An apparatus for displaying a video image on a display system comprises a decoder for converting the video image into continuous fields arranged in a first sequence, the continuous fields having a first scan rate different from a second scan rate of the display system, and sending a first signal indicating the first scan rate, a system identifier for sending a second signal indicating the second scan rate, a controller in response to the first signal and the second signal for determining interrupt points for the continuous fields, the interrupt points dividing the continuous fields into odd-numbered sections of fields and even-numbered sections of fields, a buffer for storing the continuous fields, a reorganizing unit for reorganizing one of the odd-numbered or even-numbered sections of fields into reorganized sections of fields, and a multiplexing circuit for selecting the reorganized sections of fields from the reorganizing unit, and selecting the other of the odd-numbered or even-numbered sections of field
