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
