ABSTRACT:
A "universal" system records or transmits both 24 fps (or 25 fps) motion picture film sources and non-film interlaced or progressively-scanned video sources, employing any one of several international television standards (e.g., NTSC, PAL, HDTV/ATV, etc.) as progressively-scanned video at a nominal frame rate of 24 or 25 frames per second (i.e., 24 Hz or 25 Hz). When the source is interlaced video, a real-time motion signal, independent of motionless vertical transitions between the temporally displaced fields in the interlaced television signal, is recorded or transmitted along with the progressively-scanned video data. Use of a real-time motion signal in reproducing video derived from an interlaced television signal source results in a reproduced interlaced television signal (whether a conventional NTSC or PAL reproduction or an enhanced reproduction) substantially free of interlace errors, despite the conversion to and from progressive scanning, or, alternatively, a reproduced frame-multiplied progressively-scanned television signal substantially free of motion artifacts, despite the conversion to progressive scanning and the subsequent multiplication of frame rate.
