Telecommunication is the extension of communication over a distance. The elements of a telecommunication system are a transmitter, a medium (line) and possibly a channel imposed upon the medium and a receiver. The transmitter is a device that transforms or encodes the message into a physical phenomenon; the signal. The transmission medium, by its physical nature, is likely to modify or degrade the signal on its path from the transmitter to the receiver. The receiver has a decoding mechanism capable of recovering the message within certain limits of signal degradation. In some cases, the final “receiver” is the human eye and/or ear (or in some extreme cases other sense organs) and the recovery of the message is done by the brain. One of the roles of the telecommunications engineer is to analyse the physical properties of the line or transmission medium, and the statistical properties of the message in order to design the most effective encoding and decoding mechanisms. Telecommunication can be point-to-point, point-to-multipoint or broadcasting, which is a particular form of point-to-multipoint that goes only from the transmitter to the receivers.

The broadband technology in its inception has further ‘broaden and widen’ the so-called “information superhighway” allowing smooth traffic of all medium of data (voice, audio, graphics and video) with freer and faster access from their source to their destination. Major players of this technology are the Telecom and Digital Broadcasting Service (DBS) providers.
The broadband technology has created a lot of multiplier effects in the adjoining ICT technologies (Information, Communication and Telecommunications technologies) used in delivering service to their teeming subscribers. The main stream of this arrangement are the copper lines, cable-, modems and telephone-network upgrades are proceeding at varying speeds, depending on the company.
The responsibility lies on service providers to iron out any number of technological issues with the economies of scale in the broadcast and transmission distribution network before they can provide seamless, bug-free service in line of this new dynamic technology.
This consideration and the attendant deployment of the arrived business decisions on the chosen technology gave rise to digital satellite broadcasting and the rapid expansion of voice over IP (VoIP) technologies.
Also it further the growth of Wireless service providers, whose sector found the ways to speed the upstream, or return-path, delivery of data (data, voice and video)making the choice and option more attractive Continue reading »
The television, it is safe to say, has become firmly entrenched in modern day society. No other medium is as widely used – television ranks first, with computers and the radio coming second and third respectively – or appeals to such a wide range of age groups and interests. It is no surprise then that the broadcasters have worked hard to ensure television continues to provide a relevant level of service to its viewers.
One of the most notable developments in the history of the television is digitisation. No longer as limited by size, broadcasters have found that by switching to digital the channels take up less bandwidth, meaning it’s possible to provide more content within the same space. Not only that, but they can also offer the viewer additional multi-media services, which has led to a much greater level of viewer interactivity.
According to the latest statistics, seven countries, including America, Germany and Luxembourg have already changed from analog terrestrial broadcasting to digital transmission. Many others, like the UK and Australia are currently in the process of switching, and it is expected that most other countries will follow suit within the next decade.
This switch from analog to digital highlights the fundamental change television has undergone since its first appearance in the early 1900s and serves to show how the relationship between broadcaster and viewer has altered. Indeed, in contrast to merely being broadc Continue reading »
