摘要： In carrying out PWM-recording on optical disks, RESYNC BYTES including a bit compensation part, RESYNC detection part, and bit synchronization part are periodically inserted in the recorded data code stream. After encoding and at the time of decoding, RESYNC BYTES are detected by detection of the RESYNC detection part. The decoder is initialized by detecting the position of the bit synchronization part, and decoding is performed satisfactorily free from error. With this configuration, even for synchronization bytes having a comparatively long portion of consecutive code values, bit resynchronization is enabled free from mis-detection caused by peak shift. Even with the recording and reproducing characteristics with an un-symmetrical unerased area of the mark and space parts, the RESYNC detection part is fixed to either mark or space and RESYNC BYTES with little influence on an unerased area can be realized.

摘要： A digital video disk stores data codes and multifunctional synchronization codes in a data structure. The synchronization codes contain type information code identifying whether the synchronization code is located in a code sequence at the beginning of the data block, the beginning of a data block sector other than the first sector in the data block, the beginning of a line, or the middle of a line. The type information is expressed by two alternative patterns, type information code 1 and type information code 2, expressing the same information and differing in the number of is in the 5-bit sequence, i.e., an odd or even number of 1s. Which one of the two type information code pattern is used is selected according to the DSV so as to minimize bias in the dc component of the frame following the synchronization code.

摘要： A phase error between an information signal including a reference signal that can be detected asynchronously and a synchronized signal that is synchronously produced from the information signal is detected, and a signal in response to an absolute value of the phase error is produced. Further, a defect detecting signal is produced in response to the absolute value of the phase error. Therefore, whether a pulse signal exceeding a maximum value of the pulse width of the information signal, that is, a pulse signal exceeding the pulse width of the reference signal, is detected or not, it is possible to detect that the signal reproduction enters a defect region immediately after the entry. Accordingly, a defect with noise or a track jumping can be detected rapidly. Furthermore, an information transition interval of the information signal is measured for a prescribed period of time, and the defect detecting signal is terminated in response to a measured value of a time length of the reference signal that is detected in the prescribed period of time, in other words, the passing of the signal reproduction through the defect region is detected with reference to the synchronization of the reference signal. Therefore, pseudo locking of a PLL is avoided when it is operated again, and the PLL can be accurately re-locked.

摘要： Source data each consisting of m-bits can be converted into conversion codes each consisting of n (>m) bits with ease, and reverse conversion thereof can be performed with ease. The code conversion and the reverse conversion can be characterized in terms of a series of tables. The current input source data and the next input source data are respectively taken in by registers. Whether or not the run length at a connecting portion between consecutive source data satisfies conditions is determined by a control unit, and a table to be used is selected to finally obtain a conversion code.

摘要： Successive n-bit information words are converted into successive m-bit NRZI code words by assigning to each n-bit information word at least one m-bit code word having a respective NRZI disparity. The digital sum variation of the preceding m-bit NRZI code words is determined and the polarity of the conclusion of the immediately preceding m-bit NRZI code word is detected. An assigned m-bit code word is selected to represent the next n-bit information word as a function of the NRZI disparity of that code word, the determined digital sum variation and the detected polarity. The selected m-bit code word then is modulated in NRZI format such that the modulated code word has the same initial polarity as the detected polarity. The m-bit code word is selected such that its NRZI disparity, when combined with the determined digital sum variation, tends to prevent the digital sum variation from increasing.
