1.4 CONNECTION FACILITIES
1.4.1 INPUTS
The switcher exclusively disposes of serial digital video inputs which, depending
on the application, can be used without restrictions, either as background, key or
fill signal in all mixing levels (including the downstream keyer).
As a standard feature of the switcher, 12 (DD5), 16 (DD10), 24 (DD20) and 32
(DD30) inputs are provided.
The inputs are internally terminated and can process video signals in the format 4:3
or 16:9 (270 Mbits/s) in the standards 525/60 2:1 or 625/50 2:1 (no mixed forms).
All inputs are provided with an equalizer for compensating cable lengths of max.
150 m.
Furthermore, all inputs are provided with an automatic delay time correction which
can compensate delay inequalities referred to the blackburst input in the range of
±
1/4 line.
Asynchronous signals or inputs not connected, are detected and indicated.
For synchronization of the switcher in the studio, a loop-through reference input for
an analog blackburst signal is provided.
1.4.2 MATTE GENERATORS
For background designing, 2 central matte generators are provided in the switch-
ers DD20 and DD30, which can be optionally used as background, key or fill signal.
For the types DD5 and DD10, only one central matte is available.
As a standard feature, in addition to plain mattes, extremely soft color floating ef-
fects between two optional colors or black or white are possible in H or V direction
or diagonally. Position and angle of the diagonal can be varied in steps of 2 de-
grees.
Alternatively, color or brightness floating can be determined by the signal from a
wipe generator of mixing level ME1.
Optionally, a memory can be assigned to the matte generators, which stores wipe
or key signals, thus enabling complex color and brightness floating effects.
