Model 1200 Features and Options
Model 1200 Features and Options
The Model 1200 Component Digital Production Switcher carries forward
the legacy of the industry-standard Model 100/110. Yet the Model 1200 is
a powerful advance over its analog predecessor, both because of many new
features and because of the tremendous advantage of digital video.
Features of the Model 1200 are listed on the following pages.
Inputs
■
Up to 16 optional component digital video or key inputs.
■
Inputs come in parallel or serial pairs and consist of submodules that
plug into the back of the frame and are secured by screws.
■
Autotiming automatically times each input for 525 or 625 line to match
an External Reference. There is no timing adjustment if inputs fall
within a range of ±24 µs (336 clocks).
■
Inputs may be custom-mapped to crosspoints using the menu system.
■
Inputs can be set for 8 or 10 bits, shaped or unshaped video, key, key
with depth, or the video input can be assigned to a key.
■
Processing amplifier can be adjusted and remembered for each
crosspoint column.
Effects System
■
Ten-bit component digital format for unparalleled signal quality and
virtually unlimited effects layering.
■
Ten Crosspoint Switching Buses: Program Background, Preset
Background, Key 1 Source and Fill, Key 2 Source and Fill, DSK Source
and Fill, Auxiliary 1, and Auxiliary 2.
■
Transitions include cut, lever arm, key out, fade to black. and frame-
accurate effects and downstream keyer auto transitions
■
Wipe/mask system includes patterns adjustable for H and V multiples,
position, aspect, matte edge color, width, softness, rotation, symmetry,
and modulation.
■ Many internal mattes: background matte, matte fill for each keyer,
matte for each Borderline mode, wipe edge matte, preset pattern edge
matte, and mattes generated by specific crosspoints when enabled
using the terminal.
■Program Mixer is standard. Preview Mixer is optional.

Section 1 Ñ System Overview
Keyers
■One effects keyer and one downstream keyer (DSK) standard. A
second effects keyer is optional.
■Each keyer is a self-contained submodule that mounts on the Keyer
Board. Keyers can be swapped for troubleshooting.
■Each keyer creates luminance, linear, and preset pattern keys from any
Key Bus input. Keys can be split (separate source and fill crosspoints).
■One Chroma Keyer option submodule mounts on the Crosspoint Board
and can be assigned to any of the three keyers. Can create a chroma key
from any Key Bus input and includes its own adjustable force box
mask.
■Effects backgrounds and keys can be transitioned on or off separately
or simultaneously.
■Separate DSK controls include cut, frame-accurate automatic mix, and
frame-accurate to black.
■Keys can be inverted and masked, and key layers can be adjusted for
layer opacity and edge softness.
■Selectable priority (which effects key layer appears over the other).
■Effects Send enables flying switcher luminance/linear keys, chroma
keys, and preset patterns over switcher backgrounds using an external
DPM. (Effects Send/Aux Output option required.)
■Z-Keyª Depth option submodule mounts on Program or Preview
Mixer Board and allows keying from Graphics Factory or Kaleidoscope
depth inputs. Depth is adjustable.
■Optional Borderline¨Key Edger submodule mounts on each keyer
submodule and adds borders, drop shadows, outlines, or extrusions to
key effects. Up to three options may be installed (one per keyer).
Interfacing
■A single interconnecting cable carries data between the frame and the
control panel.
■Ports may be programmed for various protocols, baud rates, etc.
■Contact-closure GPI interface includes 8 inputs for external triggering
of switcher operations and 8 outputs for switcher triggering of other
devices. GPI Outputs can be synchronized with switcher transitions.
All GPIs, inputs and outputs, are programmable to be activated from a
wide range of switcher events.
■Sixteen tally relay outputs corresponding to the 16 video/key inputs.
■Optional Satellite Auxiliary Bus Control Panel can be installed at a
remote location for remote control of Auxiliary Buses.
