Abstract
A plurality of kinds of LPCM signals/compression digital audio signals is switched to one another in transmission, thereby enabling audio reproduction to be satisfactorily carried out. A digital audio signal is transmitted to an external apparatus through a predetermined transmission path. Information associated with the digital audio signal to be next transmitted is added to the digital audio signal which is currently being transmitted. For example, first metadata exhibiting a transmission frequency of the digital audio signal, and second metadata exhibiting a data type of the digital audio signal are contained in the information.
Claims19
A transmission device, comprising:
- a transmission portion configured to transmit a digital audio signal to an external apparatus through a predetermined transmission path;
- and
- an information adding portion configured to add information associated with the digital audio signal to be next transmitted to the digital audio signal which is currently transmitted.
A transmission method, comprising:
- a transmission step of transmitting a digital audio signal to an external apparatus through a predetermined transmission path by a transmission portion;
- and
- an information adding step of adding information associated with the digital audio signal to be next transmitted to the digital audio signal which is currently transmitted.
A reception device, comprising:
- a reception portion configured to receive a digital audio signal from an external apparatus through a predetermined transmission path;
- and
- a processing portion configured to process the digital audio signal,
- wherein information associated with the digital audio signal to be next received is added to the digital audio signal which is currently received, and
- the processing portion processes the digital audio signal to be next received based on the information.
A reception method, comprising:
- a reception step of receiving a digital audio signal from an external apparatus through a predetermined transmission path by a reception portion;
- and
- a processing step of processing the digital audio signal,
- wherein information associated with the digital audio signal to be next received is added to the digital audio signal which is currently received, and
- in the processing step, the digital audio signal to be next received is processed based on the information.
