The HD/SD SDI (serial digital interface) 16-channel de-embedder card is able
to de-embed eight or 16 audio channels from SDI-SD as well as from SDI-
HD video streams. For the D21m I/O system it acts as an eight-or 16-channel
audio input card. These two modes are determined by hardware switches
located on the card.
The SDI standard defi nes up to 16 audio channels transmitted within a video
signal. These 16 channels are divided into four groups of four each. The user
can determine by hardware switches whether all four groups, or only groups
1+2, or only groups 3+4 will be de-embedded.
The card hosts SFCs (sampling frequency converters) that are bypassed per
default. When bypassed, the SDI card is fully compatible to receiving embed-
ded Dolby
®
E audio data. The SFCs can be enabled in case the audio extracted
from the SDI stream is not in sync with the local system. This means that the
mixing console can run fully independent of the video sync used for SDI.
This card works at a sampling frequency of 48 kHz only
.
