Abstract

Provided are a transmission device for transmitting a data signal to a reception device and a method for controlling the same. The present method for controlling a transmission device comprises; receiving function module information related to a codec supported by a reception device from the reception device while pairing with the reception device is performed; encoding a data signal on the basis of the received function module information; and transmitting the encoded data signal to the reception device.

Claims

1. A controlling method for a transmitting device that transmits a data signal to a receiving device, the method comprising:

receiving function module information with regard to a codec supported by the receiving device from the receiving device while performing paring with the receiving device;

encoding a data signal based on the received function module information; and

transmitting the encoded data signal to the receiving device.

2. The method as claimed in claim 1, wherein the function module information comprises at least one of information related to a plurality of function modules constituting the codec supported by the receiving device and operation information related to operations of the plurality of function modules according to an encoding mode.

3. The method as claimed in claim 2, wherein the encoding comprises determining a function module commonly supported by the transmitting device and the receiving device based on the function module information, and encoding the data signal based on the determined function module.

4. The method as claimed in claim 3, wherein the encoding further comprises selecting at least one of determined function modules based on user settings, a status of the transmitting device and a type of content, and encoding the data signal based on the selected function module.

5. The method as claimed in claim 2, wherein the plurality of function modules constituting the codec supported by the receiving device comprise at least one of a basic function module for a first function and an advanced function module for the first function, and

wherein the method further comprises determining an encoding mode depending on whether the basic function module and the advanced function module are supported.

6. The method as claimed in claim 5, wherein the determining comprises:

in response that both the receiving device and the transmitting device include an advanced function module, determining an encoding mode as a first mode for performing encoding by using the advanced function module, and

in response that at least one of the receiving device and the transmitting device does not include an advanced function module, determining an encoding mode as a second mode for performing encoding by using the basic function module.

7. The method as claimed in claim 1, wherein the receiving comprises receiving ID information with regard to the codec supported by the receiving device from the receiving device along with the function module information, and

wherein the determining comprises determining an encoding mode based on the received ID information with regard to the codec.

8. The method as claimed in claim 7, wherein the determining further comprises:

in response that the received ID information with regard to the codec is a predetermined first ID, determining an encoding mode as a first mode regardless of whether a basic function module and an advanced function module are supported, and

in response that the received ID information with regard to the codec is a predetermined second ID, determining the encoding mode as one of the first mode and a second mode depending on whether the basic function module and the advanced function module are supported.

9. The method as claimed in claim 1, further comprising:

in response that a bandwidth for transmitting the encoded data signal is reduced to a predetermined value or less while a data signal encoded by using a first codec is transmitted to the receiving device, encoding the data signal by using a second codec; and

transmitting the data signal encoded by using the second codec to the receiving device.

10. The method as claimed in claim 9, wherein the first codec is a codec for providing UHQ sound quality, and the second codec is a codec for providing HD sound quality.

11. A transmitting device for transmitting a data signal to a receiving device, comprising:

a communicator configured to perform communication with the receiving device;

an encoder configured to encode a data signal; and

a controller configured to;

control the communicator to receive function module information with regard to a codec supported by the receiving device from the receiving device while performing pairing with the receiving device,

control the encoder to encode a data signal based on the received function module information, and

control the communicator to transmit the encoded data signal to the receiving device.

12. The device as claimed in claim 11, wherein the function module information comprises at least one of information related to a plurality of function modules constituting the codec supported by the receiving device and operation information related to operations of the plurality of function modules according to an encoding mode.

13. The device as claimed in claim 12, wherein the controller is further configured to:

determine a function module commonly supported by the transmitting device and the receiving device based on the function module information, and

control the encoder to encode the data signal based on the determined function module.

14. The device as claimed in claim 13, wherein the controller is further configured to:

select at least one of determined function modules based on user settings, a status of the transmitting device and a type of content, and

control the encoder to encode the data signal based on the selected function module.

15. The device as claimed in claim 12, wherein the plurality of function modules constituting the codec supported by the receiving device comprise at least one of a basic function module for a first function and an advanced function module for the first function, and

wherein the controller determines an encoding mode depending on whether the basic function module and the advanced function module are supported.
