1.5 MIXING STAGES

For background designing (BGND), a mixing stage (Mix, Add, Wipe with border)

is available for each mixing level (ME).

The mix and key stages are set up in a cascaded way and are provided with tap-

pings for coupling in and out signals for a DVE unit. Re-entry of the mixing levels

is possible.

The preset/program stage (PP) at the output of the switcher is identically designed

with regard to the mixing stage. Thus, for post-production purposes, a full mixing

level is available.

A separate channel is available for preview in the mixing levels, which is supplied

with equal input signals. Different control signals enable to preview the next con-

tribution (AUTO PREVIEW) or to make a transition without affecting the program

signal (TRANSITION PREVIEW).

1.5.1 INPUTS/OUTPUTS

As inputs, all video inputs, the signal of a preceding or succeeding mix/key stage,

the signal of a frame store and the central mattes are available for each mixing

stage.

Additionally, a wipe border matte generator for the border of the wipe generator is

provided for each mixing stage.

As outputs, program signal and preview signal are available to the user. In the pre-

set/program stage, a clean-feed output signal is additionally available, which can

be optionally tapped off after the preset/program stage or after the downstream

keyer.

1.5.2 AMPLITUDE MIX

Transition between two input signals (MIX) is possible by hard cut (CUT), automatic

fading (AUTO), automatic transition (EXTRA) or manually with the fader (FADE).

For transition, different fading characteristics (linear, gamma, etc.) are possible.

Transition via a black signal (BLACK PRESET) can also be performed.

For additive mixing (ADD), the output level can be more than 100% and is internally

limited.

1.5.3 PATTERN MIX (WIPE)

Pattern mix of two optional input signals is made with a control signal supplied by

the wipe generator.

Optionally, a second wipe generator (from DD10) can be inserted per mixing level

(example: WIPE in PATTERN KEY).

Additionally, the result of this manipulation can be provided with a border which can

be filled with a wipe border matte. A special signal of the wipe generator (Wiper-

Wash

), enables color wash effects of the border being coupled with the wipe pat-

tern.

The border can be switched into the video signal (CUT), the transparency (OPAC-

ITY) is selectable.

Switcher DD20/30 enables in conjunction with the mask store option to provide the

wipe border with a shadow.
