Abstract
A device and a method for updating the function of a monitor according to the invention. By using the USB signal lines directly for data transmission and recording the data of a monitor controller to the erasable programmable read only memory, data update can be achieved. Moreover, the erasable programmable read only memory can be updated by separating the recording path and the normal visual path using a recording path separator of the monitor controller. Compared to the prior art, the device and the method of the invention are more convenient and time saving for function update of the monitor.
Claims27
A device installed in a monitor system for updating the function of a monitor of the monitor system, comprising:
- USB signal lines for transmitting a recording command and recorded data;
- a detecting device electrically coupled to the USB signal lines for detecting and outputting the recording command and the recorded data;
- a starting device electrically coupled to the detecting device for receiving the recording command and the recorded data and then transmitting the recording command and the recorded data when the starting device is switched from a visual path to a recording path;
- a ROM recording command decoder for converting the recording command into a erase/read/write signal and the recorded data into a address signal and a data signal by switching the starting device to the recording path;
- a ROM electrically connected to the ROM recording command decoder, of which data can be updated according to the address signal, the data signal and the erase/read/write signal;
- and
- a recovery device electrically coupled to the ROM recording command decoder and the starting device for determining whether the data stored in the ROM are already updated according the address signal, the data signal and the read/write signal and for switching the starting device from the recording path to the visual path when the data of the ROM are already updated.
A system for updating the function of a monitor, comprising:
- a recording device for storing and outputting a recording command and recorded data;
- USB signal lines electrically coupled to the recording device for transmitting the recording command and the recorded data;
- and
- a monitor controller having a monitor in system programming memory, electrically coupled to the USB signal lines, wherein if a setting command of the recorded data from the USB signal lines is correct, the monitor controller is modified according to the recording command and the recorded data, wherein the USB signal lines and the monitor controller are installed in a monitor system.
A method for updating the function of a monitor, comprising:
- receiving a plurality of signals from a plurality of USB signal lines by the monitor;
- checking if serial setting commands of the signals are correct by a monitor controller installed in the monitor, if the serial setting commands of the signals are correct, the signals from the USB signal lines are transmitted to the monitor controller by switching a transmitting path of the signals from the USB signal lines from a visual path to a recording path, and the monitor controller is modified and updated according to the signals from the USB signal lines;
- and
- determining if the monitor controller is completely achieved, if the monitor controller is completely achieved, the signals from the USB signal lines are transmitted by the transmitting path of the signals from the USB signal lines from the recording path to the visual path.
