Abstract

It is possible to rapidly transfer a content from a content server device to an on-vehicle player while protecting the copyright of the content. A content server device (10) includes: a unique information holding unit (103) holding unique information on an on-vehicle player device (20); a content acquisition unit (101) for acquiring a content from outside; an encryption unit (104) for encrypting the acquired content into an encrypted content by using the unique information prior to a transmission request from the on-vehicle player device (20); an accumulation unit (105) for accumulating the encrypted content; and a transmission unit (107) for transmitting the encrypted content accumulated according to the transmission request from the on-vehicle player device (20). The on-vehicle player device (20) has a storage medium (208) for storing the encrypted content received and a decryption unit (209) for decrypting the encrypted content stored, according to the reproduction request given from outside.

Description

Technical field [0001] The present invention involves content server devices, vehicle player devices, and systems with these devices. It especially involves the technology that quickly transmits digital content that requires copyright protection from the content server device to the car player device. Background technique [0002] In the past, such as driving or getting off and off work, they stored favorite music in storage media such as CD (Compactdisk) or MD (Mini Disk) and brought them to the car. The practice of enjoying music in the car was widely used. [0003] For example, in the patent literature 1, support for more convenient information retrieval and regeneration systems such as audiovisual music in the car.This information retrieval regeneration system is composed of wireless -connected home servers and vehicle terminals.Through radio communication, the car terminal brows out the spectacle of music in the home server, and gets the hopes from the home server to regene...
