    摘要: Digital broadcasting transmission and reception devices and methods thereof are provided. The digital broadcasting transmission device includes a randomizer which randomizes a dual transport stream including a normal stream and a robust stream, a supplementary reference signal inserter which inserts a certain supplementary reference signal into a stuffing region included in the randomized dual transport stream, a Reed-Solomon (RS) encoder which adds a parity into a parity region included in the dual transport stream, a robust processor which configures a new dual transport stream by convolution-encoding the robust stream among the dual transport stream, an interleaver which interleaves the configured dual transport stream, a trellis encoder which trellis-encode the interleaved dual transport stream, and a modulator which transmits the trellis-encoded dual transport stream. Accordingly, a sub-channel can be provided in which the robust data and the supplementary reference signal will be transmitted.

    摘要: A digital broadcasting transmission and/or reception system having an improved reception performance and a signal-processing method thereof. A digital broadcasting transmitter comprises a TRS encoder for to TRS-encode an MPEG-2 transmission stream having null data for inserting an SRS data and a TRS parity at predetermined positions, randomizer to input and randomize data stream from the TRS encoder, a SRS exchanger to replace the null data for inserting the SRS data to the known data, and an encoder for encoding a data streams to which the Known data is inserted. Accordingly, the present invention detects the known data from a signal received from a reception side and uses the detected known data for synchronization and equalization and further uses the TRS parity for correcting error of the received signal, so that the digital broadcasting reception performance can be improved at poor multipath channels.

    摘要: A digital broadcast transmitting system and a signal processing method thereof that improves the receiving performance of the system. A digital broadcast transmitter includes a randomizer to receive and randomize a transport stream into a specified position of which stuff bytes are inserted, a replacement sequence generator to generate known data including a predefined sequence, a stuff-byte exchange unit to insert the known data into the specified position of the transport stream into which stuff bytes are inserted, an encoder to encode the transport stream output from the stuff-byte exchange unit for an error correction, and a transmission unit to modulate the encoded transport stream, RF-convert the modulated transport stream and transmit the RF-converted data. The digital broadcast receiving performance is improved even in an inferior multi-path channel by detecting the known data from the received transmission and using the known data for synchronization and equalization.
