588 Appendix A Command Reference
Class InfoFrame Generator (IFG) parameter
Description Writes generic InfoFrame packet data. This allows you to emulate any InfoFrame type
(including vendor-specific).
Note: The HDMI specification (section 5.2.3.2) requires that an HDMI packet must be
transmitted at least every two VSYNC periods, or the receiver will drop out of HDMI mode.
A Generic InfoFrame packet can be used for this purpose by enabling its repeat bit (see the
IFTR command).
