It is hard to image a WORSE sports TV format than 50 interlace. I have
never seen a fast sporting event look good on 50i, especially HDTV 50i. On
a large HDTV screen everything 50i looks bad, interlace problems, coding
problems (constrained channel where interlace is harder to code cleanly).
This is why 720p50 or 720p60 are the standards for the US and NATO country
military systems. Interlace is terrible for dynamic motion events where
the pixels matter (I could care less about selling soap on CBS - one can
use whatever you want for that need). Where the picture is IMPORTANT you
have to use progressive scan imaging at high temporal rates.
