To Add A Video Profile - Samsung SNO-5080R User Manual

To add a video profile

You can add as many codecs as necessary so that a variety of profiles can be applied
according to the recording condition.
1. Select a profile number.
2. Provide the name and select a codec.
3. Specify the conditions under which the codec will be applied.
4. Specify the details of the selected codec including resolution and frame rate.
• Resolution : Set the video size of the MPEG-4, H.264, and MJPEG files.
• Framerate : Specify the frame rate.
• Compression : Specify the compression rate of the video.
• Bitrate control : You can select one from constant bit rate and variable bit rate for
compression. Constant bit rate (CBR) varies the video quality and fixes network
transfer bit rate, while variable bit rate emphasizes the quality by varying network
transfer bit rate.
• Target bitrate : Specify the bit rate at which you will transfer the video.
• Encoding priority : You can set the video transfer method to Framerate or
Compression.
• GOP size : Select a GOP size between 1 and 15.
• Profile : The H.264 profiling method is fixed to <High>.
• Entropy coding : Reduce the possible compression loss due to encoding.
• Multicast(VNP) : Specify the use of the VNP protocol.
- IPv4 : 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 VNP packet.
• Multicast(RTP) : Specify the use of the RTP protocol.
- IPv4 : 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 GOP size?
GOP (Group of Pictures) is a set of video frames for MPEG-4 and H.264 format
compression, indicating a collection of frames from the initial I-Frame (key frame) to the next
I-Frame. GOP 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.
You can set between 1 and 15 for the MPEG-4 and H.264 CODEC.
