What is the PSP?
The PSP (PlayStation Portable), is Sony Computer
Entertainment's debut entry into the portable gaming
market, and potential competitor to Nintendo's long-running
Game Boy franchise. The unit plays disc-based videogames,
and also has the capacity to play digital video
and audio, as well as make use of other technologies
via its USB 2.0 interface and Memory Stick port.
Its wireless capabilities will allow free nearby
Link Play as well as distance online play with a
proper wireless network available.

PSP comes in a black color, with a 16:9
widescreen TFT LCD centered in a sleek ergonomic
design with a high-quality finish that fits
comfortably in the hands. The dimensions
are 170mm x 74mm x 23mm with a weight of
260g. PSP features a high-quality TFT LCD
that displays full color (16.77 million
colors) on a 480 x 272 pixel high-resolution
screen. It also comes complete with the
basic functions of a portable player such
as built-in stereo speakers, exterior headphone
connector, brightness control and sound
mode selection. Keys and controls inherit
the same operability of PlayStation®
and PlayStation 2, familiar to fans all
over the world.
PSP also comes equipped with diverse input/output
connectors such as USB 2.0, and 802.11b
(Wi-Fi) wireless LAN, providing connectivity
to various devices in the home and to the
wireless network outside. The world of gaming
is further enhanced by enabling users to
enjoy online gaming, or by connecting multiple
PSPs to each other, directly via the wireless
network. In addition, software and data
can be downloaded through a USB or wireless
network onto Memory Stick™ PRO Duo.
All of these features can be enjoyed on
one single system.
PSP adopts a small but high-capacity optical
medium UMD™ (Universal Media Disc),
enabling game software, rich with full-motion
video and other forms of digital entertainment
content, to be stored. The newly developed
UMD, the next-generation compact storage
media, is only 60mm in diameter but can
store up to 1.8GB of digital data. A broad
range of digital entertainment content such
as music video clips, movies and sports
programs can be provided on UMD. To protect
this entertainment content, a robust copyright
protection system has been developed which
utilizes a combination of a unique disc
ID, a 128 bit AES encryption keys for the
media, and individual ID for each PSP hardware
unit.
SCEI intends to aggressively promote PSP
and UMD as the new handheld entertainment
platform for the coming era.
