Abstract: 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).

Abstract: An apparatus and a method for processing data in a multi-stream STB(Set-Top Box) are provided to select a TS(Transport Stream) corresponding to a broadcast program selected by a viewer and transmit only an MPEG2(Moving Picture Experts Group 2) TS corresponding to a paid program, which needs restrictive transmission, to a cable card, thereby preventing unnecessary data transmission and the unnecessary driving of the cable card in interface between the multi-stream STB and the cable card. A method for processing data in a multi-stream STB comprises the following steps of: allowing a terminal central processing unit to extract program information from SI(Service Information) whenever a viewer selects a new program(401,402); receiving a message related to the program(403); filtering the MPEG2 TS of a program which the message indicates(404); determining whether it is necessary to receive the MPEG2 TS restrictively(405); transmitting a TS stream, which needs restrictive transmission, to a cable card(406); and reproducing a TS stream having no need of restrictive transmission(407).

Abstract: An apparatus and a method for estimating a channel in a receiving system based on hierarchical modulation are provided to estimate the channel without a training signal by estimating the channel through applying a weighted value to a high priority transmission signal and a low priority transmission signal. An apparatus for estimating a channel in a receiving system based on hierarchical modulation includes a demodulating unit(21), a channel equalizing unit(22), a transmission signal estimating unit(23), and a channel estimating unit(24). The demodulating unit transforms a received signal to a signal of a frequency area. The channel equalizing unit performs channel equalizing by using the signal of the frequency area demodulated by the channel equalizing unit and a previously estimated channel. The channel estimating unit estimates the signal of the frequency area demodulated by the demodulating unit, and a high priority transmission signal and a low priority transmission signal. The channel estimating unit estimates the channel by applying weighted values to the high priority transmission signal and the low priority transmission signal estimated by the transmission signal estimating unit.
