Introduction
9084 Functional Description
9084 Functional Description
Figure 1-1 shows a functional block diagram of the 9084. The 9084 provides
HD/SD-SDI RGB color correction with frame synchronization that supports
all popular SD and HD video formats including 525i, 625i, 720p, 720f, 1080i,
1080p, and 1080psF. Input video format is auto-detected by the card. The
9084 accepts either an HD SDI input (1.485 Gbit) or an SD SDI input (270
Mbit) and automatically equalizes for cable loss. The 9084 also provides
processing-bypassed reclocked SDI outputs.
Processed video is synchronized to either a frame-wide reference or a local
reference. For further flexibility in resolving system timing problems,
additional fixed delay can be added to the video. Ancillary Data (VANC) is
protected, and is passed from input to output ensuring data is not lost during
the frame sync operation.
9084 Input/Outputs
The 9084 provides the following video inputs and outputs:
• Inputs:
• HD/SD-SDI IN – dual-rate HD/SD-SDI input
• Outputs:
• HD/SD-SDI OUT – four dual-rate HD/SD-SDI buffered video
outputs
•
RCK OUT – four dual-rate HD/SD-SDI reclocked buffered video
outputs
