Table 11-1: List of Commands (alphabetical) – For Testing HDMI Sink Devices
Command Description
HSPG Sets enable gate of
the horizontal sync
pulse.
IMGL Loads an image
(pattern).
IMGU
Activates an image
that has been loaded
and queries for the
currently active image.
NBPC Sets or queries the
number of bits per
component. Applies
only to HDMI
PRAT? Queries the pixel rate
of the outgoing HDMI
format.
RGBW
Sets RGB values on
with Raster and
Window test patterns
SCAN
Defines whether the
active timing is
progressive or
interlaced or queries
the state of the active
timing.
SIRE Sets IRE levels for
certain images:
Window1/2, Raster,
Flat_Wht/Grn/
Red/Blu/Cyn/Mag/Blk
SSST Sets or queries the
sync type. Applies only
to analog outputs.
VRES Sets or queries the
vertical resolution of
the active timing.
Express in number of
lines.
