Abstract: The present technology relates to a signal processing apparatus, a signal processing method, and a program by which, in reproducing transmitted encoded data in real time, buffer overflow can be prevented from occurring on a reception apparatus side even if it is transmitted with a compression rate of the encoded data being varied in a manner that depends on communication condition. Encoded data including transmitted audio data is buffered by a reception buffer. At this time, the quantity of encoded data buffered by the reception buffer is managed in units of processing according to an encoding method. The present technology is applicable to a real-time content reproduction system utilizing a communication system.

Abstract: Techniques for wireless transmission of data are provided, in which data representing a plurality of frames of a time-sequential signal are encoded. The encoded data are temporarily retained in a memory buffer before wireless transmission. A current number of frames of the encoded data awaiting transmission is determined, and a compression rate is selected for encoding the next frame of data of the time-sequential signal based on the determined number of stored frames in the memory buffer. The selected compression rate is used to encode the next frame of the time-sequential signal, which is added to the encoded data stored in the memory buffer and wirelessly transmitted from the memory buffer. The present disclosure is applicable to a smartphone and a portable player, for example.

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.
