摘要： A method and an apparatus for receiving a broadcasting signal through a digital multimedia broadcasting network are provided to improve sensitivity of an OFDM receiver by removing an IFFT(Inverse Fast Fourier Transform) unit in the OFDM(Orthogonal Frequency Division Multiplexing) receiver. An apparatus for receiving a broadcasting signal through a digital multimedia broadcasting network includes a correlation value generator(44), a frame synchronization estimator(45), a gain estimator(46), and a symbol timing offset unit(47). The correlation value generator correlates a synchronization signal, which is included in a time domain reception signal, with a reference signal, and generates a correlation value in the time domain. The frame synchronization estimator compares the time domain correlation value with a reference value. The gain estimator determines a gain based on the time domain correlation value. The symbol timing offset unit detects a sample index of the correlation value with the determined gain.

摘要： An apparatus and a method for estimating a frequency offset improve reception performance of a mobile communication system and reduce complexity of the system by estimating interval of a subcarrier up to integral number or prime number times. A first correlative value is calculated by correlating the received signal with a signal of a first block corresponding to a part of a protective section of a reference symbol included in the received signal. A second correlative value is calculated by correlating the received signal with a signal of a second block corresponding to a part of a protective section. The first correlative value is time-delayed(S540). The frequency offset is estimated by using the delayed first and second correlative values.

A target-specified command link is inserted in a broadcasting editing process and broadcasting including the link is broadcasted(S10), and a broadcasting reception terminal receives the broadcasting, and the link is displayed in a screen by using an object such as a button or a character(S20). Activated information among the links displayed in the screen is transferred to a server or a command pointed by the broadcasting reception terminal is executed in the server(S30). The information transferred to the server or an execution result of the server is reflected on a broadcasting production process(S40). The target-specified command uses an ARS(Automatic Response Service), SMS(Short Message Service), server, or client command type depending on the used server or service type.

摘要： A method for providing and extracting link information by using an FIC(Fast Information Channel) is provided to offer and extract the link information such as a URL(Uniform Resource Locator) and a phone number without an additional device in a terrestrial DMB(Digital Multimedia Broadcasting) system. An ensemble multiplexer assigns a link flag to a link flag region(600). The ensemble multiplexer sets a link type in a link type region(602). The ensemble multiplexer inserts link information into a character region(604). The ensemble multiplexer compares the currently inserted link information with previously inserted link information and judges whether the link information is changed(606). If the link information is changed, the ensemble multiplexer changes a link version number of a version number region(608). If the link information is not changed, the ensemble multiplexer inserts a current part number of the currently inserted link information into a current part number region, and inserts the last part number of the currently inserted link information into the last part number region(610).
