5.3 Transmitter stream settings
You can either set up a point-to-point connection (unicast) or a multicast
connection to video stream receivers in the network that support the
multicast address.
For connections that need to pass through firewalls, the RTSP TCP port
can be separately defined. To avoid unnecessary network loading, the
video stream size can be defined by setting a maximum data rate, for
example, 80 Mbps (see below). For an optimal HD video stream, the data
rate setting should not be less than 30 Mbps. With “Auto stream” activated in
the stream configuration checkbox, the video stream starts as soon as a
connection between two units is made.
For additional security against eavesdropping, activate “Force HDCP” (High
Definition Content Protection) to protect video streams that are not from
HDCP encrypted sources. HDCP encrypted sources will always be
transmitted with HDCP encryption. This feature must be selected only at one
device to be activated.
Chroma Data Rate
This menu item uses the available bandwidth optimally for color
(chromaticity), then brightness (luminance). If the brightness is more
important than the color, the proportion of Chroma can be reduced.
When Chroma is set to 100%, 50% of the bandwidth is used for Chroma and
50% is used for Luma (brightness of the image points). In the extreme case
(black/white picture), only half of the set bandwidth is used because Chroma
generates almost no data.
