From the Silicon Image
web site: "In addition to supporting advanced HDMI 1.3 video features, the SiI9134 supports 3D over HDMI in the HDMI 1.4 specification".
When the source reads the EDID of the display I think it's just up to software to recognize the 3D frame packed formats, as long as the hardware can be programmed to output them (which apparently the 9134 can).
In fact the more HDMI documentation I read the more convinced I am that most HDMI 1.3 receivers may only need a firmware update to work with 3D.
