Video SEND_COMMANDs (Transmitters), continued
?VIDIN_STATUS
Requests the status of the video input
on the Transmitter.
Important:
Send to Port 7 for digital video and Port 8 for analog video.
Syntax:
SEND_COMMAND <DEV>,"'?VIDIN_STATUS'"
Valid responses:
status = NO SIGNAL, UNKNOWN SIGNAL, VALID SIGNAL
Example:
SEND_COMMAND dvTX,"'?VIDIN_STATUS'"
Returns a COMMAND of the form:
VIDIN_STATUS-<status>
?VIDIN_FORMAT
Requests the video format on the
Transmitter.
Note:
When this query is sent to port 7,
the response reflects the format of
digital content if there is any digital
content. If there is no digital content, it
will report UNKNOWN.
Important:
Send to Port 7 for digital video and to Port 8 for analog video.
Syntax:
SEND_COMMAND <DEV>,"'?VIDIN_FORMAT'"
Valid responses:
format (Port 7) = HDMI, DVI
format (Port 8) = COMPONENT, S-VIDEO, COMPOSITE, VGA
Example:
SEND_COMMAND dvTX,"'?VIDIN_FORMAT'"
Returns a COMMAND of the form:
VIDIN_FORMAT-<format>
VIDIN_FORMAT
Sets the video format on the
Transmitter.
Important:
For RGsB video signals,
you must use the VIDIN_FORMAT
command and set the “valid
responses” format to VGA.
Important:
Send to Port 8 for analog video.
Syntax:
SEND_COMMAND <DEV>,"'VIDIN_FORMAT-<format>'"
Valid responses:
format = COMPONENT, S-VIDEO, COMPOSITE, VGA
Example:
SEND_COMMAND dvTX,"'VIDIN_FORMAT-COMPONENT'"
Note:
VIDIN_AUTO_SELECT must be set to
“
DISABLE
”
for a
VIDIN_FORMAT command to take effect.
?VIDIN_RES_AUTO
Requests the setting for the Auto mode
on the Transmitter (Enable or Disable).
Note:
Send to Port 8.
Syntax:
SEND_COMMAND <DEV>,"'?VIDIN_RES_AUTO'"
Example:
SEND_COMMAND dvTX,"'?VIDIN_RES_AUTO'"
Returns a COMMAND of the form:
VIDIN_RES_AUTO-<ENABLE|DISABLE>
VIDIN_RES_AUTO
Enables or disables the Auto mode
(for automatically determining the
resolution) on the Transmitter.
Note:
Send to Port 8.
Syntax:
SEND_COMMAND <DEV>,"'VIDIN_RES_AUTO-<ENABLE|DISABLE>'"
Example:
SEND_COMMAND dvTX,"'VIDIN_RES_AUTO-ENABLE'"
?VIDIN_RES_REF
Requests the resolution and refresh
rate of the video through the
Transmitter.
Important:
Send to Port 7 for digital video and Port 8 for analog video.
Syntax:
SEND_COMMAND <DEV>,"'?VIDIN_RES_REF'"
Valid responses:
• horizontal = An integer value representing the horizontal.
• vertical = An integer value representing the vertical. May have an
additional qualifier such as “i” or “p”.
• rate = An integer value representing the refresh rate.
Example:
SEND_COMMAND dvTX,"'?VIDIN_RES_REF'"
Returns a COMMAND of the form:
VIDIN_RES_REF-<horizontal>x<vertical>,<rate>
Note:
If no signal is connected to the port being requested, then the response
will be
VIDIN_RES_REF-0x0,0
.
Note:
If analog video is currently routed and the resolution of the digital video
(Port 7) is requested, then the response will be
VIDIN_RES_REF-0x0,0
even if digital video is present.
