Cabling Information for the SV-4K Media Player

Table 6 describes the cables that ship with the SV-4K hardware.

Table 6. Cables Shipped with the SV-4K Hardware

Cable Length Purpose

HDMI-to-HDMI 2 M (Required) Connects the SV-4K HDMIOut (male) to the HDMIIn

(male) port on the TV for digital audio and video support.

RS-232 DE-9 DCE/DTE Straight Through

IRExtender 2 M (Required for IRRemote) Connects to the IRport on the SV-4K front

Other Cabling Considerations

It is important for you to assess the ports available on the TVs at the venue so that you can get any additional adapters or cable types that are needed to connect the SV-4K to the TV.

2 M (Required for TVcontrol) Connects the SV-4K serial DTE (male) port

to a serial DCE (female) port on the TV.

panel to serve as an infrared signal receiver for the SV-4K.

Null Modem (Crossover) Cable

The SV-4K is a DTEserial device. Therefore, if the TV also has a DTE (male) serial port, then you will need to use a null modem (crossover) cable for the TV control connection.

HDMI-to-DVIAdapter

If the TVdoes not support HDMI In, then you cannot use the standard HDMI-toHDMIcable that ships with the SV-4K. However, if the TVsupports a DVI-D connection, then you can acquire a DVIadapter for the HDMIcable to make the HDMIto-DVIconnection.

Since this type of connection only supports video, you will also need to connect the SV4K audio port to the audio input ports on the TV if audio support is required.

6 of 68

Page 15

Audio Cables

Audio cables are not generally needed. However, there are a couple of cases where you might need to make an audio connection to the SV-4K:

l If you need to support an HDMI-to-DVIconnection from the SV-4K to the TV since

this supports video only.

l If you need to connect to external audio distribution equipment when audio is to

be distributed within an area.

Guidelines for Mounting the SV-4K

Consider the following guidelines before mounting the SV-4K:

l Does not fit in Sunbrite cases that might be in use for some Cisco DMP 4310G

outdoor deployments.

l Full dimensions with mounting brackets:

196.20 mm long / 164.15 mm wide / 61.65 mm high

(7.72 in long / 6.46 in wide / 2.43 in high)

l Weight: 28 oz / 793.8 grams.

l Attach to the wall using the brackets on each side of the device using 4 screws

(one for each bracket slot) that measure between 3.5 mm and 4.2 mm in diameter.

l Avoid blocking the right side panel so that LEDs can be seen for troubleshooting.

l Ensure all air vents are clear for proper cooling.

7 of 68

Page 16

l Choose a location that works with the required IRextender cable for infrared

support.

Unlike the DMP 4310G, there is no IR receptor built into the SV-4K device.

IMPORTANT: The tested range is about 20 ft. However, to achieve this range you must be sure to have the receiver facing outward. The receiver is enclosed and not visible.

LEDs on the SV-4K Media Player

The SV-4K has 8 LEDs in two banks of 4 on the right panel of the device. (Figure 4) shows normal operation for the SV-4K on a Cisco StadiumVision network.

Figure 4. SV-4K LED Bank

NOTE: Some of the LEDs apply to hardware features that are

not enabled for Cisco StadiumVision Director Release 4.0.

Table 8 identifies the SV-4K LEDs that are applicable to operation in Cisco

StadiumVision Director Release 4.0.

IRRemote for Cisco StadiumVision Director

Both the Cisco DMP 4310G and the SV-4K media players use the same IRRemote device shown in Figure 5. Generally, the IRRemote is used for TV control. However, even if you are not using the IR Remote for TVcontrol, it is important to realize that the IRRemote also allows you to get information to troubleshoot the media player.

NOTE: The IRRemote is not automatically shipped with the Cisco StadiumVision Director media players and must be ordered separately.

Figure 5 shows the description for each of the buttons on the Cisco StadiumVision

Director IRRemote.

Figure 5. Cisco StadiumVision IRRemote Button Descriptions

IR Remote Sensor and IR Extender

Unlike the DMP 4310G, the IR extender is required for the SV-4K media player because the SV-4K does not have its own IR receiver. For more information, see the

"Guidelines for Mounting the SV-4K" on page7.

The IR remote also is a critical troubleshooting tool so it is important to ensure that all media players can be IR-controlled even if it is not needed during normal operation.

