Abstract (en)

[origin: WO9924987A1] The user of portable MPEG based video equipment is able to produce an Edit Decision List (EDL) in the field. Using the EDL and a knowledge of the Group of Pictures (GOP) structure, a selection is made not only of the frames directly required in the EDL, but also the P and I frames relied upon for prediction purposes. By transmitting or storing only these selected frames, rather than the originally recorded MPEG material, considerable savings can be made. In the studio, the selected frames and EDL are used to provide the desired edited MPEG bitstream.
