    • A system and method of information dissemination that permits the user to listen to the specific content of information when and where he or she wants to. A radio or television receiver system receives information from an FM subcarrier, a television vertical blanking interval transmission, a television separate audio program transmission or a dedicated radio channel and stores the transmitted information in a memory. A user interface allows selection from the memory of the stored information via a set of menus controlling a hierarchical database, so as to access particular items of information. Typically the system includes RAM and/or a storage medium such as a digital audio tape, a magneto-optical mini-disk, a magnetic disk or optical disk, sufficient to store information for 10 hours of audio. A decompression device accepts the accessed compressed digital audio information items (which may have been encrypted) and transforms them into spoken speech. The user interface is either by voice or a single or multi-position switch allowing scanning through and selection from the menu items. The signal to be received is generated by converting analog audio signals into a digital audio data stream which may be encrypted. The encrypted digital data stream is compressed and inserted into the radio or television carrier via an FM Subcarrier, the television vertical blanking interval or the separate audio program channel of a television transmitter. The system is also capable of transmitting alphanumeric data and converting this alphanumeric data to a voice form using a speech synthesizer.
    • 一种信息传播的系统和方法,允许用户在他或她想要的时间和地点聆听信息的具体内容。 无线电或电视接收机系统从FM子载波接收信息,电视垂直消隐间隔传输,电视分离音频节目传输或专用无线电信道,并将发送的信息存储在存储器中。 用户界面允许通过控制分层数据库的一组菜单从存储器存储存储的信息,以便访问特定的信息项。 通常,该系统包括RAM和/或诸如数字音频磁带,磁光微型磁盘,磁盘或光盘的存储介质,其足以存储10小时音频的信息。 解压缩装置接受所访问的压缩数字音频信息项目(可能已被加密),并将其转换为口头语音。 用户界面是通过语音或单或多位置开关,允许从菜单项进行扫描和选择。 通过将模拟音频信号转换为可被加密的数字音频数据流来生成待接收的信号。 加密的数字数据流被压缩并经由FM子载波,电视垂直消隐间隔或电视发射机的单独音频节目频道插入到无线电或电视载体中。 该系统还能够发送字母数字数据并且使用语音合成器将该字母数字数据转换成语音形式。

    • In a digital information recording/reproducing apparatus, information recorded on a hard disk with copy restriction thereof is protected from being copied onto other hard disks by means of a PC, etc., to be produced a large number of illegal copies, i.e., infringing a copyright.The information is recorded onto a hard disk drive through encryption thereof, with using an identification being number unique thereto, when it is recorded onto the hard disk. With this, normal reproduction is prevented, since the drive identification number necessary for decryption is different from, even if it is copied onto the other hard disk. Also, a version information of the hard disc is memorized in an information management circuit. When the information is illegally copied onto the other hard disc, the version information is changes; therefore it does not coincide with the version information memorized in the information management circuit. With this, illegal reproduction of the information copied can be prohibited in the reproducing operation.
    • 在数字信息记录/再现装置中,通过PC等来保护记录在具有其复制限制的硬盘上的信息被保护以被复制到其他硬盘上,以产生大量的非法拷贝,即侵权 版权。 当通过其加密将信息记录在硬盘驱动器上时,当将其记录到硬盘上时,使用其中唯一的标识。 因此,由于解密所需的驱动器识别号码即使被复制到另一个硬盘上也是不同的,所以防止正常再现。 此外,硬盘的版本信息被存储在信息管理电路中。 当信息被非法复制到另一个硬盘上时,版本信息是变化的; 因此与信息管理电路中存储的版本信息不一致。 由此,在再现操作中可以禁止复制的信息的非法再现。

    • The media inherent key storing unit 220 prestores an inherent key Ki, the conversion unit 230 generates an encrypted inherent key Ji from the inherent key read from the media inherent key storing unit 220, the random number generating unit 331 generates a random number R1, the encryption unit 252 generates an encrypted random number S1, the decryption unit 333 generates a random number R′1 from the encrypted random number R1, and the mutual authentication control unit 334 compares the random number R′1 with the random number R1 and, if the random number R′1 matches the random number R1, judges that the memory card 200 is an authorized device. If the memory card 200 and the memory card writer have successfully authenticated each other, the memory card writer encrypts a content using a decrypted inherent key. If the memory card 200 and the memory card reader have successfully authenticated each other, the memory card reader decrypts an encrypted content using the decrypted inherent key.
