A method for converting an encoded digital video signal from a decoded relatively lower frame rate to a decoded relatively higher frame rate, including the following steps: deriving, from the encoded video signal, at the relatively lower frame rate, a decoded high resolution component and a decoded low resolution component; increasing the frame rate of the decoded low resolution component by interpolating successive frames of the decoded low resolution component; increasing the frame rate of the decoded high resolution component by duplicating frames of the decoded high resolution component; and obtaining an output relatively higher frame rate video signal by combining the increased frame rate low resolution component and the increased frame rate high resolution component.
