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 & Quality 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.
The Quality of the MPEG data transmission can be set from CBR
(Constant Bit Rate) to High 32. A higher quality setting may result
in a lower transfer speed.
I Frame Ratio Select the ration of I Frames recorded between each P Frame.
Note: An MPEG I-frame is considerably larger than a P-frame. Therefore the higher the IP ratio,
the higher the disk space required to store recorded images.
