Abstract
The method and apparatus permits processing, for example, editing or synchronizing data sequences without using special marking devices and marking tracks for identifying preselected locations. For this purpose, a preselected partial data sequence is formed from a predetermined data sequence and serves as a reference partial data sequence. Such reference partial data sequence is utilized as a basis for comparison with further partial data sequences originating from the same or different data sequences for retrieving or identifying operations in connection with, for example, the joining, inserting or synchronizing of data sequences.
