Abstract

A broadcast transmitter and a method of processing broadcast data in the broadcast transmitter are disclosed. The method includes the steps of performing RS encoding and CRC encoding on mobile service data to build RS frames belonging to an ensemble, wherein each of the RS frames are mapped into data groups, wherein each of the data groups comprises known data sequences and a portion of FIC data including information for rapid mobile service acquisition, wherein the information for rapid mobile service acquisition includes transport stream identification information for identifying a mobile broadcast carrying a mobile service that includes the mobile service data and C/N indication information for indicating whether the FIC data are applicable to a current transmission frame or a next transmission frame, multiplexing data in the data groups and main service data, and transmitting a transmission frame including the multiplexed data.

First claim

The invention claimed is:

1. A method of processing data in a broadcast transmitter, the method comprising:
Forward Error Correction (FEC) encoding broadcast service data for a broadcast service;
forming first frames including the FEC-encoded broadcast service data; and
transmitting a second frame including data in the first frames,
wherein the second frame includes one or more first frames,
wherein the second frame includes first signaling information and second signaling information,
wherein at least one of the first signaling information or the second signaling information includes information to identify a broadcast service to be serviced by the broadcast service data,
wherein the broadcast service data includes first broadcast service data and second broadcast service data,
wherein both of the first broadcast service data and the second broadcast service data represent perceptually equivalent content, but the first broadcast service data is coded differently from the second broadcast service data, and
wherein the first signaling information further includes information for seamless switching between the first broadcast service data and the second broadcast service data while presenting the equivalent content,
wherein the second signaling information includes number information to specify a number of the first frames within the second frame.

2. The method of claim 1 , wherein the second frame further includes third signaling information, the third signaling information including information for fast acquisition of one or more services.

3. The method of claim 1 , wherein the at least one of the first signaling information or the second signaling information further includes Internet Protocol (IP) version information when the broadcast service data is an IP type.

4. The method of claim 1 , wherein the broadcast service data for one or more services are encoded with a same FEC code.

5. A broadcast transmitter for processing data, the broadcast transmitter comprising:
an encoder that Forward Error Correction (FEC) encodes broadcast service data;
a formatting device that forms first frames including the FEC-encoded broadcast service data; and
a transmitting device that transmits a second frame including data in the first frames,
wherein the second frame includes one or more first frames,
wherein the second frame further includes first signaling information and second signaling information,
wherein at least one of the first signaling information or the second signaling information includes information to identify a broadcast service to be serviced by the broadcast service data,
wherein the broadcast service data includes first broadcast service data and second broadcast service data,
wherein both of the first broadcast service data and the second broadcast service data represent perceptually equivalent content, but the first broadcast service data is coded differently from the second broadcast service data, and
wherein the first signaling information further includes information for seamless switching between the first broadcast service data and the second broadcast service data while presenting the equivalent content,
wherein the second signaling information includes number information to specify a number of the first frames within the second frame.

6. The broadcast transmitter of claim 5 , wherein the second frame further includes third signaling information, the third signaling information including information for fast acquisition of one or more services.

7. The broadcast transmitter of claim 5 , wherein the at least one of the first signaling information or the second signaling information further includes Internet Protocol (IP) version information when the broadcast service data is an IP type.

8. The broadcast transmitter of claim 5 , wherein the broadcast service data for one or more services are encoded with a same FEC code.
