Sony's LF-X1 LocationFree TV puts the age
of mobile lifestyles and high-speed network connectivity at
your fingertips in the form of a portable, broadband
Internet-enabled LCD television system that you can use
virtually anywhere in the world. Weighing less than an
average laptop PC, the wireless LF-X1 consists of a
12.1-inch LCD TV with a standard 4:3 aspect ratio, 800 x 600
native pixel resolution, and an accompanying base station.
The base station houses most connection terminals, an NTSC
broadcast tuner, and a wireless transmitter. The monitor
runs on a supplied rechargeable lithium battery, while the
battery charger works on universal power (AC 100 to 240V)
for use in most countries.
The LocationFree TV is lightweight and easy to tote from
place to place.
Using Sony's first dual-band wireless system (2.4 and 5
GHz), the base station transmits video content to the
touch-panel screen--there's no mouse required. The set
delivers stable video and audio signals without interference
from other 2.4 GHz devices such as microwave ovens and
cordless phones. Internet and TV content arrives from the
base station by way of secured device authentication and
encryption technology, making the system perfect for
Internet surfing in Wi-Fi hotspots and via Ethernet ports
found in hotels, airports, and other locations.
The innovative system employs the IEEE 802.11a/g protocol
for a wide selection of transmission channels, and it
switches the channel automatically to minimize monitor
interference across a range of up to 100 feet from the base
station. The 802.11a/g standards support a higher bit rate
than the conventional 802.11b standard, helping the set
maintain stable, high-quality video images. The LocationFree
TV also uses advanced Quality of Service (QoS) technology,
which delivers extra bandwidth security for reliable
audio-video transmissions, even in high-traffic wireless
environments.
Faroudja's Directional Correlation Deinterlacing (DCDi) is a
video algorithm designed to eliminate the jagged edges along
diagonal image lines resulting from video interpolation.
DCDi monitors transitions in image edges and fills in the
gaps between frames.
The LF-X1 is a multitasking chameleon. It weighs around 5
pounds and includes angled-line correction circuitry for
smoothing out jagged lines; motion-adaptive I/P conversion
circuitry for improving fast-moving action scenes; and a
digital-audio amplifier for crisp sound with minimal
distortion. It also features picture-in-picture capability
and an audio-video input for connecting to a camcorder, game
console, DVD player, or other entertainment device.
The LocationFree TV autoselects the strongest wireless
signal so you get the best transmission wherever you're
watching.
When the base station and the wireless monitor are each
connected to the Internet through your existing ISP, you can
easily and quickly access the Web, exchange e-mail, and shop
online using the onscreen keyboard. The unit can also morph
into a digital photo album, displaying custom slide shows
from its built-in memory or from Memory Stick media, which
plugs into a dedicated flash-memory port.
Filling the role of an intuitive graphical user interface
(GUI), the onscreen universal remote and onscreen keyboard
heighten the LocationFree TV's uniqueness and versatility.
Sony's GUI simplifies navigation of all aspects of the set.
You can even use the screen itself as a remote to switch
from channel to channel or from function to function. (A USB
port facilitates hookup of an optional physical keyboard.)
The base station houses an Ethernet port for broadband
compatibility and two video inputs (S-video and
composite-video) for audio-video components and other
peripherals. There's also IR blaster for added control and
convenience and a USB port for connecting to an optional
dial-up modem.
