A system for manipulation of isochonous data provides for definition of frames within the string of isochronous data, if necessary, and then allows selection of frames of data from items of isochronous data to define segments therein. retrieve, copy and delete operations are facilitated by the use of the frames of data as arguments in the presentation of commands to an operator. Criteria such as time and frame numbers and names may be used to define segments and express Boolean logic operations to be carried out during these operations and to define, during editing, of the particular frames to be reproduced. By doing so, only the frames of interest are retrieved from or copied to memory to reduce memory operation and data transmission overhead.
