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.
