Abstract
A DVD recorder is provided which includes an NTSC decoder () for converting an NTSC-based TV signal into an ITU-R BT. 601-based video signal, an MPEG encoder () for encoding the ITU-R BT. 601-based video signal into an MPEG-2 data stream, a driver () for recording the MPEG-2-based data stream to a DVD disk, and a VBI slice circuit () for detecting VBI from the TV signal. When the V timing of an input signal is asynchronous with that of recording signal, the MPEG encoder () inserts null data as blanking data into an arbitrary frame if a frame repeat has occurred or deletes null data from blanking data from an arbitrary frame if a frame skip has occurred.
