Video Send_Commands (Cont.)
@VDD
Sets the video
setting for auto-
detection or man-
ual detection of
the video stan-
dard.

ward Mode Alog-

Syntax:
"'@VDD <ASCII settings for video detection>'"
Variables:
ASCII detection settings = 1: Auto-detect video input
2: Manual set NTSC
3: Manual set PAL
4: Manual set SECAM
Example:
SEND_COMMAND TP,"'@VDD 3'"
Detects only PAL.
The algorithm creates independent vertical sync 60 Hz/50 Hz (NTSC/PAL or SECAM) tim-
ing, ignoring the sync from the VCR. During fast forward on many VCRs, the vertical sync
timing increases by 8 Hz, thus, causing the video pictures to freeze on our digital hard-
ware.
Syntax:
"'@VFF <ASCII video fast forward settings>'"
Variables:
ASCII video settings = 0: Normal
1: On
2: Off (required for Tanberg's non-interlacing equipment)
Example:
SEND_COMMAND TP,"'@VFF 2"
Turns the algorithm Off.
Syntax:
"'@VHU <ASCII setting for Hue>'"
Variables:
ASCII hue setting = 0 (min) - 255 (max)
Example:
SEND_COMMAND TP,"'@VHU 128'"
Sets video hue to 128.
Resets the following video attributes to their default settings:
Brightness, Contrast, Saturation, Hue, Interlace
Syntax:
"'@VSD'"
Example:
SEND_COMMAND TP,"'@VSD'"
Resets the video defaults.
Syntax:
"'@VST <ASCII setting for Saturation>'"
Variables:
ASCII saturation setting = 0 (min) - 255 (max)
Example:
SEND_COMMAND TP,"'@VST 128'"
Sets video saturation to 128.
