Network Time Sources for the SV-4K and DMP-2K Media Players
The SV-4K and DMP-2K supports two different network time sources under the global SV-4K settings:

Network Time Protocol (NTP)—This is the default.

Precision Time Protocol (PTP)—Required for video wall synchronization feature and for DMP-to-DMP
synchronization.
NTP and PTP settings are provisioned globally for all SV-4K and DMP-2K media players. The Cisco Vision Dynamic
Signage Director server is provisioned as the default NTP source for all media players.
Note: When PTP is configured, only the SV-4K and DMP-2K PTP master derives its clock using NTP.
For the most accurate synchronization for video playback across SV-4K and DMP-2K devices, the time on the target
media players must be almost the same. NTP does not provide this level of time synchronicity and accuracy, so PTP is
also required.
PTP Master and Members
The SV-4K and DMP-2K DMP is capable to serve as a PTP master or as a PTP member, where members obtain their
time from the master. The PTP master, in turn, will get its time from an NTP server.
By default, all SV-4K and DMP-2K devices are designated as eligible master candidates.
DMP-to-DMP Content Synchronization
The DMP-to-DMP Content Synchronization feature for the SV-4K and DMP-2K media player synchronizes content
rendering of playlist items on the displays.
This synchronization includes transitioning from one item to the next (such as for still images), and more accurate
playback and rendering of local video content. For local video, this serves as the foundation for implementing video
ribbon boards and video walls. This requires cabling of a single media player per display.
Note: Widgets, external URLs, and multicast video tuning synchronization are outside the scope of this feature.
Improved content synchronization was first introduced in Cisco StadiumVision Director Release 3.2 on the DMP 4310G
through the use of the Network Time Protocol (NTP).
Cisco StadiumVision Director Release 4.0 and later supports enhanced content synchronization methods for the SV-4K
and DMP-2K only, with close synchronization of playlist item transition using the Precision Time Protocol (PTP).
Zone-Based Video Wall Synchronization
Zone-based video wall synchronization is an alternative form of synchronization available for SV-4K and DMP-2K devices
participating in a video wall. It makes use of a mechanism native to the SV-4K/DMP-2Ks that helps a group of media
players stay in content sync with a leader device over multicast.
The primary benefit of this form of synchronization is that if any SV-4K and DMP-2K device that is not the leader in the
video wall reboots, it will “catch up” to play whatever content item that the rest of the video wall is currently playing.
37
Deploying the SV-4K and DMP-2K Media Player
Configuring the SV-4K and DMP-2K Global Settings
If an SV-4K and DMP-2K device reboots in a video wall that is not using zone-based video wall synchronization (using
normal DMP-to-DMP synchronization), the trade-off is that the rebooting device synchronizes with the rest of the video
wall at the next content item in the playlist, or at replay of a single-item playlist.
The general guideline is to use zone-based video wall synchronization for dedicated video walls that are playing video
content longer than 15 minutes. While you can use this form of synchronization for all video walls, the synchronization
benefit is best seen with longer-playing video wall content.
Use Cases for Video DMP-to-DMP Synchronization with PTP
PTP is particularly beneficial for the following use cases in the Cisco Vision Dynamic Signage Director network:

Using video background for Dynamic Menu Boards (DMBs) that show a PiP of the live event.

With the DMP 4310 devices, the background is implemented as a SWF, whereas with the secondary video feature
on the SV-4K and DMP-2K, the background can be more visually appealing by using local video content.

Sponsored moment of exclusivity.

When a team scores a goal, a secondary video using the luma key feature can be shown onscreen overlaying a full
screen video showing the live event.

Video-based ads.

