ABSTRACT:
Apparatus for deriving from a motion picture film for transfer to a video recording medium a video signal having increased vertical resolution for display using progressive scanning. In the apparatus, a deriving system derives the video signal from the motion picture film; a flag signal generating circuit generates a flag signal indicating that the video signal is for display using progressive scanning; and a recording system records the video signal and the flag signal in the recording medium. In a method of deriving from an interlaced high-definition video signal an interlaced standard-definition video signal having increased vertical resolution, the interlaced high-definition video signal is converted into a progressive high-definition video signal. The number of pixels in the progressive high-definition video signal is reduced to provide a progressive standard-definition video signal, which is converted into the interlaced standard-definition video signal. An apparatus for reproducing a video signal recorded on a recording medium includes a system for reproducing the video signal from the recording medium, and a circuit for extracting from the reproduced video signal a flag signal indicating a display scanning mode for the video signal. A display apparatus includes a circuit for receiving a flag signal indicating a display scanning mode for the video signal, and for generating a control signal; and a circuit, responsive to the control signal, for displaying the video signal in the display scanning mode.
