Abstract: Damaging a device that is not compatible with a functional extension is to be avoided. A signal is transmitted to an external device through a transmission channel. A data block containing capability information indicating existence/non-existence of compatibility with an extended function is received from the external device through the transmission channel. A layer field that indicates the connection layer is provided in this data block. A check is made to determine whether all the devices existing in the path are compatible with the extended function based on the value of the layer field provided in the data block, and the contents of the transmission signal are then determined.

Abstract: A tactile vibration signals is satisfactorily transmitted. A transmission signal for each block including a plurality of frames for an audio signal is sequentially transmitted to a receiving side via a predetermined transmission line. The transmission signal includes a tactile vibration signal of a predetermined number of channels. For example, the tactile vibration signal is generated on the basis of a media signal associated with the audio signal. For example, configuration information of the tactile vibration signal of the predetermined number of channels is added to the transmission signal. For example, the configuration information is added by use of a predetermined bit area of a channel status configured for each block.

Abstract: A signal is transmitted at a high speed in a direction opposite to a transmitting direction of a main large-capacity channel. A first transmitting unit transmits a first signal including a clock component to an external device through a transmission path as a differential signal. A second transmitting unit superimposes a second signal including a clock component on the transmission path as an in-phase signal to transmit to the external device. A state notifying unit communicates with the external device through a pair of differential transmission paths included in the transmission path and notifies the external device of a connection state of its own device by a DC bias potential of at least one of the pair of differential transmission paths.

Abstract: It is made possible that, in a case where a compressed audio signal and a linear PCM signal are transmitted simultaneously, reproduction control of the compressed audio signal and/or the linear PCM signal is favorably performed on the reception side.
An audio signal in which predetermined units are arranged successively is transmitted sequentially to the reception side through a predetermined transmission line. For example, the audio signal of each predetermined unit is a mixture signal of a compression audio signal and a linear PCM signal. Further, for example, in the audio signal in which the predetermined units are arranged successively, an audio signal of predetermined units including a compressed audio signal and an audio signal of predetermined units including a linear PCM signal are arranged alternately. To the audio signal, reproduction control information for controlling reproduction of the compressed audio signal and/or the linear PCM signal is added.
