Detailed description of the invention
Here will illustrate exemplary embodiment in detail, its example represents in the accompanying drawings.When explained below relates to accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawings represents same or analogous key element.Embodiment described in following exemplary embodiment does not represent all embodiments consistent with the present invention.On the contrary, they only with describe in detail in appended claims, the present invention some in terms of the example of consistent apparatus and method.
First the embodiment of the HDMI method of automatic configuration that the application provides is illustrated.Fig. 2 is the HDMI method of automatic configuration flow chart that one embodiment of the application provides, and Fig. 3 is data transmission schematic diagram between the display device hardware configuration of application the method and hardware；With reference to Fig. 2 and Fig. 3, the method comprises the steps.
Whether S11, detection HDMI receive the source data from external video source device；
S12, when HDMI receives the source data from external video source device, from described source data, obtain the type identification information of target video.
Hardware structure diagram as shown in Figure 3, method described in the present embodiment can have been performed automatically by SOC 202.Wherein, the above-mentioned type identification information derives from the source data (such as video data, control signal etc.) that external video source device 100 exports to HDMI 201, and SOC 202 can obtain the type identification information by communicating with HDMI 201.
S13, determine the target version matched with described target video according to described type identification information.
The above-mentioned type identification information characterize external video source device 100 output target video belong to which kind of type (as, it is 4K/30Hz, or 4K/50Hz etc.), such that it is able to according to the matching relationship between video type and HDMI version, determine the target version matched with target video.
S14, according to described target version, HDMI is carried out version configuration.
As it is shown on figure 3, after determining target version, SOC 202 can generate corresponding version switching signal, and by this version switching signal, the transmission of this version switching signal is realized the configuration (version switching) to HDMI 201 to HDMI 201.
From above technical scheme, the embodiment of the present application is by obtaining the type identification information of target video in the source data that receives from HDMI, and the target version matched with target video is determined according to the type identification information, then according to this target version, HDMI is carried out version configuration, so that the real work version of HDMI matches with target video.Visible, the version configuration process of above-mentioned HDMI need not user intervention, can automatically be performed by the system level chip of display device completely, thus in the case of user does not possesses relevant professional knowledge, it is also ensured that HDMI version is correct and switches in time, do not have video and the miscue such as cannot play, improve Consumer's Experience likability.
In one feasible embodiment of the application, the type identification information of the target video described in step S12, specifically may include that
State and the currency controlling data channel (Status&ControlDataChannel, SCDC) is extracted from the source data that HDMI receives.
Accordingly, described in step S13, determine, according to described type identification information, the target version matched with described target video, specifically may include that
If the currency of the described SCDC extracted is the first preset value, it is determined that described target version is 1.4 versions；
If the currency of the described SCDC extracted is the second preset value, it is determined that described target version is 2.0 versions.
Optionally, the value of SCDC data can be logical type, and the most above-mentioned first preset value is specifically as follows logical zero, and accordingly, the second preset value can be logic 1.Owing to external video source device 100 also possesses video type arbitration functions, therefore when high-quality videos such as its output 4K/50Hz or 4K/60Hz, it is simultaneously by the value set of SCDC, i.e. it is set to " 1 ", and export to HDMI with control signal form, and when the video of its output 4K/30Hz or more low resolution/frame per second, the value of SCDC is set to " 0 " by it simultaneously, and export to HDMI with control signal form.In the present embodiment, SOC i.e. utilizes the above-mentioned characteristic of external video source device, determines the type of target video, and then determines target version.
With reference to Fig. 4, in one feasible embodiment of the application, described in step S14, according to described target version, HDMI is carried out version configuration, specifically may include that
S141, judge that the current version of HDMI is the most consistent with described target version；
If the described current version of S142 is inconsistent with target version, then generate version switching signal；
S143, by described version switching signal, HDMI is carried out version configuration.
I.e. when the current version that the SOC of display device judges HDMI is inconsistent with target version, generate and send version switching signal to HDMI, by this version switching signal, HDMI being reconfigured so that it is version switches to target version.
Certainly, if the current version of HDMI with determined by target version consistent, then need not switch the version of HDMI, SOC is not required to want HDMI and sends version switching signal, thus display device can directly performance objective video transmission, decode and broadcasting etc. operates.
In one feasible embodiment of the application, described in above-mentioned steps S143, by described version switching signal, HDMI is carried out version configuration, specifically may include that
Obtain extending display identification data EDID corresponding with described target version in HDMI；
