What are the two major types of HDTV?
The two major types of HDTV are interlaced and progressive. The suffix will have either an “i or p” indicating interlaced or progressive (non-interlaced). Interlaced is two frames or pictures alternating to form the display viewed. The progressive is both frames shown at the same time sharpening the picture. Many broadcasters offer a combination of SD (Standard Digital) (480i) and HD (720p or 1080i). The nature channels like to use 1080i as it delivers the highest quality for slow-moving pictures. On the other hand, many sporting events are broadcast in 720p for the superior quality of high-speed pictures.
