Upon reception of content information (step S), a control unit decides a different notification sound in accordance with an identifier attached to the received content information (step S). The control unit causes a reproduction unit () to reproduce the decided notification sound. Thus, the user can guess the content of the received content information.

Vehicle-mounted device and audio reproduction method

A road-vehicle communication system enabling resumption of the transmission/reception from the rest of data between the vehicle and the road if the transmission/reception is interrupted. Specifically, the road-vehicle communication system includes a roadside apparatus for distributing a content and a vehicle-mounted device which can play a distributed content, the roadside apparatus is connected communicatively with the vehicle-mounted device, and a series of contents are distributed from the roadside apparatus to the vehicle-mounted device. The roadside apparatus includes a control unit for determining a content which the roadside apparatus starts transmitting to the vehicle-mounted device, which is a communication party, from among the series of contents and distributing the other contents succeeding the determined transmission start content. Thus, if the transmission/reception of data between the road and vehicle is interrupted, the transmission/reception can be resumed.

Road-vehicle communication system

Reproduction is performed so that the user can grasp the details of content information on long sentence reading the reproduction of which has been suspended. If an vehicle-mounted device () receives content information with higher priority of the reproduction than that of the content information on the long sentence reading during the reproduction of the content information on the long sentence reading received from a center apparatus by a reproduction section (step S; Y), the vehicle-mounted device () allows the control of a control unit to suspend the reproduction of the content information on the long sentence reading (step S) and to start the reproduction of the content information with higher priority (step S). If the reproduction ends, the vehicle-mounted device () allows the reproduction means to resume the suspended reproduction of the content information on the long sentence reading (step S).
