GUIDE TO INSTALLATION AND OPERATION PRELIMINARY
14 | UVP-101i
4.3.7 Hue Adjustments (NTSC/525 only) [MENU: PROC
→
HUE]
The hue can be adjusted from –180 to +180 degrees in steps of 1 degree in 525 and 1.4 degrees in NTSC.
The default value is zero.
4.3.8 Horizontal Position (COMP IN only) [MENU: PROC
→
HPOS]
Picture position may be adjusted by +/- 7 pixels (a total range of 518 ns) in steps of ½ pixel (37 ns).
4.4 Timing Adjustments [MENU: TIMG]
When a valid external reference is present, the video output is phased with respect to the reference input
(frame sync mode). Otherwise, it is phased according to the video input (frame buffer mode). In this section,
we will assume that the analog composite output and the digital video output are phased together. Hence,
the term “output” refers to both the digital and the analog outputs. However, the digital output is slightly in
advance (~ 3 us) compared to the analog output.
4.4.1 Timing mode [MENU: TIMG
→
MODE]
When the studio reference and the analog composite inputs are asynchronous, and in order to time the
output video with the reference, the built-in frame synchronizer continuously changes the processing delay of
the video input with respect to the outputs. Due to this inherent operation, aligning re-encoded video data
with the same color frame as the input video is not always guaranteed. Misalignment results in encoding
artifacts at the composite outputs.
In order to overcome this drawback, the UVP-101i provides a special timing mode to reduce the encoding
artifacts derived from a color frame mismatch between the composite outputs and the decoded composite
input during genlock mode. Setting the timing mode menu to 4FLD reduces encoding artifacts. This
parameter is only available when a studio reference is installed and an NTSC composite signal is detected.
Frame phasing is not possible in 4FLD mode.
4.4.2 Frame phasing [MENU: TIMG
→
FRAM]
Frame phasing allows a super coarse adjustment in frame increments. In the user interface, this adjustment
is from 0 to 3 in steps of 1 frame. When a reference is present (frame sync mode), the frame adjustment
allows additional frames to be added after the frame sync. Frame phasing is not possible in 4FLD mode.
4.4.3 Vertical phasing [MENU: TIMG
→
VERT]
The vertical phasing allows coarse adjustments in line increments. In the user interface, this adjustment is
from 0 to 524 (or 624) in steps of 1 line. When the V phasing is zero (0) and the H phasing is zero (0), it
means the output is vertically and horizontally phased with the reference. When the reference is not present
and the UVP-101i is locked to the input, the minimum processing delay of the card is 3 lines. NOTE: vertical
phasing is not possible when there is no reference input, and the UVP-101i is in Satellite or VCR mode.
4.4.4 Horizontal phasing [MENU: TIMG
→
HORZ]
The horizontal phasing allows a less coarse adjustment in 37 ns increments. In the user interface, this
adjustment is from 0 to 63.6us (or 64.0 us). When the V phasing is zero (0) and the H phasing is zero (0), it
means the output is vertically and horizontally phased with the reference. When the reference is not present
and the UVP-101i is locked to the input, the minimum processing delay of the card is 3 lines. NOTE:
horizontal phasing is not possible when there is no reference input, and the UVP-101i is in Satellite or VCR
mode.
4.4.5 Horizontal Fine phasing [MENU: TIMG
→
FINE]
The horizontal fine phasing allows a fine adjustment in steps of 0.5 ns. In the user interface, this adjustment
is from –40 to +40 in steps of one (1). When the V, H and fine phasing are set to zero (0), the output is
