摘要

Provided is an audio visual environment control system capable of realizing optimal audio-visual environment illumination control in accordance with the illumination condition upon shooting of a display image. A data transmission device comprises: a data multiplexing portion for multiplexing the shooting illumination data indicating the illumination condition at the shooting of each scene of video data on the video data, and a transmitting portion for modulating and transmitting the video data on which the shooting illumination data is multiplexed. A data receiving apparatus which receives the data comprises: a data separating portion 22 for separating the shooting illumination data from the video data, a CPU 23 for controlling the illuminating light of an illuminating device 27 in accordance with the illumination data, and an illumination control data generating portion 24.
