Keyer Carrier Module (064804)
There are two Keyer Carrier Modules for each M/E and two for the DSK. The
Keyer Carrier Module accepts serial video signals and keys from the Crosspoint
Module and parallel keys and shaped video from the Chroma Keyer Module for
that M/E. The outputs are shaped video and clipped and gained keys. Outputs are
sent to the Mixer Interface Modules.
The Keyer Carrier Module does the following:
■
Converts video from serial to parallel (not used with chroma key)
■
Interfaces to the optional BORDERLINE Mezzanines (key layer only)
■
Bypasses BORDERLINE submodule if not installed
■
Interfaces to the Key Processor Mezzanines
■
Can do a non additive mix with the other Keyer Module in that M/E
■
Routes wipe and wash information from the Mix/Wipe Module to the Key
Processor Mezzanine Board
■
Generates Box Mask for the Keyer Mezzanine Boards
■
Transfers key and video fill information from Chroma Keyer Module to Keyer
Mezzanine Board
Each Keyer Carrier Module has connectors and circuitry to support two Keyer
Mezzanine Boards and one BORDERLINE Mezzanine. The input signals for each
Keyer Carrier Module are the following:
