Abstract

The invention discloses a system for updating a firmware. The system utilizes display port interfaces to update the firmware, and comprises source equipment and terminal equipment which are provided with the display port interfaces. The source equipment comprises a storage circuit and a secondary channel of the source equipment, wherein the storage circuit is used for storing and providing an updated firmware; and the secondary channel of the source equipment is used for outputting the updated firmware with a secondary channel signal format according to the updated firmware. The terminal equipment comprises a secondary channel of the terminal equipment, an I<2>C secondary channel equipment server of the terminal equipment, and a storage unit, wherein the secondary channel of the terminal equipment is used for receiving the updated firmware with the secondary channel signal format, and producing an output signal according to the updated firmware; the I<2>C secondary channel equipment server of the terminal equipment is coupled with the secondary channel of the terminal equipment, receives the output signal, and produces the I<2>C concerted updated firmware; and the storage unit is used for updating the firmware according to the I<2>C concerted updated firmware. In addition, the invention also discloses a method for updating the firmware.

Description

technical field [0001] The present invention relates to a firmware update method and system, in particular to a firmware update method and system for updating display firmware. Background technique [0002] Generally speaking, the firmware stored in the display control device inside the display is used to determine various display parameters and then control the operation of the display. Since the firmware needs to be updated with different user needs or to improve the operation of the display, therefore The known technology transmits the updated firmware via the display data channel (Display Data Channel) of the traditional display receiving interface (such as Digital Visual Interface (Digital Visual Interface), High Definition Multimedia Interface (High Definition Multimedia Interface), etc.) through the transmission port of the personal computer to The display control device is used to update the firmware, wherein the display data channel is independent from the audio-vid...
