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: 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: Provided is a transmission device that sequentially transmits an audio signal in which predetermined units are arranged successively 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, at the reception side, reproduction of the compressed audio signal and/or the linear PCM signal is added.

Abstract: A new interface is provided that supports simultaneous transmission of an audio signal and a MIDI signal. Signals consecutive in predetermined units are transmitted to a reception side via a predetermined transmission path. The signals consecutive in the predetermined units include a signal of a first predetermined unit of the predetermined units including an audio signal and a signal of a second predetermined unit of the predetermined units including a MIDI signal. For example, the audio signal is a linear PCM signal constituting a stereo 2-channel audio signal. For example, the MIDI signal includes packet data of a predetermined length, and the packet data of the predetermined length is divided into a plurality of pieces, and transmitted by being included in signals of a plurality of pieces of the second predetermined units.

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: There is provided a transmission signal to enable tactile presentation at more positions than the number of channels of a tactile vibration signal that can be transmitted. The transmission signal includes audio signals of a predetermined number of channels and tactile presentation signals of a predetermined number of channels and to which metadata designating the tactile presentation position targeted by each of the tactile presentation signals of the predetermined number of channels is added is generated. The transmission signal is transmitted to a reception side via a predetermined transmission path. For example, the metadata is dynamically changed to dynamically change the tactile presentation position targeted by each of the tactile presentation signals of the predetermined number of channels.
