Abstract

A transmitting system and a method of transmitting digital broadcast signal are disclosed. The method of transmitting digital broadcast signal includes generating signaling data including a transmission parameter, wherein the transmission parameter includes a protocol version field identifying between a first transmission mode and a second transmission mode, forming a data group including mobile service data and the signaling data, forming mobile service data packets including the mobile service data and the signaling data in the data group, transmitting the digital broadcast signal including the data group.

First claim

What is claimed is:

1. A method for transmitting broadcast signals, the method comprising:
FEC (Forward Error Correction) encoding broadcast data for broadcast service;
encoding the FEC encoded broadcast data using a specific code rate;
encoding signaling information including transmission parameters and service acquisition data, the service acquisition data carrying cross-layer information to enable fast service acquisition and the transmission parameters including code rate information specifying the specific code rate;
generating data frames including the encoded broadcast data and the signaling information; and
transmitting the broadcast signals including the data frames,
wherein signaling information further includes information specifying a transmission mode,
wherein the data frames include a plurality of data units,
wherein each of the data units includes known data used for channel equalization at a receiver, and
wherein the signaling information further includes information specifying neighboring data units that include the known data.

2. The method of claim 1 , wherein:
the signaling information further includes information specifying a number of broadcast data included in the data frames; and
the number of the broadcast data is scalable.

3. The method of claim 1 , wherein the signaling information further includes version information indicating a version of the service acquisition data.

4. An apparatus for transmitting broadcast signals, the apparatus comprising:
a first encoder configured to FEC (Forward Error Correction) encode broadcast data for broadcast service;
a second encoder configured to encode the FEC encoded broadcast data using a specific code rate;
a signaling encoder configured to encode signaling information including transmission parameters service acquisition data, the service acquisition data carrying cross-layer information to enable fast service acquisition and the transmission parameters including code rate information specifying the specific code rate;
a generating unit configured to generate data frames including the encoded broadcast data and the signaling information; and
a transmission unit configured to transmit the broadcast signals including the data frames,
wherein the signaling information further includes information specifying a transmission mode,
wherein the data frames include a plurality of data units,
wherein each of the data units includes known data used for channel equalization at a receiver, and
wherein the signaling information further includes information specifying neighboring data units that include the known data.

5. The apparatus of claim 4 , wherein:
the signaling information further includes information specifying a number of broadcast data included in the data frames; and
the number of the broadcast data is scalable.

6. The apparatus of claim 4 , wherein the signaling information further includes version information indicating a version of the service acquisition data.
