WHAT IS TELEVISION?WHAT IS TELEVISION?

TV is a telecommunication medium that is used for transiting and

receiving moving images and sound. Television can transmit images that are

monochrome (Black & White), in color or in 3 Dimensions.

Commercially available since the late 1920s but in extremely limited

numbers, the television set has become commonplace in homes by 1950s. In the

Mid 1960s Color TV become widely available.

The availability of storage media such as video cassettes (mid-

1970s), laserdiscs (1978), DVDs (1997), and high-definition Blu-ray Discs (2006)

enabled viewers to use the television set to watch recorded material such as

movies and broadcast material. Internet television has seen the rise of television

programming available via the Internet through services such as iPlayer, Hulu,

and Netflix.

HISTORY OF TELEVISIONHISTORY OF TELEVISION

JOHN LOGIE BAIRD

Born in 14 August 1888 Scotland

Died at 14 June 1946 (aged 57)England

Known for Inventor of television

John Logie Baird

John Logie Baird was a Scottish engineer, innovator

and inventor of the world's first television the first publicaly

demonstrated color television system; and the first purely

electronic color television picture tube.

He demonstrated the world's first colour transmission

on 3 July 1928, using scanning discs at the transmitting and

receiving ends with three spirals of apertures, each spiral with a

filter of a different primary colour; and three light sources at the

receiving end, with a commutator to alternate their illumination.

In 2009, 78% of the world's households owned at least one television

set, an increase of 5% from 2003. The replacement of cathode ray tube

(CRT) technology with various flat-panel televisions using LCD, plasma,

or LED screens was a major change in how television sets operated. In 2013,

87% of televisions sold had color LCD screens.

Color TV is part of the history of television, the technology of

television, and practices associated with television's transmission

of moving images in color video.

In its most basic form, a color broadcast can be

created by one each in the three colors of red, green and blue

(RGB). When displayed, these images will companied

together to produce a full color image as seen by the viewer.

It was introduced in the US in 1953

A standard television set comprises multiple internal electronic circuits,

including circuits for receiving and decoding broadcast signals. A visual display

device which lacks a tuner is properly called a video monitor rather than a

television.

The most common usage of television is for broadcast television, which

is modeled on the radio broadcasting systems developed in the 1920s.

Broadcast television uses high-powered radio-frequency transmitters

to broadcast the television signal to individual television receivers. The broadcast

television system is typically disseminated via radio transmissions on channels in

the 54–890 MHz frequency. In addition to over-the-air transmission, television

signals are also distributed by cable and satellite systems.

DLP – Digital Light Projection




CRT – Cathode Ray Tube Televisions

One of the major drawbacks to CRTs are their size and weight.They are extremely long-lasting and reliable. Lifespan: Up to 20 Years. Energy Usage: High, when compared to newer models of the same size. Lower picture quality. Typical Screen Sizes: 12” to 38”.

RP – Rear Projection Televisions

Rear projection TVs were the first “big screen” TVs. The major drawback to RP TVs is that they require expensive maintenance. Good picture quality and above-average sound quality. Viewing Angle: Very narrow. The picture fades badly as you move to the side. Energy Usage: Very low. They use about half the energy of LCD and plasma TVs of the same size. Typical Screen Sizes: 42” to 80”.

DLP – Digital Light Projection Televisions

They had only been on the market for a short time before the ultraslim flat panels came out. Lightweight and thin. Energy Usage: Low. They use less energy than LCD and plasma TVs of the same size.Typical Screen Sizes: 44” to 65”.


Liquid-crystal-display televisions (LCD TV) are television sets that use LCD display technology to produce images. LCD televisions are thinner and lighter than cathode ray tube (CRTs) of similar display size, and are available in much larger sizes.


A plasma display panel (PDP) is a type of flat panel display common to large TV displays 30 inches or larger. They are called "plasma" displays because the technology utilizes small cells containing electrically charged ionized gases, or what are in essence chambers more commonly known as fluorescent lamps.

An LED-backlit LCD display is a flat panel display which uses LED backlighting instead of the cold cathode fluorescent (CCFL) backlighting used by most other LCDs. LED-backlit LCD TVs use the same TFT LCD (thin film transistor liquid crystal display) technologies as CCFL-backlit LCD TVs.


The term broadcasting refers to the airborne transmission of

electromagnetic audio signals (radio) or audiovisual signals (television) that are

readily accessible to a wide population via standard receivers.

BROADCAST PROGRAMMINGBROADCAST PROGRAMMING

From the earliest years of broadcasting, if you had a microphone, a

music player and a transmitter, you had yourself a radio broadcasting station

your broadcasting hours were limited only by your available staff.

With our 'Digital Radio System' (DRS) computer, could transmit

programs completely unattended continuously for up to 7 days!

The pre-recording can be Done through DRS.

COMPUTERS IN BROADCASTINGCOMPUTERS IN BROADCASTING

'DRS' computers had the ability to record and playback simultaneously -

even playing back a live program before its recording is complete! This would be

most useful if ever we decided to rebroadcast a program originating. Our DRS

system can be used to pre-record and playback a hosted program, or 'capture' music

directly from CDs at a speed up to 40 times faster than normal playback - this is how

we provide our 'Overnight Music'.

For example, suppose we were offered a live program from Kochi such as the final

judging of Idea Star Singer of the Year, but it started at 6.30pm imagine show

telecast on7 pm. We would be able to delay such a broadcast by 30 minutes, even

while it is streaming in to us! This would be done by using several manually operated

tape recorders!

WEBCAM MONITOR FOR INTERNET BROADCASTINGWEBCAM MONITOR FOR INTERNET BROADCASTING

One common use for webcams is to see what's happening at your home, or

your business, when you're away. Webcam Monitor makes it easy to broadcast

video from one or more cameras. In order to see a Webcam Monitor video broadcast

from outside your network, you need to instruct the router to let certain requests into

your network from the Internet.

The most common type of computer network today uses the Internet

Protocol, (“IP”). There are two types of IP addresses - Private and Public. The

numbers that begin with 192.168.x.x are called Private or Non-Routable IP

addresses - and they are only useful inside your network. So your desktop computer

might be 192.168.2.2, and your laptop might be 192.168.2.3.

Public IP addresses are assigned by your Internet Service Provider.
