The present invention relates to a video learner, and more particularly, to a learning multimedia player using a ubiquitous network that can play a learning video by place, subject, and level through a server and an individual storage device using a ubiquitous network.

In general, a portable multimedia player (PMP) is a format for downloading and playing a required file by connecting to a computer. The portable multimedia player (PMP) can play a video and watch a video desired by a user.

In addition, the multimedia player was able to receive and watch data in real time in a streaming format through the Internet, a mobile communication network, and the like.

However, since the video player does not support wired or wireless LAN, there is a problem that it is not possible to select and play contents by using the Internet network. Also, the WM9 file (Window media player 9) for playing an educational broadcasting program suitable for learning can be used. There is a problem that it is difficult to play the WM9 file because it does not support the video to play.

In order to solve the above problems, the present invention provides a ubiquitous network that can be conveniently played by first supporting the learning video WM9 file (Window media player 9) for each place, subject, and level through a server and individual storage devices using the ubiquitous network. The purpose of the present invention is to provide a learning multimedia player.

The present invention is a player made to play a video by downloading or streaming a video file,

The controller unit includes a system-on-a-chip (SOC) 110, a flash memory unit 120, and a dynamic random access memory (DRAM) 130, which is a volatile memory, for reproducing the image. 100) and the CVBS (Composite Video Blanking Sync) signal in which the video signals (color, luminance, and sync) are mixed in one signal and the audio 220 signal is not included in order to output the file stored in the controller unit 100. The image and sound processing unit 200 and the controller unit including a TV interface 210 for processing a video signal and an audio display unit 230 including an audio 220 for processing an audio signal together with the video signal. By connecting the video signal to the wire 100 and wired, the network unit 300 and the main controller 100, which are configured to stream video through a server and a network, can be selected and outputted and controlled. The interface unit 400 including the remote controller signal input / output unit 410 and the keypad menu interface 420 and the USB memory unit 500 and the main controller 100 configured to store the image signal through a USB memory which is a portable memory. It is composed of an adapter power supply unit 600 to supply power through the adapter, or to enable the image input and output through the battery.

The system-on-a-chip (SOC) 110 of the main controller 100 is a reduced instruction set computer (RISC) 200MHz or more, MPEG4 (140) function to support the image output Is done.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
