Abstract
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 a continuous binary codes of one level, such as HIGH level, in the data codes is limited to T.sub.max, e.g., to 14T, in which T is a unit length representing one binary code, and the minimum length of a continuous binary codes of one level, such as HIGH level, in the data codes is limited to T.sub.min, 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 a continuous binary codes of one level, such as HIGH level, with a predetermined length 16T which is 2T greater than T.sub.max. An inserter inserts the synchronization code intermittently in the sequential data codes.
