The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Note Cisco DMP 4310G endpoints do not have any browser in this release
If you enter URLs for both video content and browser content, the actual result depends on a combination of these factors:
URLs cannot contain any more than 254 characters, cannot contain any spaces, and must use ISO/IEC-8859 (Latin-1) character encoding.
Your DMP has three stages for content substitution.
Note You can edit values that affect DMP behaviors during content substitution. These are the editable values:
When an HTTP status code of 404 or 500 prevents your DMP from obtaining the content that you scheduled it to play, your DMP enters stage 1 failover. Stage 1 operations for failover occur in a predictable sequence. Your DMP:
1. Verifies that you entered a URL in the Recovery URL field.
2. Verifies that the Recovery URL is reachable.
3. Verifies that the assets at the Recovery URL are valid.
4. Plays assets from the Recovery URL, instead of playing assets that were scheduled for playback.
When any operation fails during stage 1 failover, your DMP enters stage 2.
When an error of any kind prevents your DMP from retrieving and playing Recovery URL assets, your DMP enters stage 2 failover. Stage 2 operations for failover occur in a predictable sequence. Your DMP:
1. Verifies that you entered a URL in the Failover URL field.
2. Verifies that the Failover URL is reachable.
3. Verifies that assets at the Failover URL are valid.
4. Plays assets from the Failover URL, instead of playing assets from the Recovery URL.
Playback of the Failover URL persists until one of the following occurs.
When any operation fails during stage 2 failover, your DMP enters stage 3.
When errors interfere with stages 1 and 2, your DMP enters stage 3 failover. Stage 3 operations for failover occur in a predictable sequence. Your DMP:
1. Your DMP starts to play a video loop from ROM, which shows a butterfly beating its wings.
2. Playback of the video loop persists until one of the following occurs:
The video clip in ROM has no other purpose than stage 3 failover. You cannot change it and you cannot delete it.
Before it tries to download content from a webserver, your DMP first makes sure that the content exists at its expected address. Your DMP starts this validation by sending the webserver what’s called an HTTP HEAD request. Then, when the webserver responds within 1 second to verify that the expected address is valid, your DMP sends an HTTP GET request that triggers the actual download.
When the webserver takes more than 1 second to respond OR when its response is negative, your DMP enters a content substitution (“failover”) state. In this state, your DMP substitutes available assets for unavailable ones. So, instead of showing a black screen, this behavior causes an affected digital sign to play alternative content that you chose previously. The underlying logic for this behavior anticipates a serious problem and overcomes it gracefully.
However, this logic cannot account for all possible scenarios. When a webserver would otherwise verify (after 2 seconds, for example, or even 1.2 seconds) that an asset’s address is valid, your DMP misinterprets the delay and enters its content failover state unnecessarily.
You can use either of these methods to disable the timeout on just one DMP (CSCua03897).
– < DMP_FQDN > is the DNS-resolvable hostname for exactly this DMP.
– < password > is whichever password you set most recently for this DMP’s admin user.
Note To reenable the timeout, change the set_param command string to: video.force_wget_use=1&mib.save=1.
TVzilla supports some bitmap fonts and some TrueType fonts; it will substitute an installed font for any unsupported font.
Other typographic representations that you might show on a DMP display, such as the opening titles for a theatrical film, do not require that any font be installed. Similarly, when a font is embedded within a Flash file that you show, the Flash file will load correctly even if the corresponding font is not installed on your DMP.
See User Guide for Cisco Digital Media Manager 5.3.x on Cisco.com to learn precisely which fonts your DMP supports.
You can change how TVzilla, the embedded browser in your DMP, operates in certain situations.
Step 1 Click Browser in the Settings list.
Step 2 Enter or edit the required values, and then click Apply.
Step 3 Choose Administration > Save Configuration and, when the Save Configuration page appears, click Save.
Step 5 Stop. You have completed this procedure.
Step 1 Click to fill the screen on your DMP display with TVzilla.
The “video content” plane is hidden.
Tip Click Video to exit this full-screen mode.
Step 2 Stop. You have completed this procedure.
When you simultaneously play videos and run TVzilla, the “HTML content” plane is always on top of (in front of) the “video content” plane. However, you can adjust the visual density of TVzilla, so that it is fully opaque, fully transparent, or any degree of translucency between those two extremes.
The “video content” plane is always fully opaque. You cannot adjust it.
Step 1 Click Transparency in the Display Actions list.
Step 2 Enter or edit the required values.
Step 3 Click Apply to confirm that you are satisfied with the entry or change that you made and to record it in volatile memory.
After you click Apply, the entry or change takes effect. However, the previously defined value will return the next time that your DMP restarts.
Step 4 (Optional) Would you like to put all values into effect permanently, so that they persist even after your DMP restarts? Choose Administration > Save Configuration and, when the Save Configuration page appears, click Save.
Step 5 Stop. You have completed this procedure.
You can load a web page or other content on the HTML content plane (TVzilla). The HTTP URL that you enter persists until you use this procedure again to enter a different URL or until the next time that you restart your DMP. You cannot save the URL entry so that it persists after a restart.
