Although to many of us the progression from ‘standard definition’ TV and various levels of high-definition at 720p or better seemed to happen smoothly around the turn of the new century, there was a far messier technological battle that led up to this. One of these contenders was Enhanced Definition TV (EDTV), which was 480p in either 4:3 or 16:9, as a step up from Standard Definition TV (SDTV) traditional TV quality. The convoluted history of EDTV and the long transition to proper HDTV is the subject of a recent video by [VWestlife].
One reason why many people aren’t aware of EDTV is because of marketing. With HDTV being the hot new bullet point to slap on a product, a TV being widescreen was often enough to market an EDTV with 480p as ‘HD’, not to mention the ‘HD-compatible’ bullet point that you could see everywhere.
That said, the support for digital 480p and ‘simplified 1080i’ signals of EDTV makes these displays still quite usable today, more than SDTV CRTs and LCDs that are usually limited to analog signals-only at regular NTSC, PAL or SECAM. It may not be HD, but at least it’s enhanced.
