A portable multimedia player (PMP) is a consumer electronics device that is capable of storing and playing digital media. In PMPs, the data is typically stored on a hard drive, microdrive or flash memory. PMPs are capable of storing  images, and even playing digital audio and video. Usually, a colour LCD or OLED screen is used as a display. Various players include the ability to record video, usually with the aid of optional accessories or cables, and audio, with an inbuilt microphone or from a line-out cable or FM tuner. Some players include readers for memory cards, which are advertised to equip players with extra storage or transferring media. Image files are usually viewed on the JPEG format and some players, like the iPod series provide compatibility to additional file formats like GIF, PNG and TIFF.More and more devices are now equipped with a touch screen as the primary or alternate input. This can be for convenience and/or aesthetic purposes.
