Problems solved by technology

Due to various constraints, such as the computer and the TV are not in the same place, or two or more users need to use the computer at the same time, the user must purchase two or more computers, resulting in the user's hardware cost and software cost. Repeated investment will also take up a lot of space; in addition, the existing computer host and peripherals such as monitors, keyboards, and mice must be installed together nearby. In some places with harsh environments (such as production workshops), computers cannot be installed.
In short, the current computer terminal, due to its own technical insufficiency, cannot solve the above new needs

Abstract

The related extended device for a host computer comprises a control circuit with a dc power, a WUSB / USB controller (or Ethernet physical layer transceiver) with corresponding interface, a USB bus bridge (or Ethernet bridge), a MPU, and the connected peripheral devices (the image display card or image display chip, a WUSB / USB main controller, a data memory, and a non-volatile Flash memory). This invention is benefit to operate even far away the computer and can connect to display or TV with different interfaces and devices, and makes every extended device select different devices and share the program and data in the host computer.

Description

Technical field [0001] The present invention relates to an extension device and method of a computer host, specifically, to an extension device connected to a computer host via an Ethernet bus interface or a USB bus interface or a wireless USB antenna and a working method thereof, belonging to the field of computer technology. Background technique [0002] Since the introduction of computers, the overall performance of computer CPUs has been continuously improved. Now, the main frequency of computer CPUs has reached more than 3Ghz, dual CPU chips and multi-threaded CPU chips have been available, and computer functions have become more and more powerful; at the same time, micro The rapid development of electronic technology has greatly improved the communication speed between computers and their peripheral devices. For example, a high-speed USB interface connected to a computer and a 1 Gigabit / a Ethernet interface can enable the computer and its peripheral devices to exchange data...
