当前的流量系统允许附属公司以基于时间或基于事件的“窗口”格式安排插入商业广告。基于时间和基于事件的预订都是根据第6节（信息性）所述的网络通信提前设置的。 特定于节目的广告插入是指在特定的广播节目中安排并插入一个节目点，以避免在体育节目超限、延误、替代节目或其他与已发布的节目表不同的情况下，错误放置该节目点。

Current Traffic Systems allow Affiliates to schedule the insertion of commercial advertising in either a Time-Based or Event-Based "Window" format. Both Time-Based and Event-Based reservations are setup well in advance based on communication from the Networks as described in Section 6 (Informative). Program-Specific Ad Insertion is the scheduling and insertion of a Spot into a specific broadcast Program in order to avoid misplacement of the Spot as in the cases of sports overruns, delays, alternate programming or other variations from a published schedule.
