Abstract
Abstract In order to distribute music information from a central memory device (2) via a communications network (4) to a terminal (6), this information is organized in a digital music information object. The latter comprises a core having basic information relating to the music information object, as well as a number of additional layers having the actual music information. The core includes an encryption table, on the basis of which an encryption module (30) of the central memory device (2) and a decryption module (32) of the terminal (6) respectively encrypt and decrypt the music information object. Furthermore, an interpretation module (34) is provided in the terminal (6) for reproduction conditioning of the music information object, which interpretation module (34) accesses information for checking the authorized use of the music information object, which information is stored in an authorization device (36) and identifies the terminal or the consumer. The invention thus creates a technique for distribution of digital music information which on the one hand provides effective mechanisms for the protection of copyrights and on the other hand makes possible increased services for the consumer.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
228 words
A device for the distribution of music information comprising: a central memory device which is connected to a communications network and has a databank of digitized music information and, a terminal which is connected to the central memory device via the communications network, the central memory device being equipped with a retrieval module and the said modules having the capability to interact via the communications network in order to order and transmit selectively chosen music information, wherein the selectively chosen music information is organized with a defined format for transmission in a digital music information object, the format including a core and a number of additional layers, the core including at least one object identification code, object structure information, a consumer code and an encryption table and the one or more additional layers including the actual music information, wherein the central memory device has an encryption module for encryption of the music information object before transmission using the encryption table, and wherein the terminal has a decryption module for decryption of the music information object before its reproduction using the encryption table, an interpretation module for interpretation and reproduction conditioning of the music information object as well as an authorization device having identification information for identification of the terminal and of the consumer which is retrievable by the interpretation module and by the decryption module for authorization checking.
Claim 2
Independent Claim
228 words
A device for the distribution of music information comprising: a central memory device which is connected to a communications network and has a databank of digitized music information and, a terminal which is connected to the central memory device via the communications network, the central memory device being equipped with a retrieval module and the said modules having the capability to interact via the communications network in order to order and transmit selectively chosen music information, wherein the selectively chosen music information is organized with a defined format for transmission in a digital music information object, the format including a core and a number of additional layers, the core including at least one object identification code, object structure information, a consumer code and an encryption table and the one or more additional layers including the actual music information, wherein the central memory device has an encryption module for encryption of the music information object before transmission using the encryption table, and wherein the terminal has a decryption module for decryption of the music information object before its reproduction using the encryption table, an interpretation module for interpretation and reproduction conditioning of the music information object as well as an authorization device having identification information for identification of the terminal and of the consumer which is retrievable by the interpretation module and by the decryption module for authorization checking.
