摘要
A method for coding an input video signal with a field rate of 60 Hz derived from a motion picture film source using 2-3 pulldown. In the method, duplicate fields are detected in the input video signal. Each duplicate field is eliminated from the input video signal to produce a progressive video signal comprising plural frames with a frame rate of 24 Hz. Finally, the progressive video signal is coded to produce a coded video signal. Preferably, when a duplicate field is detected in the input video signal, a control signal is generated in response to each detected duplicated field. Each control signal is then included in the coded video signal.
