An appliance on which mutually interdependent but individually licensed software modules and an administrative console are preinstalled.
Digital Signage Module (DMM-DSM) software helps your organization to ingest, organize, manage, and deploy video and multimedia, including emergency messaging, for delivery to a network of Cisco Digital Media Players (DMP) and their attached displays.
Enterprise TV Module (DMM-ETV) software helps you to create, manage, and deploy television channels, programs, and menus for Enterprise TV on a network of Cisco Digital Media Players (DMP) and their attached displays.
Video Portal Module (DMM-VPM) software helps your organization to ingest, organize, manage, and deploy live video events and VoDs for delivery from Cisco Video Portal to any desktop-based web browser. You can use DMM-VPM to manage Q&A sessions during live broadcasts, synchronize slides to video in live event streams or VoD streams, and manage behaviors for closed-captioning.
Video Portal Reports (DMM-VPR) software helps your organization to understand who uses your Cisco Video Portal and measure how they use it.
Cisco Digital Media Players (DMP)
Highly reliable, IP-addressable, solid-state endpoints that process HD video, SD video, and multimedia data for playback on an attached TV or other type of display, such as an Cisco LCD Professional Series (LCD Pro) display. DMPs consume very little power and can be deployed quickly throughout your network without the burden of high ongoing operational cost. DMPs are compatible with Cisco Application and Content Networking System (ACNS) and Cisco Wide Area Application Services (WAAS) products for content distribution.
The firmware for DMPs provides a web-based “craft interface” to manage one DMP in isolation. This software is called Digital Media Player Device Manager, or DMPDM.
An appliance that serves live video events and VoDs for delivery to web browsers on desktop-based client systems. This appliance works in combination with the Cisco Digital Media Manager (DMM) appliance that controls it.
New and Changed Information
Cisco DMS 5.1. x delivers new and changed features in the following components:
NoteThe following requirements apply to client systems that access DMS-Admin, DMM-DSM, DMM-VPM, DMM-ETVM, and Video Portal Reports The following requirements apply to client systems that access DMS-Admin, DMM-DSM, DMM-VPM, DMM-ETVM, and Video Portal Reports
For all client systems, ensure that Java Runtime Engine (JRE) 1.6.0 or later is installed. Also confirm that it is configured to use English as its language and that it is working correctly. The JRE 1.6.0 release is part of Java Version 6.
To obtain the required JRE, go to http://javasoft.com , click Java SE , then download the latest JRE version.
Apple maintains and distributes its own implementations of Java software for Mac OS users. To learn if Apple has made available any JRE that is based on JRE 1.6.0, see http://www.apple.com/java . Alternatively, registered Apple Developer Connection (http://connect.apple.com/ ) members might find that Apple has released a preview version of a compatible JRE. We make no claims about the suitability of such software for any purpose and recommend that you test all software thoroughly before you rely on it.
DMM-DSM and DMPDM
Table 1 lists additional client system requirements to use DMM-DSM and DMPDM.
Table 1 Additional Requirements to Use DMM-DSM or DMPDM
Caution If you enter only an IP address during set up, the Cisco DMS appliances cannot communicate with each other. Cisco DMS appliances will not work correctly without a DNS server. Please enter a fully-qualified domain name (FQDN).
To maintain network security, your DMM appliances and Video Portal appliances use digital certificates to communicate. These certificates use the DNS-routable hostname to identify each appliance uniquely. Therefore, you must enter the DNS-routable hostname for each appliance during setup when prompted to enter the fully-qualified domain name (FQDN) in AAI.
You must also configure each of your DMS appliances in AAI to point correctly to the DNS server for your network and configure that DNS server to associate the IP addresses that your DMS appliances use with the FQDNs that their digital certificates use.
When setting up your DMS 5.1. x appliances, do not use “Cisco” as the instance name for your Video Portal appliance. We reserve the use of the Cisco name for other purposes, and all deployments will fail if you use this instance name.
You can upgrade from Cisco Digital Media System 5.0. x to 5.1. x . For more information, including requirements and procedures, see Upgrade Guide to Release 5.1.x for Cisco Digital Media System on Cisco.com.