Default Settings for the SV-4K Media Player

The SV-4K device ships from the factory with certain default settings. Upon running the start-up sequence and in communication with Cisco StadiumVision Director, the SV-4K default settings are changed.

RS-232 Default Settings on SV-4K

After processing the HTML run-time module from Cisco StadiumVision Director, the SV-4K is set to the following RS-232 default settings:

NOTE: The SV-4K uses the same defaults as the Cisco DMP 4310G, which matches the default settingsof most TVs.

l Baud—9600 (factory default is 115200)

l Parity—None

l Data Bits—8

l Stop Bits—1

l Flow Control—None (factory default is hardware flow control only)

For information about the new RS-232 commands for the SV-4K, see "Appendix: Serial

Key Considerations for the SV-4K

When you deploy an SV-4K, there are several things that you should know about its operation.This section highlights some of the important differences from the Cisco DMP 4310G that you should be aware of when deploying the SV-4K media player.

This section includes the following topics:

l Firmware Provisioning on the SV-4K, Page 15

l Auto-Provisioning on the SV-4K, Page 16

l IR Receiver for the SV-4K, Page 16

l Storage on the SV-4K, Page 17

l Synchronization on the SV-4K, Page 17

l Switch Communication on the SV-4K, Page 17

Firmware Provisioning on the SV-4K

The SV-4K firmware is not provisioned the same way as the Cisco DMP 4310G. The primary difference is that the SV-4K firmware upgrade cannot be manually launched by Management Dashboard DMP command, but is done automatically when the SV-4K device boots.

IMPORTANT: Before you power on the SV-4K device for the first time, be sure that you have completed the following configuration and tasks:

l Switch configuration, including the required LLDP for

proper POE+ operation.

l DHCPserver configuration.

l Uploaded the released firmware to Cisco StadiumVision

Director.

l Configured the auto-registration settings for the SV-4K to

properly provision its firmware.

However there are some common configuration tasks. Table 12 provides a summary of the firmware provisioning tasks for the SV-4K and DMP 4310G in the Management Dashboard.

15 of 68

Page 24

Table 12. Summary of Firmware Provisioning Tasks on the SV-4K and DMP 4310G

Firmware Provisioning Tasks SV-4K

Upload firmware to Cisco StadiumVision Director in the Management Dashboard

Configure "Firmware image to use" and "init.version" under Auto Registration Settings.

Upgrade the firmware from the Management Dashboard by selecting DMPs and running the Firmware Upgrade command to push the firmware to the device.

The DMP 4310G also uses the "init.build" property which does not apply to the SV-4K media

Yes Yes

No Yes

DMP 4310G

player.

Auto-Provisioning on the SV-4K

l The SV-4K is automatically provisioned with global configuration settings from

Cisco StadiumVision Director—but not in the same way as occurs for the Cisco DMP 4310G.

As part of the start-up sequence, the SV-4K retrieves the Cisco StadiumVision Director configuration, which includes all of the global settings for the SV-4K, such as NTPconfiguration, jitter settings, and so on.

l The SV-4K global settings are configured in the Management Dashboard by

going to:

SV Director Configuration > Global DMP Settings > SV-4K Settings.

l The SV-4K configuration in Cisco StadiumVision Director is provisioned each

time that the SV-4K device boots.

IMPORTANT: If you are running Cisco StadiumVision 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. NTPfor Cisco StadiumVision Director is configured using the TUI, and can be the same external server as is used for the Cisco DMP 4310G devices. For more information, see the Cisco

StadiumVision Director Server Administration Guide.

IR Receiver for the SV-4K

There is not an embedded IRreceiver on the SV-4K. You must use the IRextender cable to use the IRRemote.

16 of 68

Page 25

Storage on the SV-4K

The SV-4K provides a minimum of 120 GB of total solid-state storage, with 100 GBavailable for content.

To find information about available storage, select an SV-4K device in the Management Dashboard device list. Then, go to Settings > Storage in the device details area of the dashboard.

NOTE: The amount of available storage shown in the Management Dashboard reflects the total amount of space available on the SSD, not the actual storage pool available for content.

Synchronization on the SV-4K

The SV-4K supports synchronization of content played among a group of SV-4K devices using the Network Time Protocol (NTP) and Precision Time Protocol (PTP). NTPand PTPsettings are provisioned globally for all SV-4K media players.

