A content data acquisition system is disclosed. The content data acquisition system includes a broadcasting center for providing content data divided into partial data by distributing the partial data in one-way communication; and multiple data acquisition apparatuses each mounted to a vehicle and each capable of individually acquiring the partial data from the broadcasting center. One data acquisition apparatus mounted to one vehicle determines whether an amount of the already acquired partial data is enough to reconstruct the content data. When the amount of the already acquired partial data is determined to be not enough to reconstruct the content data, the one data acquisition apparatus acquires a remaining part of the partial data from another data acquisition apparatus mounted to another vehicle in inter-vehicle communication.
