•
Encoding priority : You can set the priority of video transmission to frame rate or
compression.
•
GOV length : It specifies the distance (in terms of number of frames) between two
consecutive I-Frames in a video sequence when H.264 codec was selected. (One
I-Frame + 0~Several P-Frames)
•
Profile : You can select the H.264 profiling method.
•
Entropy coding : Reduce the possible compression loss due to encoding.
•
Smart codec : Specify the use of Smart codec.
M
`
The Smart Codec will be active only if the codec is of H.264 and the compression system is
CBR.
•
Multicast(SVNP) : Specify the use of the SVNP protocol.
- IP address : Enter an IPv4 address with which you can connect to the IPv4 network.
- Port : Specify the video communication port.
- TTL : Set the TTL for the SVNP packet.
•
Multicast(RTP) : Specify the use of the RTP protocol.
- IP address : Enter an IPv4 address with which you can connect to the IPv4
network.
- Port : Specify the video communication port.
- TTL : You can set the TTL for the RTP packet.
What is GOV length?
GOV(Group of Video object planes) is a set of video frames for H.264 compression,
indicating a collection of frames from the initial I-Frame (key frame) to the next I-Frame.
GOV consists of 2 kinds of frames: I-Frame and P-Frame.
I-Frame is the basic frame for the compression, also known as Key Frame, which contains
one complete image data. P-Frame contains only the data that has changed from the
preceding I-Frame.
For H.264 codec, you can determine the GOV length.
