ABSTRACT:
A signal conversion recording method applies a signal recording method whereby a video signal converted to a frame rate greater than the frame rate of the signal source by repeating particular fields plural times is converted to an intermediate signal having a frame rate substantially equal to the frame rate of the original signal source by deleting these repeated redundant fields. This intermediate signal is compression coded to obtain the recording signal, and the recording signal is recorded to a recording medium together with a repeat first field flag RFF declaring whether a field was deleted, and a top field first flag TFF declaring which of the two fields in the each of the resulting frames is first on the time-base, is wherein when plural logical recording periods are provided on a single recording medium, the video signal is converted to the recording signal so that the flags hold particular values at the start and end of each recording period.
