The content distribution server 6 includes a remaining time list inquiry unit 61, a remaining time list obtaining unit 62, a content database 63, a content extracting unit 64, a content providing unit 65, and a selection result receiving unit 66.

The processing units 61 to 65 are the same as the content distribution server 6 according to the first embodiment shown in FIG.

The content extraction unit 64 outputs the list of contents extracted from the content database 63 to the content providing unit 65, and the content providing unit 65 transmits the content list to the in-vehicle device 2.

(4) The selection result receiving unit 66 receives, from the in-vehicle device 2, a result of selecting a content from the content list.

The content extracting unit 64 extracts the content selected by the user from the content database 63 according to the selection result, and the content providing unit 65 transmits the extracted content to the vehicle-mounted device 2.

(4) The content extracting unit 64 functions as a preference obtaining unit, and learns the user's preference of the content by learning the selection result of the content. For example, the content extraction unit 64 may determine that the category information of the content selected a certain number of times or more is content that the user likes. Thereby, the content extracting unit 64 acquires the content preference that the user likes. The content extraction unit 64 registers the acquired preference in the content database 63 as preference information.