The Cisco StadiumVision Director server is provisioned as the default NTPsource for both the Cisco DMP 4310G and SV-4K media players. When PTPis configured, only the SV-4KPTPmaster derives its clock using NTP.

Best Practices for SV-4K Deployment

Using Bar Code Scanners and TVLabels at Installation Time

NOTE: This practice requires that you have already defined your

Location names in Cisco StadiumVision Director.

To increase the speed and accuracy of media player deployment:

l Prepare TVlabels with the Cisco StadiumVision Director Location name in bar

code format.

l Obtain a bar code scanner to record the Location bar code and MACaddress from

the media player.

l Use the BATtool to upload data to Cisco StadiumVision Director.

Installer Workflow Example

An installer can follow these steps to use a bar code scanner with TV labels:

1. Mount the TV and media player.

2. Connect the TV and media player cables.

3. Attach a pre-printed label to TV.

4. Scan the Location bar code on the TV.

5. Scan the MAC address bar code on the media player.

6. Provide scanner to the supervisor or network administrator who downloads the data and formats it to be compatible with the Cisco StadiumVision Director BAT TSV format.

TV Requirements for SV-4K Compliance

For the optimal experience with the SV-4K media player, be sure that the site TVdisplays are compliant with the following specifications and resolution:

l High-bandwidth Digital Content Protection (HDCP)

l High-Definition Multimedia Interface (HDMI)

l RS-232 serial interface

l Capable of 1080p HDdisplay

20 of 68

Page 29

Guidelines for TVand Content Resolution with the SV-4K Media Player

The SV-4K is set to run in full high-definition (HD) 1920x1080 mode by the runtime software.

IMPORTANT: It is highly recommended that your TV supports a minimum of 1080p HDresolution. Lower resolution displays might need some additional configuration of the TV Display Specification configuration in Cisco StadiumVision Director to attempt to optimize the display. In some cases these TVs might cut off an area of the screen, rather than resize the graphics to the area as the Cisco DMP 4310G does.

The quality and expected resolution for video and graphics display for the SV-4K can be affected by several things:

l The resolution of the TVdisplay and its ability to negotiate to 1080p.

l The configuration of the sv4k.videoMode serial command in the Display

Specifications area of the Cisco StadiumVision Director Control Panel:

When set to a resolution, this value specifies the SV-4K signal resolution.

If the resolution is set to auto-detection, then the TV negotiates the signal resolution with the SV-4K.

l The template region size.

l The size of the original graphic and whether any scaling needs to happen.

NOTE: For more information about content and template guidelines, see the Content Creation Design and Specifications

Guide for the DMP 4310G and SV-4K.

Restrictions for Control Panel TV Display Specifications with the SV-4K Media Player

Before you configure TVdisplay specifications for use with the SV-4K media player, consider the following restrictions:

l The following Basic Info options are not supported:

X Position / Y Position

X Scaling / Y Scaling

21 of 68

Page 30

Configuring Resolution Under Control Panel Display Specifications

The Display Specification for a TV can either be configured for auto-detection of resolution by the TV, or set to a fixed resolution in the Cisco StadiumVision Director Control Panel.

Figure 6. SV-4K and Display Signal Resolution

22 of 68

l If the resolution is set to auto-detection, then the TV and the SV-4K negotiate the

signal resolution (Figure 6).

l If a resolution is specified in the Control Panel, then the content is resized

according to that setting. This is the requested SV-4K signal resolution shown in red in Figure 6.

l If the signal resolution of the SV-4K is set below 1920x1080 for any reason, the

content will be resized according to the template in use.

l The template in use and the corresponding content must match the signal

resolution.

To set the resolution for a display, complete the following steps:

1. Go to Control Panel > Setup > Devices > Display Specifications.

2. Select the TV that you want to configure.

Network and Switch Planning

This section includes the following topics:

l External DHCPServer Requirements, Page 23

l Connected Stadium Switch Requirements, Page 24

External DHCPServer Requirements

The SV-4K media player requires configuration of an external DHCPserver to provide IPaddressing to the devices. This service can be configured using Cisco Network Registrar (CNR) or another external server at the venue.

This section highlights some of the key requirements to plan your DHCP configuration. However, it does not describe all of the details for you to perform the configuration.

