    摘要： A digital TV system for forwarding EAS information and a method thereof are provided. The digital TV system forwards the EAS information to an external device including a mobile phone. Accordingly, even if a user does not watch the TV or does something different from watching the TV, the user can easily obtain the EAS information through his/her own mobile phone and promptly cope with an emergency situation.

    摘要： A method of scanning channels in a digital television including (a) setting a starting frequency; (b) searching for a first available digital channel by searching a search frequency that is the starting frequency; adding a predetermined scan step to said search frequency if the first available channel is not found at the starting frequency, and adding additional predetermined scan steps to the search frequency until the first available channel is found if the first available channels is not found at the starting frequency plus the scan step; and (c) searching for a second available digital channel by searching at a first main frequency, which is the first available channel frequency plus a first predetermined bandwidth, wherein the step of searching for the second available digital channel includes searching at a plurality of scan steps around the first main frequency.

    摘要： Broadcast signal-receiving apparatus and a method filtering noise signals. The broadcast signal-receiving apparatus includes a tuner to convert an RF signal to a lower frequency signal to output an intermediate frequency (IF) signal, a filter to filter the IF signal to output a digital IF signal, and a controller to control the tuner to shift a frequency of the IF signal to a frequency band to remove the noise signals if the digital IF signal contains noise signals of a predetermined magnitude. Accordingly, the broadcast signal-receiving apparatus can filter the noise signals resulting from analog and digital broadcast signals adjacent to a digital broadcast signal on a channel selected for viewing.

    摘要： Automatic test equipment is capable of performing a high-speed test of semiconductor devices, with a low cost and high efficiency. The automatic test equipment (ATE) comprises: an ATE body configured to electrically test semiconductor devices; a field programmable gate array (FPGA) controlling drivers and comparators on the ATE; an accelerator connected to an output terminal of the FPGA and that doubles an operating frequency of the FPGA; and a decelerator connected to an output terminal of the FPGA and that converts an operating frequency of data transferred from the semiconductor device to the operating frequency of the FPGA.
