Property syntax of content root object
Property Type Default Value Mandatory Since Version Description
name string null No 0.1.0

The name of the content. This property is only used if the content data is loaded at startup and can be used to set the content name. This value is displayed in the about panel of the Media Station X application.

version string null No 0.1.0

The version of the content. This property is only used if the content data is loaded at startup and can be used to add a content version. This value is displayed in the about panel of the Media Station X application.

reference string null No 0.1.134

The reference of the content data. This property is only used if the content data is loaded at startup and can be used to load the actual data (i.e. non-startup related data) from another location. This allows you to keep the start content data more dynamic (e.g. by reloading it on the fly).

Note: Please note that most properties (e.g. headline, items, pages, options, etc.) are ignored if this property is set, because the corresponding values are provided by the referenced data. Additionally, please note that it is also possible to indicate request actions instead of URLs (e.g. "request:interaction:{DATA_ID}@{URL}").

flag string null No 0.1.120

A custom content flag that can be evaluated by plugins and/or servers.

Since version 0.1.144, this flag can also be used to replace (and reload) the content data at runtime. For more information, please see Replace Action.

Since version 0.1.153, this flag can also be used to refocus content items by using the refocus property.

reuse boolean true No 0.1.0

Indicates if the content data can be reused. If this property is set to false, the content data is recreated each time it is displayed.

cache boolean true No 0.1.58

Indicates if the content data is being cached. This property can be used to disable the cache feature.

restore boolean true No 0.1.120

Indicates if the content data is restorable. If this property is set to false, the content data is not restored when the application returns from a link action. This property has no effect if the content is displayed in a panel.

Note: If the content is loaded via a menu and the menu data has set the restore property to false, this property is ignored.

important boolean false No 0.1.58

Indicates if the content data is important. This property can be used to enforce that the content headline is displayed. This property has no effect if the content is displayed in a panel or the content is not loaded via a menu.

Note: The content headline is not displayed if the content is loaded via a menu, because in that case the menu item label is used as headline.

wrap boolean false No 0.1.102

Indicates if the content data is wrapped. If this property is set to true, a corresponding menu can not be entered by using the navigation keys (i.e. left and right key). This property has no effect if the content is displayed in a panel or the content is not loaded via a menu.

Note: If the active content page has its own wrap property, this property is ignored.

compress boolean false No 0.1.123

Indicates if the content is compressed by 25%. This property is part of the hidden features. For more information, please see Compress Property.

preselect boolean false No 0.1.160

Indicates if content pages and items should be preselected by executing the corresponding page and seletion actions before a content scroll animation. By default, these actions are executed after a content scroll animation.

refocus number|boolean 0 No 0.1.153

Indicates if a content item should be refocused. The flag property is used to cache and restore the focus value.

  • 0|false: No content item is refocused.
  • 1|true: The cached focused content item is refocused by using the item ID (and the item index as fallback).
  • 2: The cached focused content item is refocused by using the item index only.

Note: To use this property, the flag property must also be set, otherwise this property is ignored. If a content item has a focus property set to true, the focus value is only cached but not restored.

transparent number|boolean 0 No 0.1.142

Indicates if the content background is transparent. By default, the content background is set to a semi-transparent gray to darken the underlying video/image and make the content more visible. This property has no effect if the content is displayed in a panel.

  • 0|false: The content background is not transparent.
  • 1|true: The content background is transparent.
  • 2: The content background is only transparent if no video/audio is active or the active video/audio has set the extended property "control:transparent" to "true". For more information, please see Extended Properties.

Note: If the active content page has its own transparent property, this property is ignored.

type string "pages" No 0.1.0

The type of the content items.

  • "pages": The content items are displayed as pages in horizontal direction.
  • "list": The content items are displayed as list in vertical direction.

Note: If the "list" type is used, content pages are stacked (i.e. vertical gaps between content pages are removed). This property has no effect if the content is displayed in a panel, because panels always use the "list" type.

preload string "none" No 0.1.92

The preload mode of the content pages (available for type "pages" and "list"). This property can be used to preload the next and/or previous visible page (e.g. to preload images, to pre-perform live updates, etc.). By default, this feature is disabled.

Note: Please use this feature wisely, because preloading pages can decrease the performance.

  • "none": Preload no pages.
  • "next": Preload the next visible page.
  • "prev": Preload the previous visible page.
  • "full": Preload the next and previous visible page.
headline string null No 0.1.0

The headline of the content.

Note: This property has no effect if the content is loaded via a menu, because in that case the menu item label is used as headline. Since version 0.1.58, you can set the property important to true to enforce that this property is used.

This property supports Inline Expressions.

background string null No 0.1.0

The background image that is used if no other background is set at lower levels. If the content data is loaded at startup, this background image is used as default.

extension string null No 0.1.82
