The information of format is expanded, that is, carrying out the expansion of EDID information.
In this embodiment it is possible to by the information of collected exemplary video format, according to the information of exemplary video format
In the size of pixel clock (pixel clock) be ranked up, for example, when according to pixel in the information of exemplary video format
The sequence of clock (pixel clock) from small to large is ranked up
In the information of exemplary video format after sequence, the information of adjacent company exemplary video format is therefrom selected,
For example, the two neighboring exemplary video format of selection is respectively A and B, the resolution ratio of corresponding pixel clock be respectively Pa and
Pb, and Pb > Pa.Optionally, the selected expansion step-length of the embodiment can be len, the two adjacent exemplary video formats
Between the resolution ratio number of expansion video format that can expand out can be carried out according to (Pb-Pa)/len after rounding it is true
It is fixed.
Fig. 3 is the process for expanding the method for resolution ratio out between a kind of two video formats according to an embodiment of the present invention
Figure.As shown in figure 3, method includes the following steps:
I=0 is arranged in step S301；
Step S302, judges whether i is less than n.
If it is judged that i is less than n, step S312 is executed；If it is judged that i is not less than n, then terminate to execute process.
Step S303 determines the information for expanding video format i.
In this embodiment, pixel clock=Pa+i*len, as i=0, pixel clock=Pa, that is, being A
The resolution ratio of the pixel clock of exemplary video format.As i=1 to n-1, pixel clock is for indicating n-1 expansion video
The resolution ratio of the pixel clock of format, and each other information in addition to the resolution ratio of pixel clock for expanding video format,
It can be identical as the information of exemplary video format A.
Step S304, i++.
In this embodiment, after the information for getting an expansion video format, i++ executes step S302,
That is, starting to execute the next process for expanding video format of creation, until i is more than or equal to n.
In this embodiment, new EDID file is created according to each video format come out that expands, by the expansion video
The information of format is stored in first detailed temporal specification module of EDID file, and the information of other video formats, than
Such as, fixed time sequence and standard time sequence mark etc., do not select to support.Optionally, if chip to be measured is applied to simulative display
Field then can set 1 for byte [14H] bit7 of EDID；If the chip to side is applied to digital display field, can
To set 0 for EDIDByte [14H] bit7, EDID file is finally saved as.Optionally, the name packet of the file of the embodiment
The main information of video format is included, for example, including pixel clock, Hactive, Htotal, Vactive, Vtotal etc., this
Place is with no restrictions.
It in this embodiment, can be according to for the determination of the EDID file of every two adjacent exemplary video formats
Above-mentioned steps S301 is determined to the method for step S302, is no longer repeated one by one herein.
In this embodiment, the information of multiple exemplary video formats is acquired, and according to the information of multiple exemplary video formats
Multiple EDI files are created, the information of collected multiple exemplary video formats is expanded, multiple expansion video formats are obtained
Information, and according to it is multiple expand video formats the multiple EDI files of information creating, ultimately form the set of an EDID.
In this embodiment, EDID set is established, the video format for including in EDID set is abundant, not only comprising typical case
Video format, can also include the expansion video format generated according to exemplary video format, so as to preferably determine
Support characteristic of the chip to the different video format traversed under different video cards.In each EDID, a kind of video is only supported
Format, a kind of video format can be placed in first detailed temporal specification module of EDID, and using therein
When EDID, the video format that video card is sent out is determining, different in this way video card when using each EDID therein, by
A kind of video format is only supported in each EDID, is only issued a video format, can be tested different video cards in the EDID institute
Expressive ability under the video format of support improves the efficiency tested chip.
