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.
Claims36
A transmission device, comprising:
- a transmission portion configured to transmit a first digital audio signal to an external apparatus via a transmission path;
- and
- an information adding portion configured to add information associated with a second digital audio signal, to the transmitted first digital audio signal, wherein
- the second digital audio signal is transmitted subsequent to the transmission of the first digital audio signal, and
- the information comprises time information that includes a transmission start timing of the second digital audio signal.
