Subwoofer Designed to improve ultra low frequency with about 150Hz. There are active type that is built with a built-in amplifier and passive type that is required to connect an additional amplifier to it.

Mono Audio signals are produced through a single channel. It is difficult to experience a spectacular sound since audio signals are reproduced with a single speaker.

Stereo Audio signals are produced through two channels. A spectacular sound is reproduced with two separated speakers.

Widescreen Term given to picture displays with a wider aspect ratio than NTSC 4:3. Digital HDTV is 16:9 widescreen. Most motion pictures also have a widescreen aspect ratio, some even wider than 16:9.

Panorama screen Refers to a screen whose distortion due to the screen size has been calibrated.

External source Refers source signals that come from other external devices such as a VCR, camcorder and DVD player, etc. than a TV set.

MTS A bilingual service provided when an overseas film, foreign drama or overseas news, etc. is aired. You can select one of two choices: mother tongue and foreign language. Or you can listen to both languages at the same time.

DVI Digital Visual Interface is a specification for digital signals. This interface using TMDS transmission reduces the loss of signal, allowing to enjoy a clear and crisp image.

HDMI HDMI (High-Definition Multimedia Interface) is the first and only industry-supported, uncompressed, all-digital audio/video interface.

HDMI provides an interface between any audio/video source, such as a set-top box, DVD player, or A/V receiver and an audio and/or video monitor, such as a digital television (DTV), over a single cable.

Virtual channels There is a new numbering system for DTV channels. The system, called the “DTV virtual channels,”gives a number for each DTV program service, and almost always uses the analog NTSC channel number as the first number for that station. The use of virtual channels allows stations to use the same channel number “brand” for both NTSC and DTV. The printed listing services have not yet changed their format to show only the DTV virtual channel numbering system.So in the example, the station is using RF Channel 38 for DTV and is transmitting DTV programs with virtual channel numbers 15.n. The 15.n is short hand for 15.1, and 15.2 and 15.3, etc., as there can be more than one DTV program lineup from the station. So, 15.1 is the first DTV program lineup, 15.2 is the second, 15.3 is the third.Some DTV stations may have only one virtual channel, others perhaps as many as six.Transmitting HDTV on one of the channels usually means few other channels are on the air at that time as the HDTV takes most of the DTV channel capacity.
