A universal serial bus (USB) transmission system for transmitting a monitor control signal and a data signal from a monitor system to a main frame is provided. The universal serial bus transmission system separately includes a universal serial bus interface IC and a monitor controller IC between which the monitor control signal and the data signal are transmitted through a low-speed transmission interface, thereby reducing costs for handling electromagnetic interference (EMI). Furthermore, the universal serial bus interface can be modularized to allow the monitor system to serve as a general monitor system or a USB monitor system, thereby increasing the utility of the monitor system.
A universal serial bus (USB) transmission system for transmitting a monitor control signal and a data signal from a monitor system to a main frame, the universal serial bus transmission system comprising:
The universal serial bus transmission system as recited in claimed 1, wherein the low-speed transmission interface is an I2C interface.
The universal serial bus transmission system as recited in claimed 1, wherein the low-speed transmission interface is an SPI interface.
The universal serial bus transmission system as recited in claimed 1, wherein the low-speed transmission interface is a UART interface.
The universal serial bus transmission system as recited in claimed 1, wherein the low-speed transmission interface is a RS232 interface.
The universal serial bus transmission system as recited in claimed 1, wherein the transmission rate of the low-speed transmission interface is less than 400K bits/sec.
The universal serial bus transmission system as recited in claimed 1, wherein the transmission rate of the universal serial bus interface IC is approximately 1.5M bits/sec.
The universal serial bus transmission system as recited in claimed 1, wherein the transmission rate of the universal serial bus interface IC is approximately 12M bits/sec.
A universal serial bus transmission system for transmitting a monitor control signal and a data signal from a monitor to a main frame, the universal serial bus transmission system comprising:
A method for reducing electromagnetic interference (EMI) in a universal serial bus transmission system comprising:
