In order to illustrate technical solution described herein, it is described in detail below in conjunction with specific accompanying drawings and embodiments.
Digital video standard (DisplayPort, DP) interface is one by PC and the exploitation of alliance, chip manufacturer, video
The standardized digital video interface standard of frequency electronic standard association (VESA).The interface authentication-exempt exempts from authorization gold, is mainly used for regarding
The connection of the equipment such as frequency source and display, and also support to carry audio, the data of USB and other forms.Digital video standard
It is first display communication port for relying on packetized data transmission technology, this packetized transmission technology can be in ether
It is found in the technologies such as net, USB and PCI Express.It both can be used for internal display connection, can be used for external display
Connection.It is needed inside the differential pair of each output end unlike constant transmissions timer signal from past standard, it is digital
Formula video standard agreement is to be referred to as micro- message based on small data message, and timer signal can be embedded in by this micro- message
In data flow.Its advantage is that less number of pins, so that it may realize higher resolution ratio.Data message application also allow using
Digital video standard Extensible, this means that over time, and physical communication port itself does not need significantly to become
Change can increase additional function.Digital video standard can be used for simultaneous transmission audio and video, each single item in this two
It can individually be transmitted on the basis of no other one.Each Color Channel can have 6 to 16 in video signal path,
Audio path can have the uncompressed pcm audio of up to 24,8 channel 192kHz, or compression can be encapsulated in audio stream
Audio format.One equipment management and device control data two-way, semiduplex accessory channel carries main link, such as
VESAEDID, MCCS and DPMS standard.In addition, the communication port is can to transport two-way usb signal.
Digital video standard signal incompatible DVI or HDMI.However, dual mode digital formula video standard s is designed to use
Carry out the agreement by communication port transfers singular link DVI or HDMI1.2/1.4, needs to connect by using an external passive
Device is realized, selects required signal, and electric signal is converted to TMDS from LVDS.With by the bimodule digital of movement connector
Formula video standard s does not support VGA and double-strand to meet DVI.These communication port need active connector to convert required output
Agreement and signal.Digital video standard connector can be used to power in VGA connector, and double-strand connects DVI connector possibility
Dependent on external power supply.Digital video standard connector can have 1,2 or 4 road differential datas to (tunnel) in primary link, often
Tunnel can on the basis of self-timer runs on 162,270 or 540MHz its original code rate be 1.62,2.7 or
5.4Gbit/s.Data are 8b/10b coding, i.e., every 8 message is incorporated into 10 bit symbols.Therefore, every channel after decoding
Valid data transmission rate be 1.296,2.16,4.32Gbit/s.
Fig. 1 be the application one embodiment provide upgrade method flow diagram, the upgrade method for pair
The display for carrying digital video standard interface carries out firmware upgrade, and shown in Figure 1, the upgrade method includes:
Step S10: obtaining the expanded display recognition data of the display and the parameter of digital video standard interface, with
Determine the communication protocol of the digital video standard interface；
Step S20: the control of the accessory channel of the digital video standard interface is obtained；

Enter in display memory to be upgraded, firmware upgrade carried out to the display to realize, comprising:
S401: Xiang Suoshu display of step sends upgrade command, and receives the display and sent out according to the upgrade command
The upgrading confirmation signal sent；
Step S402: the upgrading data obtained in advance are sent to the display according to the upgrading confirmation signal；Wherein,
The display is used for after receiving the upgrading data, and the upgrading data are written in memory.
In the present embodiment, first by sending upgrade command to display, and the display is received according to the liter
The upgrading confirmation signal that grade order is sent, not only can further verify the signal of the accessory channel of digital video standard interface
Whether transmission is normal, can also be by sending upgrade command, and whether the memory detected in display be in state to be upgraded, example
Such as, by upgrade command, so that original firmware of display is in standby, to prepare the reception of upgrading data.
In one embodiment, the ascending series obtained in advance are sent to the display according to the upgrading confirmation signal
According to；Wherein, the display is used for after receiving the upgrading data, and the upgrading data are written in memory, at this
In embodiment, send upgrading confirmation signal can be host computer, the liter that host computer will be stored in host computer by that will upgrade data
In grade data storage, and the upgrading data are called after receiving upgrading confirmation signal.
In one embodiment, shown in Figure 3, it is described to be sent in advance according to the upgrading confirmation signal to the display
After the upgrading data first obtained, comprising:
S403: Xiang Suoshu display of step sends upgrading data and is sent completely instruction, and receives the display according to connecing
The upgrading data received are sent completely the upgrading data confirmation message that instruction returns；
Step S404: the upgrading data confirmation message is verified, judges whether the display completes firmware liter
Grade；
Step S405: if the upgrading data confirmation message is verified, confirm that the display completes firmware upgrade.
In the present embodiment, it is sent after upgrading data complete to display, the upgrading data are written to depositing display
In reservoir, at this point, sending upgrading data to display is sent completely instruction, display is sent completely receiving the upgrading data
Corresponding cryptographic Hash is obtained by carrying out Hash operation to the received upgrading data of institute after instruction, the cryptographic Hash is as ascending series
It is back to host computer according to confirmation message, host computer verifies upgrading data confirmation message, to determine whether display receives
To complete upgrading data, avoid upgrading data be imperfect to cause display that upgrade failure occurs in escalation process, if described
Upgrading data confirmation message is verified, then confirms that the display completes firmware upgrade.
In one embodiment, shown in Figure 4, if the upgrading data confirmation message is verified, confirm
The display is completed after firmware upgrade, further includes:
Step S406: the accessory channel of the digital video standard interface is reset to normal operating conditions.
In the present embodiment, after the firmware of confirmation display completes upgrading, by the auxiliary of digital video standard interface
Channel reset is to normal operating conditions, at this point, firmware upgrade is completed, the accessory channel of digital video standard interface carries out normal
Control information transmission.