23 of 68

Page 32

NOTE: For more information and details about DHCP configuration, see the Cisco Connected Stadium Design Guide available on ciscoet.com to qualified Cisco StadiumVision partners.

DHCPConfiguration Guidelines for the SV-4K Media Player

Consider the following guidelines before configuring a DHCPserver for the SV-4K:

l Do not configure the Connected Stadium Switch as the IOSDHCPserver for

Cisco StadiumVision.

l Be sure to set the DHCP server for an infinite lease of IPaddresses to the SV-

4Kdevices.

l If you are supporting a deployment with both Cisco DMP 4310G and SV-4K

devices, you will need to configure an Option 43 string for each model.

l If the DHCP server is limited to a single Option 43 string per DHCP pool (such as

with a Cisco DHCP server), then be sure to configure a separate DHCP scope for the SV-4K media players.

l Configure the DHCP Option 60, Vendor Class Identifier string:

SV-4K string for North America: "Cisco SV-4K-NA"

SV-4K string for all other regions: "Cisco SV-4K-ROW"

l Configure the converted DHCPOption 43, Vendor Specific Option URL:

http://x.x.x.x:8080/StadiumVision/dmp_v4/scripts/boot.brs

where “x.x.x.x” is the IP address of the Cisco StadiumVision Director server.

IMPORTANT: The option 43 string must be converted to TLV format for compatibility with the SV-4K. For more information, see "Appendix: SV-4K and DHCP Option 43" on page63

Connected Stadium Switch Requirements

This section highlights some of the key requirements to plan your Connected Stadium switch configuration. However, it does not describe all of the details for you to perform the configuration. For configuration details, see the Cisco Connected Stadium Design

Guide available on ciscoet.com to qualified Cisco StadiumVision partners.

Switch Configuration Requirements for the SV-4K Media Player

Configuring the SV-4K Global Settings

This section includes the following topics:

l Information About Time Protocols and Synchronization on the SV-4K Media

Players, Page 32

l How to Configure NTP and PTPon the SV-4K Media Players, Page 34

Information About Time Protocols and Synchronization on the SV-4K Media Players

This section includes the following topics:

l Network Time Sources for the SV-4K Media Players, Page 32

l PTP Master and Members, Page 33

l DMP-to-DMP Content Synchronization, Page 33

l Zone-Based Video Wall Synchronization, Page 33

l Use Cases for Video DMP-to-DMP Synchronization with PTP, Page 34

Network Time Sources for the SV-4K Media Players

The SV-4K supports two different network time sources under the global SV-4K settings:

l Network Time Protocol (NTP)—This is the default.

l 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 media players.The Cisco StadiumVision Director server is provisioned as the default NTPsource for both the Cisco DMP 4310G and SV-4K media players.

NOTE: When PTPis configured, only the SV-4KPTPmaster derives its clock using NTP.

For the most accurate synchronization for video playback across SV-4K devices, the time on the target SV-4K players must be almost the same. NTP does not provide this level of time synchronicity and accuracy, so PTP is also required.

32 of 68

Page 41

PTP Master and Members

The SV-4K 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 devices are designated as eligible master candidates.

DMP-to-DMP Content Synchronization

The DMP-to-DMP Content Synchronization feature for the SV-4K 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 SV-4K 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 supports enhanced content synchronization methods for the SV-4K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 devices participating in a video wall.

The primary benefit of this form of synchronization is that if any SV-4K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. This form of synchronization is recommended for dedicated video walls that are running video content longer than 15 minutes.

If an SV-4Kdevice reboots in a video wall that is not using zone-based video wall synchronization (using normal DMP-to-DMP synchronization), the tradeoff is that the rebooting SV-4K synchronizes with the rest of the video wall at the next content item in the playlist, or at replay of a single-item playlist.

33 of 68

Page 42

Use Cases for Video DMP-to-DMP Synchronization with PTP

PTPis particularly beneficial for the following use cases in the Cisco StadiumVision network:

l 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, the background can be more visually appealing by using local video content.

l 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.

l 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 Media Players

By default, both NTP and PTP services are automatically enabled for SV-4K media players. The SV-4K media players use PTP to achieve optimal synchronization. However, an NTP source also must be used to provide initial clocking to the SV-4K devices that are elected PTP masters in the network.

