摘要： A DSV control bit determining/inserting unit 11 inserts DSV control bits for execution of DSV control into an input data string and outputs the data string including the DSV control bits to a modulation unit 12. The modulation unit 12 converts the data string with a basic data length of 2 bits into variable length code with a basic code length of 3 bits in accordance with a conversion table and outputs the code resulting from the conversion to a NRZI encoding unit 13. The conversion table used by the modulation unit 12 includes substitution codes for limiting the number of consecutive appearances of a minimum run to a predetermined value and substitution codes for keeping a run length limit. In addition, the conversion table enforces a conversion rule, according to which the remainder of division of the “1” count of an element in a data string by 2 having a value of 0 or 1 shall always be equal to the remainder of division of the “1” count of an element in the code resulting from conversion of the data string by 2.

摘要： The invention relates to an information processing apparatus and method by which it is made possible to efficiently provide change information of broadcast contents in accordance with the necessity of a user. A server 2 compares contents information acquired from a contents information production apparatus 5 and contents information prior by one generation stored in a contents information database 11. If a result of the comparison proves that the contents information has a change, the contents information is registered with a change code added thereto into a change information database 12. When contents information of broadcast contents corresponding to reservation contents information transmitted from a broadcast receiving and recording apparatus 3-1 is found in the change information database 12, the server 2 transmits change information to the broadcast receiving and recording apparatus 3-1. The invention can be applied to a system which provides contents information through the Internet.

摘要： Clock is reproduced stably. If data (limiting code) containing a plurality of consecutive minimum inversion interval Tmin is contained in the data inputted from a shift register, a Tmin consecution limiting code detection unit detects such consecutive interval. A constraint length judgement unit judges the constraint length i to be the constraint length corresponding to the code for limiting the constraint length i when a detection signal is inputted from the Tmin consecution limiting code detection unit, and outputs the judged constant length to a multiplexer. The multiplexer selects the output of a converter corresponding to the constraint length supplied from the constraint length judgement unit out of converters 14-1 to 14-r, and supplies the selected output to a run detection processing unit through a buffer.

摘要： An information recording and reproducing apparatus provided with the maximum likelihood decoding utilizes a standard deviation of difference metrics as an estimating function for adjustment for the purpose of achieving a short-time adjustment with a small number of samples. A regenerative clock and a reproduction signal outputted from the information recording and reproducing apparatus are supplied to a maximum likelihood decoder. Based on the estimated recorded series detected by the maximum likelihood decoder at a low error rate, a recording state detector generates a recorded bit series. Then, a standard deviation calculator operates to select a difference metric delayed by a detected amount by a display line from the difference metrics outputted from the maximum likelihood decoder and derives the standard deviation of the difference metrics. Then, a .sigma..sub.-- .DELTA.m/.mu..sub.-- .DELTA.m minimizing controller operates to adjust a shift of a sampling phase and a track offset of the information recording and reproducing apparatus so that the standard deviation .sigma..sub.-- .DELTA.m is made minimal.

摘要： The present invention radiates laser light to an optical disc 1, detects a tracking error signal based on a concave and convex form of a track by means of its reflection light, applies a tracking servo so as to selectively follow any one track of a concave track or a convex track of a spot of the laser light by using this tracking error signal, continuously stores modulation data in a memory 13, and then records on the track to which the tracking servo is applied. Further, the present invention reverses a polarity of the tracking error signal when carrying out a track jump from a track, on which current data is recorded, to an adjacent track, applies the tracking servo to a new track, reads out the modulation data from the memory 13, and records the data on the new track. Accordingly, the present invention can record the data on the concave track and the convex track while carrying out the track jump.
