46 Glossary
Figure B
Strobe numbers are used to introduce a third dimension into matrix space. Every routing switcher
in a switching system is assigned to a strobe. In systems using more than one strobe (and,
therefore having three-dimensional matrix space), crosspoint coordinates are given in the form
(input,output) on strobe x. In Figure C, the coordinates of the indicated crosspoint in the left
routing switcher are (4,2) on strobe 1. The coordinates of the crosspoint on the right are (4,2) on
strobe 2.
Figure C
NTSC
National Television Standards Committee. The NTSC is responsible for setting television and
video standards in the United States (in Europe and the rest of the world, the dominant television
standards are PAL and SECAM). The NTSC standard for television defines a composite video
signal with a refresh rate of 60 half-frames (interlaced) per second. Each frame contains 525 lines
and can contain 16 million different colors.