This section includes the following topics:

l Restrictions for PTP on the SV-4K Media Players, Page 35

l Guidelines for NTP and PTP on the SV-4K Media Players, Page 35

l Modifying the PTP and NTP Configuration on the SV-4K Media Players, Page 37

l Verifying PTPOperation for the SV-4K Media Player, Page 39

34 of 68

Page 43

Restrictions for PTP on the SV-4K Media Players

Before you configure PTP on the SV-4K media players, consider the following restrictions:

l PTP messages will not cross VLANs. Therefore, PTP master candidates need to

be identified for each VLAN and configured in the Management Dashboard.

NOTE: For ease of configuration for venues with multiple VLANs, the system is configured by default to list all SV-4K devices as eligible PTP master candidates. However, be aware that although this simplifies configuration, the time that it takes for the SV-4Ks to arbitrate a master SV-4K device in each network will vary, and depends on the number of eligible devices in each network.

l Content synchronization for video playback on the SV-4K 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-4Ks 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 Media Players

Before you configure NTP and PTP on the SV-4K media players, consider the following guidelines:

l For new installations of Cisco StadiumVision Director Release 4.0, PTP is the

default time source for the SV-4K media players, with NTP as the default time source for the elected SV-4K PTP master.

NTPGuidelines

l Each SV-4K media player designated as PTP master (per VLAN) will use NTPas

its time source. The other SV-4K devices in the network operate using a PTPreference clock from the elected PTPmaster.

l When PTP is disabled (not recommended), all SV-4K players use NTP to set their

local clock.

35 of 68

Page 44

l The default NTP synchronization interval with the host time server is one hour and

is configurable.

l An NTPsource must be configured in Cisco StadiumVision Director. By default,

the Cisco StadiumVision Director server is configured as the SV-4K NTP host (just as with the Cisco DMP 4310G).

For more information about configuring an NTPsource in Cisco StadiumVision Director, see the "Configuring the Cisco StadiumVision Director Server System

Settings" module in the Cisco StadiumVision Director Server Administration

Guide.

PTPGuidelines

NOTE: For synchronized video playback, NTP alone cannot be

relied upon for SV-4K devicesand PTP must be used.

CAUTION: If you are running Cisco StadiumVision 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.

l PTP version 2 is supported only for the SV-4Kmedia players and applies globally

to all devices in the Cisco StadiumVision Director network when configured.

l 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 devices in the network are eligible as master candidates and will go through arbitration to designate a master for their respective subnets.

l If you revise the default PTP master candidates configuration, you must configure

one or more SV-4K 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.

l If there is an in-house PTP master for your network, leave the “PTP master

candidates” property value blank. However, this configuration is only supported for venues without multiple subnets.

Performing a Regular Reboot of the SV-4K Media Players

The best practice for maintaining normal operation of the SV-4K media players is to perform a weekly reboot of the devices.

NOTE: The Cisco StadiumVision Director reboot task applies globally to both the Cisco DMP 4310G and SV-4K devices.

For information about how to configure the Reboot DMP system task, see the How to

Configure the Reboot DMP System Task task note.

Verifying SV-4K Media Player Compliance

The Management Dashboard allows you to compare values on the SV-4Kdevice against required values configured in the Cisco StadiumVision Director SV-4K settings.

Figure 12 shows how an SV-4K device should appear when it is fully compliant with

the configured Cisco StadiumVision Director settings:

l Required Value—Value configured in Cisco StadiumVision Director, or

automatically set by the system.

l Value on Device—Setting that the SV-4K device is running.

Before You Begin Troubleshooting the SV-4K

Before you begin troubleshooting the SV-4K, you should follow the information in these topics:

l RMA Process for the SV-4K, Page 49

l SV-4K Diagnostic URL, Page 49

RMA Process for the SV-4K

The Return Materials Authorization (RMA) process is performed through a call to Cisco Technical Support to assess the problem for final troubleshooting to confirm the device problem.

To begin the RMAprocess for the SV-4K, complete the following steps:

1. Locate your symptom in the SV-4Ktroubleshooting topics and begin to isolate the problem by following the suggested troubleshooting steps.

2. If you cannot resolve the problem with any of the recommended troubleshooting steps, contact Cisco Technical Support to proceed with further troubleshooting and the RMA process.

