Abstract
Data in the form of a sequence of data bits is compressed by separating the data into groups of data bits. A value is derived for the respective groups from the data contained therein. When a group has a derived value equal to the derived value of at least its adjacent group, a pre-assigned control code is used as compressed data. Such compressed data is representative of the data in consecutive groups of data having the same derived value.
