SD Range
Transmission
The NetVu Connected remote viewing software (NetVu ObserVer) will use the settings configured
on this page as the defaults for JPEG & MPEG; High, Medium and Low settings. The SD transmits
live images using JPEG or MPEG image formats utilising the soft codec architecture (VISP). The
SD features Trans Coding which enables recorded JPEG images to be Transcoded to low bit rate
MPEG4 for transmission over limited bandwith links. This is essential for efficient, ‘fast update’
remote viewing of recorded video in central monitoring applications. The SD can also Transcode
from recorded high bit rate MPEG4 to low bit rate MPEG4.
JPEG/ MPEG4 Quality This shows the remote viewing settings being configured. These
will be used by the remote viewing client as default settings.
Display Res There are four display resolutions available; 704x512, 704x256,
352x256 & 176x128
Size KB In the JPEG settings, the figure entered in this text box will be the
size of JPEG transmitted (in Kbytes). In the MPEG4 settings, the
figure will be the bit rate allocated. A higher bit rate will include
more detail, but will take up more bandwidth on remote viewing,
or more storage space on a hard drive.
PPS This shows the pictures per second that will be transmitted. On
JPEG, the actual images per second transmitted will depend on
the bandwith of the link, increasing the PPS may introduce time
lag if bandwith is not sufficient. On MPEG transmission increasing
the PPS will also reduce the quality of the images, as more
images are transmitted for the defined bit rate.
