    摘要： A data communication unit receives encrypted digital data via a network and records the digital data on a primary recording medium. The digital data, having been encrypted in different encryption methods according to the distributors, include attribute information indicating the encryption methods. The encryption method of the digital data is determined and the encrypted data is decrypted by an appropriate decryption unit. Identification information of a secondary recording medium or a playback apparatus is obtained according to whether the secondary recording medium is removable from the playback apparatus. A controller selects an encryption unit among a plurality of encryption units according to the obtained identification information. The selected encryption unit creates an encryption key according to the identification information and re-encrypts the digital data. A recording unit records the digital data on the secondary recording medium. An accounting unit charges according to accounting information in the attribute information.

    摘要： A semiconductor memory card comprising a control IC 302, a flash memory 303, and a ROM 304. The ROM 304 holds information such as a medium ID 341 unique to the semiconductor memory card. The flash memory 303 includes an authentication memory 332 and a non-authentication memory 331. The authentication memory 332 can be accessed only by external devices which have been affirmatively authenticated. The non-authentication memory 331 can be accessed by external devices whether the external devices have been affirmatively authenticated or not. The control IC 302 includes control units 325 and 326, an authentication unit 321 and the like. The control units 325 and 326 control accesses to the authentication memory 332 and the non-authentication memory 331, respectively. The authentication unit 321 executes a mutual authentication with an external device.

    摘要： An Audio Visual reproduction system for reproducing data from a composite media stream with various stream types including video, audio, and subtitle stream. The audio stream may include a plurality of interchangeable audio substreams and the subtitle stream may include a plurality of interchangeable subtitle substreams. Selected substreams may be simultaneously reproduced under user control. The reproduction includes a composite media stream separator unit, a video decoder unit, an audio decoder unit, and a subtitle decoder unit. The audio decoder unit can simultaneously decode a plurality of audio substreams to produce a plurality of audio outputs. The subtitle decoding unit can simultaneously decode a plurality of subtitle substreams to produce a plurality of subtitle outputs. A player and user model for simultaneously utilizing multiple substreams of a stream type contained within an application that conforms to a standard wherein only one substream of each stream type is used.
