Problems solved by technology

Therefore, in a poor channel environment, the receiving performance of the digital broadcast receiving system will be degraded
In particular, reception performance may be further degraded when using VSB transmission mode to transmit mobile service data due to the higher requirements for higher immunity to channel variations and noise when using portable and / or mobile broadcast receivers

Abstract

A transceiving system and a data processing method are provided to signal mapping information between an ensemble and a mobile service through an FIC chunk and divide the FIC chunk by an FIC segment unit to transmit the FIC chunk through an FIC, thereby enabling the receiving system to quickly obtain a service. CONSTITUTION: An FIC(Fast Information Channel) segment parser outputs a payload of a corresponding FIC segment to an FIC chunk parser according to an analysis result of the header of each FIC segment. The FIC chunk parser restores an FIC chunk data structure from the FIC segment payloads. The FIC chunk parser extracts signaling information to obtain a service. A service manager(122) receives a current RS frame through SG boot strapping information, and receives a corresponding SG from one of a tuner(111), another broadcasting network interface, and an interactive network interface.

Description

technical field [0001] The present invention relates to a transmission system for transmitting broadcast data, a reception system (or receiver) for receiving data transmitted by the transmission system, and a method for processing data in the transmission system and the reception system (or receiver) method. Background technique [0002] A vestigial sideband (VSB: vestigial sideband) transmission mode adopted as a digital broadcasting standard in North America and Korea is a system using a single carrier method. Therefore, in a poor channel environment, the receiving performance of the digital broadcast receiving system will be degraded. In particular, reception performance may be further degraded when using VSB transmission mode to transmit mobile service data due to the higher requirements for higher immunity to channel variations and noise when using portable and / or mobile broadcast receivers . Contents of the invention [0003] technical problem [0004] Accordingl...
