Abstract
A video signal is supplied from a digital VTR 1 and is encoded by an MPEG encoder 8. The encoded video signal is recorded as a compressed video signal in an HDD 9. A plurality of compressed video signals are recorded in the HDD 9 and addresses of the compressed video signals are stored in a controller 6. MPEG decoders 12 and 14 decode the compressed video signals which are read out from the HDD 9. After a video signal processing apparatus 3 executes an editing process on the decoded video signals, a synthesized video signal is supplied to a digital VTR 10 through a switch 7. The synthesized video signal recorded in the digital VTR 10 is supplied to the video signal processing apparatus 3 for further processing through a switch 13 without being decoded. When an end of the editing processes is detected from an input apparatus 5, the synthesized video signal is supplied from the video signal processing apparatus 3 to the HDD 9 through the switch 7 and MPEG encoder 8 and is held as a compressed synthesized video signal.
