MPEG4 Video Stream
Frame rate
Upon the real-time play, users should select a frame refresh rate per second. If the rate
is high, the image will become smooth. On the other hand, if the rate is low, the image
will not be natural but it can reduce a network load.
Bit-rate control
-Variable bit rate (VBR): It refers to the type of using a variable bit rate (VBR). Increase
a bit rate for the image with much motion, and decrease a bit rate for the image with
little motion. The basic setting value is a VBR type.
-Constant bit rate (CBR): Using a constant bit rate (CBR) may guarantee a stable play.
However, if a large amount of data is not required, it may cause the waste of a
transmission rate. If a large amount of data is required, it may cause the image quality
to be decreased.
Profile
SP (Simple Profile) is available up to the CIF resolution and 384kbit/s.
ASP (Advanced Simple Profile) is available up to the 4CIF resolution and 8000kbit/s.
GOV size
Enter the GOV (group of VOP) size. If users want to have a high quality of fast image
one by one, please decrease the value. For the purpose of general monitoring, please
do not change a basic value. Such act may cause a problem to the system
performance. For the details of GOV setting, please contact the service center.
