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

1 - 8 . (canceled)

9 . A method for transmitting broadcast signals, the method comprising:
encoding broadcast data using a specific code rate; encoding signaling information including transmission parameters, 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 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 adjacent data units that include the known data.

10 . The method of claim 9 , wherein:
the signaling information further includes information specifying a number of broadcast data included in the data frames.

11 . The method of claim 9 , wherein the signaling information further includes version information indicating a version of a service acquisition data.

12 . An apparatus for transmitting broadcast signals, the apparatus comprising:
an encoder to encode broadcast data using a specific code rate; a signaling encoder configured to encode signaling information including transmission parameters, 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 adjacent data units that include the known data.

13 . The apparatus of claim 12 , wherein:
the signaling information further includes information specifying a number of broadcast data included in the data frames.

14 . The apparatus of claim 12 , wherein the signaling information further includes version information indicating a version of a service acquisition data.
