Proc Phase
This is Chroma (C channel) phase adjustment, expressed in degrees, ranging from
Decoder SD Input
Selects the input format for SD analog video. This must be changed to reflect the analog video format on the input for the 9033 to lock correctly. Valid SD formats are GBR, Component SMPTE, Component MII, Component Betacam, Component Y/C, and Composite.
SD Pedestal (Setup)
Selects between 0 IRE and 7.5 IRE of setup (pedestal)on the input analog SD signal. This tells the card how much setup needs to be removed from the input.

Frame Sync Enable
Enables the frame sync. If disabled the output video timing matches the input video timing.
Horizontal Offset
Allows the user to specify an additional horizontal offset between the output video and the frame sync reference in sample clock periods. These are sample clocks in the reference format, not the output video format. For example, if using SD black burst to time 720p59.94 video each sample clock is 37ns, not 13.5ns.
Vertical Offset
Allows the user to specify an additional vertical offset between the output video and the frame sync reference in lines. These are lines in the reference format, not the output video format.
Frame Latency
Specifies the smallest amount of latency allowed by the frame sync. This latency measurement is in frames of the output video. The frame sync will not output a frame unless the specified number of frames are captured in the buffer. Minimum latency is three lines and zero frames in all video modes. The maximum latency is format dependent. The operational latency of the frame sync is always between the specified minimum latency and minimum latency plus one frame (not one field).
Audio Delay
Specifies the amount of additional audio delay after matching video delay. When the change is under one and a half frames, the change in audio delay will be applied without interrupting audio. When changing audio delay more than a frame and a half at a time, there will be a slight audio glitch.
