Eco4

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.

MPEG Quality 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.
