Ad break models can be created customer specifically within Scheme and Programmer for each channel. An ad break model defines how the ad breaks should be distributed automatically onto the events or slots which are scheduled with a certain length on a certain channel and time period. An ad break model can be applied for a slot template within the Scheme. In addition, it can be applied for the events or slots in the Programmer. Here, all ad breaks are inserted automatically according to the predefined template.
