СПОСОБ И СИСТЕМА ОБМЕНА ИНФОРМАЦИЕЙ МЕЖДУ УСТРОЙСТВОМ ЗАПИСИ И/ИЛИ ВОСПРОИЗВЕДЕНИЯ И УДАЛЕННЫМ МОДУЛЕМ

摘要

The present invention relates to a communication system comprising a recording and/or reproducing device ( 11 ) able to read a data carrier, and a first remote unit ( 12 ) comprising additional data for the data carrier. The recording and/or reproducing device ( 11 ) and the first remote unit ( 12 ) communicate via a network. The communication system comprises a second remote unit ( 13 ) able to authenticate a trusted recording and/or reproducing device, and to make the trusted recording and/or reproducing device access the additional data. A trusted recording and/or reproducing device is able to detect the presence of the data carrier in the recording and/or reproducing device and to authenticate said data carrier.
