...NTSC, PAL and SECAM are analog standards, and as such you will not find much direct reference to them in the HDMI Spec. What you will find is that most resolutions are qualified as being @59.94/60Hz or @50Hz, and the general comment is that HDMI devices should output/input the same class of resolutions/framerates that the same device would output/input on component video or DVI. In short, if all your analog outputs have European DTV resolutions @50Hz, thats what you should expect in your HDMI output too. If all your analog outputs have US DTV resolutions @59.94/60Hz, thats what you should expect on HDMI too. The only mandatory cross-over is that @50 sink devices need to be able to accept 640x480 @ 59.94/60 (the fallback mode that so many video standards require)...
