Wide Screen Signalling
Similarly the ARC-10MC can also use wide screen signalling to determine the aspect
ratio of the input video. Again the ARC-10MC will convert or bypass depending on the
various selections. WSS information as with video index can be placed on the output
video.
Note:
WSS and Video Index controls are completely independent. This will allow insertion of both
types of data onto the video output. Should WSS and Video indexing both be present on the
input video preference will be given to Video indexing.
Gains and Offsets
RGB picture level controls gain and dc offset allows control of the video image
brightness, contrast and colour.
ARC-10MC Gain and Offset menu
The required value may be typed directly into the numeric display or if the cursor is
placed over the slider left clicking with the mouse will cause the slider bar to jump
directly to that value.
The gains and offset levels can be returned to zero at any time by pressing the CAL button
under each slider.
Picture Crop
The Crop tab gives access to the picture crop options along with the closed caption and
wide screen signalling controls. These controls act to crop the input video so their action
will be affected by the aspect ratio selection. Up to 31 lines of vertical crop both top and
bottom are available and up to 31 pixels horizontally both left and right. Adjust the
appropriate slider control to crop the top, bottom, left side and right side of the picture.
Pressing the cal button under each slide control will return that slider to 0 (no crop).
When an aspect ratio is selected which results in a vertical shortening of the picture any
NTSC closed caption information would become visible and any horizontal scaling would
corrupt this information.
