JVC’s LT-37X987 and LT-32X987 High Definition LCD TVs are 720p (1366 x 768) high definition with a high contrast ratio of 800:1, a response time of 8msec and a wide viewing angle of 178º. Both models come with a built-in ATSC tuner and Clear QAM. They are also VESA Compliant for wall mounting

JVC’s Clear Motion Drive II

JVC’s LT-37X987 and LT-32X987 HD LCD TVs come with the second generation of JVC’s Clear Motion Drive (CMD) namely Clear Motion Drive II. The technology was developed by JVC to reduce blurring of moving images. To do this Cler Motion Drive uses a frame doubling driver and motion interpolation. When motion is detected in images, CMD II doubles the frame rate inserting an interpolated frame between originals giving a smoother progression and reducing blurring.

JVC confirmed improvement of moving images with CMD measuring the Moving Picture Response Time (MPRT) which is designed to quantify the visual perception of moving images across an LCD screen. Their research showed that MPRT was significantly higher (less blurring) at 120Hz (with interpolation) than 60Hz. JVC also maintain that the interpolated frame maintains image brightness.

First generation Clear Motion Drive only detected horizontal motion. CMD II detects image data from more than 8,000 dots in a frame to create a pixel and calculate the movement from one frame to the next. This process is repeated for all two million pixels in a frame (19.2 trillion dots evaluated per second) to interpolate movement in any direction. As one can image this requires some serious video processing power which reveals the logic behind use of the JVC’s fifth generation D.I.S.T. (Digital Image Scaling Technology) engine on the JVC-exclusive 32-bit Genessa chip.

Genessa chip

JVC’s Genessa chip, a 32-bit CPU processor, provides all image processing, noise reduction and color management technologies. From every source, D.I.S.T. (Digital Image Scaling Technology), onboard the GENESSA chip detects and up-scales the data (SD and HD) to display at full native resolution.

Gamma Control

Another of JVC’s video processing technologies on their GENESSA chip is their Motion Adaptive Dynamic Gamma algorithm. The algorithm detects areas of darker data, even in motion preserving the tonal details and graduations in those areas so that they remain rich with detail and never appear muddied.

5 Point Color Management System

JVC’s 5 Point Color Management System algorithm compensates for potential color range limitations with a pin-point sampling process that tells the GENESSA chip which colors need to be softened and which colors toned down. It anticipates which colors typically interfere with others and proactively preventing them from doing so.

JVC’s Noise Reduction Technology

Noise reduction an important factor in producing a good picture as High Definition TV magnifies picture distortions. JVC have developed a suite of noise reduction technologies including:

• Digital Video Noise Reduction to detect and stabilize digital video noise and reduce any graininess.
• A 3D Y/C Digital Comb Filter w/Cross Color Eliminator to detect and reduce embedded dot and color interference from digital broadcast and component signals for crystal clear images
• Natural Cinema (3-2 Pull Down) Technology which is an edge smoothing circuit that samples and compensates for the jagged edges commonly found in videos that were converted from film.
• Black Level Expansion

Audio

Features of JVC’s audio package include:

• 20W total audio power – 10-watts-per-channel amplifier
• A.H.S. (Advanced Hyper Surround) for creating the illusion of a 3D sound field without the need for a separate surround sound system
• Smart Sound for maintaining a constant volume level between program changes
• Vocal Enhancement
• Parametric Equalizer for optimal adjustment and balanced sound
• MaxxBass for maximum bass response and a bass reflex box to maximize the sound

Preset Modes

The JVC LCD’s have five video status modes (standard, game, theatre, dynamic, TheaterPro and D6500K) to provide quick select optimization for different viewing environments and video sources.

There are nine preset video aspect modes to find the best presentation mode for a particular video source: Full Native HD, Cinema Zoom, Panorama Zoom, Full HD, Slim, Cinema, Panorama, Full and Regular modes.
