    Okay so we are heading for HDTV in 06 with SKY.

    And we know that different channels are broadcast in different aspect ratio 16:9, 4:3 and so on.

    So many large CRT TV have been able to automatically change the aspect ratio through scart (pin 8) line 23 etc.

    This feature has also been incorporated to large flat screen (but not all) and some of us may have encountered problems with this. Irrelevant.

    So my question to us all is this:

    HDMI or DVI for HDTV how are they going to detect the aspect ratio for different channels?

    Answers on a postcard please!

    They won't.

    If there was some common sense at Sky, since HD is all widescreen signals, all the 4:3 and letterbox stuff would be transposed into it's correct ratio for broadcast leaving no need to change ratio. If...

    If there is the tiniest bit of common sense then, just as it SHOULD have been with the standard resolution digital media (DVD, Freeview, $ky etc), the entire output should be configured for display, full screen, on a 16x9 device. That means including, in the broadcast, black side bars on 4x3 material.
