At NHK, we have introduced Simultaneous Program Production using HDTV and NTSC, for public recordings of television musical programs at. NHK Hall. This enable us to produce (record or broadcast) in two different television standards efficiently, using an HDTV OB van system and an HDTV downconverting system. In 1992, we started this simultaneous production at NHK Hall as an addition to previous production facilities. A new OB van was also introduced to this system in August 1993, equipped with an HDTV digital video switcher. Through the operation of this system, we were able to mature our simultaneous production method, and we are recieving satisfactory results.
