Abstract

A method of transmitting a broadcast signal includes encoding mobile data for FEC (Forward Error Correction); encoding signaling information for signaling the mobile data; allocating the encoded mobile data and signaling data into a transmission frame; and transmitting the broadcast signal including the transmission frame, wherein the transmission frame includes a service signaling table having service_type information identifying a type of a service of the mobile data and hidden information indicating whether the service of the mobile data is hidden or not.

First claim

The invention claimed is:

1. A receiver for processing a broadcast signal, the receiver comprising:
a tuner to receive the broadcast signal including service data of a service and signaling information for acquisition of the service;
a demodulator to demodulate the service data and the signaling information;
a decoder to decode the demodulated signaling information,
wherein the signaling information includes first signaling information and second signaling information,
wherein the first signaling information includes type information for identifying a type of the service, channel information for identifying a channel number of the service, and information for acquisition of the second signaling information,
wherein the channel information includes a major channel number and a minor channel number of the service,
wherein the second signaling information is acquired based on the first signaling information,
wherein the second signaling information includes Internet Protocol (IP) address information for accessing of at least one IP packet delivering the service data,
wherein the at least one IP packet is included in a payload of a data packet, and
wherein a header of the data packet includes a pointer field which represents start position information related to the payload;
a first processor to acquire the at least one IP packet based on the first signaling information and the second signaling information; and
a second processor to provide the service to a user by processing the service data delivered in the acquired at least one IP packet.

2. A method of processing a broadcast signal in a receiver, the method comprising:
receiving the broadcast signal including service data of a service and signaling information for acquisition of the service;
demodulating the service data and the signaling information;
decoding the demodulated signaling information,
wherein the signaling information includes first signaling information and second signaling information,
wherein the first signaling information includes type information for identifying a type of the service, channel information for identifying a channel number of the service, and information for acquisition of the second signaling information,
wherein the channel information includes a major channel number and a minor channel number of the service,
wherein the second signaling information is acquired based on the first signaling information,
wherein the second signaling information includes Internet Protocol (IP) address information for accessing of at least one IP packet delivering the service data,
wherein the at least one IP packet is included in a payload of a data packet, and
wherein a header of the data packet includes a pointer field which represents start position information related to the payload;
acquiring the at least one IP packet based on the first signaling information and the second signaling information; and
providing the service to a user by processing the service data delivered in the acquired at least one IP packet.
