摘要
A television receiver receives HDTV video signals and scan converts them to a lower line scanning rate with field-to-field interlace. This scan conversion is done to conserve the power consumption by the magnetic deflection system for the kinescope, which has a display screen with a 16:9 aspect ratio and a dot pitch for displaying a 480 scan line frame. The receiver receives scan converts NTSC video signals using time compression circuitry to present them in variants of letter-box form in which the images fill the full height of the display screen, but not its full width.
