| 发明名称 | Broadcast transmitter and method of processing broadcast service data for transmission | ||
| 摘要 | A method processing broadcast data in a broadcast transmitter is described. The method may include randomizing broadcast service data, encoding the randomized broadcast service data at a code rate of D/E. D<E, and D and E are integers equal to or greater than 1, respectively. The method further includes first interleaving the encoded broadcast service data, second interleaving the first-interleaved broadcast service data, encoding signaling data for signaling the broadcast service data, interleaving the encoded signaling data, modulating the first-interleaved broadcast service data and the interleaved signaling data, and transmitting the modulated data. The signaling data may include information for indicating the code rate. | ||

| 主权项 | 1. A method of processing broadcast service data in a broadcast transmitter, the method comprising: randomizing broadcast service data; encoding the randomized 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 encoded broadcast service data; second interleaving the first-interleaved broadcast service data; encoding signaling data for signaling the broadcast service data; interleaving the encoded signaling data; modulating the second-interleaved broadcast service data and the interleaved signaling data; and transmitting the modulated data, wherein the signaling data include information for indicating the code rate. | ||
