Abstract
Methods and systems have been provided for preempting a secondary service provider from streaming information. The primary service provider sends an Ad-insert control packet for giving control of the streaming to the secondary service provider, during still periods determined on the basis of the Ad-insert control packet. When the primary service provider wants to take back control of streaming from the secondary service provider during the still periods, the primary service provider sends an Ad-insert preempt message. The secondary service provider is then preempted during the periods that are determined on the basis of the Ad-insert preempt message.
