The history of Internet Protocol Television (best IPTV) dates to the 1990s when it was barely thought to be possible that a TV program could viably be squeezed into an average telecommunication bandwidth of telephone cable to provide an acceptable quality of television service with about 200 Mbps. VOD services were highly made possible under two major technological developments- discrete cosine transform and asymmetric digital subscriber line.
In 1972, the television service was proposed by Sir Nasir Ahmed and then adapted into a viable motion-compensated DCT algorithm for a detailed video coding standard like the H.26* format.
In 1988 going forward, the MPEG format was adopted. The video compression format reduced the bandwidth amount needed to a TV signal, while the ADSL increased with data bandwidth that was sent to a copper telephone wire.
Over the years, ADSL increased the total bandwidth of the telephone line from the average 100kbps to about 2Mbps.
Similarly, DCT compression reduced the needed bandwidth of the digital television signal from 200 Mbps to 2Mbps. In 1990, the combination of ADSL technologies played the role of making it possible to implement VOD services at just about 2Mbps bandwidth.
Founding IPTV
The term IPTV originally appeared in 1995 during the launch of Precept Software by the prominent Judith Estrin. Assisted by Bill Carrico, the Precept quickly developed IP/TV, an internet video product compatible with Windows as well as Unix-based application, which quickly transmitted single as well as multi-source audio traffic, from low to enhanced DVD quality.
The software was documented by Steve Casner, Cha Chee Kuan, in addition to Karl Auerbach.
In 1998, Cisco Systems acquired Precept. The organization retained the prestigious IP/TV trademark before US West, a prominent telecommunications company, launched a viable IPTV service known as TeleChoice in Phoenix using a traditional terrestrial satellite. In 2008, there was the shutdown of the service.
Today, IPTV is known as one of the most revered television networks capable of delivering television contact over different Internet Protocol networks.
And unlike the downloaded media, the network provides users with the ability to stream source data progressively. For that reason, a client media player may start playing the content almost right away. This is defined as streaming media.
While IPTV utilized the internet protocol, it is definitely not limited to the television streamlined from Internet Television.
IPTV is primarily deployed in different subscriber-based telecommunication networks that have a high-access speed to channels into the end-user premises through set-top boxes and other additional customer-premises equipment.
Besides, IPTV is also used in media delivery in the corporate as well as private networks, where it is notable for its standardization process.
IPTV services can be classified into live and television media, with related interactivity and time shifting in media, such as catch up television replays and start-over.
Final Thoughts
Today, IPTV is widely used to distribute television media around businesses as well as commercial sites, whether as video on demand or just standard TV channels. A few examples of different types of commercial uses are such as offices, hotels, as well as sports stadiums, among others.
