Playstation portable (psp)

The PlayStation Portable (PSP) is a handheld game console released and manufactured by Sony Computer Entertainment. The PlayStation Portable has the ability to play video games, watch videos, listen to music, view images, as well as Internet browsing functionality (!!!).
PlayStation Portable's audio player supports a number of audio codecs, including AAC, MP3, and WMA, and has the option to be played with or without a set of five visualizations. The image viewer will display several common image formats including JPEG and PNG.
MPEG-4 and AVC video formats are also compatible with PlayStation Portable. With reasonable video and audio bit-rate settings (a resolution of 320×240, a video bit rate of 500 Kb per second, and an audio sampling rate of 22050 kHz) a 22 minute video file is roughly 55 MB, enough to fit on a Memory Stick Duo as small as a 64 MB. At the same rate, a hundred-minute feature film can fit on a 256 MB Memory Stick. Many movie files, both free-to-distribute and copyrighted, have been encoded for the PlayStation Portable and are available on the Internet. Game and movie trailers are increasingly available, even from the studio's official site.
There are numerous software applications and hardware devices specifically designed for PlayStation Portable's various media-centric applications.
Battery life
PlayStation Portable's default battery life varies widely depending on application from less than 3 hours while accessing a wireless network and having screen brightness on its highest setting to more than 10 hours during MP3 playback with the screen turned off. An extended-life 2200 mAh battery will increase this by approximately 20%. A sleep mode is also available that uses minimal battery power to keep the system's RAM active, allowing for "instant on" functionality when you disable sleep mode.
