Location Settings

Note

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

The following tables list the Location configuration settings.

Information

Setting	Default	Description
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.
Name	—	Enter a name for the location. This name is selectable on the Locations list.
Default Location	Disabled	Select 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 Gateways	none	(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.

Networking

Setting	Default	Description/Values
HMP Connection Mode	Rendezvous 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 Note Currently on IPv6 systems, SRT Rendezvous mode with HMG is not supported. Listener Caller Note 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 Mode	Any	Select the link connection mode between locations on your network: Any Listener Caller
Outputs	Muxed 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 Note 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 Range	31000-31999	Specify the port range to use for your SRT routes between HMP and connected Media Gateways at this location. Note 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 Port	51000-51999	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. Note 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 Latency	500	(Optional) Specify the SRT output latency in milliseconds. Note To avoid playback issues, we recommend latency values from 500 to 2500 milliseconds.
HLS Segment Duration	10	(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 ToS	0x88	(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., 255.255.0.0) 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/Mask	—	If 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+FEC	Disabled	Check this checkbox to enable AES (Advanced Encryption Standard) and FEC (Forward Error Correction). Tip Typically you might turn off encryption due to interoperability issues with non-Haivision devices.
Disable Unicast Fallback	Disabled	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 Port	41000	Specify the port to use for all multicast route destinations in this location.
