摘要： Source data of m bits are converted into conversion codes of n (n>m) bits and the inversion is also possible. The kinds of 15-bit codes which are the conversion codes of tables A-F and the caracteristic parts of the contents of the codes are as follows: Table A: The number of kinds is 175 and the codes have "00" at their ends. Table B: The number of kinds is 81 and the codes have "0010" at their ends. Table C: The number of kinds is 81 and the codes have "0001" at their ends. Table D: The number of kinds is 34 and the codes have "001001" at their ends. Table E: The number of kinds is 86 and the codes have "00" at their leading edges and ends. Table F: The number of kinds is 39 and the codes have "00" at their leading edges and "0010" at their ends. The currently inputted source data are held in a register R0 and the next inputted source data are held in a register R1. A control unit judges whether or not the run length of the connection between the two sets of source data meets conditions and generates the final conversion codes by selecting a table used.

摘要： The information to be recorded is divided into 8-bit long data words. Each data word is then converted to 14-bit long code word. The code words are sequentially connected with a one-bit merging bit inserted between the code words to define a code bit sequence. The run-length of 0s in the code bit sequence is limited to be between 2 and 11. The one-bit merging bit normally takes a bit value of 0, but is changed to 1 when any one of the Tmin control or Tmax control is applied so as to accomplish the run-length limitation. The Tmin control is applied when the adjacent bits on both sides of the merging bit are 1s. The Tmax control is applied when trailing P bits of a code word preceding the merging bit and leading Q bits of a code word following the merging bit are all 0s, provided that P + Q >/= 11, and in this case, at least either one of the P bits and Q bits has a bit sequence of (00000), and the bit sequence (00000) is changed to (00100).

摘要： A data transmission apparatus for transmitting an original data has a converter for converting the original data to sequential data codes. The data code is formed by a combination of HIGH level binary codes and LOW level binary codes. The maximum length of continuous binary codes of one level, such as HIGH level, in the data codes is limited to Tmax, e.g., to 14T, in which T is a unit length representing one binary code, and the minimum length of continuous binary codes of one level, such as HIGH level, in the data codes is limited to Tmin, e.g., 3T. A generator generates a synchronization code. The synchronization code is formed by a combination of HIGH and LOW level binary codes. The synchronization code comprises an identifier having continuous binary codes of one level, such as HIGH level, with a predetermined length 16T which is 2T greater than Tmax. An inserter inserts the synchronization code intermittently in the sequential data codes.

摘要： A digital video disk stores data codes and multifunctional synchronization codes in a data structure. The synchronisation 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 1s 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： 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.
Features of the sorts and contents of 15-bit codes as conversion codes of tables A to F are summarized as follows.

Table A includes 175 sorts of codes
(having an code end expressed as ..00)
Table B includes 81 sorts of codes
(having an code end expressed as ...0010)
Table C includes 81 sorts of codes
(having an code end expressed as ...0001)
Table D includes 34 sorts of codes
(having an code end expressed as ...001001)
Table E includes 86 sorts of codes
(having an code top expressed as 00... and a code end expressed as ...00)
Table F includes 39 sorts of codes
(having a code top expressed as 00... and a code end expressed as ...0010)
A current input source data and a next input source data are respectively taken in by registers R0 and R1. Whether or not a 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.
