Description
Syntax
Parameters
Command Example
XAUD
Enables you to send
specific parameter
values of the AUD
infoframes out the
HDMI output
independent of the
HDMI audio stream.
XAUD:audparameter <value>
Where audparameter is one of the values identified
below and value is an allowed value associated with
the parameter provided in CEA-861-E.
CA – Channel assignment. Sets the channel
assignment value or retrieves the value transmitted.
CC – Channel count. Sets the channel count value
or retrieves the value transmitted.
CT – Audio coding type. Sets the audio coding type
value or retrieves the value transmitted.
SS – Sample size. Sets the sample size value or
retrieves the value transmitted.
SF – Sampling frequency. Sets the sampling
frequency value or retrieves the value transmitted.
DMI – Down-mix inhibit. Sets the down-mix inhibit
value or retrieves the value transmitted.
LSV – Level shift value. Sets the level shift value or
retrieves the value transmitted.
PBL – LFE playback level. Sets the LFE playback
level or retrieves the level transmitted.
CSUM – Checksum. Sets or gets the checksum
value for the corresponding InfoFrame.
To set the channel count to 3:
XAUD:CC 2
IFGU
To set the sampling size to 24:
XAUD:SS 3
IFGU
To return the value of the
channel count parameter type:
XAUD:CC?
XHVI
Enables you to send
specific parameter
values of the Vendor
Specific infoframe out
the HDMI output
independent of the
HDMI stream.
XHVI:hviparameter <value>
Where hviparameter is one of the values identified
below and value is an allowed value associated with
the parameter provided in CEA-861-E.
HVF – HDMI Video Format field. Values: 0 = no info,
i.e. 2D; 1 = 4Kx2K; 2 = 3D.
HVIC – HDMI Video Identification Code (VIC). Sets
VIC for 4Kx2K use.
H3DS– HDMI 3D structure. Sets the 3D structure
indication.
3DMG – 3D metadata present gate. Indicates
whether 3D metadata is present or not present.
3DED – 3D External data.
LEN – HDMI VSIF length in bytes.
CSUM – Checksum. Sets or gets the checksum
value for the corresponding InfoFrame.
To enable 3D:
XHVI:HVF 2
IFGU
To indicate that 3D metadata is
present:
XHVI:3DMG 2
IFGU
To query if 3D metadata is
present:
XHVI:3DMG?
