1989 — HD TV

It was 1980 something, meaning it was the year 1989 and something called high-definition television. This can be done in digital or analog. You can use this in terrestrial, cable, satellite, Blu-ray discs and streaming videos.


This can be transmitted in a number of formats they are the following:

  • 720p 1280×720 per frame
  • 1080i 1920 x 1080i pixels
  • 1080p 1920 x 1080 p

The letter “p” standards for progressive scan, while “I” indicates interlaced.

First broadcast in the USA

Even if the HDTV system was developed in the ’80s but the first broadcast was in 1993 and field testing was completed in 1994. The following companies were involved with this and they were:

  • AT&T Bell Labs
  • General Instrument
  • Phillips
  • Sarnoff
  • Thomson
  • Zenith
  • Massachusetts Institute of Technology


Changed the way we viewed the TV, it consisted of Notation, the standard frame of field rates, types of media. It had a recording and compression for D-VHS, W-VHS and HDTV-capable digital video recorder, which DIRECTV, Skybox HD, Dish Network, Netflix, Windows Media Player, Xbox 360 and PlayStation 3.

In the United States, cable companies are required to provide customers who rent HD set-top boxes had to have a functional firewire. None of the direct broadcast satellite companies have offered this. Right now there is encryption called 5C and this can prevent duplication of content or simply limit the number of copies thus effectively denying most if not all fair use of the content.

This changed the way the TV viewing was viewed and made it so much better. Love the High Def.