Low Memory Causes DMP 4305G Endpoints to Restart Automatically
Rather than crashing when they run low on memory, DMPs are designed to restart automatically, which clears their memory and causes downtime of much less than 1 minute, as opposed to the lengthy downtime that a hard crash would cause. In the rare cases when DMPs do run out of memory and restart automatically, SWF files are almost always responsible. The known scenarios when this can occur are as follows:
The file size is greater than 500KB for your SWF file. Larger SWF files do work correctly in most cases, but we recommend as a best practice that you should always strive to use the smallest possible SWF files. Smaller files are far less likely to be burdensome to your DMPs.
Your SWF file uses bitmapped image files outside itself that have a very large file size, either individually or collectively. Any bitmapped image files that you use in the production of a SWF file should be small files. If a bitmapped file has a large file size, it is important for you to understand that merely reducing the height and width of its placeholder on your canvas in Adobe Flash (or any similar authoring tool that you might use to develop a SWF file) will not reduce the actual file size.
The web page that you are showing uses too many embedded SWF files.
Additionally, we recommend that you use the following guidelines when you create SWF files:
The resolution of the SWF can be up to 1920 x 1080 if the animations that are contained within the SWF are small and are restricted to a 640x480 region.
Avoid redraw of the whole screen in your Flash animation.
Multiple movements on different parts of the screen cause more slowdown than a concentrated movement.
The FLV recommended resolution should be 320x240.
Limitations That are Resolved in DMS Release 5.1.0
Cisco DMS 5.1.0 corrects many bugs from earlier releases, including the ones that Table 4 describes.
When adding an asset to DSM, be sure that its name does not include any non-ASCII characters. Although DMS can store the asset successfully, its nonstandard filename prevents the content chooser in DMD from loading it. In addition, DMPs cannot play a video asset from any URL that contains non-ASCII characters.
If you check the randomize option for a playlist in a DMD presentation, you cannot uncheck this option; therefore, if you open a presentation and the randomized option is unchecked and you save the presentation, the randomize option persists for the playlist.
Media library batch upload does not work properly when filenames contain spaces.
If you upgrade to Cisco DMS 5.0.2 from release 5.0 without first installing the license to use DMM-DSM 5.0, you are prevented after the upgrade from accessing the 5.0.2 versions of both DMM-DSM and DMM-ETV. Your DMM server shows an HTTP 500 error instead of DMM-DSM and an authorization error instead of DMM-ETV.
The DMP 4305G does not display correctly websites that have a User-Agent field in the HTTP header.
Video playback ends too soon on DMP 4300G endpoints, no matter whether the video asset is included in a playlist or embedded in a web page, if you have rotated the browser plane to 180 degrees or 270 degrees in DMPDM.
If you select the Flash 10 option instead of the Flash 9 option in DMPDM 5.0.2, Enterprise TV performance might be disrupted when you use any of these buttons on your remote control for DMPs:
Any unassigned buttons
DMPs cannot successfully follow an HTTP 302 redirect that changes the destination for a Video URL. This means that DMPs cannot play a video whose URL has changed, until the Video URL value points directly to the actual, changed URL.
Table 5 Limitations and Restrictions in Cisco DMS 5.0
Digital Media Player
Send DMP commands to DMPs in intervals of no fewer than 4 seconds between commands.
All services are brought down when you start a firmware upgrade on the DMP 4305G.
Workaround Manually restart the DMP.
Errors occur on DMP 4400G and DMP 4305G endpoints when video links are configured as the startup URL.
Workaround None. Use the video URL instead.
Video stops playing on the DMP 4305G when you insert a flash drive into the USB interface.
Workaround Do not insert a flash drive when the DMP 4305G is active. Only insert the flash drive when the DMP is idle, and then restart.
Digital Signage Module (DMM-DSM)
If the DMM appliance goes down temporarily or restarts, you must ensure that replication between the DMM and Video Portal has resumed by verifying that the “Replication to Digital Media Manager: Working” message displays in the Video Portal AAI.
DMP displays that are attached to your DMP 4300G endpoints show a white line on 4 sides when your playlists transition from playback of Shockwave Flash assets to playback of video assets.
When its resources are limited, a DMP 4305G endpoint resets without a splash screen and without illuminating the red LED that should be visible through the chassis front grille because of limited resources.
Workaround Upgrade to a DMP 4400G which is more powerful and does not exhibit this behavior.
Using the local file option to add a media asset that is larger than 2G causes the upload menu to remain open indefinitely.
Workaround None. This is a browser limitation. We recommend that you upload a file that is smaller than 2G and that you use an external server for large files.
DMP 4305G restarts after 15 seconds when playing the emergency_animated template.
