摘要： In order to reproduce data scrambled in respective manners to recordable recording medium, it is necessary to take the step of discriminating if the reproduction signal comes from any recording medium before descrambling the data. Further, before doing the control, it is necessary to discriminate if the data is copy-permitted or copy-prohibited. To accomplish this process, a data recording and reproducing apparatus includes a first reproducing unit 1, a second reproducing unit 7 for receiving the data processed by the first reproducing unit and executing the next reproducing process about the data, a first authenticating unit 4 for authenticating the first reproducing unit 1, a second authenticating unit 8 positioned in correspondence with the first authenticating unit and for authenticating the second reproducing unit. The data recording and reproducing apparatus provides different authenticating unit (5, 6, 9, 10) from the first and the second authenticating units so that those authenticating units may execute the corresponding authentications before descrambling the data.

摘要： A quick retry operation is possible by outputting an error flag pertaining to a sector after error correction processing of digital data. When an output of an error detection flag unit for a correction block indicates the existence of an uncorrectable error, the sectors are checked to see if the sectors corresponding to retrieved data include any error or not based on output from a sector error flag register B. When the sectors are judged as error, signals are retrieved again from a storage medium, re-stored in a memory, and an error correction processing is repeated again. The data such as that of P pictures or B pictures of MPEG which can be reproduced even with errors are output even when the error detection flag unit indicates the existence of the uncorrectable error. It enables identification of the sectors with the errors and simplifies the following operations pertaining to the error at a data receiving side by outputting the error flag along with the data.
摘要翻译：通过在数字数据的纠错处理之后输出属于扇区的错误标志，可以进行快速重试操作。当用于校正块的错误检测标志单元的输出指示存在不可校正的错误时，基于来自扇区错误标志寄存器B的输出来检查扇区以查看与检索到的数据对应的扇区是否包括任何错误。当扇区被判定为错误时，再次从存储介质中检索信号，重新存储在存储器中，并且再次重复错误校正处理。即使在错误检测标志单元指示存在不可校正的错误时，也输出诸如即使有错误也能够再现的MPEG数据，例如P图像或B图像。通过输出错误标志和数据，可以识别出现错误的扇区，并简化与数据接收端错误相关的以下操作。

摘要： In an apparatus for recording and reproducing a burst-like digital information signal (D), a method capable of predicting the time of occurrence of a header (3a) indicating the head of the first data (D) of a digital information signal (D) during its reproduction from a recording medium (110). The digital signal includes a plurality of data blocks (D) each including a header (3) indicative of the head of the block, and each header includes the address (A) of the block. During recording of the digital signal on the recording medium, a plurality of headers (3) which are substantially the same as the headers of the data blocks and including addresses (5) having given relations with the addresses (A) of the data blocks are inserted in a clock regenerating signal recorded before the digital signal for regenerating the clocks for the signal. The headers are inserted at a period equal to the length of each data block so as to be synchronized with the headers of the data blocks.
