iStream
This is a groundbreaking technology that helps saving network bandwidth efficiently whilst
maintaining the crystal image quality for critical image details based on the 2 cutting-edge features as
follows:
Figure: iStream Settings
EcoZone
As opposed to iZone, the newly introduced “EcoZone” can swiftly
identify dynamic motions occurred
within a scene and retain its details with clear quality, whereas the rest areas, e.g. static background,
will be imposed on higher compression level, thus economically decreasing bandwidth on less
important things and still keeping the dynamic motions details for future forensic purpose. The
intensity for EcoZone can be defined by the “Level” dropdown menu.
EcoFrame
By enabling the proprietary EcoFrame function, the overall bitrate, i.e. bandwidth utilization, will be
reduced even further. When less motion happens within a scene, e.g. storeroom, I-frame number,
which is needed when motions are in scene, will be cut down largely by EcoFrame activation. Based
on divergent complexity of scenes and motions occurred, a large amount of bandwidth saving can be
achieved to render a compact yet valuable performance on bandwidth utilization. Note that it is
compulsory to enable both EcoZone & EcoFrame functions simultaneously by selecting the option
“E EcoFrame” since Eco
Frame is per se an enhancing technology that is based on EcoZone
to promote the overall efficiency by a large scale. The intensity for E EcoFrame can be
defined by the “Level” dropdown menu as well.
Note
Due to the attribute of dynamic
bitrate management, “Rate Control” options (CBR,
CVBR, and VBR) under Encode page will NOT
be available when “EcoZone” function
is activated.
Due to the dynamic frame & bitrate adjustments, both “Rate Control” & “GOP” options
under Encode page will NOT be
available when “E EcoFrame” function is
enabled.
