摘要 |
A DVD recorder is provided which includes an NTSC decoder (15) for converting an NTSC-based TV signal into an ITU-R BT. 601-based video signal, an MPEG encoder (17) for encoding the ITU-R BT. 601-based video signal into an MPEG-2 data stream, a driver (23) for recording the MPEG-2-based data stream to a DVD disk, and a VBI slice circuit (24) 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 (17) 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.
