Introduction
The Vela CineCast™ Quad Pro decoder, Model 2000-0422, is an MPEG-2 audio/
video 4-channel decoding system designed for a wide range of video applications
requiring Serial Digital Interface (SDI) video output. The decoder is designed to
handle compressed digital video resolutions ranging from MPEG-1 SIF (352×240
pixels) to MPEG-2 digital D-1 4:2:2 video (720×512 pixels). The decoder is
designed to be conveniently mounted in a standard 19-inch equipment rack, occu-
pying one unit of rack space. The Quad Pro supports Ultra-2 Fast-40 LVDS SCSI,
compatible with single-ended SCSI. The Quad Pro runs under the Microsoft
®
Windows
®
2000 or Windows NT™ 4.0 operating systems.
An enhanced version of the Quad Pro, the Model 2000-0422-1 (“Dash-1”), includes
all the features of the Model 2000-0422 and incorporates several others:
• Video Fade: In addition to the audio fade/switch and video switch A/B
capabilities of the CineCast Quad Pro, this option provides the capability
for video fade from or to adjacent channels. Duration of the fade is pro-
grammable from 33 msec. up to 5 seconds. The capability to fade to a
background color between the channel-to-channel fade is also supported.
• Genlock Adjustment: The standard CineCast Quad Pro aligns the SDI output
with the genlock input. The “Enhanced” Dash-1 version provides the capa-
bility of adjusting the SDI output with respect to the genlock reference. The
Model 2000-0422-2 version of the Quad Pro also supports this same SDI
genlock reference adjustment feature.
• Enhanced secondary audio decoder supports MPEG-2 AAC audio.
All versions of the Quad Pro decoder will be referred to in this book as the Quad
Pro. Features, commands, etc., unique to the “Dash-1” and/or Model 2000-0422-2
will be mentioned and amplified upon as required.
Developer tools for the decoders include a comprehensive 32-bit Windows SDK
for application development, a sample MPEG player application and a selection
of sample MPEG-2 clips.
