Data decoding apparatus and method, charge information processing apparatus and method, data reproducing apparatus and method, electronic money, electronic use right, and terminal apparatus
First Claim
1. A data reproducing apparatus for reproducing compression encoded and/or encrypted digital data, comprising a decoding apparatus for decoding said digital data, and wherein said decoding apparatus has:
- decoding means for decoding the encoded or encrypted digital data;
memory means for storing monitoring right data; and
charge control means for, when said encoded or encrypted data is decoded, changing said monitoring right data in said memory means in accordance with an instruction of reproducing conditions information associated with said digital data, thereby performing a charging process.

Abstract
Reproduction data is supplied to a decoder and encryption is decoded. A reproducing conditions label is detected by a reproducing conditions label detecting unit. Compression encoding is decoded by a decompressor. A watermark detecting unit discriminates whether the reproducing conditions label has been falsified or not. In a listening right counter, each time the reproduction data is decoded, listening right data is changed. The listening right data transmitted from a prepaid data charger by an antenna and a communicating module is stored into a memory unit. An encrypting module and a decoding module are provided in the communicating module. In a watermark adding unit, a watermark is added to output data. The data is converted into an analog output by a D/A converter and outputted to the outside.

3. A reproducing apparatus comprising:
-
a decoding unit for performing a decoding process to compressed and/or encrypted data which was read out from a medium and includes data regarding reproducing conditions and;
a storing unit for storing monitoring right data; and
a control unit for, when said read-out data is decoded by said decoding unit in the case where said read-out data is data as a target of charging, performing a changing process to said monitoring right data stored in said storing unit on the basis of the data regarding the reproducing conditions separated by said decoding unit;
an operation unit which is operated by the user; and
a system control unit for supplying a control signal to said control unit on the basis of an input from said operation unit. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
