Live Object

The live object can be used to periodically update content items (e.g. with live data, playback progress, etc.). It can have following states.

• "init": The initial state. Possible next states: "coming", "running", or "over".
• "coming": The object is not live yet or it was live before and can become live again. Possible next states: "running" or "over".
• "running": The object is live. Possible next states: "coming" or "over".
• "over": The object is not live anymore. Possible next states: "coming" or "running".

Property syntax of live object

Property	Type	Default Value	Mandatory	Since Version	Description
type	string	null	No	0.1.70	The type of the live object. If this property is not set, the current live object is removed. "schedule": The object is live for a specific schedule time, indicated by a start and end timestamp (i.e. the from and to properties). Possible states: "init", "coming", "running", and "over". "lifetime": The object is live for a specific lifetime (starting from the creation timestamp), indicated by a duration and delay (i.e. the duration and delay properties). Possible states: "init", "coming", "running", and "over". "airtime": The object is live for a specific airtime (running for the visible time), indicated by a duration (i.e. the duration property). Possible states: "init", "running", and "over". "playback": The object is live if the corresponding content item is currently being played. Possible states: "init", "running", and "over". Before version 0.1.146, this type can only be used if the corresponding content action is video:{URL} or audio:{URL}. Please note that in this case the corresponding content action URL is compared with the current player URL to check the live state. Since version 0.1.146, the source property can be used to define which property should be used to check the live state. "setup": The object is never live and has only the state "init", but the live action (i.e. the action property) is executed if the corresponding content item becomes visible. Note: The live object is only evaluated if the corresponding content item is visible. If the corresponding content item is visible, the live object is evaluated every second, regardless of the current state. Since version 0.1.74, live objects of type "playback" can also have the state "coming" if the corresponding content item contains the extension property resume:key. Please also note that live objects are evaluated on an overlay/underlay page, even if the overlay/underlay page is hidden.
from	number	0	No	0.1.70	The start timestamp of the live object in milliseconds. The value must be greater or equal than 0, otherwise it is ignored. Note: To use this property, the type property must be set to "schedule", otherwise this property is ignored.
to	number	0	No	0.1.70	The end timestamp of the live object in milliseconds. The value must be greater or equal than 0 and the start timestamp, otherwise it is ignored. Note: To use this property, the type property must be set to "schedule", otherwise this property is ignored.
duration	number	0	No	0.1.70	The duration of the live object in milliseconds. The value must be greater or equal than 0, otherwise it is ignored. Note: To use this property, the type property must be set to "lifetime" or "airtime", otherwise this property is ignored.
delay	number	0	No	0.1.70	The delay of the live object in milliseconds. The value must be greater or equal than 0, otherwise it is ignored. Note: To use this property, the type property must be set to "lifetime", otherwise this property is ignored.
source	string	"url"	No	0.1.146	The source that defines which property should be used to check the playback live state. "id": The corresponding content item ID is used to check the live state. If the corresponding content item does not contain an ID, the current live object is removed. "url": The corresponding content action URL is used to check the live state. If the corresponding content action is not set to video:{URL} or audio:{URL}, the current live object is removed. "key": The corresponding content item extension property resume:key is used to check the live state. If the corresponding content item does not contain the extension property resume:key, the current live object is removed. "current": The live object will never be in the state "coming", but will be in the state "running" once the player is running. "none": The live object will never be in the state "running", but will be in the state "coming" if the corresponding content item contains the extension property resume:key. Note: To use this property, the type property must be set to "playback", otherwise this property is ignored.
coming	object	null	No	0.1.70	The state object that contains the live content properties (e.g. title, titleHeader, titleFooter, etc.) and the live action if the live object is in state "coming". If this object does not contain live content properties, the live content properties from the live object are used. Note: To use this property, the type property must be set to "schedule", otherwise this property is ignored. The live action will only be executed once, if the live object enters the state "coming". Since version 0.1.74, live objects of type "playback" can also have this property.
running	object	null	No	0.1.70	The state object that contains the live content properties (e.g. title, titleHeader, titleFooter, etc.) and the live action if the live object is in state "running". If this object does not contain live content properties, the live content properties from the live object are used. This object can also contain following sub-state objects to use separate live content properties for specific quartiles. quartile1: This sub-state object is used if the progress is in range of 0.0 to 0.25. quartile2: This sub-state object is used if the progress is in range of 0.25 to 0.5. quartile3: This sub-state object is used if the progress is in range of 0.5 to 0.75. quartile4: This sub-state object is used if the progress is in range of 0.75 to 1.0. Note: To use this property, the type property must be set to "schedule", "lifetime", "airtime", or "playback", otherwise this property is ignored. The live action will only be executed once, if the live object enters the state "running". The sub-state objects do not support live actions. Since version 0.1.74, live objects of type "playback" can also contain the sub-state objects inside the coming property.
over	object	null	No	0.1.70	The state object that contains the live content properties (e.g. title, titleHeader, titleFooter, etc.) and the live action if the live object is in state "over". If this object does not contain live content properties, the live content properties from the live object are used. Note: To use this property, the type property must be set to "schedule", "lifetime", "airtime", or "playback", otherwise this property is ignored. The live action will only be executed once, if the live object enters the state "over".
execute	object	null	No	0.1.74	The execution object that contains the live action that is executed if the corresponding content action is set to "live" and the corresponding content item is executed. Note: To use this property, the type property must be set to "schedule", "lifetime", "airtime", or "setup", otherwise this property is ignored. If this property is set inside a state object (i.e. coming, running, or over), it is used (instead of this one) if the live object has the corresponding state.
color	string	null	No	0.1.70	The live content property of the corresponding content item.
title	string	null	No	0.1.70	The live content property of the corresponding content item. This property supports Live Inline Expressions. Note: Only if the title property has been set (to a non null value) in the origin data of the corresponding content item, it can be updated.
titleHeader	string	null	No	0.1.70	The live content property of the corresponding content item. This property supports Live Inline Expressions. Note: Only if the titleHeader property has been set (to a non null value) in the origin data of the corresponding content item, it can be updated.
