Embodiment Construction

[0018] Reference will now be made in detail to the various embodiments of the present general inventive concept, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like components. The embodiments are described below in order to explain the present general inventive concept by referring to the figures.

[0019] figure 2 is a block diagram illustrating a broadcast signal receiving device according to one embodiment of the present general inventive concept. Such as figure 2 As shown, the broadcast signal receiving apparatus includes an antenna 100 , a tuner 110 , a SAW filter 130 , an IF amplifier 140 , an IF signal processor 160 , a controller 180 and a channel storage unit 190 .

[0020] The tuner 110 converts an RF signal received through the antenna 100 into an intermediate frequency (IF) signal. That is, tuner 110 can receive RF signals for ATSC standard digital broadcasts and NTSC standard analog broadcasts, and by...

Abstract

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.

Description

technical field [0001] The general concept of the present invention relates to a broadcast signal receiving device and a method for filtering noise signals, and more particularly to a broadcast signal receiving device and a method for filtering noise signals introduced by analog and / or digital broadcast signals, the analog and / or the digital broadcast signal adjacent to the selected digital broadcast signal received on the channel selected for viewing. Background technique [0002] Digital TV systems compress, digitize, and transmit video and audio signals. Advances in digital signal processing and communication technologies have led to the development of broadcast signal receiving devices capable of receiving ATSC (Advanced Television Systems Committee) from digital broadcast signals, along with NTSC (National Television System Committee) standard analog broadcast signals. ) digital broadcast signal of the standard VSB (Vestigial Sideband) system. These analog and digital...
