With the new Panasonic WJ-GX900
MPEG2 encoder and the WJ-GXD900 MPEG2 decoder, a high-quality
video image monitoring system can be built by connecting camera
surveillance points and the control room.
With conventional wide-area/large image size surveillance systems,
the problem of increased image quality deterioration exists the
farther away the camera is located from the control room. The
Panasonic system compresses the camera image with a high-quality
MPEG2 image encoder and transmits the data to IPs, while a decoder
receives the data to be displayed on a monitor. This technology
ensures that the image quality will not be affected by
transmission distance, thus enabling image monitoring from
anywhere with a high quality image equivalent to that of TV
broadcasting.
There are two types of image transmission systems --the multicast
system and the unicast system--either of which can be selected and
configured according to the type of system or application
software.
