Abstract

The present technology relates to a data processing apparatus, a data processing method, and a program that are capable of preventing output of data from being interrupted on a reception side, the data being wirelessly transmitted and received by the reception side.Control information for controlling a method of using data is generated by a reception side, the data being wirelessly transmitted and received by the reception side, and the control information is added to data to generate data-with-control-information. A method of using data is controlled on the basis of control information included in data-with-control-information for controlling the method of using data, the data-with-control-information being acquired by adding the control information to data, the data-with-control-information being wirelessly transmitted, and data whose use method is controlled is output on the basis of the control information.

First claim

The invention claimed is:

1. A data processing apparatus comprising:
a data control unit configured to control a process of using data based on control information associated with the data, the data and the associated control information being wirelessly received; and
a data output unit configured to output the data whose use is controlled, based on the control information;
wherein the control information used to control the process of using data is based on a characteristic amount representative of a characteristic of the data and wherein the data includes LPCM (Linear Pulse Code Modulation) data and the characteristic amount is generated from results of processing performed on a frame of the LPCM data acquired when SBC (Subband Code) encoding is performed on a transmission side.

2. The data processing apparatus according to claim 1 , wherein the process of using data includes loading all or part of the data into a buffer.

3. A data processing method comprising:
controlling a process of using data based on control information associated with the data, the data and the associated control information being wirelessly received; and
outputting the data whose use is controlled, based on the control information;
wherein the control information used to control the process of using data is based on a characteristic amount representative of a characteristic of the data and wherein the data includes LPCM (Linear Pulse Code Modulation) data and the characteristic amount is generated from results of processing performed on a frame of the LPCM data acquired when SBC (Subband Code) encoding is performed on a transmission side.

4. The data processing method according to claim 3 , wherein the process of using data includes loading all or part of the data into a buffer.

5. A non-transitory computer-readable medium containing instructions that, when executed by a processing device, implement:
a data control unit configured to control a process of using data based on control information associated with the data, the data and the associated control information being wirelessly received; and
a data output unit configured to output the data whose use is controlled, based on the control information;
wherein the control information used to control the process of using data is based on a characteristic amount representative of a characteristic of the data and wherein the data includes LPCM (Linear Pulse Code Modulation) data and the characteristic amount is generated from results of processing performed on a frame of the LPCM data acquired when SBC (Subband Code) encoding is performed on a transmission side.

6. A data processing apparatus comprising:
a control information generation unit configured to generate control information for controlling use of data by a reception side and to associate the control information with the data; and
a transmission unit configured to wirelessly transmit the data and the associated control information to the reception side,
wherein the control information for controlling use of data by the reception side is based on a characteristic amount representative of a characteristic of the data and wherein the data includes LPCM (Linear Pulse Code Modulation) data and the characteristic amount is generated from results of processing performed on a frame of the LPCM data acquired when SBC (Subband Code) encoding is performed on a transmission side.

7. A data processing method comprising:
generating control information for controlling use of data by a reception side and associating the control information with the data; and
wirelessly transmitting the data and the associated control information to the reception side,
wherein the control information for controlling use of data by the reception side is based on a characteristic amount representative of a characteristic of the data and wherein the data includes LPCM (Linear Pulse Code Modulation) data and the characteristic amount is generated from results of processing performed on a frame of the LPCM data acquired when SBC (Subband Code) encoding is performed on a transmission side.

8. A non-transitory computer-readable medium containing instructions that, when executed by a processing device, implement:
a control information generation unit configured to generate control information for controlling use of data by a reception side and to associate the control information with the data; and
a transmission unit configured to wirelessly transmit the data and the associated control information to the reception side,
wherein the control information for controlling use of data by the reception side is based on a characteristic amount representative of a characteristic of the data and wherein the data includes LPCM (Linear Pulse Code Modulation) data and the characteristic amount is generated from results of processing performed on a frame of the LPCM data acquired when SBC (Subband Code) encoding is performed on a transmission side.
