(Details are described in the next part “Advanced image setting skill”)
¾ ᇹVideo FormatᇺImage setting. It is adjusting the resolution, please refer to the table:

resolution PAL system NTSC system
D1(4CIF) 720*576 720*480
HD1(2CIF) 720*288 720*240
CIF 352*288 352*240
QCIF 176*144 176*120

refer to table 1.
¾ ᇹI Frame InvᇺIt means the number of frame P or frame B between key frames (frame I)
¾ ᇹRate TypeᇺWhen the VBR(Variable Bit rate) is chose, the video server will automatically
choose a proper stream according to the complex and movement condition of images and the
image quality is set by user, but the “stream rate” will not exceed. When the CBR (Constant Bit
rate) is chose, the video server will control the “stream rate” in the setting.
¾ ᇹImage QualityᇺImage quality. It is an important parameter which controls image quality; it can
be set in 5 levels. For setting please refer to “Advanced image setting skill”
