Master reproduction apparatus, slave reproduction apparatus, and emission methods thereof

A slave reproduction apparatus capable of executing synchronous reproduction of audio data together with a master reproduction apparatus, the slave reproduction apparatus comprising:

• one or more light emitting elements;
• a reception unit configured to receive audio data and illumination information, which is illumination information generated by the master reproduction apparatus having a plurality of light emitting elements and generated on a basis of analysis data of the audio data and in which light emission modes are associated with the plurality of light emitting elements, from the master reproduction apparatus;
• and
• a light emission control unit configured to cause the one or more light emitting elements to emit light on a basis of the received illumination information.

A light emission method by a master reproduction apparatus capable of executing synchronous reproduction of audio data together with one or more slave reproduction apparatuses, the method comprising:

• analyzing audio data to acquire analysis data;
• generating illumination information, in which light emission modes are associated with a plurality of light emitting elements provided in the master reproduction apparatus, on a basis of the acquired analysis data;
• transmitting the generated illumination information to the one or more slave reproduction apparatuses;
• and
• causing the plurality of light emitting elements to emit light in the light emission modes based on the illumination information.
