Bitrate: Indicates the number of bits per second.

frame_rate: Indicates the number of frames that the

MPEG4 encoder will encode per second. The range of the

frame_rate is 1 – 30.

Angelo_PortNo: The port number is the zero index of the

Angelo series card. For example, if there are two PCI-RTV-24

Angelo cards (card 0, card 1) in the system, and each PCI-

RTV-24 has four ports, the first port of card 0 is “0”, and the first

port of card 1 is “4.”

Angelo_ChannelNo: Indicates the channel index of the port

described above. There are four channels per port and the first

channel index is 0.

Angelo_Color_Format: RGB24= 3

Angelo_Video_Format:

0: Full NTSC, with image size 640*480

1: Full PAL, with image size 768*576

2: CIF NTSC, with image size 320*240

3: CIF PAL, with image size 384*288

4: QCIF NTSC, with image size 160*120

5: QCIF PAL, with image size 192*144
