Description

Display firmware update method and application system thereof

The present invention relates to a firmware updating method and an application system thereof, and in particular, to a firmware updating method for a display and an application system thereof.

Firmware is software embedded in a hardware device, such as a program that is executed by a computer. At present, firmware has been widely used in various electronic products, such as remote controls, computers, keyboards in computers, monitors, hard disks, industrial robots, etc. With the rapid development of media technology, firmware updates can ensure that the hardware of electronic products is kept up-to-date and compatible, thereby improving hardware performance and reliability.

Updates to new firmware are usually released by hardware manufacturers or software designers to fix bugs, improve performance, add functions, or improve security vulnerabilities of older firmware. A typical firmware update operation must first download and obtain a new version of the firmware update file through the network or storage medium (such as an external computer, flash drive, memory card, or others), and then erase, rewrite or replace the storage medium through current. way to update the old firmware file in the hardware device.

Taking the firmware update operation of the monitor as an example, there are mainly three types of firmware update operations currently used. The on-screen display (OSD) starts the firmware file and program update process. The second method is that the user connects an external computer with a U Universal Serial Bus (USB) cable to download a new version of the firmware update file, and then uses the commands from the external computer to update the firmware file and program. The third method is to connect to the server through the network, using a programmable network module to connect to the set file transfer protocol (File Transfer Protocol, FTP) server to download the new version of the firmware update file, and then Firmware files and program updates are performed by the monitor's image scaling controller (scaler).

However, due to the first and second firmware update methods, the access to the firmware file must be performed by manually operating an external data storage device (eg, a USB flash drive or a computer memory), which is less convenient. And there may be errors in the file update due to unexpected human factors. In addition, the external data storage device cannot update the data in time, and the data expansion is also insufficient. In the third method, additional network equipment, such as routers, firewalls, etc., needs to be added to construct a specific programmable network module and a file transfer protocol server, which increases the manufacturing cost of the display.

Therefore, there is a need to provide an advanced display firmware update method and an application system thereof to solve the problems faced by the prior art.

An embodiment of the present specification provides a display firmware update method, which includes the following steps: first, input an address of a remote universal serial bus device in a screen setting menu of the display. Afterwards, the USB/IP communication protocol is used to enable the built-in near-end universal serial bus device of the display to share the firmware update data in the remote universal serial bus device through the local area network according to this address. Then use this firmware update data to update the firmware settings in the monitor.

Another embodiment of the present specification provides a display firmware update system built in a display, including: an image scaling controller, a screen setting menu, a USB Hub, and an Ethernet/Universal Serial bus (Ethernet over USB) module. The on-screen setup menu is used to enter the address of the remote universal serial bus device. The display firmware update system adopts the USB/IP communication protocol, so that the built-in near-end universal serial bus device of the display can share the remote universal serial bus according to this address through the Ethernet/Universal Serial Bus module. Firmware update data in the device, and use this firmware update data to update the settings in the display.

According to the above-mentioned embodiment, this specification provides a display firmware update method and an application system thereof. The USB/IP communication protocol is used to enable the built-in near-end universal serial bus device of the display to connect to the display through the Ethernet/Universal Serial Bus. The bus module shares the firmware update data in the remote universal serial bus device according to this address, and uses the firmware update data to update the settings in the display.

The user only needs to use the existing local area network, specify the address of the remote universal serial bus device in the screen setting menu of the display, and access the storage in the USB/IP communication protocol and the universal serial bus device access technology. The remote universal serial bus device is installed, and the firmware update function is turned on, and the new firmware update file can be downloaded from the remote universal serial bus device to complete the firmware update operation of the display. There is no need to manually download update programs and firmware files, and there is no need to add external network equipment. It can take into account the convenience of operation, reduce unexpected human operation errors, and reduce equipment costs.
