Embodiment Construction

[0036] Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like components throughout. The embodiments are described below in order to explain the present invention by referring to the figures.

[0037] image 3 is a block diagram showing the structure of an apparatus 300 for generating a dual transport stream according to an embodiment of the present invention. refer to image 3 , the device 300 for generating dual transport streams includes: a replicator 310 , a multiplexer 320 , an erasure encoder 350 , a Reed-Solomon (RS) encoder 330 and an interleaver 340 .

[0038] The erasure encoder 350 performs erasure encoding by receiving a turbo stream from an external source and removing noise from the turbo stream. The turbo stream may be received from an external module, such as a broadcast camera, or a different internal module, such as a compres...

Abstract

An apparatus to generate a dual transport stream including a duplicator that receives a turbo stream and that provides a parity insertion region for the turbo stream, and a multiplexer that receives a normal stream and that multiplexes the turbo stream processed by the duplicator and the normal stream to generate the dual transport stream. The duplicator provides the parity insertion region using a 1 / 2-rate conversion method or 1 / 4-rate conversion method. Only the turbo stream is detected prior to the transmission of the dual transport stream, and the parity is inserted into the parity insertion region so that the turbo stream can be robustly processed.

Description

technical field [0001] Various aspects of the present invention relate to a device for generating a dual transport stream including a normal stream and a turbo stream and a method thereof, and more particularly, to such a device for generating a dual transport stream including a normal stream and a turbo stream and a method thereof, the Apparatus and method for improving digital broadcasting performance by generating dual transport streams including normal streams and robustly processed turbo streams to improve Advanced Television Systems Committee (ATSC) Vestigial Sideband (VSB) as an American-style digital terrestrial broadcasting system system reception performance. Background technique [0002] The ATSC VSB system, which is an American-style digital terrestrial broadcasting system, is a signal carrier type broadcasting system, and it uses a field synchronization signal in units of 312 segments. Therefore, its reception performance is not good in poor channels, specifica...
