An SDDI signal in accordance with an AV signal is selectively recorded in an MO disc 6 of a portable AV editing apparatus 1 from a hybrid recorder 20 provided with an on-line editing function. The user carries the portable AV editing apparatus 1 around separate from the hybrid recorder 20 and uses the SDDI signal recorded in the MO disc 6 to perform off-line editing and prepare an EDL (edit decision list). This EDL is transmitted from the field to the station. The EDL is used for on-line editing at the station.
