You can choose between the code algorithms H.264 MP and H.264 BP+ for each H.264 data
stream. As well as the Stream profiles, you can also select a profile for the M-JPEG image
transmission.
1. Select the required profile for every data stream.
2. Select the required code algorithm for every H.264 data stream.
You can change individual parameter values of a profile and you can also change the name.
You can switch between profiles by clicking the appropriate tabs. Click H.264 MP, H.264 BP+
and M-JPEG at the bottom of the tabs to change specific settings for the code algorithm in
question:
– H.264 MP
This profile setting represents H.264 Main Profile and offers the maximum configuration
options for the H.264 code algorithm. With it, you can achieve the best image quality at
the lowest bandwidth.
– H.264 BP+
This profile setting represents H.264 Baseline Profile plus, which uses a function from
the Main-Profile tool set to support interlace video. In contrast to the pure H.264
Baseline Profile, a resolution of 4CIF is possible. This setting should be selected if you
want the video stream to be displayed by a hardware decoder. In the process, the bit rate
is limited to 2.5 Mbps.
– M-JPEG
The bit rate can be set at a higher value for the M-JPEG stream than for the video stream.
CAUTION!
Hardware decoders VIP XD and VIP X1600 XFMD can only process algorithm H.264 BP+. Bear
this in mind when configuring profile settings.
CAUTION!
The profiles are rather complex. They include a large number of parameters that interact with
one another, so it is generally best to use the default profiles.
Change the profiles only once you are fully familiar with all the configuration options.
In the default setting, Stream 2 is transmitted for alarm connections and automatic
connections. Bear this fact in mind when assigning the profile.
