A signal processing apparatus according to the present technology includes an information acquisition unit that acquires state information indicating a state of a user including a posture of the user, a tactile signal acquisition unit that acquires a reference tactile signal for performing tactile presentation to the user in a reference state, and an adjustment processing unit that generates an adjusted tactile signal by adjusting the reference tactile signal on the basis of the state information.

Signal processing apparatus, signal processing method, and signal processing system

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.

Electronic devices, method of transmitting data block, method of determining contents of transmission signal, and transmission/reception system

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.

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.

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.

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.

Transfer signals for respective blocks each including a plurality of frames are sequentially transmitted to a receiver side via a predetermined transfer line. The transfer signals include a predetermined number of channels of audio signals and a predetermined number of channels of tactile vibration signals. For example, the tactile vibration signals are generated on the basis of media signals associated with the audio signals. For example, configuration information of the predetermined number of channels of audio signals and the predetermined number of channels of tactile vibration signals is added to the transfer signals.
