Abstract
A system for reproducing contents in a different device conveniently in use while protecting a copyright of digital contents includes a contents recording and transmission device, a reception and reproduction device, and an external storage medium having an ID. The external storage medium is connected to the reception and reproduction device. The ID is transmitted to the recording and transmission device, and ascertained. Then contents are delivered. The external storage medium has a list of contents stored therein. In the case where the contents are recorded in a plurality of devices, only a device to which the external storage medium is connected is made to be capable of reproducing the contents. A contents reproducing function is implemented as a program in a component form.
