METHOD AND APPARATUS FOR BROADCAST DATA RECEPTION

摘要

PURPOSE: A method and a device for receiving broadcast data are provided to supply the first mapping information to quickly access only a desired IP packet, thereby increasing data processing speed. CONSTITUTION: The first mapping information is received(S910). The first mapping information comprises mapping information between an IP address and a transmitting channel. The IP address corresponds to an IP packet group including at least one IP packet. The IP packet group is loaded in the transmitting channel. The transmitting channel in which the IP packet group is loaded is accessed based on the first mapping information. The IP packet group is obtained from the accessed transmitting channel(S930). The IP packet group is transmitted through a data transmitting channel.
