6Turn the left knob (OPhas�) to adjust the phase. (�8 to +8)
For a composite analog signal, it is also possible to adjust the
subcarrier phase using the center knob (OSC�). (�100 to +100)
7To input a video signal with an H shift for color framing
correction, press F8 (H SHIFT) to make the setting.
Off: No H shift.
Left: Shift the horizontal phase of the video input left by
140 ns to carry out color framing correction.
Right: Shift the horizontal phase of the video input right by
140 ns to carry out color framing correction.
The setting of F8 is stored independently for each input button
number.
D2 VTR color framing correction
In an editing system using D2 VTRs, if a section of video which
has passed through the DME is joined to a section which has not
passed through the DME in a single scene, at the cut point there
may be a dislocation in the horizontal phase. This occurs because
the signal from the playback D2 VTR which has passed through
the DME is still subject to a horizontal shift to correct the color
framing. The reason for carrying out the horizontal shift on the
playback VTR is as follows.
Because of the one frame delay for passing through the DME, the
edit IN point is advanced one frame on the playback D2 VTR. As
a result, there is a phase difference in the color framing between
the reference signal subcarrier and the playback signal subcarrier.
To correct for this phase difference, the image is output from the
playback VTR with a horizontal shift (H shift processing).
