HDMI Decoder
A Node object whose type is HDMI_DECODER. This object is only found on transmitters.
info
This node type is included in the response to a get edid command (in addition to get settings). However, in the response to a get edid command, the returned node only contains the configuration member, which itself only contains the edid member.
Configuration
HdmiDecoderNodeConfig{
"edid" : String,
"hdcp_support_enable" : Boolean,
"hdcp_22_support_disable" : Boolean
}
| Member name | Type | Description |
|---|---|---|
| edid | String | Configured EDID which will be seen by connected HDMI sources. The format of this member is a hexadecimal string with a length of 512 characters (which represents 256 bytes of data). Note: This member is not included in the response of a get settings command. It is, however, included in the response to a get edid command. |
| hdcp_support_enable | Boolean | Enable HDCP support. When disabled, the device reports to the HDMI source that it does not support HDCP. Note: Some laptops and other HDMI sources always encrypt video with HDCP when the connected sink supports it, even when not playing HDCP-protected content. Video from such a source cannot be shown on a monitor without HDCP support; disabling HDCP support in the transmitter device avoids this. |
| hdcp_22_support_disable | Boolean | Disable HDCP 2.2 support. When set to true, the device reports to the HDMI source that it only supports HDCP 1.4 (if hdcp_support_enable is also true). |
