Digital broadcasting system and method of processing data in digital broadcasting system
A digital broadcasting system and a data processing method are disclosed. A receiver receives a broadcast signal including mobile service data and main service data. A known data detector detects known data from the broadcast signal. An equalizer performs channel equalization on the mobile service data received by means of the detected known data. An RS frame decoder acquires an RS frame from the channel-equalized mobile service data. A management processor extracts a Generic Stream Encapsulation (GSE) packet from a GSE Base Band (BB) constructing one row of the RS frame, and calculates an IP datagram from the extracted GSE packet. A presentation processor displays broadcast data using data contained in the calculated IP datagram.
1. A method of processing broadcast data in a transmitter, the method comprising:
generating a baseband frame that includes a data packet that has a compressed header and includes service data;
encoding data of the baseband frame;
encoding first signaling data that include information to enable fast service acquisition;
encoding second signaling data that include transmission parameters; and
transmitting a broadcast signal including the encoded data, the encoded first signaling data and the encoded second signaling data,
wherein the first signaling data include information for locating where service layer signaling is carried, and
wherein the service layer signaling includes access information of the service data.
2. The method of claim 1 , wherein the second signaling data further include information to indicate a change in the first signaling data.
3. A transmitter for processing broadcast data, the transmitter comprising:
a generator that generates a baseband frame that includes a data packet that has a compressed header and includes service data;
an encoder that encodes data of the baseband frame and further encodes first signaling data including information to enable fast service acquisition and second signaling data including transmission parameters; and
a transmitting unit that transmits a broadcast signal including the encoded data, the encoded first signaling data and the encoded second signaling data,
wherein the first signaling data include information for locating where service layer signaling is carried, and
wherein the service layer signaling includes access information of the service data.
4. The transmitter of claim 3 , wherein the second signaling data further include information to indicate a change in the first signaling data.
