From Wikipedia, the free encyclopedia

1 inch type B VTR (designated Type B by SMPTE) is an open-reel videotape format developed by Bosch, Bosch Fernseh Div., in Germany in 1976. It never saw much success compared to the competition type “C” format., due to the format requiring an optional and costly digital framestore in addition to the normal analog timebase corrector to do any slow motion (variable-speed playback), frame step play and later visible shuttle functions.

This was due to the fact that, unlike 1 inch type C which recorded one field per helical track on the tape, Type B segmented each field on 5 or 6 tracks per field according to whether it was a 525 NTSC or 625 PAL line machine.

The tape speed allowed 96 minutes on a large reel (later 120 min), and used 2 R/P heads on the drum rotating at 9000 RPM with a 190 degree wrap around a very small head drum, 52 video lines per head segment. Video is recorded on a FM signal with the range of 5.5 MHz. Three longitudinal audio tracks recorded: 2 audio and one Time code (LTC) track.

The picture quality was excellent and record only as well as standard R/P machines, digital frame store machines, reel-to-reel portable, random accesses cart machine and portable cart versions were marketed.

• RCA also sold the BCN50 as a HR-400.

• Ruxton Video in Burbank (1970-1980s) used modified BCNs for 24 Frame play back for TVs on Movie studio sets.

• Image Transform in Universal City used specially modified BCNs to record 24 frame also, but for their "Image Vision" system. The BCN would record and play back 24frame video at 10Mhz bandwidth twice NTSC resolution. To record this the head wheel and capstan ran at twice normal speed. Modified 24fps 10Mhz Bosch Fernseh KCK-40 cameras were used on the set. This was a custom pre HDTV video System. This recording could be film out on modified 3M Electron Beam Film Recorder-EBR. Image Transform had modified other gear for this process. At its peak this system was used to make "Monty Python Live at the Hollywood Bowl" in 1982. This was the first major DI digital intermediate post production using a Film recorder for Film out.

• Bell and Howell (later Rank Video Services) used special BCNs for mass VHS duplication. The BCN could play back movies at two times speed. That is the sync signals were also outputted at two times speed also! To playback this the head wheel and capstan ran at twice normal speed. Special VHS recorders could record this video. In doing this the duplication plant could output twice the product than the normal VTR system.

• Bell and Howell's Data Tape in Pasadena, Ca modified BCNs to record high speed data. These data records were mostly used my US government agencies. like NASA on the Space Shuttle. This unit could record up to 800 senors.
  • Because of the small scanner, BCNs could record even at high g-force. They could also record at low temp -40c. This was done at the Olympic Winter Games in Lake Placid (1980) and Sarajevo (1984).

• Some users modified BCNs to fit 2 hours rolls of tape on the BCN, so complete 2 hours movies could be on one roll of tape. The Factory later made this a factory option, BNC LP.

• The factory also sold SPL BCN. A BCN that moved the tape at half speed so that up to 4 hours could be recorded on reel. This was most used for tape delay.

• One of the first Digital SDTV VTRs was a beta, non production, BCN that could record and playback 601 digital signals. These two units paved the way for the later D1 (Sony) standard.
