Benefits of technology

The system effectively transmits and receives multi-transport streams with various coding rates, enhancing reception quality and reducing power consumption in receiving devices by processing turbo streams in turbo units, thereby improving overall system efficiency.

Problems solved by technology

Therefore, reception degrades in the poor channel such as a Doppler fading channel.
However, a conventional digital broadcast system does not provide transmission and reception of dual TS including normal data and turbo data of various coding rates.

Abstract

A transport stream (TS) generating apparatus, a transmitting apparatus, a receiving apparatus, a digital broadcast system having the above, and a method thereof are provided. The digital broadcast system includes a transport stream (TS) generating apparatus which generates a multi transport stream (TS) by multiplexing a normal stream and a turbo stream having a variable coding rate, a transmitting apparatus which re-constructs the multi TS by processing the turbo stream, and transmits the re-constructed multi TS, and a receiving apparatus which receives the re-constructed multi TS, and decodes the normal stream and the turbo stream respectively, to recover normal data and turbo data. Accordingly, a multi TS, which includes normal stream and a turbo stream of various coding rates, can be transmitted and received efficiently.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of application Ser. No. 12 / 021,521 filed on Jan. 29, 2008, now pending which claims the benefit of Korean Application No. 2007-38947 filed Apr. 20, 2007, in the Korean Patent Office, the disclosures of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1.
