Problems solved by technology

[0013] However, figure 1 The U.S. type digital terrestrial broadcasting system has the problem that although the system transmits double streams produced by adding robust data to normal data, poor reception in multipath channels can hardly be improved in the transmission of existing normal data performance

Embodiment Construction

[0047] Reference will now be made in detail to the present embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like numerals refer to like parts throughout. The embodiments are described below in order to explain the present invention by referring to the figures.

[0048] image 3 is a block diagram showing the configuration of an apparatus 300 for generating dual transport streams according to an embodiment of the present invention

[0049] refer to image 3 , the device 300 for generating dual transport streams includes a duplicator 310 and a multiplexer 320 .

[0050] When the duplicator 310 receives the turbo stream, the duplicator 310 provides a parity insertion area in the turbo stream. The method of providing the parity insertion area will now be explained in more detail. Each byte that is a constituent unit of the turbo stream is divided into 2 or 4 bytes. The divided bytes are filled with partial bit value...

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] Aspects of the present invention relate to a device for generating dual transport streams including a normal stream and a turbo stream and a method thereof, and more particularly, to a device for generating dual transport streams including a normal stream and a turbo stream and a method thereof, The apparatus and method are capable of improving reception of the Advanced Television Systems Committee (ATSC) Vestigial Sideband (VSB) system, which is an American type digital terrestrial broadcasting system, by generating dual transport streams including a normal stream and a turbo stream capable of robust processing performance, thereby improving digital broadcasting performance. Background technique [0002] The Advanced Television Systems Committee (ATSC) Vestigial Sideband (VSB) system, which is an American type digital terrestrial broadcasting system, is an information carrier type broadcasting system using a field synchronization signal having a unit ...
