I had gone to Currys with my father as he was interested in replacing his dying CRT with a high definition TV. We were stood by the LG 32LX2R as it had by far and away the best Hi-Def picture in the store and I was explaining about scaling between the HD resolutions when a lurking Currys employee took the opportunity to pounce. "Have you heard of a superpixel?" "No." "Do you know how the TV displays the different resolutions." "It uses a scaler to..." "No, it uses a superpixel." "What's a superpixel?" He went on to explain to me that a superpixel is a pixel with smaller pixels built in to it. That it uses these smaller pictures to enable it to display resolutions that do not match its native display. Whilst this sounds great in theory, and seems to be logical, surely the complexity of such an arrangement, with millions of smaller pixels of different shapes and sizes would mean it would be far more simplistic - and cheaper - just to build a 3840x2160 resolution display that can cope with both 1280x720 and 1920x1080 without the need for pixel interpolation? Anyway, my father wasn't interested in the technical side of TV and started asking about Sky's HD service. The employee asked me what resolution I thought Sky would be broadcasting in: "1280x720 and 1920..." "1024 x 768" "That's not a High Definition resolution. It's.." "It's a computer monitor resolution. But its what they've said they'll be broadcasting in." Now I went on to say that I had been following Sky's HD press releases with great interest, as well as monitoring forums (this one in particular) - and no where I had I seen anyone say they were planning on using 1024x768 but he insisted it was what they would be using. I can't believe this is true, as the resolution does not use square pixels for a 16:9 picture, it would mean that broadcasts would have to be scaled twice (once to 1024x768 by Sky and then to whatever resolution the screen was that was displaying the image) - but I just wondered if anyone else had heard this. It must have come from somewhere, unless he was just speaking rubbish which I was beginning to think by the end of the conversation - however he did come across as more knowledgeable than your average Currys employee.
