Regular Chad’s News readers are now familiar with the various HDTV modes (e.g., 720p, 1080i, etc.). And I’ve always associated larger picture sizes with higher quality. I was surprised, therefore, to read the linked article which contends that this is not necessarily the case—that the quality of the signal has little to do with the number of pixels. It turns out that broadcasters compress the digital signal to conserve bandwidth, and the compression algorithm is lossy. The compression reduces the quality of the picture regardless of the number of pixels, and if used “overzealously,” it will make a visible difference.
