Early TV was mechanical, using a spinning disk to scan the image. A 30-line scan was common, but there were few standards.
Modern TV is electronic. A 405, 525, 625 or 800 line standard has been common.
Digital TV uses compression techniques to put more signal into the bandwidth, allowing for higher definition.
