Abstract

An original coded stream reproduced from a magnetic tape 1 is decoded by an MPEG decoder 29, and original video data of a base band is thus generated. A switching circuit 15 generates edited video data by switching the original video data and supplied insertion video data on the base band level at IN-point and OUT-point. The MPEG encoder 19 generates an edited coded stream by coding the edited video data supplied from the switching circuit 15. A system controller 13 controls a recording circuit 23 to record only a picture changed by editing processing, from among the edited coded stream, onto the magnetic tape.
