Master reproduction device, slave reproduction device, and light emission methods therefor

A master reproduction device is capable of reproducing audio data synchronously with one or more slave reproduction devices. The master reproduction device is provided with a plurality of light emission elements, a generation unit, a transmission unit and a light emission control unit. The generation unit is configured to generate illumination information that associates light emission modes withthe plurality of light emission elements on the basis of analysis data obtained by analyzing the audio data. The transmission unit is configured to transmit the generated illumination information to the one or more slave reproduction devices. The light emission control unit is configured to cause the plurality of light emission elements to emit light in the light emission modes based on the illumination information. 该主再现设备能够与一个或多个从再现设备同步地再现音频数据。所述主再现设备设置有：多个发光元件、产生单元、发送单元和光发射控制单元。所述产生单元被配置为基于通过分析音频数据而获得的分析数据产生照明信息，所述照明信息将光发射模式与所述多个发光元件相关联。所述发送单元被配置为将所产生的照明信息发送到一个或多个从再现设备。所述光发射控制单元被配置为使得所述多个发光元件以基于所述照明信息的光发射模式来发射光。
