Abstract
The broadcast station 1 provides the digital contents to be put on the air with the attributive information of the digital contents thereof. The selective information showing the user'"'"'s taste is set out in the filter unit 12. The filter unit 12 filters the attributive information on the basis of the selective information to select the digital contents which suits the user'"'"'s taste among the digital contents which were put on the air. According to the broadcast station 1, the user may listen and view the selected digital contents after recording the digital contents in the recording medium, or the user may listen and view the digital contents which suits the user'"'"'s taste among the digital contents which were put on the air.
