To provide a digital video content distribution system which does not make a user feel unpleasant as much as possible.

When a state (vehicle travel state) where it is not preferable that the digital video content is displayed on a front-seat display is put in during display of the digital video content on the front-seat display and a rear-seat display, on-screen display of a map image is performed on the front-seat display. There is therefore no change in distribution route of the digital video content and authentication processing for whether the distribution route is adequate is not necessary. The digital video content is consequently displayed on the rear-seat display without any break and a user on a rear seat does not feel unpleasant.
