CBS/Infinity and IBOC-AM?

Going from 720p to 1080i isn't that much of a difference, though you notice the difference in a side by side comparison. May be 4x the resolution of a VHS VCR (but not even quite that, at SP speed most get 270 lines), but not quite twice what regular broadcast NTSC resolution is. And NTSC STILL looks better because there's no artifacting in it, and no pixelization. Our satellite feed is so bad you can see artifacts in it every time there is a rapid pan or sweep, and when you have color gradients, you can see large amounts of pixelization in the transitions. I'll keep my analog, thanks, even if that means never watching OTA TV again. I think it is interesting that you bring up a similar point about digital video that I have been expousing about radio digital audio. It's all about trying to cram a digital signal bandwidth and digitized signal resolution in an analog spectrum space. This not unlike trying to put a square peg in a round hole. You can do it but the results are not pretty. -- Telamon Ventura, California |
