I wanted to send a signal with more than 8 bit resolution only via analog, not digital (because today digital equipment does not count with more than 8 bit), however the DVI should allow more than 8 bit via dual-link (I'm not sure how much is that standard, but it was mentioned on the webpage i've recently read - url is somewhere here in the list). > > Which brings up: has HDMI been considered? > >> head3: SVHS / component video >> (low speed 10bit DAC for SD television quality) > > I suspect you mean s-video rather than svhs. > You're right, sorry for mis-naming the thing. About HDMI: it (probably) does not support more than 8 bits since inside it is as much as a single-link DVI (with different mechanical solution). In case that you won't use HDCP (DRM) you need only a cable.
