Embodiment 1

[0113] Such as Figure 4 As shown, it is a specific flow chart of an EDID processing method provided by an embodiment of the present invention, which specifically includes the following steps:

[0114] Step 41, acquire the audio capability set of the external device.

[0115] Specifically, the audio capability set of the external device may be acquired, but not limited to, through a consumer electronics control (Consumer Electronics Control, CEC) module in the display device.

[0116] Step 42, according to the audio capability set of the external device, it is judged whether the external device supports the ATMOS capability. When the judgment result is yes, continue to execute step 43, and when the judgment result is no, the flow ends.

[0117] Specifically, whether the external device supports the ATMOS capability can be determined by determining whether the audio capability set of the external device includes an identifier indicating that it supports the ATMOS capability. ...

Embodiment 2

[0134] Such as Figure 5 As shown, it is a specific flowchart of another EDID processing method provided by the embodiment of the present invention, which specifically includes the following steps:

[0135] Step 51, acquire the audio capability set of the external device.

[0136] Specifically, the audio capability set of the external device may be acquired, but not limited to, through the CEC module in the display device.

[0137] Step 52: According to the audio capability set of the external device, it is judged whether the external device supports the ATMOS capability. When the judgment result is yes, continue to execute step 53, and when the judgment result is no, the flow ends.

[0138] Specifically, whether the external device supports the ATMOS capability can be determined by determining whether the audio capability set of the external device includes an identifier indicating that it supports the ATMOS capability.

[0139] Step 53, sending a second instruction for ad...

Embodiment 3

[0152] Such as Image 6 As shown, it is a specific flowchart of another EDID processing method provided by the embodiment of the present invention, which specifically includes the following steps:

[0153] Step 61, acquire the audio capability set of the external device.

[0154] Specifically, the audio capability set of the external device may be acquired, but not limited to, through the CEC module in the display device.

[0155] Step 62: According to the audio capability set of the external device, it is judged whether the external device supports the ATMOS capability. When the judgment result is yes, continue to execute step 63, and when the judgment result is no, the flow ends.

[0156]Specifically, whether the external device supports the ATMOS capability can be determined by determining whether the audio capability set of the external device includes an identifier indicating that it supports the ATMOS capability.

[0157] Step 63, deinitialize the HDMI module of the d...

Abstract

Disclosed are an extended display identification data (EDID) processing method and apparatus for dynamically refreshing EDID. The method comprises: when an external device connected to a display device supports a Dolby Atmos (ATMOS) capability, controlling a high definition multimedia interface (HDMI) module of the display device, so as to disconnect the display device from the external device; updating EDID of the display device to obtain updated EDID; loading the updated EDID to the HDMI module; and controlling the HDMI module, so as to reconnect the display device to the external device.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for processing Extended Display Identification Data (EDID). Background technique [0002] Dolby Atmos (Dolby Atmos, also referred to as ATMOS) is a new cinema audio platform developed by Dolby Laboratories and released on April 24, 2012. It breaks through the concept of 5.1 and 7.1 channels in the traditional sense, and can combine video content to present dynamic sound effects. Different from the previous audio signal that controls one side of the theater to produce the same sound, it can make multiple speakers on one side produce different sounds one by one, creating a more realistic sound effect from far to near; with the addition of speakers on the ceiling, it can realize Surrounded by the sound field, it shows more sound details and enhances the audience's viewing experience. [0003] Currently, a display device generally includes a High ...
