摘要 |
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.
