VIDEO VERTICAL BLANKING DATA
VBI Data Pass-thru When using 4:2:2 chroma sampling, compression is supported
down to lines 10 (NTSC) and 7 (PAL) on each composite
video field.
VBI Data Re-insertion • EIA-608 Line 21 data for both fields (CC & XDS) per
ATSC (Annex A, A/53B). Also compatible with Harmonic
and Tandberg proprietary protocols;
• Type I and II Nielsen AMOL compatible with Tandberg
proprietary protocols.
VBI Data Re-insertion Control Wegener COMPEL control may enable/disable any or all of
the above re-inserted VBI lines
AUDIO DECODERS (MAIN) Two independent audio decompression devices (ports 1&2)
Compressed modes MPEG-1 Layers 1 and 2, MPEG-2 Layer 2
Compressed data rates MPEG: Up to 384 kbps ES rate
Uncompressed mode Full-rate (AES3) digital audio per SMPTE302M, 2 channels
per stream, 24-bit subframes, 48 kHz sampling
Sample Rates Supported 32, 44.1, and 48 kHz. Both Audio port 1 and port 2 must be
assigned audio streams with same sample rate. If one is
SMPTE302M audio, this rate is fixed at 48 kHz per above.
Stereo output routes Normal stereo, Sum to both, L to both, and R to both
