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.

A transmission stream (TS) generating apparatus includes an adaptor which receives general data and generates a stream having a plurality of packets, and which provides adaptive field in some of the plurality of packets, and an inserter which inserts additional data into all the payload areas of some of the plurality of packets that are not provided with the adaptive fields. Because additional data is transmitted, without requiring adaptive field header in certain packet, a data transmission rate is increased.

A dual transmission stream generating device includes an adaptor to receive a normal stream and to generate an adaptation field in an area of a packet of the normal stream; and a stuffer to generate a packet for a dual transmission stream by stuffing a turbo stream into the adaptation field. Accordingly, the turbo stream and the normal stream can be transmitted efficiently by the generation of the dual transmission stream in various constructions.

A method of processing a digital broadcasting signal includes generating a transport stream including a plurality of transport packets; selecting one of the transport packets as a starting packet to be mapped into a first data segment of an encoded data frame; and constructing deterministic data frames in the transport stream beginning with the starting packet; wherein at least one of the 52 transport packets does not have an adaptation field; wherein all remaining ones of the 52 transport packets do have an adaptation field; and wherein the at least one transport packet that does not have an adaptation field is provided at a fixed location in each of the slices.
摘要:
A trellis encoder for trellis encoding a dual transmission stream. A first multiplexer selectively outputs one of a predetermined first bit of the dual transmission stream and a value stored in a first memory according to an external control signal. A first adder adds the value output from the first multiplexer to the value stored in the first memory, outputs the added value, and stores the added value in the first memory. A second multiplexer selectively outputs one of a predetermined second bit of the dual transmission stream and a value stored in a second memory according to the external control signal. A second adder adds the value output from the second multiplexer to the value stored in the second memory and stores the added value in a third memory. Thus, an initialization is effectively performed before trellis encoding is performed.
