Metadata congurations
Click “Metadata” under the Media Conguration menu. Metadata
Congurations page appears on the screen. You can add a metadata
conguration to an existing media prole, adding a metadata conguration
to a prole means that streams using that prole contain metadata. Four
metadata congurations are supported. In addition to video analytics
information, metadata can transmit PTZ camera status and position to the
Onvif client. Carrying other events such as “loss of video signal” is done by
metadata channel. Metadata transmits video analytics information like
motion detection over RTP stream in XML format. Currently MPH transmits
motion detection information, PTZ camera status (feedback) and video loss
event over metadata channel.
_________________________________________________________
User dened alias name for metadata conguration (max 64 chars).

Enable/disable scene description. When enabled, adds video analytics
results from each analyzed frame to metadata. With motion detection this

You can set a multicast address and port number for a Metadata stream,
the multicast address can be the same as video stream multicast address
but with different port number.

If enabled, metadata streaming starts automatically after reboot (does not
immediately start or stop streams).
Denes QoS class in differentiated services (DiffServ) trafc management.
DSCP/DiffServ (Differentiated Services Code Point) is a eld in the IP
headers that affects the priority of packet in the network per hop basis.

Quality of Service (DSCP):
Metadata is a data channel and one
of the Onvif features which can carry
events, PTZ status, and/or video
analytics data for network video
devices.
Note! Parameters cannot be
changed when streaming is active.
Note! Only even port numbers can
be used for RTP, and then the
following odd port number shall be
used for RTCP (RFC 1889).
