Abstract
A broadcast receiver receives a packetized stream. The broadcast receiver extracts display time information from the header of the received packetized stream, and extracts preparation trigger information including a target service identifier from the payload of the received packetized stream. If a current time is a preparation time designated by the extracted display time information, the broadcast receiver starts to prepare an object corresponding to the target service identifier for activation at a later time.
