Understanding Content and TV Resolution
There are several factors that determine the final resolution of your content on a TV display, including the model of media player deployed.
Physical and Signal Resolution
Physical resolution is the actual number of pixels supported by the TV display. Signal resolution is the resolution communicated between the media player and the TV display. These signal resolutions are negotiated between the media player and the display.
The physical resolution of the TV display and the negotiated signal resolution do not necessarily have to match. However, the signal resolution from the display and the media player must match for successful communication under almost all circumstances.
TVs smaller than 1920x1080 in physical resolution also can support a signal resolution of 1920x1080.
For TV-based tile-matrix video walls, the physical resolution is defined as the combined resolution of all of the displays. However, the signal resolution is likely to be different. For example, in a 2x2 video wall with TV displays of 1920x1080 resolution, the physical resolution of the video wall is 3840x2160, but the signal resolution would be 1920x1080.
For the SV-4K media player, you can override the negotiated signal resolution by configuring a requested signal resolution in the Cisco Vision Director Control Panel. See the Configuring Resolution Under Control Panel Display Specifications
Canvas and Template Resolution
Canvas resolution is the area on which the web browser draws, which ultimately determines what area can be shown on the display.
The canvas resolution is represented by the configurable template resolution in Cisco Vision Director. To be visible on the display, the template resolution must be able to fit within the canvas resolution.
Cisco Vision Director Template Resolution
Cisco Vision Director Release 4.0 supports the same template resolution on both media players:
Canvas and Template Resolution Behavior on the SV-4K
For the SV-4K, the canvas resolution is mapped to signal resolution for resolutions below 1920x1200. For more information about signal resolution, see Physical and Signal Resolution.
For example, with content resolution of 1280x720, the SV-4K canvas and signal resolution also will be 1280x720.
Any content greater than this resolution (for example, anything at pixel 1281 and beyond) will not be displayed. Higher resolution content will not shrink to fit the canvas.
If you are using a 1920x1080 template for a TV that has a signal resolution of 720p, the SV-4K template canvas will be cropped not shrunk. Therefore, you must specify the correct template to match your signal resolution and your content must match the template.
Guidelines for TV and Content Resolution with the
SV-4K and DMP-2K Media Player
The SV-4K and DMP-2K 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 Vision Director to attempt to optimize the display. In some cases these TVs might cut off an area of the screen.
The quality and expected resolution for video and graphics display for the SV-4K and DMP-2K can be affected by several things:
■The resolution of the TV display and its ability to negotiate to 1080p.
■The configuration of the sv4k.videoMode serial command in the Display Specifications area of the Cisco Vision Director Control Panel:
■ When set to a resolution, this value specifies the SV-4K and DMP-2K signal resolution.
■If the resolution is set to auto-detection, then the TV negotiates the signal resolution with the SV-4K and DMP-2K as long as the TV supports negotiation.
I MPORTANT: If you are using a 4K display, you must configure a fixed resolution value of 3840x2160x60p in the sv4k.videoMode serial command in the TV display specification
■The template region size.
■The size of the original graphic and whether any scaling needs to happen.
Note : For more information about content and template guidelines, see the Cisco Vision Content Creation Design and Specification Guide.
Restrictions for Control Panel TV Display Specifications with the
SV-4K and DMP-2K Media Player
Before you configure TV display specifications for use with the SV-4K and DMP-2K media player, consider the following restrictions: The following Basic Info options are not supported:
■X Position / Y Position
■X Scaling / Y Scaling
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 Vision Director Control Panel (see Figure 18).
Figure 18 SV-4K and Display Signal Resolution
■If the resolution is set to auto-detection, then the TV and the SV-4K negotiate the signal resolution, as long as the TV supports auto-negotiation ( Figure 18 ).
■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 18 .
■If the signal resolution of the SV-4K is set below 1920x1080 for any reason, video content will be resized according to the template in use.
■The template in use and the corresponding content must match the signal resolution.
To set the resolution for a display:
11. Go to Control Panel > Setup > Devices > Display Specifications.
12. Select the TV that you want to configure.
13. Click Serial Commands.
14. Find the sv4k.videoMode command ( Figure 19).
Figure 19 SV-4K Resolution Setting in Display Specifications
15. Specify one of the values in SV-4K Resolution Values according to the desired resolution behavior.
Table 2 SV-4K Resolution Values
16. Click Save.
17. Reboot the SV-4K device.
Understanding Content Types and Sources in Cisco Vision Director
Content is defined as any digital media that is presented on a TV display using a digital media player in Cisco Vision Director.
