PLANET ICA-H312 - Manual (Page 55)

3.8.2 H264 Profile
It’s H.264 encoder mode in this profile.
Resolution: There are four resolutions in this profile: 4CIF, CIF and QCIIF.
Rate Control: Defines the rate control method of this profile. There are two options:
Constant Bit Rate (CBR) or Variable Bit Rate (VBR). For CBR, the
video bit rate is between low to high bandwidth based on different
resolutions. User can set the desired bit rate to match the limitation
of bandwidth. For VBR, user should choose the quality level to set
the video quality rather than bit rate. The quality level is between 1
and 100. The higher value can reach the better quality but of course
will consume higher bandwidth.
Max Frame Rate: Defines the targeted frame rate of this profile. For example, set the
frame rate to 15 fps, then the image will be updated for 15 frames
per second. User can set the desired max frame rate versus video
quality under the limited bandwidth.
GOP Control: Defines the Intra/Inter-frame (I/P) ratio of this profile. For example,
set the GOP to 30, then the video stream will have one Intra-frame
every 30 frames.
