Display unit with monitor, USB hub, and device bay integrated controller

The present invention relates to a display device having a monitor, a USB hub, and a device bay integrated controller. More specifically, the present invention relates to a monitor, a USB hub, and a monitor that allow a single controller to control a monitor as well as a USB hub and a device bay. A display device having a device bay integrated controller is provided.

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 have emerged, peripheral devices controlled by a computer have rapidly increased.

As a result, the current 1: 1 connection between computers and peripheral devices has reached saturation in terms of scalability of peripheral devices. I decided to find ways to connect peripheral devices.

As a result, Universal Serial Bus (hereinafter abbreviated to USB) for medium and low speed data transmission and IEEE 1394 for high speed data transmission have emerged as a standard as a new communication protocol centering on a computer.

As the number of peripheral devices attached to the PC increases in recent years as the number of applications increases, USB and IEEE 1394 exceed the limits that the PC slot can accommodate. New communication protocol with the concept of hot plugging or hot plug-and-play, which is supported by PCs, telephone companies and display device manufacturers to provide the convenience of PC operation. to be.

Here, USB is applied to medium and low speed devices of 12Mbps or less, such as various modems, printers, joysticks, mice, keyboards, scanners, etc., and IEEE 1394 is used to transmit data such as digital cameras, video cassette tape recorders, optical disc players, and the like. Applied to high speed devices with speeds of 100 to 400 Mbps.

In addition, the Device Bay System allows users to add or upgrade devices, such as peripherals on the computer body, to mount the device as if a video tape was inserted or removed without opening the chassis of the computer body. Or a device corresponding to a device such as a peripheral device of a computer body of a concept such as a video cassette tape recorder (VCR) corresponding to a video tape configured to be detachable, and a form of the device bay may be mounted to the computer body. It can also exist separately, sometimes referred to as a device bay.

The device bay for implementing such a function is a communication means between a computer main body and a device mounted in the bay, and transmits data, control signals, and power using IEEE 1394 or USB.

Therefore, in the future, any peripheral device will be able to be easily connected to a multimedia environment peripheral to the computer body without any prior knowledge by USB, IEEE 1394 and the device bay.

In order to control such a device bay, device bay control means including an IEEE 1394 and a USB interface block are required.

Interface to enable data transfer.

The USB hub 50 transmits a device mounting or detachment recognition signal input from the device bay controller 20 to the computer main body, and transmits a control signal for controlling the operation of a device input from the computer main body to the device bay controller 20. When the device mounted in the bay unit 10 is in an operable state, the controller transmits and transmits control signals and data between the medium and low speed devices mounted in the bay unit 10 and the computer main body.
