If you use the terminal alone, you should use a handheld OS such as Pam3 or Windows CE. If you connect to the docking system, you can use a desktop-only OS such as Windows 98 or 2000.

Therefore, the partitions of the hard disk 102 are held in two C and D in advance, and the CMOS SETUP program of the microcomputer 10 is operated as follows.

First, when the power switch is turned on by the terminal alone without connecting the terminal to the docking system, power is supplied to the terminal 4 (S31).

Then, the microcomputer 101 loads and executes the CMOS program of the ROM 107 (S32), and is controlled by the CMOS program to determine whether the docking system 200 is connected (S33).

If the docking system 200 is not connected, the microcomputer 101 includes a hard disk 102, a RAM 103, a sound card 106, and an MPEG card 105. Only the TFT display unit which is connected to the COM1 104 and the terminal is set up and operable (S34).

Next, the microcomputer boots into an OS for Pam3 or a handheld-only OS such as Windows CE installed in the C driver of the hard disk 102 (S35).

In this state, the user performs various tasks using the terminal.

That is, when the user holds the terminal in hand and uses the GPS function to go hiking, fishing or various trips, he can know his location on the map wherever he is, without losing his way, when driving in the big city or at low distances or You can easily find your destination when you are driving at night, and you can watch AM FM Radio and TV, the most basic media, anytime, anywhere.

In addition, the digital camera function can take moving pictures and still pictures, the digital recorder function can record various meetings, lectures or important conversations, the wireless telephone function can be used anytime, anywhere, and wired and wireless video call function You can make a face-to-face call with the other party, send and receive emails via the wireless Internet function, and access anything on the Internet like a regular computer at home by accessing a large portal site. MP3 Player function allows you to listen to music, read music from music CDs, etc. to create MP3 files, access to the station's homepage using the wireless Internet, view drama-like videos, and download video data to the hard disk. You can also watch the video player again at any time. You can make music from TV or Radio into MP3 files, record TV scenes as moving pictures, take cool shots of TV scenes one by one, save them, and write cartoon novels like e-books. Download and save to the Internet to see when you want to see at any time, you can also download and save a variety of computer games to play when you want to play, using the solar generator attached to the back of the terminal while continuing to charge the battery 1 You can use the terminal for a long time with two batteries.

On the other hand, when the user connects the terminal to the docking system and turns on the power switch, the microcomputer 101 senses that the docking system is connected under the control of the CMOS program of the ROM 107.

Next, the microcomputer 101 includes a hard disk 102, a RAM 103, a sound card 106, an MPEG card 105, a COM1 104 CD-ROM driver unit 22, and a TV signal conversion unit 23. ), The graphics card unit 24, the input / output unit 26, and the hard disk 29 are SETUP to enable operation (S36),

Then, the microcomputer 10 operates by booting with a desktop OS program such as Windows 98 or 2000 installed in the D driver of the hard disk 102 (S37).

Then, the microcomputer reads and loads various business and entertainment programs onto the CD-ROM, and the user performs various tasks with a dedicated monitor. You can also see it on the screen.

In addition, you can watch movies on DVD, charge the battery of the terminal, use a computer monitor with a high-resolution graphic card, connect all multimedia devices with various input / output devices, and use them together. Using amplifiers and speakers, you can play movies or video games with loud, high-quality 3D sound in the office or in the car.

In addition, you can use the program from various word processing programs for writing documents to various business programs by inputting programs on various CDs like a general computer, and ZIP driver or 3.5 inch FDD or CD-RW or tape backup using USB terminal or printer port. A driver can be used, and in an office or home, a high-speed modem can be connected by a wired cable such as an optical cable or an SDSL line to use the Internet for a long time at a lower cost than the wireless Internet.

In addition, the power supply unit can be used as a 100V 200V or 12V car cigar tweeter, so it is possible to use a TV, a movie, a cartoon entertainment game, etc. in a car, a condo or a hotel while traveling, and use an AM FM Radio and a TV receiver in an outdoor place such as a fishing ground. With this handheld multimedia terminal and docking system, you can expect to use a lot of different multimedia.

In addition, all other terminals listed up to now are all self-contained, so the main computer must be separately located in the home or office. Therefore, various programs can be used only by periodically connecting the terminal to the computer to exchange data. The handheld multimedia terminal and the docking system of the invention do not need a main computer separately because they are themselves excellent multimedia computers.

And if you make various connections and use it, it can be a universal multimedia with another function.

In addition, users are very economical because they do not need another computer, and the computer speed (CPU) continues to be newly released. A user who uses the multimedia terminal and the docking system of the present invention uses the computer every year. You don't need to buy it again, just buy the microcomputer 101 card, and the upgrade can be easily solved at a low cost. If you upgrade your phone by replacing parts of the phone, modem, camera, etc. with new parts every time, you will always have the latest comprehensive multimedia equipment for a long time. It can be used more economically.

In the above-described embodiment, the partitions of the hard disk 102 are set to two Cs and Ds, and two OSes are used by using the CMOS program of the microcomputer 10, but these may be variously modified. When using only the terminal is booted to the hard disk 102 to use the OS such as Pam3 or Windows CE, when using the terminal connected to the docking system booted to the hard disk (29) Windows 98, 2000 or Windows NT You can also boot the same desktop OS.

And if you need to, you can even boot into three operating systems, or even more, to use Linux programs.

As described above, in the embodiment of the present invention, a handheld multimedia terminal and a docking system that implements a variety of multimedia while moving only one multimedia terminal, and can implement more functions than a normal computer by connecting the terminal to the docking system Can provide.

And another computer is not needed at all, providing a very economical terminal system.
