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.

• A standard for communicating data in packets
over a digital network.
