Product overview
The Flashlink ARC-SD-DMUX converts the aspect ratio of a SD-SDI signal. The module
changes the scaling during the vertical blanking period so that the changes are apparently
instantaneous.
Two SDI outputs and a set of configurable analog video outputs are provided.
The ARC-SD-DMUX is also a frame synchronizer with an adjustable offset relative to the
sync signal.
The ARC-SD-DMUX also has a de-glitcher to give error-free synchronous switching.
The audio embedded in the SD-SDI stream is de-embedded and can be delayed relative to
video. The stereo audio channels can be swapped in the audio matrix before they are re-
embedded in the SD-SDI data output stream.
A selection of user parameters of the card can be controlled by switches on the board.
Complete control of all parameters is available by use of the Flashlink RS422 Control
Protocol Version 4, which is supported by the Multicon GYDA system controller from
software release 2.13.
