[Video Signal Type]
Auto detect signal type on booting:
Automatically detects the type of video input is
NTSC or PAL.
The supported codecs vary from model to model.

[Bandwidth Management]
When using MPEG-4 or H.264, it is possible to control the bitrate, which in turn allows the
amount of bandwidth usage to be controlled.
VBR (Variable Bitrate):
The quality of the video stream is kept as constant as
possible at the cost of a varying bitrate. The bandwidth is much more efficiently used
than a comparable CBR.
Set the image quality to one of the 3 standards:
Fair
,
Good
, and
Excellent
.
CBR (Constant Bitrate):
CBR is used to achieve a specific bitrate by varying the
quality of the stream. The bitrates available for selection depend on the image
resolution.
