SYSTEM, METHOD, APPARATUS AND DEVICE FOR REPRODUCING HETEROGENEOUS CONTENTS, IN PARTICULAR MULTIMEDIA CONTENTS

摘要

The present invention concerns a system for reproducing contents of the heterogeneous kind, in particular multimedia contents distributed by a contents Supplier, comprising at least one device (14a, 14b,..., 14n) suitable for transmitting the contents to an apparatus (41a, 41b,..., 41n) for the contents enjoyment and a control central apparatus (12) connected to the device (14a, 14b,..., 14n) through connection means (18). The apparatus comprises at least one cryptographic processor designed for encrypting the contents and program modules designed for distributing the encrypted contents through the connection means (18) to a preset devices list. The device (14a, 14b,..., 14n), if belonging to the list, comprises at least one corresponding cryptographic processor designed for decrypting the encrypted contents on the basis of encryption/decryption keys exchanged with the central apparatus (12). The invention also concerns the apparatus (12), the device (14a, 14b,..., 14n) and a method for reproducing contents of the heterogeneous kind.
