Transmission apparatus, transmission method, reception apparatus, and reception method for designating tactile presentation positions

A transmission method comprising:

• generating a transmission signal including audio signals of a predetermined number of channels and tactile presentation signals of a predetermined number of channels and to which metadata designating a tactile presentation position targeted by each of the tactile presentation signals of the predetermined number of channels is added;
• transmitting the transmission signal to a reception side via a predetermined transmission path;
• and
• performing fade-out and fade-in processing on the tactile presentation signals of the predetermined number of channels or inserting a mute signal into the tactile presentation signals of the predetermined number of channels when changing the metadata from a first state to a second state.

A reception apparatus comprising:

• a reception unit configured to receive, from a transmission side via a predetermined transmission path, a transmission signal including audio signals of a predetermined number of channels and tactile presentation signals of a predetermined number of channels and to which metadata designating a tactile presentation position targeted by each of the tactile presentation signals of the predetermined number of channels is added;
• and
• a processing unit configured to extract and output the audio signal of the predetermined channel from the transmission signal, extract the tactile presentation signal of the predetermined channel from the transmission signal, and output each of the tactile presentation signals of the predetermined channels as a tactile presentation signal of a target tactile presentation position on a basis of the metadata,
• wherein the processing unit is further configured to perform fade-out and fade-in processing on the tactile presentation signals of the predetermined number of channels or insert a mute signal to the tactile presentation signals of the predetermined number of channels when the metadata is changed from a first state to a second state, and
• wherein the reception unit and the processing unit are each implemented via at least one processor.
