Configuration & Operation Guide

Live Trans
The unit transmits live images using JPEG or MPEG formats.
The NetVu Connected remote viewing software will use the settings configured on this page as the
defaults for JPEG & MPEG; High, Medium and Low settings.
High LAN/Medium WAN/Low VLBR This shows the transmission settings configured for a High quality LAN
(Local Area Network) connection, Medium quality WAN (Wide Area Network)
connection or a Low quality VLBR (Very Low Bit Rate connection).
Comp
Settings can be established for JPEG and MPEG compression.
Res
For MPEG and JPEG transmission, select image resolution settings (4CIF,
2CIF, CIF or QCIF).
Size_rate
For JPEG, the figure entered will be the size of the JPEG transmitted (in
Kbytes). For MPEG4 the figure will be the bit rate allocated. A higher rate will
provide better quality picture display. JPEG file sizes can be configured in the
range of 5-45Kbytes and MPEG bit rates in the range of 45-2500Kbits/second.
PPS
This shows the number of pictures transmitted per second. For JPEG, the actual
images transmitted will depend on the bandwith of the link, increasing the
pictures sent per millisecond may introduce time lag if bandwith is not sufficient.
On MPEG transmission, increasing the pictures sent will also reduce the quality
of the images (as more images are transmitted for the defined bit rate).
MPEG Type
Select whether transmitted MPEG4 images are sent as RAW data or in GOV (Group
of Video) format. RAW mode transmits a single I frame and then a sequence of
P frames (until a change in transmission is detected). GOV mode sends I and P
frames in a standard format i.e. I to P frame ratio as set by the I Frame Ration option.
