DIGITAL BROADCAST TRANSMITTER AND DIGITAL BROADCAST RECEIVER, AND METHOD FOR PROCESSING STREAMS THEREOF

摘要

Disclosed is a digital broadcast transmitter. The transmitter of the present invention comprises a MUX unit and an exciter unit, which construct streams containing first service data and second service data that are different from each other. The exciter unit interleaves streams such that the first service data has a first body, a first head and a first tail, the second service data has a second body, a second head and a second tail, and the first head or the first tail is engaged with the second head or the second tail, at the interface between the first service data and the second service data, wherein at least a portion of the second service data is LDPC-coded or turbo-coded, and the rest of the second service data is TCM-coded.
