DIGITAL BROADCASTING SYSTEM AND METHOD OF PROCESSING DATA IN DIGITAL BROADCASTING SYSTEM

摘要

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:
encoding mobile service data of a path, the path carrying one or multiple services; first encoding first signaling data, wherein the first signaling data include information to enable fast service acquisition; second encoding the first-encoded first signaling data; first encoding second signaling data, wherein the second signaling data include information to identify the path; second encoding the first-encoded second signaling data; and transmitting a broadcast signal including the encoded mobile service data, the second-encoded first signaling data and the second-encoded second signaling data, wherein the mobile service data are included in a payload of a data packet having a header, the header being compressed.