Ads in region 2 or 3 (or L-wraps) can now be video content. For L-wraps, the luma key will need to be used so that
the live multicast video can be seen.
How to Configure NTP and PTP on the SV-4K and DMP-2K Media Players
By default, both NTP and PTP services are automatically enabled for SV-4K and DMP-2K media players. The SV-4K and
DMP-2K media players use PTP to achieve optimal synchronization. However, an NTP source also must be used to
provide initial clocking to the devices that are elected PTP masters in the network.
This section includes the following topics:

Restrictions for PTP on the SV-4K and DMP-2K Media Players, page 38

Guidelines for NTP and PTP on the SV-4K and DMP-2K Media Players, page 39



Verifying PTP Operation for the SV-4K and DMP-2K Media Player, page 43
Restrictions for PTP on the SV-4K and DMP-2K Media Players
Before you configure PTP on the SV-4K and DMP-2K media players, consider the following restrictions:

By default, PTP messages will not cross VLANs and PTP master candidates need to be identified for each VLAN and
configured in the Management Dashboard.

However, in Release 4.1 and later releases, a configurable Precision Time Protocol (PTP) Time To Live (TTL) setting
in the Management Dashboard. The PTP TTL specifies the number of VLANs that can be crossed for selection of a
PTP master. The default value of 1 (recommended) means that each VLAN will elect its own PTP master.
Note: For ease of configuration for venues with multiple VLANs, the system is configured by default to list all SV-4K
and DMP-2K devices as eligible PTP master candidates. However, be aware that although this simplifies
configuration, the time that it takes for the devices to arbitrate a master device in each network will vary, and depends
on the number of eligible devices in each network.
38

Configuring the SV-4K and DMP-2K Global Settings

Content synchronization for video playback on the SV-4K and DMP-2K media player relies on precise time across
DMPs using PTP. The behavior is similar to content synchronization on the Cisco DMP 4310G. If SV-4K devices are
playing video and one of the devices reboots, the rebooting unit will restart video playback from the beginning and
will only synchronize with the other players when the next item in the playlist is rendered.

If SV-4K and DMP-2Ks are participating in zone-based content synchronization for video walls, with some enhanced
synchronization capability, the rebooting unit will synchronize with the current item being played by the device leader
in the video wall. For more information, see the “Working with Video Walls” section of the Cisco StadiumVision
Director Operations Guide.
Guidelines for NTP and PTP on the SV-4K and DMP-2K Media Players
Before you configure NTP and PTP on the SV-4K and DMP-2K media players, consider the following guidelines:

For new installations of Cisco Vision Dynamic Signage Director, PTP is the default time source for the SV-4K and
DMP-2K media players, with NTP as the default time source for the elected PTP master.
NTP Guidelines

Each media player designated as PTP master (per VLAN) will use NTP as its time source. The other SV-4K and
DMP-2K devices in the network operate using a PTP reference clock from the elected PTP master.

When PTP is disabled (not recommended), all SV-4K and DMP-2K players use NTP to set their local clock.
Note: For synchronized video playback, NTP alone cannot be relied upon for SV-4K and DMP-2K devices and PTP must be used.

The default NTP synchronization interval with the host time server is one hour and is configurable.

An NTP source must be configured in Cisco Vision Dynamic Signage Director. By default, the Dynamic Signage
Director server is configured as the SV-4K and DMP-2K NTP host (just as with the Cisco DMP 4310G).
Caution: If you are running Cisco Vision Dynamic Signage Director on a virtual server, then you should reference
a reliable NTP server running on a bare metal server, rather than relying on a clock from a VM environment that
can drift and is not accurate.

For more information about configuring an NTP source in Cisco Vision Dynamic Signage Director, see the
"Configuring the Cisco StadiumVision Director Server System Settings" module in the Cisco StadiumVision Director
Server Administration Guide.
PTP Guidelines

PTP version 2 is supported only for the SV-4K and DMP-2K media players and applies globally to all devices in the
Cisco StadiumVision Director network when configured.

PTP configuration includes a PTP domain and a set of master candidates:
—
PTP domain—Default is 0.
Be sure that this domain does not conflict with any other PTP domain (and multicast addressing) in use in your
network, and revise as needed. See Table 3 for more information.
—
PTP master candidates—Default is *.
This specifies that all SV-4K and DMP-2K devices in the network are eligible as master candidates and will go
through arbitration to designate a master for their respective subnets.
If you revise the default PTP master candidates configuration, you must configure one or more SV-4K and
DMP-2K devices as master candidates in a semicolon-separated list of IP addresses for each VLAN.
A minimum of two master candidates per network is recommended.
