Multi-transport stream (TS) generating apparatus and method, and digital broadcasting transmission and reception apparatuses and methods

摘要

A multi-transport stream (TS) generating apparatus and method, and digital broadcasting transmission and reception apparatuses and method are provided. The multi-TS generating apparatus includes an adaptor to generate an adaptation field in some packets of a normal stream; an interleaver to interleave the normal stream; a turbo processor to turbo-code a plurality of turbo streams; a stuffer to generate a multi-TS by stuffing the plurality of the turbo streams into the adaptation field; and a deinterleaver to deinterleave the multi-TS. Accordingly, the plurality of the turbo streams can be transmitted far more easily.

主权项

1. A digital broadcasting reception apparatus, comprising:
a demodulator to demodulate input data comprising normal data and additional data; an equalizer to equalize the demodulated data; and a decoder to decode the additional data included in the equalized data; and a Reed-Solomon (RS) decoder to RS-decode the decoded additional data, wherein the decoder comprises:
a trellis decoder to receive and trellis decode the equalized data;a deinterleaver to deinterleave the trellis-decoded additional data without deinterleaving the normal data; andan outer decoder to convolutional decode the deinterleaved additional data.
