Introduction
9064 Functional Description
9064 Functional Description
Figure 1-1 shows a functional block diagram of the 9064. The 9064 up/down/
cross-format converter also includes an RGB color corrector and a full video
frame synchronizer. The 9064 also handles AFD code detection/ insertion and
processing, timecode support, and closed captioning support. Aspect ratio can
be corrected to provide proper output aspect.
Note: Some of the functions described below are available only when using the
DashBoard™, or Cobalt
® OGCP-9000 or OGCP-9000/CC Control Panels
user interfaces. Refer to User Control Interface (p. 1-12) for user interface
descriptions.
9064 Input/Output Formats
The 9064 provides the following inputs and outputs:
• Inputs:
•
HD/SD SDI IN – dual-rate HD/SD-SDI input
• Outputs:
• SDI OUT – four SD-SDI buffered video outputs
• RCK OUT – four SD-SDI reclocked buffered video outputs
Video Processor Description
The 9064 features a scaler that provides up, down, and cross-conversion using
de-interlacing and motion adaptation for high quality up-conversions. The
scaler also provides user-adjustable aspect ratio control and zoom control.
Separate controls are provided for SD and HD inputs that allow the card to
flexibly and independently handle mixed input formats.
The 9064 video subsystem also provides the functions described below.
Video Processor
The 9064 provides full color processing control (luma gain and lift, chroma
saturation, and color phase) of the output video. The 9064 video processor
also provides white, black, and chroma clip control. Clipping can be applied
with either a hard or soft white clip and also a chroma saturation clip. Luma
and chroma gain controls can be ganged to provide adjustment for both gain
controls.
