High-definition television

High-definition television (HDTV) provides a resolution that is substantially higher than that of standard-definition television.

HDTV may be transmitted in various formats:

The letter "p" here stands for progressive scan, while "i" indicates interlaced.

When transmitted at two megapixels per frame, HDTV provides about five times as many pixels as SD (standard-definition television).

History

The term high definition once described a series of television systems originating from August 1936; however, these systems were only high definition when compared to earlier systems that were based on mechanical systems with as few as 30 lines of resolution. The ongoing competition between companies and nations to create true "HDTV" spanned the entire 20th century, as each new system became more HD than the last. Ironically, in the beginning of the 21st century, this race has continued with 4k, 5k and current 8K systems.

Broadcasting

Broadcasting is the distribution of audio and/or video content to a dispersed audience via any electronic mass communications medium, but typically one using the electromagnetic spectrum (radio waves), in a one-to-many model. Broadcasting began with AM radio broadcasting which came into popular use starting with the invention of the crystal detector in 1906. Before this, all forms of electronic communication, radio, telephone, and telegraph, were "one-to-one", with the message intended for a single recipient. The term "broadcasting", borrowed from the agricultural method of sowing seeds in a field by casting them broadly about, was coined by either KDKA manager Frank Conrad or RCA historian George Clark around 1920 to distinguish this new activity of "one-to-many" communication; a single radio station transmitting to multiple listeners.

Over the air Broadcasting is usually associated with radio and television, though in practice radio and television transmissions take place using both wires and radio waves. The receiving parties may include the general public or a relatively small subset; the point is that anyone with the appropriate receiving technology can receive the signal. The field of broadcasting includes a wide range of practices, from relatively private exchanges such as public radio, community radio and commercial radio, public television, and commercial television.

Controversies

In March 2015, the Puthiya Thalaimurai office was attacked by a group of men who hurled two bombs into it; there were no casualties in the incident.

Two tiffin-box crude bombs were hurled at the office of Tamil news channel Puthiya Thalaimurai on Thursday morning (12 March 2015). The bombs exploded with a loud noise, but no one was injured nor was any property damaged. This attack was in response to the Puthiya Thalaimurai Channel that had planned to air a debate-programme on the thali or mangalsutra. The Hindu Munnani planned to protest outside the channel’s office against the programme on March 8, following which this attack took place. Activists of the group later attacked the channel crew which was to cover the protest. Ten members of Hindu Munnani were arrested.
