The PSP (PlayStation Portable) system is the first truly integrated portable entertainment system designed to handle multiple applications – music, video, photo, internet, and wireless connectivity, with games as its key feature. The PSP system features an unmatched library of entertainment content, combining more than 135 games and more than 430 feature films, TV programs, and videos on UMD (universal media disc, developed by Sony specific to the PSP)from major studios and record labels, as well as downloadable content from the internet.
The PlayStation Portable can connect to a wireless network through Wi-Fi IEEE 802.11b. This allows two (or more) players with PlayStation portables to create a local, ad-hoc network for multiplayer gameplay, and also allows the a PSP user to connect to the internet via an internet-connected Wi-Fi router. By connecting to the internet, players can compete against other players also connected to the internet, or browse the web and download files to the Memory Stick via the built-in Access Co. NetFront browser.
The PlayStation Portable features a standard IrDA port located on the top left of the device. To date, the only games or applications to leverage this feature have been homebrew. This can be used to control many TVs as well as other iR devices.
The PlayStation Portable's main menu allows the user to configure the system for use across the Internet or an intranet via a wireless connection, known as infrastructure mode. The PlayStation Portable's menu can recognize protected and non-protected wireless networks within its range, and supports connecting to WEP and WPA encrypted networks.
Use of infrastructure networks in PlayStation Portable software began with a small number of titles at the U.S. launch, supporting online play.
Sony's LocationFree Player allows users to stream live television broadcasts (or other video content) to their PlayStation Portable, within their WiFi network, or remotely via the internet.
The RSS features allow the user to download video web feeds or listen to podcasts from websites. RSS or podcast content can be saved to the Memory Stick Duo. Audio content can be streamed and played live. Blogs however, are not supported.
Ad-hoc wireless networking allows for up to 16 PlayStation Portables within range to communicate directly to each other (typically for multi player gaming). One unit acts as the host for a game, which is available to other PlayStation Portable units within that system's range, and appears in a list when the client PlayStation Portable searches for available hosts. You can also use an Ad-Hoc network to send images from one PlayStation Portable to another by use of the "send" and "receive" functions that appear in the "PHOTO" menu.
Some titles for the PlayStation Portable support a feature dubbed "gamesharing", which facilitates a limited set of multi player features between two PlayStation Portables with only one copy of the game UMD. A reduced version of the game being shared is transferred to the PlayStation Portable without a UMD via the PlayStation Portable's Wi-Fi connection, whereupon it is loaded into RAM and runs.
