Video Format The format can be configured to be NTSC (30fps), PAL (25fps) or
PAL-M (30fps). (The PAL-M feature is supported on models ending
in xxx1 or higher.) PAL-M is a video format standard used in Brazil.
The main difference between PAL and PAL-M is a lower resolution
(525 lines versus 625) and a higher frame count (30 frames per second
at 60 Hz versus 25 frames per second at 50 Hz).
Video Aspect Ratio Aspect ratio is the ratio of the width of the image to the height of the
image. Standard TV images generally use an aspect ratio of 4:3; DVD
players and some camera can produce 16:9. Set this value to match the
video input source, either 4:3 or 16:9.
Video Input Type The input can be changed to accept either S-Video or composite
(BNC). Note: VBSSM models do not support S-Video.
Video Source This enables the user to select the bandwidth for tracking the video
input.
• Normal – Select for stable sources such as SDTV, DVD or
camera.
• High Jitter – Select for unstable sources such as VCR or VTR.