Cisco Vision Director supports a variety of content types and data sources to create an impressive presentation of digital content at your venue.
External and Internal Data Sources
This section summarizes the external and internal data sources that are available using the Data Integration interface to bring additional content into Cisco Vision Director.
For more information, see the Cisco Vision Director Data Integration Guide.
■RSS Feed (RSS 2.0)
Generic Data Sources
Cisco Vision Director also can support Generic Data Sources from the following source types:
■Supports automatic translation of MySQLand SQLServer database formats to XML data in Cisco Vision Director.
■National Football League (NFL) Game Statistics and Information System (GSIS) Cumulative Statistics
■NFL GSIS Game Clock
Other Data Sources
■Table Lookup (internal or external data source)
■The Table Lookup feature for data integration allows users to create multiple tables, each having multiple key-value mappings. Users can upload tables from a TSV file or create tables and mappings from the Cisco Vision Director UI.
■Once tables are created, a custom XPath function can be defined to look up values from these tables for specified keys.
■The Table Lookup feature for data integration supports the following primary use cases:
■Custom Suite Welcome Messages
■Translation of Point-of-Sale (POS) codes to names for menu boards.
■System (internal data source)
POS Data Sources
■Internal Database PoS (internal data source)
■Menu Theme (internal data source)
■Daktronics All Sport 5000 Scoreboard Controller (basketball and hockey only)
■OES ISC9000 Intelligent Scoreboard Controller (basketball and hockey only)
HTML Pass-Through Content
Cisco Vision Director allows you to render simple HTML browser content (with some restrictions) on the Cisco DMP and SV-4K media players by including an external URL in a playlist and scheduling it in a script.
The content is not actually stored in the Cisco Vision Director content repository (CMS), and any changes to the content on the external site page are dynamically updated on the DMP or SV-4K when the script restarts.
Menu Board Content
IMPORTANT : The SV-4K does not support deployment of menu board data using the DMB gadget archive (GAR) or for in-suite ordering. However, stores data and DMB menu theme data can be deployed on the SV-4K using data integration and widgets.
Cisco Vision Director supports three overall methods of Point of Sale (POS) integration for menu board implementation:
■ Hybrid DMB and Data Integration —POS Integration (NCR/Quest and Micros) using internal DMB data integration and widgets.
■ Data Integration Only —Third-party POS vendor integration using the POS API and data integration and widgets.
For More Information

■ Cisco Vision Director Data Integration Guide— Describes the differences between the DMB application and using POS data sources for menu board creation, deployment guidelines and configuration tasks, and widgets tool information and examples.
RSS Ticker Feeds
A ticker is a region that displays content received from an RSS feed (news, weather, or other dynamic information) over a customizable background. RSS feeds can come from external or internal sources. Venue operators can use RSS feeds to publish their own in-house promotions or other proprietary messaging.
Data Integration Method
IMPORTANT : This is the only method supported by the SV-4K media player.
The Data Integration method was introduced in Cisco StadiumVision Director Release 3.1 (now Cisco Vision Director) to add RSS data sources and modify their layout using the Widgets tool.
For more information, see the Cisco Vision Director Data Integration Guide.
Static Graphic Sources
Static graphics are images used for advertisements or informational messages that do not require motion.
Static graphics can be added to Cisco Vision Director in two ways:
■Using the Import button on the Control Panel Content screen.
Cisco Vision supports the basic sources of video content:
■Video from the headend (in-house, terrestrial TV, satellite and cable providers feeds, typically multicast).
■Video locally stored and played through a video playlist or a mixed media playlist (beginning in Release 3.1).
■Video streamed from a laptop or other supported device connected to the HDMI-In port (SV-4K media player only beginning in Release 4.1).
Video Content Sourced Using HDMI-In on the SV-4K
Cisco Vision supports two ways to source local video content using the HDMI-In port on the SV-4K media player:
■Encoding streamed video as a channel in Cisco Vision Director.
■Encoded HDMI-In video on the SV-4K can be started and stopped using multiple local control methods, as well as within Cisco Vision Director:
■User Control API
■Configuring Local HDMI-In as a video source in a region that is controlled using script states only.
IMPORTANT: The HDMI-In port on the SV-4K media player can only be supported either as a source to video region or source to encoder as a channel, but not both.
Therefore, you cannot have a script in a state which tunes to the HDMI-In as video source in a region, and then transition to the next state where you are streaming video from HDMI-In.
