochronous channel;
to obtain, from a user, specific information related to whether to permit a provision of the audio streaming service based on the audio data information;
to decode the audio data based on the specific information representing permission to provide the audio data;
to establish a connection with the server device;
the transmitter to transmit, to the server device, a read request message requesting to read state information of the audio data information stored in a first specific characteristic of the server device,
wherein the state information includes at least one of name information of the audio data, date information at which the audio data is stored in the first specific characteristic, or version information of the audio data; and
the receiver to receive, from the server device, a read response message including the status information.

16. The client device of claim 15 ,
wherein data packet type of the second advertisement message is AUX_ADV_IND_PDU (packet data unit), and
wherein data packet type of the third advertisement message is AUX_SYN_IND_PDU.
