Three options exist for the sizes of the video display. You can
select between 176x120/176x144, 352x240/352x288, or 704x480/
401x576. The first value represents the PAL format of video and
the second value represents the NTSC format. In 704x480/401x576
mode, the frame rate will be reduced to 10fps and increased to
30fps automatically when it is switched back to a lower image
size.
Maximum frame rate:
This limits the maximal refresh frame rate, which can be combined
with the “Video quality control” to optimize the bandwidth utilization
and video quality. If the User wants to fix the bandwidth utilization
regardless of the video quality, choose “Fix bit rate” and select
the desired bandwidth.
Video codec type:
It can be either MJPEG or MPEG4. In MJPEG mode, the video
frames are independent. In MPEG4 mode, there are I frames and
P frames. To decode a P frame need the information of previous
frame. MPEG4 consumes much less network bandwidth than
MJPEG.