Workaround None. This template is designed for the DMP 4400G. We recommend you do not play content on the DMP 4305G that is specific to the DMP 4400G.
If DHCP fails during first boot and you choose “no” when prompted for a static IP address, the DMM appliance installation stalls after 20 minutes and is unrecoverable.
Workaround Reimage the server with DMS recovery CD.
Digital Signage Module (DMM-DSM) and Enterprise TV Module (DMM-ETV)
When a DMD presentation and an advanced task are scheduled to run back-to-back, playback of the presentation does not stop when it should.
Workaround Avoid scheduling an advanced task to run immediately after playback of a presentation.
A DMP restarts unexpectedly (5 percent of the time) if video playback is in progress when you simultaneously use a file transfer task to download assets to the DMP.
Workaround There are two methods to work around this problem. Before you use a file transfer application, run the “Stop All Applications” system task on each affected DMP. Alternatively, you can use Cisco DMS Content Distribution (DMS-CD) instead of the file transfer task.
The total file size value for a playlist is reset to “N/A.” This occurs after you switch to WAAS mode, but only if Enterprise TV uses an asset that the playlist includes.
DMD prevents you from adding a URL to a nonvideo playlist.
Workaround Add the URL to your media library. Then, when you try again to populate the playlist, choose the URL entry that you saved to your media library, instead of trying to enter the URL manually.
The dashboard in DMM-DSM does not show scheduled tasks. This problem is limited to Microsoft Internet Explorer (MSIE) and seems to be solved when you restart MSIE. However, the behavior reoccurs again later.
Workaround Choose Tools > Internet Options in MSIE, and then click Settings on the General tab. Click Every visit to the page , and then click OK twice.
User role limitations do not apply to the Emergencies tab. Any DMM-DSM user can use it.
Workaround Consider very carefully which DMM-DSM users should have permission to work with your schedule and manage your DMP groups. Although all of the “Play in Future” features are suspended (for affected DMPs only) while a declared emergency is in progress, none of the “Play Now” features or “DMP Manager” features are suspended. Therefore, it is possible for a careless user or malicious user with sufficient permissions to start another event manually on the DMPs where an emergency message should play.
After you associate a ticker action in DMD with a box object whose width is greater than 1,600 pixels, and you configure the ticker to scroll instead of fade, playback performance suffers for non-video assets, such as Shockwave Flash animations, that the presentation should play.
Workaround Reduce the width of the box object in your design or configure the ticker to fade but not scroll.
DMD does not prevent you from adding video assets to a nonvideo playlist. Instead of showing a warning that it does not support this behavior, DMD removes the video asset silently from the playlist when you save the presentation.
Workaround Avoid adding videos to nonvideo playlists in DMD.
DMM-DSM does not prevent you from uploading to your media library two assets that use the identical filename but whose other attributes differ. After you do this, the content chooser for DMD shows only one of these two assets.
Workaround Change the filename for one of the files, and then upload it again to your media library.
The error messages are unclear in DMD when you use File > Save As to save a presentation with the identical name that a presentation template uses.
Workaround Avoid duplicating names for presentations and templates.
The workspace in DMD does not preview the text inside a box object when its vertical alignment value is set to “Bottom.” Although the preview feature fails in DMD, the presentation works as designed on the DMP displays where you show it.
Cisco DMS Content Distribution (DMS-CD) features of DMM-DSM do not support nested DMP groups. DMS-CD functions as if this group structure is flat and does not autodelete old assets from DMPs that it misunderstands to be part of multiple DMP groups.
Workaround If local storage is full on DMPs that should receive a deployment from DMS-CD, and these DMPs are in nested groups, use Play Now to deploy a command immediately to delete the obsolete files from them. After this cleanup is finished, try again to provision the new assets from DMS-CD as a scheduled, future event.
Cisco DMS Content Distribution (DMS-CD) might disrupt playback performance temporarily on your DMP 4400G endpoints. The disruption affects multicast video streams, HD videos, Shockwave Flash animations, and image assets that these DMPs show on their attached DMP displays while simultaneously downloading newly provisioned, large assets. Videos might become fragmented (contain artifacts), drop frames, or cut out during playback. Shockwave Flash animations might play slowly. Images might redraw slowly. DMPs might restart unexpectedly, in rare instances. These behaviors affect the DMP 4400G due to a hardware resource limitation.
Workaround You can configure bandwidth restrictions in your WAN that should help to alleviate these symptoms or eliminate them completely, depending on the system load of each DMP. Follow the best practices for DMS-CD that are described on Cisco.com, in User Guide for Cisco Digital Media System 5.1.x .
