Serial Digital Video Matrix Module
Input Standards
The router is capable of handling up to four different input standards
(143Mbs, 177Mbs, 270Mbs, and 360Mbs) depending on which SIMMs are
installed. Current SIMMs (Quartz PCB) are capable of 270Mbs operation
only. Multi-standard SIMMs are under development. Each input can be set
to any of these standards which are programmed into the setup of the
system, either at the factory or from a PC using the configuration program.
TV Line Switching
Sometimes it is important to change the TV line in the vertical blanking
interval during which the routing switcher makes its crosspoint switches.
Any line from 7/320 to 11/324 may be selected using the three jumper links
LK6, 7, 8. The diagram on the circuit board shows the positions of the
jumper links.
It is also possible to choose whether to permit switching on every TV field
or only on the first field of each picture. This can be important in certain
editing applications.
The factory settings for NTSC are line 10/273 and every field. For Pal they
are line 7/320 and every field.