SV-4K Diagnostic URL

Some of the troubleshooting steps for the SV-4K recommend that you open a browser and navigate directly to the SV-4K device using the following URL to further diagnose a

49 of 68

Page 58

problem:

http://sv4k-ip-address

The diagnostic URL requires a password for use. The password is set in the "defaultDmpAdminPwd" registry key in the Management Dashboard (the same password as for the Cisco DMP 4310G). The default username is "admin."

Be sure to reset the password from the default value as a security best practice.

CAUTION: Do not manually power off the SV-4K after changing the password. To change the SV-4K password, you must use the Power Cycle DMP switch command from the Management Dashboard to restart the device properly. To use this command, be sure that you have imported the switch data first.

NOTE: This password is also used for the Diagnostic Web Server (DWS), and is used by the Cisco DMP 4310G.

Troubleshooting PTPOperation for the SV-4K Media Player

This section identifies some of the symptoms related to problems with PTPoperation:

l Symptom: Local PNGs are not synchronized across SV-4K devices, Page 50

l Symptom: Playlists do not advance to the next content item on the SV-4K, Page

Symptom: Local PNGs are not synchronized across SV-4K devices

Troubleshooting steps:

1. Verify the PTPconfiguration on your SV-4K devices:

a. Go to:

Management Dashboard > SV Director Configuration > Global DMP Settings > SV-4K Settings

b. Verify that the PTP domain and PTP master candidates property configuration

is correct for your network.

50 of 68

2. Open your browser and navigate to one of the SV-4Ks:

http://sv4k-ip-address/ptp.html

Page 59

3. Enter the username and password.

4. Look for the message “PTP is not enabled.”

This message might mean that the device was not rebooted after changes to the Management Dashboard settings.

5. If the message appears, reboot the SV-4K device.

Symptom: Playlists do not advance to the next content item on the SV-4K

If the current PTP master becomes unreachable (shuts down, or becomes unreachable on the network), the PTP members will be unable to update their clocks and this condition will occur.

Troubleshooting steps:

1. Verify the PTPconfiguration on your SV-4K devices:

a. Go to:

Management Dashboard > SV Director Configuration > Global DMP Settings > SV-4K Settings

b. Verify that the PTP domain and PTP master candidates property configuration

is correct for your network.

2. Open your browser and navigate to one of the SV-4Ks:

http://sv4k-ip-address/ptp.html

3. Enter the username and password.

4. Identify the PTP master by finding the unit that has an "offsetFromMaster" value of 0.0.

Figure 14. Identify the PTP Master

5. Ping the master PTP device.

51 of 68

Page 60

6. If the master is not reachable and you have configured alternate masters but they are not reported as master after waiting for a minute, reboot one of the reachable PTP master candidates.

NOTE: Identifying the alternate master for this step can more easily be done if you are explicitly identifying the IP address of alternate masters, and not using the "*" wildcard to specify possible election of any SV-4Kdevice on the network.

7. If a device shows that it has not synchronized, reboot the device to force synchronization.

l Symptom: Black screen on the SV-4K TVdisplay/no multicast video stream, Page

l Symptom: No local control when external volume strategy configured, Page 55

Symptom: Black screen on the SV-4K TVdisplay/no multicast video stream

Troubleshooting steps:

1. Verify if multiple TV displays are showing a black screen for the same multicast video stream.

2. If multiple TV displays are showing a black screen for the same multicast stream:

a. Verify the SV-4K LEDs.

b. If the SV-4K LEDs are in normal state, verify that the Cisco StadiumVision

Director server has power and is reachable.

c. If all TV displays are the same and/or new model, test with a different, known-

working TV display model.

d. (Advanced) Test with laptop connected to the same switch port/interface as

the SV-4K with a problem, and see if the problematic video stream can be displayed using the open source VLC player.

Appendix: SV-4K and DHCP Option 43

The SV-4K media player receive firmware and configuration from StadiumVision Director, version 4.0 or higher. The SV-4K media player finds the StadiumVision Director server through the use of DHCP options (specifically, options 60 and 43). Option 60 is used to signal the SV-4K media player that the option 43 content is meant for it to be received.

l If you are supporting a deployment with both Cisco DMP 4310G and SV-4K

devices, you will need to configure an Option 43 string for each model.

l If the DHCP server is limited to a single Option 43 string per DHCP pool (such as

with a Cisco DHCP server), then be sure to configure a separate DHCP scope for the SV-4K media players.

