AVL characteristic

Most of broadcasting station has different modulation ratio. Especially, in case of CATV or BSTV broadcast system, the difference of modulation ratio is more serious than normal system. Whenever customer change the channel, volume level should be also adjusted again. AVL functi on makes uniform sound-output, independently of various modulation ra tio. AVL function can solve upper inconvenie nce of customer’s needless operation.So, it’s very power ful an d us eful function for customer. AVL function applied to MC-00AA chassis can make uniform sound-output level ( 54% modulation ratio) from 30% under-modulation to 300% over-modulation ratio. AVL modulation ratio is 54%, it’s base on 54% modulation ratio.

The black stretch circuit electronically makes the dark parts of the picture truly black and significantly clears up the difference between the brightest white and the deepest black on the picture, thereby creating extra-high contrast which results in outstanding image quality

This is the brightness of the display. The higher the figure, the brighter the display. This function adjusts the average level of the luminance signal in video signals so it is possible to make the background of the pict ure br i g ht er

LCD is different from the conventional CRT in that the colour temperature changes with the input brightness level. In order to compensate for this disadvantage, LG’s own algorithm was applied to create a CCT almost the same as that of a CRT

Digital Eye, the core of advanced integrated circuit (IC) with a digital processor developed with LG’s own technology to process the digital signal and to create optimized screen images

The Digital Index displays the current operation status of your TV in a separate display below the screen for your convenience

Digital Motion Compensation uses these images in digital memory to estimate motion and cre ate a new field, to be inserted into the repeated field in 100Hz. A simple non-motion compensated scan rate conversion repeats previous motion phase and causes a motion blurring on 100Hz output dependent on motion speed. With motion compensation intermediate motion phase is calculated and the ideal curve is obtained and no motion blurring occurs

Digital Motion Compensation uses these images in digital m emory to estimate motion and create a new field, to be inserted into the repeated field in 100Hz

Feel like you’re in a real theatre. This is the same system used to create incredible sound and realism in many movie theatres. This system creates a fourth audio channel in the movie or broadcast by adding a centre channel. This also provides special active circuits that “steer” the special effects sounds around the room with much more accuracy and realism than Do lby Virtual surround

Just enjoy your TV screen as PC monitor with high resolution pictures. High resolution (WXGA) PC display and TV in one set is possible without additional equipment like encoder or decoder

Can enjoy digital image on highest resolution without any image losses through DV digital RGB Jack

In single focus TV’s, the focus is on the centre of the TV screen so peripheral screen clarity diminishes as the CPT gets larger and flatter. But the truly flat LG Flatron with Dynamic Focus, not only focuses on the centre but also the peripherals to ensure clear images throughout the entire screen

Dynamic SVM (Scanning Velocity Modulation) controls the scanning of an electron beam to enhance the sharpness of image edges. Scanning speed changes during the t ra nsition in highly defined black to white and sharper vertical lines

This helps raise brightness and contrast and improves colour reproduction. In proportion to the increase of attached pigments on phosphors, colour purity and contrast are increased by reducing the reflectivity of powder and more darkened powder colours. These types of pigments attached on phosphors play an important role as an optical filter, resulting in the reflection of the true colour and absorption of other colours

The FLOF is the upgraded version of WST (World Standard Teletext). This FLOF system adopts coloured section keys at the bottom of the TV screen when a viewer watches teletext. Now you can select the section that you want to watch by simply pressing a coloured button on the remote control instead of pressing a number

The Horizontal Flip function reverses the left and right side of the projected image. Use this function when a projector shoots from behind a screen and the screen is viewed from the opposite side. The Vertical Flip function reverses the upper and lower side of the projected image. Use this function when you mount a projector on the ceiling because the projected image is turned upside down

Hyper-

Keystone

Correction

The number of television broadcasts is expanded rapidly. To satisfy the customers who want a wider programme range, our TV adopts the tuner, which can receive CATV broadcasts, including hyper-broadband

What is Keystone Correction? Keystone is when your image appears wider at the top or bottom because the projector is positioned somewhere other than the centre of the screen. Keystone Correction corrects this rectangular distortion

With the adoption of a stereo amplifier of 2 Carrier and NICAM, you can enjoy advanced digital stereo sound equivalent to that of a compact disk at any time and any place where available

To display TV programmes, VCR or other external appliances at the same time, it adopts 4 or 9 sub-screens at the bottom of the TV screen. It allows users to watch two or more programmes simultaneously with various fun c tions such as Size, Swap, Still, Position, 4-screen and 9-screen. In addition, it compresses the main screen and then displays the sub-screens outside the main screen so that users can enjoy the whole main screen and sub screens at the same time

NICAM is another stereo system for reproducing the clear sound equivalent to that of a compact disc

You can watch a laser disk recorded in the NTSC System on a TV with a PAL system (with NTSC

3.58) through A/V terminals. (Colour carrier is not converted into the PAL mode)

The surface of the standard TV CPT has a round surface that reflects, reducing screen clarity and increasing eye fatigue. LG’s Flatron CPT is not only truly flat, but thanks to its dark and anti-coating, reflection is minimised to provide a clear screen and reduce eye fatigue even after long-term viewing

Turbo Picture function always provides the highest screen quality. With a touch of a button, the screen’s brightness, contrast and sharpness are automatically adjusted to provide viewers with the best and clearest picture quality. Turbo Sound has Digital Audio Surround System (DASS) with 2 amplifiers, 4 channels and 6 speakers. Combined with the Turbo Sound, a touch of a button is enough to enjoy the energetic and powerful sound provided by DASS. LG’s Turbo Sound provides you with powerful sound that brings the screen image to life. Turbo Booster developed by LG, the wo rld’ first, is an automatic image amplifier that enhances reception in the areas with weaker TV signals. At the same time, it eliminates unnecessary noise to provide the best picture images to the viewers.The system also improves teletext, colour, sound and picture play capabilities in areas with weaker signals
