History of Television

• John Logie Baird (August 13, 1888 – June 14, 1946)

a Scottish engineer, is known as the inventor of the

first working television system.

• In his first attempts to invent television, Baird

experimented with the Nipkow disk and

demonstrated that a semi-mechanical analogue

television system was possible with the transmission

of a static image of a ventriloquist's dummy

in London in February 1924.

History of Television

• Although the development of television was the

result of work by many inventors (including Baird,

Paul Gottlieb Nipkow and Boris Rosing) Baird is

one of its foremost pioneers.

• He is generally credited with being the first person

to produce a discernible television image, and went

on to produce other advances in the field.

History of Television

• Experiments in television broadcasting were initiated

during the 1920s in the US and Europe.

• These experiments used a mechanical disc that did

not scan a picture rapidly enough.

• In 1923, however, came the invention of the

iconoscope, the electric television tube.

• The inventions of the kinoscope or picture tube, the electronic camera and TV home receivers arrived in rapid succession during the next few years.

• By the 1930s, the National Broadcasting Corporation (NBC) had set up a TV station in New York and BBC a TV station in London offering regular telecast programmes.

History of Television

• By the late 1940s and early 1950s, television had become a regular feature of life in most developed countries.

• 1962- The Age of Satellite Communication

• 1970s- more sophisticated transmission employing optical cable fibre and computer technology invented.

History of Television

• The early television broadcasts were all black and white.

• The first successful programme in colour was

transmitted by Columbia Broadcasting System (CBS) in

USA in 1953.

• The television set became one of the important mediums

of entertainment with the advent of several popular

shows. Television gradually matured as a medium during

the next two decades.

• From being „radio with pictures‟ it acquired a unique style

of its own. As a result of this, this phase is often called

the „golden age‟ of television.

History of Television

• In today’s world, television has become one of the most powerful means of mass communication.

• It can impart education, information and entertainment.

• Television has become an integral part of our lives.

IPTV refers to a TV connection that has

capacity to transmit all broadcast channels,

Movies on Demand, Customer Live Request

etc. through existing telephone line in the form

of IP packets.

IPTV

• Internet Protocol Television describes a system

where digital television service is delivered to

subscribers using Internet Protocol over a broadband

connection.

• This service is often provided in conjunction with

Video on Demand and may also include Internet

services such as Web access and VoIP, called Triple

Play and typically supplied by a broadband operator

using the same infrastructure.

• A simpler definition would be television content that,

instead of being delivered through the traditional

format, is received by the viewer through the

technologies used for the Web.

Packet Switched Network

• Network technology that breaks up a message into small

packets for transmission.

• Unlike circuit switching, which requires the establishment

of a dedicated point-to-point connection, each packet in a

packet-switched network contains a destination address.

• Thus, all packets in a single message do not have to travel

the same path.

• As traffic conditions change, they can be dynamically

routed via different paths in the network, and they can

even arrive out of order.

• The destination computer reassembles the packets into

their proper sequence.

• Network protocols such as IP and IPX were designed for

packet-based networks.

Drivers Behind IPTV Deployment

For circulation to CTO Trainees only

The bundling of voice, high-speed data and IP-

TeleVision (IPTV) is becoming the focus of

Telco's‟ consumer strategy.

This “triple play” strategy is emerging because,

offering video service presents the largest

opportunity to increase revenue.

Why it is so important now for Telco's?.....

Telco wire line cash flow will continue to

decline if new revenue opportunities, such as

IPTV, are not embraced.

For a Telco with an existing copper Infrastructure,

offering triple play service across an 18 Mbps

connection yields $195 million in additional revenue

in Europe.

Why it is so important now for Telco's?

• A standard for communicating data in packets

over a digital network.