In this example, a Cisco IOS DHCP is being used, which supports only a single pairing of options 60 and 43 can be used within a single scope (requiring two different IP scopes if there is a need to support both the Cisco DMP-4310G and the SV-4K media players). This article only provides the procedure for the SV-4K media player.

Example 1. SV-4K DHCP Scope

ip dhcp pool SV-4K

network 10.10.1.0 255.255.255.0

default-router 10.10.1.1

3.7269.7074.732f.626f.6f74.2e62.7273

NOTE: The periods in the option 43 string are automatically created by the IOS and ARE NOT TYPED when creating the ASCII string.An example of the raw ASCII string value as typed can be found below.

Example 2. Creating Option 60

Type the line as shown above. Possible variations are as follows:

63 of 68

Page 72

Some IOS versions may require the text enclosed in quotes “SV-4K-NA”. If the IOS doesn't accept a leading quote in the string, then quotations are not needed. SV-4K string for North America DMPs: "Cisco SV-4K-NA" SV-4K string for all other region DMPs: "Cisco SV-4K-ROW"

Example 3. Creating Option 43

Option 43 is a vendor-specific option. For the SV-4K media player, it needs to point to a specific URL to execute auto-registration, auto-provisioning, and to receive initial firmware and subsequent upgrades, etc. That URL is

http://x.x.x.x:8080/StadiumVision/dmp_v4/scripts/boot.brs (where x.x.x.x represents the

IPv4 address of the StadiumVision director server).

Different devices require option 43 information be presented in different formats.The SV-4K media player requires type-length-value (TLV) format for the data string. Specifically, the TLV format is constructed in the following manner:

l The string is built using hex values.

l The string begins with a two-character hex representation of the option 43 Type

(an option 43 sub-option).

l The second two-character hex representation is the length of the information

string, expressed in the number of ASCII characters of the string.

l Following the length value, the ascii string is typed out by using the two-character

hex representation of each character in the string.

For the SV-4K media player, the type designation is type 85 (decimal), expressed as type 55 (hex).

Example 4. Option 43

For the following URL string:

http://10.10.10.100:8080/StadiumVision/dmp_v4/scripts/boot.brs

The option 43 string would be as follows (except all on one line, without carriage returns) in the following format:

option 43 hex value

As shown below, the resulting URL above would be represented by the string below:

option 43 hex (there is a space here between ‘hex’ and the remainder of the string)

553E687474703A2F2F31302E31302E31302E3130303A383038302F5374616469756D 566973696F6E2F646D705F76342F736372697074732F626F6F742E627273

Using the description above and the ASCII lookup table below, the first characters of the string would be explained in the following way:

64 of 68

Page 73

553E687474703A2F2F

55 – the type code in hex

3E – the length of the characters to the right of the length value, expressed by counting the number of two-character ascii characters represented (form the chart below).

And the first few characters, one at a time, would be as follows:

68 74 74 70 3A 2F 2F

H t t p : / /

The IP address is then represented the same way:

31 30 2E 31 30 2E 31 30 2E 31 30 30

1 0 . 1 0 . 1 0 . 1 0 0

The remainder of the string is the text of the remainder of the URL.

NOTE: As a Linux OS device, the Cisco StadiumVision Director server is case sensitive, and the correct letter case must be represented in the ASCII text strings.

Tips

l To make creating the string easier, start the string with 55 and copy the remainder

of the ASCII string past the IP address, as these values never change.

l The example string had a length value of 3E (62 represented as a hex value).

NOTE: In this value, DO NOT represent 62 as the hex character values of 6 and 2: instead, take the decimal value of 62 and convert to its equivalent hex (base 16) value (62 was converted to 3E in the example). Decimal-to-hex converters are easily found on the Internet, and most computer calculators have a decimalto-hex function available, possible under an advanced feature.

l The example IP address was 12 characters long which leaves the remainder of

the hex string to be 50 characters long. Add the number of ASCII characters in your IP address (including the dots!) to the known 50 characters and create your string length value to replace the 3E.

This technical information can be used to program other 3rd-party DHCP servers.
