1. A method for receiving a broadcast signal, the method comprising:
- receiving a broadcast signal carrying a transmission frame, wherein a collection of data groups is carried within specific time periods in the transmission frame, each of the data groups including known data sequences, signaling information and mobile service data, which comprise broadcast service data for a mobile broadcast system, wherein each of the data groups includes;
a first region in which the mobile service data is not multiplexed with main service data,a second region including a first data segment in which K bytes of the main service data are multiplexed with the mobile service data, anda third region including a second data segment in which M bytes of the main service data are multiplexed with the mobile service data, wherein K<
M,wherein the first region is positioned between two regions of the second region and the first and second regions are positioned between two regions of the third region in each of the data groups,wherein the collection of data groups carries the mobile service data encoded through a Reed-Solomon (RS) frame, and wherein the signaling information includes an RS code mode for the RS frame;
demodulating the received broadcast signal;
building the RS frame including the mobile service data in the data groups and decoding the RS frame according to the RS code mode;
extracting electronic program information about the mobile service data in the decoded RS frame; and
displaying the extracted electronic program information.

Abstract
A data transmission system for minimizing the number of errors during Tx/Rx times of digital data under mobile environments, and a data processing method for the same are disclosed. The system additionally codes digital data, and transmits the resultant coded data. As a result, the program information has a strong resistance to noise and channel variation, and can quickly cope with the rapid channel variation.
