Description

The method of work of the extension apparatus of host computer

Technical field

The present invention relates to a kind of method of work of extension apparatus of host computer, exactly, relate to and a kind ofly be connected to the method for work of the extension apparatus of host computer, belong to field of computer technology by industry ethernet interface or usb bus interface or Wireless USB antenna.

Background technology

Since computing machine is released so far, the overall performance of computer CPU is constantly promoting, and now, the computer CPU dominant frequency has reached more than the 3Ghz, and two cpu chips and multi thread CPU chip all emerge, and the function of computing machine becomes from strength to strength; The develop rapidly of microelectric technique makes that the communication speed between computing machine and its peripherals also is greatly improved simultaneously.The Ethernet interface of hi-speed USB interface that links to each other with computing machine and 1 kilomegabit (1Gigabit/s) for example can make computing machine and its peripherals swap data or obtain information needed or data resource from the Internet by Ethernet interface soon and share soon.

Existing host computer and display and other input-output device (as mouse etc.) all must be put together, when the user need use computer in different places, must move existing computer to new local or buy a new computer in addition.A kind of character formula computer terminal is arranged now, and it can be opened in different places with the host computer branch, and a host computer can connect several character formula computer terminals simultaneously, to save hardware cost.This computer terminal has been widely used in some specific area at present, as banking system.But, connected mode between this computer terminal and its main frame and technology have determined can't the transmitted image signal, cause the user interface of its demonstration unfriendly, the user uses inconvenience, also causes it can't enter family market and teaching market widely simultaneously.Because the user interface close friend and the easy operating of WINDOWS operating system, accepted extensively and use by people, comprise and extensively enter family user market, make modern people's work, study, life and even amusement all rely on computing machine more and more, even people's life style is also ceaselessly changing because of the development of computing machine.

Because the difference of demand, often having two or more kinsfolks need use a computer simultaneously.Therefore, the family that has an above computing machine now is more and more, and simultaneously a lot of new household electronic products also rely on computing machine more and more, for example has some manufacturers produce to go out family expenses multimedia hub device based on host computer.Because various restrictive conditions, for example computing machine and TV be not or not same place, perhaps two or more users need use a computer simultaneously, make the user must buy the computing machine more than two even two, cause the overlapping investment of user's hardware cost and software cost, also will take big quantity space; In addition, existing host computer and display and peripherals such as keyboard, mouse all must be installed together nearby, in the abominable place of some environment (as workshop), just computing machine can not be installed.In a word, present terminal is because the technical deficiency of himself can not solve above new demand.

Ethernet (ETHERNET claims LAN (Local Area Network) again) interface has been widely used in the computer industry as a kind of high speed universal serial bus standard interface.People are connected to the Internet by the Ethernet interface of computer, seek required information.Release based on the network interface card of per second 1 kilomegabit (1Gigabit/s) Ethernet interface fast, 10,000 megabit Ethernet interface standards are also in development.USB interface is widely used in the computer industry equally as another kind of universal serial bus standard interface.At present, studying and formulating (abbreviation: the UWB) Wireless USB of technology (Wireless USB with several large enterprises headed by the INTEL Corp. based on ultra broadband Ultrea-Wideband, be called for short: standard agreement WUSB), Related product are about to release at the beginning of the end of the year 2005 or 2006.In 3 to 4 meters scope, the transfer rate of WUSB will reach the transfer rate of prior USB 2.0, the release of the WUSB of 480Mbps will provide better products ﹠ services for family, enterprise with existing cable LAN WIRED LAN, WLAN (wireless local area network) Wireless LAN and wired USB.

Now, all computers all are furnished with Ethernet interface and USB interface.Release along with high speed USB standard, wireless WUSB standard and fastethernet interface standard, how to develop a kind of cheapness, plug and play and based on the extension apparatus and the method for work thereof of the host computer of Ethernet interface or wireless WUSB interface or USB interface, so that this extension apparatus can be away from host computer; Simultaneously, also allow wireless WUSB type input-output device or USB type input-output device or display be installed on the extension apparatus away from host computer, both can on host computer, control the peripherals that is installed in extension apparatus, also can control on the peripherals of extension apparatus and shared host computer on peripherals and data, and can satisfy various new demands, just become the new problem that people pay close attention to and research and develop.This device is supported plug and play, and is easy for installation, need not insert hardware in the host computer interface slot.For example, when this extension apparatus is connected to host computer by Ethernet cable, can be installed in and reach 100 meters place away from host computer, simultaneously can also make the image information of same host computer be sent to the extension apparatus of a plurality of host computers simultaneously by router ROUTER or Ethernet converter ETHERNET SWITCH, and, when if this extension apparatus is equipped with wireless WUSB master controller, this extension apparatus can link to each other with wireless WUSB equipment by wireless WUSB antenna simultaneously, need not be by traditional USB cable, therefore this device can be widely used in various occasions, has great social value.

Summary of the invention
