BROADCAST TRANSMITTER AND METHOD OF PROCESSING BROADCAST SERVICE DATA FOR TRANSMISSION |
| 摘要 |
A method is provided for processing broadcast data in a broadcast transmitter. Broadcast service data is randomized. The randomized broadcast service data is first-encoded to add parity data to the randomized broadcast service data. The first-encoded broadcast service data is second-encoded. The second-encoded broadcast service data is first interleaved. The first-interleaved broadcast service data is second-interleaved. Signaling data is encoded for signaling the broadcast service data. The encoded signaling data is third-interleaved. The third-interleaved signaling data is fourth interleaved. A frame is transmitted that is divided into a data region including the second-interleaved broadcast service data, a first signaling region including the fourth-interleaved signaling data and a second signaling region that includes at least one symbol that is used for synchronization and channel estimation. The frame includes known data. The encoded signaling data includes information for identifying the code rate and information related to the known data. |

1. A method of processing broadcast data in a broadcast transmitter, the method comprising:
randomizing broadcast service data; first encoding the randomized broadcast service data to add parity data to the randomized broadcast service data; second encoding the first-encoded broadcast service data at a code rate of D/E, wherein D<E, and wherein D and E are integers equal to or greater than 1, respectively; first interleaving the second-encoded broadcast service data; second interleaving the first-interleaved broadcast service data; encoding signaling data for signaling the broadcast service data; third interleaving the encoded signaling data; fourth interleaving the third-interleaved signaling data; and transmitting a frame, wherein the frame is divided into a data region including the second-interleaved broadcast service data and a first signaling region including the fourth-interleaved signaling data, wherein the frame includes known data, wherein the encoded signaling data includes information for identifying the code rate and information related to the known data, wherein the frame is further divided into a second signaling region that is located at a beginning of the frame, and wherein the second signaling region includes at least one symbol that is used for synchronization and channel estimation. |
