MPEG-4 TECHNOLOGY
LG’s new 42PX8DC flat-panel HDTV Plasma incorpo-
rates the next-generation digital video compression
technology, MPEG-4 (Moving Picture Experts Group)
H.264, that enhances performance and simplicity for
venues delivering satellite high-definition program-
ming. This technology is the standard for compatibili-
ty with the more than 150 national HD channels and
1,500 local broadcast HD and digital channels being
launched by DIRECTV.
The advanced coding system enables delivery of many
more HD channels in the same frequency bandwidth
as before. Integrated MPEG-4 HDTVs support the
industry’s deployment of DIRECTV-delivered HD
content, while setting the stage for the longer-term
implementation of MPEG-4 by other satellite opera-
tors, cable companies, telcos and broadcasters. Since
MPEG-4 technology is built-in to these sets, an exter-
nal box* is not required to be used with HD content
providers who adapt to using this new technology.
*Certain functions, such as Pay-per-view, may require a set-top-box.
PRO:IDIOM
™
DIGITAL RIGHTS MANAGEMENT SYSTEM
The Pro:Idiom system’s high-quality security unlocks
access to premium content availability to help assure
rapid, broad deployment of HDTV and other high-
value digital content. Pro:Idiom has been designed
specifically for industries that use satellite-delivered
pay TV content or video-on-demand (VOD) services
and as such, could result in lower costs, and reduced
maintenance. This system is the leading DRM system
for the hospitality market, embraced by content pro-
viders for both of these key programming sources. By
using this embedded approach, security is enhanced,
making it virtually impossible for “customers” to tam-
per with or remove needed components.

LG’s exclusive XD Engine
®
takes the low resolution of analog signals to near HD levels
by improving brightness, contrast, detail and enhancing color as well as reducing signal
noise. This total solution results in cinema-like high resolution images.
The minimum black level f
of an image is automatically
detected and adjusted according to brightness
.
Using the noise f filter inside the X
is ana

ed for temporal and spat
MPEG noise.
At a blazingly ffast 370 million pixels per second, the
processor uses a histogram ana
