_________________________________________________________
Here you see how the media prole is assigned to a video source.
_________________________________________________________
There are three options; Every frame = IP, Every second frame = IBP,
Every third frame = IBBP.
MPEG-2 GOP format.
_________________________________________________________
Simple Prole (SP) is recommended only for decoder compatibility.
Interlacing toolsets are not used.
Advanced Simple Prole (ASP) Level 5 enables Macroblock-Adaptive
Frame/Field Coding (MBAFF) which offers better image quality and
better compression ratio with interlaced video signal. Recommended
choice when interlaced stream is selected (D1 and Half-D1 resolutions).
_________________________________________________________
Baseline Prole (BP) Level 3 is recommended only for decoder compat-
ibility. Interlacing toolsets are not used.
Main Prole (MP) Level supports eld encoding which which offers
better image quality and better compression ratio with interlaced video
signal. Recommended choice when interlaced stream is selected (D1
and Half-D1 resolutions).
_________________________________________________________
Denes video bitrate mode. There are three options available, variable
bitrate (VBR), constant bitrate (CBR) or capped VBR. Rate control is a
trade off between quality uctuations and bit rate variability.
Denes video frame rate (adjustable 1...30fps for PAL/NTSC).
Denes encoding frame interval; for instance when encoding interval is 1,
all frames are encoded, value 2 means, every second frame is encoded.
Species the order in which intra- and inter-frames are arranged. The
GOP is a group of successive pictures within an encoded video stream.
Each coded video stream consists of successive GOPs. From the pic
-
tures contained in it, the visible frames are generated. For instance if you
25 FPS video stream, GOP= 25 means one I-frame per full frame.
GOP = 13 means two I-frames per full frame. GOP = 5 means 5 I-frames,
20 p-frames per second
Encoded video image quality, can adjust in VBR or capped VBR mode.
Encoded video bitrate, 128Kbps...15Mbps.
_________________________________________________________
Enables or disables the trigger feature.
Keeps the event state unchanged for the dened period for instance if an
event clears quickly, it does not change its state for the dened timeout,
recommended 5 seconds.
_________________________________________________________
Select the event type.
The topic expression of the event.
Event description, lter and values.
_________________________________________________________
Timeout for RTSP session
_________________________________________________________
Destination IP address. Multicast: Multicast IP address / multicast group.
This multicast IP address has to be same at both encoder and corre-
sponding decoders. Unicast: IP address of receiving decoder.
UDP port number (0...65536). This number has to be same at both
encoder and decoder pairs. Use even port numbers only.
Time-To-Live for video packets = number of hops that a packet is permit-
ted to travel before being discarded by a router (0...255) .
Video streaming will automatically start after reboot. Changing autostart
does not immediately start or stop streams.