Step 1 Click URL to be Displayed in the Display Actions list.
Step 2 Enter or edit the HTTP URL, and then click Go.
Step 3 (Optional) Would you like to stop showing the specified content? Do one of the following.
Step 4 Stop. You have completed this procedure.

Browser |
|
Indicates whether the browser should support Flash 6 or Flash 7. Our Flash support extends to SWF files only, not to FLV files. We do not support audio in SWF files. This setting is visible only when you use DMPDM on a DMP 430xG; it is not relevant to a DMP 4400G, which always uses Flash 9 or 10 for this purpose. |
|
Indicates whether you have rotated the HTML content plane and shows the amount of rotation. You might choose to rotate the HTML content plane if you have rotated your DMP display. The rotation feature applies only to content that plays on the HTML content plane. To play video vertically, you must first encode it vertically. |
|
Note Although this setting might look identical to a setting described in the “Adjust Whether TVzilla is Transparent, Translucent, or Opaque” section, they are different. You use this setting to configure transparency for the browser. The amount of transparency that you configure for all content that your DMP shows in the embedded browser. Values can range from 0 to 255, where: |
|
Indicates in milliseconds how long the splash screen persists on your DMP display when you start or restart your DMP. |
|
Screen Resolution Autodetection (requires DMP Display Autodetection) |
Indicates whether screen resolution detection is enabled. You can enable this feature only after you have enabled the feature to autodetect DMP display attributes (which is available from the DMP Display Attributes page). If you want to set the browser resolution manually, you must disable this feature. |
Indicates the HTML content pane width in pixels, if you are using the autodetected maximum width. Permitted values range from 640 to 1920. You might want to change this value if you know that your DMP display supports widths greater than the default value of 1366, but 1366 is the autodetected width. You can edit this value only if you selected Enabled from the Screen Resolution Autodetection list. |
|
Indicates the HTML content pane height in pixels, if you are using the autodetected maximum height. Permitted values range from 480 to 1080. You might want to change the value of you know that your DMP display supports heights greater than the default value of 768, but 768 is the autodetected height. You can edit this value only if you selected Enabled from the Screen Resolution Autodetection list. |
|
Indicates in real time the width and height in pixels that the attached DMP display is showing, if you selected Enabled from the Screen Resolution Autodetection list and if your DMP uses an HDMI cable to attach to its DMP display. 1. Choose DMP Display Attributes. 2. From the DMP Display Autodetection (requires HDMI) list, choose Disabled. 3. From the Display Standard list, choose VESA_1360x768x60. 4. From the Interface (DMP display output) list, choose HDMI. These selections will apply 1360 and 768 as the width and height values to use, respectively, ensuring that your content for digital signage works as designed — despite the trivial 6-pixel deviation in the width value, as compared to the content creation guidelines. |
|
Indicates the HTML content pane width in pixels, if you are using a custom width. Permitted values range from 640 to 1920. You can edit this value only if you selected Disabled from the Screen Resolution Autodetection list. |
|
Indicates the HTML content pane height in pixels, if you are using a custom height. Permitted values range from 480 to 1080. You can edit this value only if you selected Disabled from the Screen Resolution Autodetection list. |
|
Cache (only when Internal Storage Access Mode is “Read and Write”) |
Indicates whether the browser is caching content to local storage on your DMP. Caching is possible only when you have selected the Read and Write option from the Internal Storage Access Mode list on the Internal Storage page. |
Indicates whether you have enabled the logging of system messages on your DMP. Choose an option: |
|
The IP address of the device that should collect syslog messages from your DMP. |
|
The URL for the content that your DMP will show during stage-one failover. If the value is wrong, you can edit it. If you edit it, your edits will not take effect until you restart your DMP. |
|
The number of milliseconds that your DMP should wait after each failed attempt to load the content from a URL, before it tries again. |
|
The number of times that your DMP should try to load the content from a URL before it considers that URL to be unreachable. |
|
The URL to show immediately on a DMP display after its attached DMP restarts for any reason, unless other content is scheduled to be shown. If the value is wrong, you can edit it. If you edit it, your edits take effect as soon as you click Apply. |
|
The maximum number of seconds that your DMP will wait for a response from the server that you identify in the Recovery URL field. |
|

Transparency |
|
Note Although this setting might look identical to a setting described in the “Adjust TVzilla Settings” section, they are different. You use this setting to configure transparency for the HTML content plane. The amount of transparency that you configure for all content that your DMP shows on the HTML plane. The HTML plane and the video plane can overlap and you will see the video content plane through the HTML content pane if both of the following are true:
Values can range from 0 to 255, where:
Note The HTML content plane might sometimes contain a graphic that is already partially transparent in its own right (so that, for example, its rounded edges look smooth against the background color). This type of transparency pertains only to interaction between that graphic and other objects on the same plane. So, if you then change the Browser Transparency value to 255, for example, this does not mean you will be able to see the video plane through the partially transparent graphic on the HTML content plane. Instead, in this case, the video plane is still completely hidden, as expected. |
