摘要： A video signal input-output circuit and a recording-reproduction apparatus in which a digitally compressed video signal input in packet form can be recorded and reproduced efficiently and in stable fashion. In this apparatus, a clock reference is detected from a packet signal containing the clock reference and a digitally compressed video signal, a time stamp for a packet is generated using a clock signal in phase with the clock reference and added to the particular packet, and the packet signals with the time stamp added thereto are recorded closely to each other in a data storage element such as a magnetic recording medium. At playback, the packet interval is output by being restored to the original length on the basis of the time stamp added to the packet in store.

摘要： 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.
摘要翻译：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。

摘要： If content is transmitted/received through a digital signal bus, protection of copyright causes a problem because of no deterioration in quality. Accordingly, authentication is required. The quantity of information to be processed is, however, so large that a long time is required for authentication. Accordingly, both achievement of handling property as in conventional analog connection and protection of copyrighted content without user's awareness become an object. The foregoing object can be achieved by authentication which is executed, for management of copyright, among apparatuses connected to the digital signal bus when the apparatuses are powered on or connected to the digital signal bus or when an input terminal connected to the digital signal bus is selected. The object can be further achieved by an encryption key shared among these apparatuses.
摘要翻译：如果通过数字信号总线发送/接收内容，则由于质量的劣化，版权保护造成问题。因此，需要认证。然而，要处理的信息量如此之大以至于需要长时间的认证。因此，在传统模拟连接中实现处理属性和保护没有用户意识的版权内容成为目的。上述目的可以通过在设备上电或连接到数字信号总线时连接到数字信号总线的设备之间执行的用于管理版权的认证来实现，或者当连接到数字信号总线的输入端子是选择。可以通过这些装置之间共享的加密密钥来进一步实现该目的。

摘要： In order to provide a recording and reproducing device that allows a user to select and manage arbitrary play lists, a unit of management for managing all registered play list information and an upper management hierarchical level are added. The unit of management is adapted to be handled on the same level with unified information that indicates a reproduction range of all AV data. User-defined unified information is adapted to be handled on the added management hierarchical level. The user-defined unified information is formed to allow arbitrary reproduction ranges contained on a lower hierarchical level to be registered.
