TSBroadcaster Properties, Continued 

 

system.streamEventDelay 

(0.1) Defines the period, in seconds, between each 

copy of a stream event 

system.needSomeOutput 

(false) Defines whether a system needs at least one 

connected and working output before it is declared 

as working correctly for monitoring purposes 

system.needAllOutput 

(false) Defines whether a system needs to have all 

its defined outputs working before it is declared as 

working correctly for monitoring purposes 

system.schedulerLeadTime 

(2.0) Defines how long, in seconds, before a 

scheduled event TSBroadcaster starts to update 

and distribute the new Transport Stream, so that 

the event is broadcast on time 

system.updateLeadTime 

(5.0) Defines how long, in seconds, before the start 

of an application playout TSBroadcaster starts to 

gather data from polled data update sources so 

that the data is available when the application is 

launched 

system.buildLaterInterval 

(20.0) Defines how long, in seconds, TSBroadcaster 

will wait before re-building a transport stream in 

response to data updates. This interval sets the 

lower limit on latency for non-rapid update data 

and provides resilience against “chattering” 

update sources. This interval does not apply to 

rapid updates 

system.update-

ConsolidationPeriod 

(0.25) Defines how long, in seconds, TSBroadcaster 

will wait before re-building a transport stream in 

response to a single data update. This setting 

provides automated data update systems with the 

opportunity to make several related updates 

within this period before the carousel is rebuilt, 

thus promoting data consistency 

system.shadow-

UpdatePeriod 

(30.0) Defines the minimum interval, in seconds, 

between successive updates of a partner
