Abstract: A signal processing method and apparatus wherein digital image data is compressed, recorded, and edited and where multiple playback/record cycles do not degrade the quality of the image. Digital image signals are compressed and recorded by a digital VTR. The recorded signals are then played back and the resulting signal is decompressed along one data path or inserted into a standard video interface format signal along a second data path. The compressed image signal in the standard video format may then be edited as if it were a standard video signal. The compressed video signal is then extracted from the standard interface signal and rerecorded. The compressed signal can be edited without decompression and recompression, thus maintaining the quality of the image data.
