Format method of transport stream packet for improve receiving performance and digital broadcasting transmission and reception apparatus and method thereof

摘要

The digital broadcasting method for configuring a transport stream packet and the digital broadcasting transmitter, and a method of signal processing for the reception performance enhancement is proposed. According to the invention, known for the synchronization (Known) additional reference signal (SRS: Supplementary Reference Sequence) configuring the transport stream packet including a stuffing area (stuffing region) for data insertion, and random a packet including the stuffing region granulation to, in addition to the stuffing region of the randomized packet reference signal (SRS) to insert the data, and the additional reference signals (SRS) and data is added parity for error correction to the inserted packet. In addition, by performing the interleaving for the parity-added packet, and performs trellis encoding on the interleaved packet, a trellis-encoded segment sync signal to the packet (Segment sync) and a field synchronization signal (Field sync) and then, it modulates the packet by inserting the sync signals inserted into the VSB and then transmits the RF conversion. ; Additional reference signal (SRS), the stuffing area, ATSC VSB, compatibility parity
