Example 1

Referring to fig. 1, the present embodiment provides an EDID adaptive method, which is applied to a display device such as a television, and the method can implement the version adaptation of an EDID file, does not require a user to perform manual switching, and can effectively avoid that the user sees an abnormal image when decoding a video, thereby greatly improving user experience, and the like. This method is described in detail below, as shown in fig. 1.

Step S110, when receiving a video signal input by an external device, a display device displays a preset graph, and performs video image decoding on the video signal according to a prestored EDID file with the highest version.

EDID is a VESA (Video Electronics Standards Association) standard data format, which contains performance parameters of the display device, and may specifically include device vendor information, supported maximum image size, image color setting, limitation of image frequency range, and information such as name and serial number character string of the display device. The display device can identify different HDMI signals through EDID files of different versions, and normal playing is achieved.

Exemplarily, when the display device detects that an external device inputs a video signal through the HDMI port, the display device decodes the video image according to the EDID file of the highest version and determines whether the current version can be decoded successfully. Meanwhile, in the process of decoding and judging by the display equipment, the display equipment also displays a preset graph to prevent a user from seeing decoded abnormal images, such as a screen splash, a green image and the like, and the watching experience of the user can be improved.

Generally, different versions of EDID files, such as 1.4 version EDID file, 2.0 version EDID file, etc., are stored in advance in the display device, and the version files include the highest version EDID file. Among them, the EDID file of version 1.4 can support the HDMI1.4 signal, and the EDID file of version 2.0 can support the HDMI2.0 signal. Thus, when video signals with different formats are accessed, the display device can be switched to different version files for supporting video playing. For example, when the display device outputs EDID file information of version 1.4 to the external device, the external device considers that the display device can support the HDMI1.4 signal, and accordingly, video playing is performed at the picture resolution corresponding to the HDMI1.4 signal.

In this embodiment, the EDID file of the highest version is set as an initial value (i.e., a default value). For example, when the EDID file of the highest version is the 2.0 version, if the EDID file of the version 1.4 is initially set, the accessed external device may mistakenly think that the display device only supports the HDMI1.4 signal but not the HDMI2.0 signal, so that the display device can only output the HDMI1.4 signal but not the HDMI2.0 signal, and the display device cannot play the video picture with the optimal resolution. Therefore, the above phenomenon can be effectively avoided by setting the EDID file with the default value of 2.0 version and using the switching rule of decoding judgment and version degradation, so that each video signal can be played with the best resolution, such as 4K, 8K, and the like.

Exemplarily, when the display device decodes the video image of the video signal by using the EDID file of the highest version, the display device may specifically decode the video signal by a video decoder built therein, for example, analyze whether the format of the video signal is the video signal of the HDMI format, and acquire specific video image data, and the like. At this time, if the decoding is abnormal, step S120 is executed. Otherwise, if the decoding is successful, the displayed preset graph is directly hidden and the decoded video image is displayed.

In one embodiment, for the determination of the decoding abnormality, exemplarily, when the video decoder cannot recognize the video signal, that is, when the video decoder detects a parsing error, the display device determines that the decoding abnormality occurs at this time. And then, the EDID file version is degraded and switched, namely, the EDID file with the lower version is used for decoding. Or, when the video decoder identifies the video signal to the preset format, it determines that the decoding is abnormal, and at this time, it needs to switch to the EDID file with the lower version for decoding. For example, the currently loaded version 2.0 of the display device may be switched to version 1.4 for decoding if the video signal is identified as DVI format.

In another embodiment, when the video decoder parses out the video image, the video decoder may perform frame image capture analysis on the output video image, and compare the captured image with a pre-stored abnormal image to determine whether the decoding is successful. For example, these abnormal images may include, but are not limited to, a screen splash in order to see unclear contents at all, or appearance of monochrome images such as green and blue, etc., and these abnormal images may be stored in the server in advance. And when comparison is needed, comparing the output video screenshot image with the stored characteristic values of the abnormal images, and if the similarity between the characteristic value of at least one abnormal image and the characteristic value of the screenshot image exceeds a preset threshold, judging that the decoding at the moment is unsuccessful.

In consideration of the fact that the EDID file is manually switched by a user, some EDIDs are distinguished by an internal preset flag bit SCDC, and the EDID of the corresponding version is automatically switched according to the distinguishing result. However, this method has a problem in that when some external devices are connected, the SCDC flag may be faulty, and if the version is determined according to the flag and automatically switched, HDMI compatibility of the display device may be deteriorated. In addition, since the EDID switching execution needs a certain time to take effect, if the video decoder cannot accurately and timely judge the correctness of the video signal at the moment, an abnormal image of a period of time will appear, and accordingly, the user will see an abnormal picture of a period of time, which greatly reduces the user experience.

Therefore, in the embodiment, after the display device detects that the video signal is input, a preset graph is displayed to block an abnormal image which may appear. Generally, a picture displayed on a screen of a display device includes an image superimposed by a video layer, a graphics layer, a mouse layer, and the like, wherein the graphics layer is located above the video layer.

Illustratively, the preset graphics can be displayed by controlling the transparency of the engine of the graphics layer to be in a non-transparent state before the decoding is successful. After the decoding is successful, the display device can realize the hiding of the preset graph and the display of the video image by setting the engine transparency of the graph layer to be in a transparent state and setting the engine transparency of the video layer to be in a non-transparent state.

It is understood that the display time of the preset graphic may depend on the determination result of the decoding success. For example, when the decoding is determined to be successful, the displayed preset graph is hidden, otherwise, the preset graph is continuously displayed.

And step S120, if the decoding is abnormal, reducing the version of the EDID file for decoding until the video signal is successfully decoded, hiding the preset graph and displaying the decoded video image.