Cisco DMS Content Distribution (DMS-CD) might cause a DMP to restart unexpectedly. This occurs if you make selections in DMM-DSM to provision assets to an external USB drive (usb_2) that is not actually attached to the DMP.
Workaround Before you try to provision assets to an external USB drive, verify that the drive exists and is attached to the DMP. Choose Digital Media Players > DMP Manager , and then check the “External Storage MB. (Total/Free)” value that pertains to this DMP. The value should not be blank.
After Cisco DMS Content Distribution (DMS-CD) adds or deletes files on an external USB drive that is attached to a DMP, the DMP might mount this drive as Read-Only or might not mount it at all. Content distribution to or from usb_2 sometimes corrupts the file system on drives from certain manufacturers. In our testing, we have seen this on Western Digital Passport drives 0.5 percent of the time and on Maxtor drives 70 percent of the time. We have removed Maxtor from our list of supported manufacturers.
Workaround Disconnect the USB drive from your DMP and reformat the USB drive to use FAT32 as its file system.
VoD playback does not stop immediately in Enterprise TV on DMP 4300G and DMP 4305G endpoints when you choose the VoD parent folder from the menu.
When you make selections in DMM-ETV to show an on-screen PIN that mobile phone users can use to authenticate their phones for emulation of the DMP remote control, the PIN might take as long as 2 minutes to appear on-screen.
Workaround Wait 2 minutes.
The video preview feature for Enterprise TV sometimes shows the wrong preview. Also, you are prevented from switching from the preview to the full-screen video. Instead of full-screen video, you might see that a small black rectangle loads in the upper right corner of the DMP display. Furthermore, if you press the Show IP button on a DMP remote control, an empty box is loaded instead of the IP address. These behaviors affect a DMP 4400G endpoint that has been running Enterprise TV for several days.
Workaround Redeploy the task to start Enterprise TV.
In an ACNS/DMS integration, if an ACNS channel is deleted while still scheduled in DMS, the DMS playlist cannot be deleted in DMM-DSM.
Workaround Create the set of the channels that are used to work with DMM-DSM, and do not delete them. To remove a channel from ACNS, complete these steps. Before deletion, remove all schedules that are assigned to particular channel (past/current/future). Remove channel from ACNS only after you have removed the schedules.
On the Play in Future tab, scheduling monthly and yearly recurring jobs during a leap year results in scheduling anomalies for jobs that occur during the month of February in subsequent months and years.
If you upgrade or downgrade the firmware for a DMP group that contains more than 20 DMPs while those same DMPs are playing a DMD presentation (which uses video and Shockwave Flash assets), some of the affected DMPs might not restart automatically and their upgrade might not be completed. When this happens, you cannot access the affected DMPs through port 7777 or port 6666. However you can ping them and you can see a green light through the front grille of their chassis.
Workaround: Before upgrading any DMP group that contains more than 20 DMPs, complete these steps to clear the content being played:
1. In DMM-DSM, use the Advanced Tasks feature to create a new DMP Startup URL task that will clear the startup URL and restart your DMP:
For the task name, enter: Startup URL - Empty & Restart .
For the description, enter: Startup URL - Empty & Restart .
Do not enter anything for the Video URL.
Do not enter anything for the Browser URL.
Check the Reboot Necessary check box.
2. Save your work.
3. Under the Schedules tab, use the Play Now feature to submit the “Startup URL - Empty & Restart” task to your DMPs.
4. After your DMPs have restarted, submit the firmware upgrade or downgrade to no more than 20 of them at one time.
5. After the upgrade or downgrade is finished and the affected DMPs have all restarted automatically, use the Play Now or Play in Future method to run an advanced task on your DMPs to populate their Startup URL.
Is it compulsory or forbidden for us to disclose CSCsq62657 and CSCsj09611?
Digital Media Player
The Internal Storage page in DMPDM might show that the DMP 4300G or DMP 4305G file system is Read-Write, instead of Read-Only. This occurs after cycling a DMP (turning its power off and then on), which can sometimes cause its file system to mount local volumes incorrectly.
Workaround Use the Restart DMP page in DMPDM to soft-reset your DMP and restore normal permissions.
While showing a presentation that combines Shockwave Flash (SWF) assets and video assets (unicast or multicast streams), DMP playback of the video is choppy. This occurs only when a DMP starts, while it is loading SWF assets into memory, and is the result of limited CPU capacity.
