Description

Display device with 1394 CD-ROM and application control keys

The present invention relates to a display device of a computer system.

More specifically, it includes a 1394 CD-ROM (hereinafter referred to as 'CD-ROM') and a self-powered 1394 repeater board and a USB hub board provided for high speed serial communication. It is also supplied to the 1394 CD-ROM, and includes a key button section for inputting a command to execute a 1394 CD-ROM or other Windows application so that the 1394 CD-ROM is directly mounted to the display device, and also a predetermined portion of the display device. The 1394 CD-ROM and other Windows applications can be run through the USB hub board by operating the function buttons provided at the same time. The convenience of using the 1394 CD-ROM and Windows applications can be improved. A display device having a 1394 CD-ROM and an application program control key.

Recently, as a new type of computer environment such as a multimedia computer and a home network, and a communication environment centered on a computer, a protocol for high speed serial communication has emerged, IEEE1394 and USB (Universal serial bus). .

These USB and IEEE1394 are a new communication protocol of the concept of hot plugging or hot plug-and-play. USB is a data transmission method such as modem, printer, joystick, mouse, keyboard, scanner, etc. It is applied to medium and low speed devices of 12 [Mbps] or less, and IEEE1394 is applied to high speed devices such as digital cameras, video cassette tape recorders, optical disc players, etc., whose data transfer rate is about 100-400 [Mbps].

In addition, for serial communication by USB or IEEE1394, a dedicated chip or a board containing a dedicated chip, which functions as an interface function such as classifying power in addition to transmitting and receiving data due to direct electric signal flow, requires a USB hub. A board containing a chip (hereinafter referred to as a "USB hub board") and an IEEE1394 board called a "physical layer" (hereinafter referred to as a 1394 physical layer) chip (hereinafter referred to as a 1394 repeater board) Will perform this function.

Meanwhile, the power supply method for operating the USB hub board and the 1394 repeater board includes a signal and power transmission cable (hereinafter referred to as a 'USB cable' and a '1394 cable') according to each standard. In other words, there is a bus power method for supplying driving power and a self-power method using an independent power supply device.

A CD-ROM is widely used as a recording device that optically reads out multimedia data such as recorded video and audio and delivers the same to a user by using a predetermined output means, and is generally provided in a computer main body.

However, there was a difficulty in using the installation program provided by the manufacturer in order to properly install the installation, and in some cases, have a small amount of computer knowledge such as adjusting jumpers.

To solve this problem, we developed a hot-plugging CD-ROM that can be installed on a computer and installed in hardware or software, and can be used immediately by a user. There is a 1394 CD-ROM to carry.

However, since the 1394 CD-ROM as described above was also built into the computer main body, when the user installs the computer system in a narrow space, the computer main body should be placed in a separate location from the display device. In this case, the 1394 CD-ROM There is a disadvantage in that it is inconvenient to operate a function key button provided in a 1394 CD-ROM main body such as mounting or detaching or playing or stopping.

On the other hand, the 1394 CD-ROM can be operated by the application program of the computer, but in this case, it is cumbersome to execute the necessary application program first, which is the case of sending an e-mail using the Internet. The same problem occurred when trying to execute other applications.

Therefore, an object of the present invention is to mount the 1394 CD-ROM directly to the display device of the computer system and to use the power supplied to the 1394 repeater board by the self-power method, and the 1394 CD-ROM to a predetermined portion of the display device 1394 CD-ROMs and application programs that can enhance the convenience of using 1394 CD-ROMs and Windows applications by providing one or more function keys for one-touch input of commands to execute Windows applications. A display device having a control key is provided.
