Digital recording and reproducing apparatus which multiplexes and records HDTV, SDTV and trick play data together on a magnetic tape |
摘要 |
A digitally recording and reproducing apparatus simultaneously records two kinds of digital signals of an identical video program, generated by high-efficiency coding, or a relatively high bit-rate signal and a relatively low bit-rate signal, onto the approximately the same positions on the tape. The apparatus is constructed so that the low bit-rate signal is commonly used for normal playback and search-playback. Further, the recording time can be lengthened by reducing the recording bit-rate.
