5.2 VSETUP.EXE
VSETUP.EXE is run from the command line and is used to modify the video and compression parameters
of the 512. Once modified, the parameters will remain in effect, even through power cycling, until they
are changed again by VSETUP.EXE. Parameters can be modified at any time and take effect when
X12TSR.EXE is loaded or when an application starts the encode or decoder. VSETUP.EXE has the
following command line syntax.
C:\path>VSETUP [-1/-2][-B][-NTSC][-PAL][-Rxx][-Wxxx][-Hxxx][-M1][-M2][-VON][-VOFF][-Z][-Q]
Command line switches:
-1/-2 selects 512 board for which the parameters are to be modified. I.e. 1 (default) or
2.
-NTSC/-PAL selects the video system used. I.e. NTSC or PAL. Default: NTSC
-Gxx sets number of video frames in a MPEG GOP. Valid numbers are 3, 6, 9, 12,
or 15. Default: 15
-Rxx sets the desired compression bit rate in millions of bits per second (Mbps).
i.e. -R12 for 12Mbps, -R0.5 for 0.5Mbps, etc. Default: 4 Mbps
-VON/-VOFF -VON enable variable bit rate compression, -VOFF enables constant bit rate
compression. Default: VOFF
The following switches set the compression system as well as the capture resolution.
(Default: P0)
-P0 MPEG-2 compression, Size D1: NTSC - 704x480, PAL - 704x576 pixels
-P1 MPEG-2 compression, Size 1/2 D1: NTSC - 352x480, PAL - 352x576 pixels
-P2 MPEG-2 compression, Size 2/3 D1: NTSC - 480x480, PAL - 480x576 pixels
-P3 MPEG-1 compression, Size CIF: NTSC - 352x240, PAL - 352x288 pixels
-M1 same as -P3
-M2 same as -P0
-Z loads default values for all parameters.
-Q quiet mode.
NOTE: Using VSETUP with no switches displays the current settings as well as a list of available
switches.