DMP displays might go black for as long as 3 seconds when playback is transitioning from one video asset to another video asset.
Workaround To reduce the duration of the black screen interval between two videos, you can use DMM-DSM to turn off the failover URL for a DMP.
After you use a DMM-DSM system task to disable DMP failover, there is no indication in DMPDM that failover is disabled.
Workaround If you cannot use DMPDM successfully to enable DMP failover, check in to see if failover is disabled for that DMP in DMM-DSM.
DMPDM becomes unresponsive after you enter the wrong IP address to identify the DMM appliance that you use for centralized management. This happens only after you incorrectly enter the IP address of your DMM appliance.
Workaround Restart the DMP and, within 30 seconds, enter either 127.0.0.1 or the correct IP address for your DMM appliance.
When you submit an HTTP pulling task with a DMD presentation to a DMP, the DMP continues to play the currently playing presentation while pulling content.
Workaround: Determine whether you want to stop the playing presentation before you submit an HTTP pulling task.
Video performance becomes choppy on DMP 4300G and DMP 4305G endpoints while they are downloading updated RSS data for tickers.
Workaround None. This is the result of a processor limitation.
If you select the Flash 10 option instead of the Flash 9 option in DMPDM 5.0.2, DMP 4400G endpoints might exhibit choppy playback performance when playing Shockwave Flash assets.
Workaround Choose the Flash 9 option.
When a DMP uses Flash 10, the background color on its attached DMP display changes to white after 7 hours of continuous playback for any SWF object. After this same interval, the DMP remote control has no effect when you try to use its features to mute audio, adjust audio volume, or show which IP address the DMP is using.
Current CDETS status is Unreproducible
A DMP 4400G might stop responding to the volume control buttons on its remote control if you use the remote control to adjust the audio volume levels for assets that you are playing from local storage.
Workaround: Do not use your remote control in this way with a DMP 4400G while any of its locally stored assets are playing.
EDCS text leaves it unclear whether this is a limitation in DMM or if it is specific to the 4305. Which is it?
DMP 4305 endpoints cannot successfully transmit RS-232 commands to control SunBrite 46" all-weather displays.
When Cisco Video Portal plays a QuickTime video, the video is not centered in the browser. There is a white or black space under the video.
The Windows Media VoD video slider does not work in Firefox.
Workaround If you require this feature, use another supported browser than Firefox.
When you use Microsoft Internet Explorer 6.0 to log in to Cisco Video Portal, you cannot press the Tab key to move your cursor to the Password field.
Workaround Click in the Password field to move your cursor to it.
A Cisco Video Portal that uses Windows Media or QuickTime for video might reload constantly on client systems that use Firefox.
Remote Control Quick Start Guide for Cisco Digital Media Players
In some printings, the “Requirements and Limitations” section states incorrectly that the “Cisco Digital Media Player (DMP) 4400G devices, and 4305G devices after July 2008, ship with a remote control.” The remote control is an optional item that you must purchase separately.
Mounting Kit Assembly Guide for Cisco Digital Media Players
In some printings, Cisco product numbers are wrong for mount kits.
Any use of “69-180 2 -01” is incorrect. The correct part number is “DMP-PRCASE- 4305 -S1.”
Any use of “69-180 3 -01” is incorrect. The correct part number is “DMP-PRCASE- 4400 -S1.”
Quick Start Guide for Cisco Digital Media Player (4305G and 4400G)
Some printings of these two guides contain identical errors:
Quick Start Guide for Cisco Digital Media Player 4305G
Quick Start Guide for Cisco Digital Media Player 4400G
The errors are as follows:
The Concepts text on page 3 mentions “protective case” accessories for DMPs, which discourage tampering and prevent theft. The accessory category was renamed after these guides were printed. The category name is now “mount kit.”
Also because the accessory category was renamed, the topic “Learning About the Protective Case for DMPs” became invalidated in multiple ways after these guides were printed:
– The topic heading should say “Learning About the Mounting Kit for DMPs.”
– The topic text mischaracterizes the title for mount kit assembly documentation. The correct title is Mounting Kit Assembly Guide for Cisco Digital Media Players .
Any use of “69-180 2 -01” is incorrect. The correct part number is “DMP-PRCASE- 4305 -S1.”
Any use of “69-180 3 -01” is incorrect. The correct part number is “DMP-PRCASE- 4400 -S1.”
