84 Appendix: GEME-VM3000 Series Introduction
Optional scaling: Scaling of acquired image or portions of an
image is available as follows:
X Adjustment of hue (for NTSC signals), contrast (0 to 200%),
brightness, and saturation (0 to 200% for U and V signals).
X Automatic chrominance gain control.
MPEG4 Encoding
MPEG4 video encoding: Video encoding quality level can be set
as follows:
Supports setting of initial motion detection area and assignment or
creation of directory for saved files.
Save video file: A continuous video can be saved to either M4V or
AVI video file format. Users may play AVI files with MS Media
Player after installing the XVID CODEC (see ADLINK All-in-One
CD).
Save single image file: Individual images can be saved to either
BMP or JPEG image file format.
MPEG4 Decoding
MPEG4 video decoding: Video decoding can be assigned a
source from the local memory buffer, file access, or TCP/IP port.
The quality of decoded video can be used to adjust the video
encoding level. Decoding quality can also be used to control the
flow rate between encoder and decoder and to adjust motion
detection settings.
Save video file: A continuous video can be saved to either M4V or
AVI video file format. Users may play AVI files with MS Media
