摘要： A reproducing apparatus has three reproducing modes that are a first mode, a second mode, and a third mode. In the first mode, when a program that has been reproduction restricted is tried to be reproduced, the reproducing operation is paused and the user is asked whether he or she wants to reproduce the program. Corresponding to the user's reply, the reproducing operation is performed or prohibited. In the second mode, a program that has been reproduction restricted is prohibited from being reproduced. In the third mode, a program that has been reproduction restricted is unconditionally reproduced. When the power of the apparatus is turned on at step S31, a prompt that causes the user to select one of the first mode, the second mode, and the third mode is displayed. At step S33, a process for designating a mode is performed. Information of the designated mode is stored in a nonvolatile memory.

摘要： A technique to determine whether a memory unit currently attached to a data processing unit is of a predetermined type or types. When the power of the data processing unit is turned on, it is determined whether or not a memory unit has been attached to the data processing unit. Thereafter, data is read from a boot block of the memory unit. With reference to identification information of the boot block, it is determined whether or not the attached memory unit is a first type memory unit, such as a security type memory unit. If the attached memory unit is a security type memory unit, an authenticating process is performed. After the memory unit has been authenticated, contents data may be recorded or reproduced. If the attached memory unit is not a security type memory unit, a message that represents that the memory unit cannot be used may be issued. If the data processing unit is a non-security type data processing unit, a normal operation is performed regardless of whether the memory unit attached thereto is a security type or non-security type memory unit.
摘要翻译：确定当前连接到数据处理单元的存储器单元是否是预定类型或类型的技术。当数据处理单元的电源接通时，确定存储单元是否已被附加到数据处理单元。此后，从存储器单元的引导块读取数据。参考引导块的识别信息，确定所附加的存储器单元是否是诸如安全型存储单元的第一类型存储单元。如果附加的存储器单元是安全型存储器单元，则执行认证处理。在存储器单元被认证之后，可以记录或再现内容数据。如果附加的存储器单元不是安全型存储器单元，则可以发出表示不能使用存储器单元的消息。如果数据处理单元是非安全类型的数据处理单元，则无论所附的存储单元是安全类型还是非安全型存储单元，都执行正常操作。

摘要： A security unit to prevent unauthorized retrieval of data includes an encrypting unit for encrypting data in accordance with commands received by the security unit, and a common register for storing both intermediate results and final results of the data encryption. A switching element operatively coupled to the register selectively outputs the contents of the register. The switching element is controlled to prevent external access to the intermediate results of the encryption. The security unit is particularly useful as part of a memory unit that is attachable to a recording/reproduction device such as a digital audio recorder/player.

摘要： The present invention provides a data processing method and apparatus capable of shortening the processing time required when editing previously encrypted track data. An example of a transfer of audio track data between a portable player and a storage device is provided. The track data is comprised of one or more parts, each of which in turn is comprised of a series of data blocks. Each block of the track data is encrypted prior to transfer using a block key. The block keys are determined in such a manner that subsequent editing of the track data which results in redistribution of the parts does not require full decryption of the data.
摘要翻译：本发明提供一种数据处理方法和装置，其能够缩短编辑之前加密的轨道数据所需的处理时间。提供了在便携式播放器和存储装置之间传送音轨数据的示例。轨道数据由一个或多个部分组成，每个部分又由一系列数据块组成。轨道数据的每个块在使用块密钥传输之前被加密。以这样的方式确定块密钥，使得导致部件的再分配的轨道数据的后续编辑不需要数据的完全解密。

摘要： A memory unit such as a memory card is removably attachable to a data processing unit such as a digital video recorder or an audio recording/reproducing unit. The memory unit includes a non-volatile memory, a security unit for protecting the security of data stored in the non-volatile memory, and an interface that receives control data from the data processing unit. The control data is either first control data for a read or write operation with respect to the non-volatile memory, or second control data (different from the first control data) for a security operation of the security unit. Thus, a security-type memory card is compatible with both a security type and a non-security type data processing unit.
