Location Settings


If streams are currently active, altering any of the location settings may result in stream interruption.

The following tables list the Location configuration settings.


Mgt. Server Location (checkbox)Select this location as the HMP management server. The auto-generated routes on the gateway assigned to this location include a loopback destination to HMP. This allows HMP to record sources, generate source thumbnails, and identify source status at this location. Therefore, sources at other locations are not available for recording, have no generated thumbnails, and the source status icons always appear grey when they are actually viewable users.
NameEnter a name for the location. This name is selectable on the Locations list.
Default LocationDisabledSelect this location as the default. The default location's Media Gateway is used when a user whose IP is not in any of existing location ranges accesses HMP. The default location is displayed in bold in the Locations list.
Media Gatewaysnone(Optional) Select a gateway that delivers video to the location from the list of paired Media Gateways (if available). See Pairing Media Gateways to HMP.


HMP Connection ModeRendezvous for regular HMP systems, 
Listener for HA cluster configurations

(Management Server Location only) The gateways in the location set to "Mgt. Server Location" have an extra SRT destination/output to be used by HMP for recording purposes. This setting allows you to specify the SRT connection mode to use between HMP and the recording output on HMG:

  • Rendezvous


    Currently on IPv6 systems, SRT Rendezvous mode with HMG is not supported.

  • Listener
  • Caller


  • When HMP is in High Availability (HA) mode, the HMP Connection Mode is Listener (read-only).
  • If there is a conflict between HMP and HMG connection modes (i.e., if the selected values do not match), the connection mode defaults to Rendezvous.
Link Connection ModeAny

Select the link connection mode between locations on your network:

  • Any
  • Listener
  • Caller
OutputsMuxed HLS and Variant HLS enabled

Configure the recording outputs generated for each multi-site live source in each location to which they are routed:

  • Muxed HLS
  • Variant HLS
  • SRT


  • Muxed HLS is required for the Play STBs.
  • Uncheck the first two boxes to disable either or both of the Muxed HLS (HLS v3) and/or Variant HLS (HLS v4) outputs.
  • Or check the third box to enable SRT. This configures the Location so that STBs connect to a generated SRT Listener output on HMG (instead of consuming HLS). SRT-capable STBs (Play 2000 and 4000) in that Location then prefer SRT over HLS and be returned a suitable endpoint on the local HMG.
SRT Port Range31000-31999

Specify the port range to use for your SRT routes between HMP and connected Media Gateways at this location.


Each route uses an incrementing port. If an upper bound is defined and is lower than the number of ports needed, route outputs are not created and user service is impacted. Unbounded is recommended.

SRT Listener Port51000-51999

If SRT is selected in the Outputs field, specify the port range to use for SRT listener routes between HMG and connected STBs at this location.


Each route uses an incrementing port. If an upper bound is defined and is lower than the number of ports needed, route outputs are not created and user service is impacted. Unbounded is recommended.

SRT Latency500

(Optional) Specify the SRT output latency in milliseconds.


To avoid playback issues, we recommend latency values from 500 to 2500 milliseconds.

HLS Segment Duration10(Optional) Duration to balance low latency, tune-in time, and stream buffering (range = 1-15 seconds). In the case of HLS live, the duration must be no greater than 15, or it takes too long for the playlist to become available and the initial request is forced to time out.
Bandwidth Limit

(Optional) Maximum bandwidth in Mbps to control the rate of outbound traffic to this location.

UDP ToS0x88

(Optional) Enter the desired UDP Type of Service value in hex format (0x00-0xFF).

IP Address/Mask

In the first field, enter an IP address for the location. This is a unique IPv4/IPv6 address in the proper format.

To specify a subnet mask for the location, enter a netmask in the second field, either in dotted-decimal format (e.g., or CIDR notation.

A subnet mask is a 32-bit mask used to divide an IP address into subnets and specify the network’s available hosts. You can specify multiple IP addresses or subnet masks for a location.

Multicast Address/MaskIf licensed on your system, for multicast delivery, specify the multicast address and subnet mask for the location. To disable multicast, leave Multicast Address empty.
Multicast AES+FECDisabled

Check this checkbox to enable AES (Advanced Encryption Standard) and FEC (Forward Error Correction).


Typically you might turn off encryption due to interoperability issues with non-Haivision devices.

Disable Unicast FallbackDisabled

Check this checkbox to prevent users from falling back to HLS streaming if there are problems with the multicast.

The default behavior is to give up on a multicast stream that can't be received and go back to regular HLS viewing so that the video can always be seen. This adds latency to the stream but in small user environments doesn't really have other negative effects.

However, in large user environments where large numbers of users have trouble with multicast, the load from HLS streaming could overload the network or the server, so you may choose to disable the HLS fallback.

Multicast Port41000Specify the port to use for all multicast route destinations in this location.
Peer To Peer (P2P)Off

Use this switch to enable/disable peer-to-peer playback in this location for HLS streams. To enable peer-to-peer, first a valid P2P key must be populated in the System Settings > Security > Streaming settings. See Configuring HMP for Haivision Peer-to-Peer Video Delivery  for more details.


  • Only applicable for HLS output streams, which can be enabled in the Outputs setting.
  • Haivision Peer-to-Peer on HMP is currently in Preview Mode.
