AVoption Hardware Overview
AVoption hardware consists of two cards: an
Avid Broadcast Video Board (ABVB), and a Janus
Advanced JPEG Compression card. These cards
connect with a ribbon cable. The ABVB breakout
cable is also included.
AVoption Hardware
Capabilities
AVoption hardware:
• Receives composite or component video sig-
nal.
• Digitizes incoming video.
• Compresses digitized video using advanced
JPEG compression.
• Outputs composite and component video sig-
nals.
• Connects to a second VGA monitor (optional)
for displaying the Movie window.
Avid Video Resolutions (AVR)
The ABVB captures and plays back video media
with JPEG compression technology, expressed
as Avid Video Resolution (AVR) levels, in the
MSM media format (Media Composer 7.x com-
patible). AVoption can import both MSM video
and MFM video, which is generated by AudioVi-
sion 4.x and Media Composer 6.x.
AVR levels dictate the amount of JPEG compres-
sion, which determines image quality and stor-
age requirements for digitized video.
The following resolutions are available:
• Single-field – AVR 2s, AVR 3s, AVR 4s, AVR 6s,
AVR 8s, AVR 9s
• Two-field – AVR 12, AVR 70, AVR 70B,
AVR 71, AVR 75, AVR 75B, AVR 77
Lower numbered AVR levels require less hard
drive space, but provide lower resolution than
higher numbered AVR levels.
The lowest resolution is AVR 2m. The maxi-
mum resolution is AVR 77 and is considered to
be broadcast quality.
