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.