Exemplarily, after the decoding abnormality is determined, it indicates that the display device can only recognize the HDMI signal with the lower version at this time. Then, the display device will switch to the EDID file with the lower version for re-decoding until the video signal is successfully decoded. It is understood that the switching of the lower version can be determined according to actual requirements, and is not limited herein.

In an embodiment, when the versions are switched, a gradual reduction mode can be adopted, for example, when at least 3 versions exist, sequential decoding can be performed sequentially according to the sequence of the versions from high to low, so that preferential matching to the most suitable version can be ensured, and further, the display device can be ensured to perform playing display under the configuration of the best resolution ratio and the like. In another embodiment, for the EDID file with a lower version, random selection or selection of a more suitable version for switching according to a phenomenon or the like during decoding abnormality may be adopted.

In addition, considering that the display device is usually provided with an SCDC flag bit for distinguishing the signal type of the external device, in order to keep the same control logic as much as possible, when the version switching occurs, the SCDC is reset, so as to avoid that the state change of the SCDC cannot be identified, and further signal identification errors and the like are caused.

Optionally, after the display device successfully decodes the EDID file with the highest version or with a lower version, the display device may lock the version information corresponding to the current HDMI port, so that when a channel of a signal source is switched, for example, for a television, when switching between different signal sources such as ATV, AV, HDMI1, HDMI2, and the like is performed, the EDID data of the current HDMI port does not change, and thus when the display device enters a power-on state from a standby state, the speed of displaying a next video image may be increased.

As an alternative embodiment, as shown in fig. 2, before the display device receives the video signal input by the external device, the EDID adaptive method further includes:

step S90, when it is detected that an external device is connected to the display device through the HDMI port, device information of the external device is obtained.

Exemplarily, when the display device detects that an HDMI cable is inserted into an HDMI port, the external device may be identified through the HDMI cable. Generally, HDMI ports of display devices each support a CEC (consumer electronics control) function, and the CEC function allows a user to acquire device information of an external device currently connected to the HDMI port and to further control the external device using a CEC signal. The device information may include information such as a type and a name of the external device, for example, the display device may identify whether the external device is a DVD/VCD drive and a specific model thereof.

And step S100, inquiring whether the display equipment stores the equipment information or not, if not, judging that the external equipment is accessed for the first time, and loading the EDID file with the highest version by the display equipment.

It can be understood that, in order to control the corresponding external device, the display device generally stores the device information when acquiring the device information, so as to facilitate subsequent identification and control.

Exemplarily, when the device information of the external device is acquired, whether information consistent with the device information of the current device is stored in the external device can be inquired, and if not, the external device is judged to be the external device which is accessed for the first time, and at this time, the video decoding is performed by using the default EDID file with the highest version.

In order to shorten the waiting time of the user when the external device is accessed again, optionally, after the decoding is successful, the device information is stored for the external device which is accessed for the first time, so as to facilitate the display speed of the video and the like during the next access. As shown in fig. 3, the EDID adaptation method further includes:

step S130, storing the device information of the external device in association with the EDID file of the corresponding version when the decoding is successful.

Exemplarily, after the external device is judged to be accessed for the first time and decoding is successful, the device information of the external device and the EDID file data of the corresponding version can be stored in an associated manner.

In an alternative embodiment, the display device includes a plurality of HDMI ports for which the highest version of HDMI signals may be partially or fully supported. Exemplarily, when the external device is detected to be accessed, the current HDMI port number information is recorded and stored in association with the acquired device information of the external device.

And step S140, if the external device is identified to be accessed again, the display device decodes the EDID file which is directly matched with the version stored in the correlated way.

Exemplarily, for the external device that is accessed again, when the display device identifies the external device, the EDID file of the version stored in association with the external device may be directly loaded for decoding. For example, when the external device is inserted again, the display device will preferably query the associated storage data of the current HDMI port, and query other ports if the associated storage data does not exist, so as to determine the EDID file of the version that the external device matches best. At the moment, the judgment of the screen capture image for video decoding is not needed, so that the display time of the video picture is saved, the system resource is saved, and the waiting time of a user can be reduced.

Considering that a plurality of HDMI ports of the display device are usually provided, in this embodiment, each version EDID file corresponding to each HDMI port is separately stored, so that when the EDID file version of one of the HDMI ports needs to be switched, the setting of the other HDMI port locked as the corresponding version will not be affected.

In an optional implementation manner, when the display device is provided with a plurality of HDMI ports and the EDID file of each HDMI port is separately stored, in step S140, after recognizing that the external device is accessed again, the display device will determine whether the version of the EDID file loaded on the current HDMI port for access is consistent with the version of the EDID file stored in association.

If the video is consistent with the video, directly decoding the video; and if the EDID files are not consistent, switching the EDID file loaded by the current HDMI port into the EDID file of the version which is stored in an associated manner according to the EDID files of the versions which are stored separately, and then decoding. It should be appreciated that the preset graphics will always be in a display state until decoding is successful.

In addition, when a plurality of external devices with different models are accessed in a store or a user home, the EDID file is independently stored through each HDMI port, and the mutual influence of the compatibility of each HDMI port can be avoided.

According to the EDID self-adaption method, the video image decoding judgment is firstly carried out on the accessed video signals, the EDID file with the highest version is decoded by default, and when the decoding is abnormal, the version of the EDID file is reduced to decode until the decoding is successful, so that the self-adaption of the EDID files with different versions can be realized aiming at different conditions, the video can be played under matched configuration, and the version switching by a user is not required; meanwhile, in the process of image decoding and decoding judgment, a preset image is arranged on the image layer for display, and the video image is hidden when being normally displayed, so that the user can be effectively prevented from seeing an abnormal image before the video is normally played, the user experience is greatly improved, and the like.
