Abstract

A portable audio video electronic recording, storage and playback device. A user can store their music or movies and view them on the built-in color display or on a television. Video can be recorded and stored from any video source. Digital photographs or video can be captured via a built-in camera. A built-in TV tuner provides viewing and recording of television programming. Music can also be recorded from a stereo or computer and played back anytime and anywhere. The audio can be listened to with headphones, with the built-in speaker, or by connecting the device to a stereo. An image viewer allows digital photos to be stored and viewed on the device. Images can be easily transferred between the device, digital cameras and computers. A hard disc drive and memory card port are provided for storing data. An infrared port provides remote control and wireless connectivity.
