Abstract
A content distribution apparatus has a receiver for receiving an input audio signal, and a generator for generating a modulated audio signal having an amplitude change corresponding to a frequency of gamma waves by performing a modulation process including amplitude modulation on the input audio signal received by the receiver, and an output for outputting a content and modulation information in association with each other, the content including the modulated audio signal generated by the generator, the modulation information being related to the modulation process performed to generate the modulated audio signal.
Claims11
A content distribution apparatus comprising:
- a memory that stores instructions;
- and
- a processor that executes the instructions stored in the memory to:
- receive an input audio signal;
- generate a modulated audio signal having an amplitude change corresponding to a frequency of gamma waves by performing a modulation process including amplitude modulation on the received input audio signal;
- and
- output a content and modulation information in association with each other, the content including the modulated audio signal generated, the modulation information being related to the modulation process performed to generate the modulated audio signal.
A content playback apparatus comprising:
- a memory that stores instructions;
- and
- a processor that executes the instructions stored in the memory to:
- acquire modulation information associated with a modulated audio signal having an amplitude change corresponding to a frequency of gamma waves, the modulation information being related to a modulation process including amplitude modulation performed to generate the modulated audio signal;
- and
- control, based on the modulation information, playback of a content including the modulated audio signal associated with the acquired modulation information.
Cognitive function improvement system comprising a content distribution apparatus and a content playback apparatus, wherein
- the content distribution apparatus comprises:
- a memory that stores instructions;
- and
- a processor that executes the instructions stored in the memory to:
