1.1 Product description
The Flashlink PGM-HD-2X1-PB is a 2x1 HD/SD program switch with configurable fade-
in/fade-out and built-in frame synchronizer. Embedded audio is faded in/out with the
video. The frame synchronizer locks an HD-SDI or SD-SDI input to a black & burst or
tri-level signal, and a de-glitcher ensures an always error-free output.
The user parameters of the card can either be changed by switches on the board, or by
the control interface Gyda.
