Product overview
Figure 1: Simplified block diagram of the FRS-HD-DMUX card
The Flashlink FRS-HD-DMUX synchronizes a HD-SDI or a SD-SDI input to a reference.
The reference can be a traditional black & burst signal or tri-level sync. The HD-SDI/SD-
SDI output can be adjusted relative to the sync signal. The FRS-HD-DMUX also has a
de-glitcher to give error-free synchronous switching.
FRS-HD-DMUX can be used as a frame delay. The adjustable delay is then relative to
the input SDI signal.
The audio embedded on the SDI is de-embedded and can be delayed relative to the
video. Each audio stereo pair can be swapped through a matrix before they are
embedded back to the SDI. It is also possible to disable the embedder function and keep
the SDI stream unaltered.
The user parameters of the card can either be changed by switches on the board, or by
the control interface GYDA.
