Does digital cable produce a better picture on an HDTV vs. a standard television? (no HD package)?

megapixel camera vs analog camera image

BDS

With digital cable service, would the connection to an HDTV provide a better picture than if it was hooked up to a standard def tv? I am referring to just regular digital cable, not the HD package.

Answer
It depends.

Case 1, Widescreen Movie; An HDTV is better suited for widescreen because of the aspect ratio - the black bars at the top and bottom (for 1.85:1 and 2.35:1) will be much less apparent on an HDTV set.
Case 2, Screen Size; An HDTV set usually is larger than a standard def set so without a higher resolution image (from HD) the picture will appear worse. This is similar to megapixels on a camera; you can get by with a 4x6 print with a few megapixels, but when you blow up the image you see all the block detail from the pixels.

Anyway, I know of no regulations on the cable or satellite industries to control quality of digital broadcast. There are standards for signal level and quality for analog broadcasts. The industries compress the video content using digital compression techniques and fit more content on for you to enjoy.

Analog is probably a better quality, but an HD set is good to have for several reasons especially if you feed it HD content.

Digital SLR pixels vs. regular digital pixels?

Qwerty

Ok, so I'm thinking about upgrading to a digital SLR camera from my 10megapixel bridge camera, and I was looking at getting the Nikon D40, but it's only 6.1 megapixel. Will this make a big difference in terms of image quality, or will the larger CCD make up for it somehow? Please explain how it works.

Thanks in advance

Answer
Mega pixels is basically a myth. More is not necessarily better. What matters far more is the size of the pixels. The sensors on most DSLR's are nearly 15 times larger than the sensors on point and shoot cameras. Therefore the pixels are 15 times larger. Larger pixels deliver better detail and less noise than smaller ones. Point and shoot camera with tiny sensors packed with lots of pixels actually generate more heat and noise than they would if they had fewer pixels.

Enough about pixels and sensors. The image quality of even the cheapest DSLR will be far greater than even the best point and shoot. The reasons are that DSLR's have much better optics, much larger sensors, better faster processors and much better analog to digital converters.
