Octopuses Notice and Prefer High-Def TVs, Unlike Dad

Extremely important research is being done in Australia right now, and it's yielding extremely important results: octopuses are officially more technically discerning than about 1/5th of the American public.

Macquarie University's Renata Pronk has discovered that the animals, despite probably not even seeing color, were much more interested in HDTV than in SD, though not for the reasons you might think. The preference, Pronk thinks, comes down to hertz, not pixels. Because of a quirk of their sense of sight, Octopuses may see SDTV as a series of jerky still images, needing the 50/60hz of an HDTV to get the fluid effect that humans enjoy in both cases.

With Christmas fast approaching, this could be the evidence you need to convince a stubborn friend or loved one to finally make the switch. A suggestion: look them in the eyes and slowly, earnestly say, "You're not an octopus. You're better than an octopus." You can't go wrong with that kind of flattery.

DISCUSSION

Well, anyway, there is for all practical purposes no visual difference between 1920x1080i and 1920x1080p, and I'm even talking "visual information." Especially if you're talking 1080i60 versus 1080p24, the data rates are much the same. Most of the sources we see at 1080i are heavily compressed (broadcast) sources, so you might think 1080i is "worse" or "bad." An uncompressed 1080i versus uncompressed 1080p24 is going to be undiscernably different except in very unusually high-panning, high-motion scenes (as long as you have a capable de-interlacer).

Now, talk amongst yourselves.
