DIGITAL BROADCASTING TRANSMISSION AND RECEPTION DEVICES AND METHODS THEREOF |
摘要 |
<p>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.</p> |
