A ½-In. Cassette HDTV VTR
For more than 63 min an HDTV baseband video signal and four digital audio signals can be recorded onto a newly introduced ½-in. metal particle (MP) tape cassette, which is slightly larger than a conventional home video system (VHS) cassette. Digital signal-processing techniques such as time compression, time expansion, digital filtering, and signal shuffling have been used in order to record a large amount of information onto the small cassette tape efficiently. A newly developed preamplifier integrated circuit (IC), preamplifiers within the rotating drum system, automatic equalization for the video system, and a new error-detection strategy for the pulse-code modulation (PCM) audio system make the performance of this VTR suitable for both industrial and professional use.
