This example shows how to send 3 different VSIs. Two generic VSIs are sent prior to a 3D
VSI.
You first enable 3D VSI(128) infoframe and disable AUD, SPD, and AVI, MPG, GIFA, GIFB
and GAMUT.
IFTR 127 // enables repeating infoframes for GIFA (1), AVI (2), SPD (4),
AUD (8), MPG (16) GIFB (32), GAMUT (64)
IFTG 63 // enables (gates on) GIFA (1), AVI (2), SPD (4), AUD (8),
MPG (16) GIFB (32)
XGIF A 1 1 5 12FA001234 // sends 5 bytes in Vendor Specific Infoframe
XGIF B 1 1 5 56AB005678 // sends 5 bytes in Vendor Specific Infoframe
IFGU // iniates the sending of the infoframe gate commands
