- No, they (NBC and the host country's RTU) are using special slow motion
- equipment for basketball, swimming, diving, track & field and gymnastics.
- One system is made by Sony (used at the winter Olympics) and a new one by
- Panasonic. Panasonic is using an AQ-1000E camera, which operates at three
- times normal speed, and a modified AU-1000 M-II VTR to record the video.
- The camera uses digital signal processing and the tape can be played in any
- M-II VTR. NBC will have two of these systems, which will be moved to
- various venues.
-
- The Sony system uses the BVP-9000 CCD camera and the BVW-9000 Betacam SP
- VTR. Again, three times normal frame rate is used.
-
- Hope this helps.
