## Abstract

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.
