Method for sending signal in digital broadcast system, involves producing transmission frame based on data piece packet and signaling packet, and processing and sending transmission frame with transmission signal

摘要

The method involves producing a data piece packet (S100) by processing and optional scrambling a data stream. A signaling signal that comprises modulation and channel encoding in a physical layer related to a broadcast data stream, is produced. A representation is made whether data are scrambled. A signaling packet is produced (S110) by processing the signaling signal. A transmission frame is produced (S120) based on the data piece packet and the signaling packet. The transmission frame are processed and sent (S130) with a transmission signal. An independent claim is also included for a transmission apparatus.
