PURPOSE: A multimedia USB(Universal Serial Bus) memory stick equipped with an MPEG4(Moving Picture Experts Group) contents playback function, an MP3(MPEG level 3) function, and a digital camcorder function is provided to offer portability and convenience to a user by installing multimedia functions in a small space with an SOC(System-On-Chip). CONSTITUTION: A device comprises the USB memory stick, an SOC block, a TFT(Thin Film Transistor) LCD, a digital camcorder, an MPEG4 player, and a battery. The SOC block is equipped with a CPU, a graphic accelerator, a buffer memory, and a driver to connect with an LCD and a camera. The MPEG4 player uses an MPEG4 Codec(Coder/Decoder) and an AAC(Advanced Audio Codec) to compress or decompress moving image/audio data. When the device is connected to a computer, the device is operated by using the USB power and charges the battery. An OS(Operating System) and an application program operating components are stored in the USB stick memory.
