Abstract: A method and apparatus for editing MPEG formatted image representative electrical signals provides a first decoder and storage for storing components of a first MPEG formatted stream of image data, a second decoder and storage for storing components of a second MPEG formatted stream of image data, and transition circuitry responsive to a transition position value, which designates where the transition is to begin, for generating an edited video stream which represents the transitioning from the first video sequence to the second video sequence. Different transition formats can be effected, including for example, an abrupt transition, a dissolve, or DVE.
