A METHOD FOR TRANSMITTING A BROADCAST SERVICE, A METHOD FOR RECEIVING IT AND AN APPARATUS FOR RECEIVING IT

摘要

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 the 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.
