2. WHAT IS BROADCAST MEDIA?
• The term 'broadcast media' refers to a very wide range of
different communication methods such as television, radio,
newspapers, magazines and any other materials supplied by
the media and press.
• It's
primary target are usually web surfers and people who
watch television and listen to the radio on a daily basis.
3. TYPES OF BROADCAST MEDIA
• Speeches
• Documentaries
• Interviews
• Advertisements
• Dailynews
• Financial markets information
• Short video clips
• Tutorials
• Podcasts
4. DIGITAL RADIO
• Digitalradio works by turning both sound
and data into digital signals at transmission,
and then decoding them at the other end
using digital radio receivers.
5. DIGITAL RADIO BENEFITS
• The result is CD-quality sound music.
• Digitalradio receivers have built-in technology that cleans and
filters transmissions, reducing interferences (AM/FM radio
quality can be broken from interference caused by signals
bouncing off walls, buildings, hills and other structures).
• Data now able to be sent as part of the signal, digital radio
receivers with LCD screens can also give listeners information
such as song names, news, weather and much more, all being
adjustable by the user.
6. DIGITAL RADIO BENEFITS
• Digitalradios are also easier to tune. Instead of struggling with
a dial to find the strongest frequency for a station, listeners are
able to choose a station by name from a menu, with the digital
radio automatically locking on to that signal at a push of a
button.
• Digitalradios with hard drives will also allow people to pause
live radio transmission or rewind, just like digital set top boxes
or DVD recorders with hard drives do for digital television.
7. DIGITAL TELEVISION
• Digital Television
(also referred as DTV) is a kind of new
broadcasting technology that totally changed our viewing
experience of television.
• Oldest and commonly used method or receiving DTV is using
an antenna to receive the signal.This way is known as Digital
Terrestrial Television (DTT). With that use of DTT, viewers are
limited to watch whatever channels the antenna picks up.
Signal quality will also vary as antennas are sometimes placed
in weird places.
8. DIGITAL TELEVISION
• Most people today will pick up digital television via a set-top
box, which decodes the digital signals into signals that analog
televisions can understand. These types of TVs are known as
DTV monitors (HD monitors in the case of HDTV).
• However, a slowly growing number of TV sets with integrated
receivers are already available, known as iDTVs.
9. DIGITAL TELEVISION
• Other ways to receive DTV include digital cable and digital
satellite. Another way is IPTV, that is receiving TV via Internet
Protocol with guaranteed quality of service (QoS). Finally, an
alternative way is to receive TV signals via the open Internet
which is usually referred to as an Internet TV.
10. DTV QUALITY
• Standard Definition TV (SDTV) - SDTV is the basic level of
quality display and resolution for both analog and digital.
Transmission of SDTV may be in either the traditional (4:3) or
widescreen (16:9) format.
11. DTV QUALITY
• Enhanced Definition TV (EDTV) - EDTV is a step up from
Analog Television. EDTV comes in 480p widescreen (16:9) or
traditional (4:3) format and provides better picture quality
than SDTV, but not as high as HDTV.
12. DTV QUALITY
• High Definition TV (HDTV) - HDTV in widescreen format
(16:9) provides the highest resolution and picture quality of all
digital broadcast formats. Combined with digitally enhanced
sound technology, HDTV sets new standards for sound and
picture quality in television. Remember that HDTV and digital
TV are not the same thing. HDTV is one format of digital TV.
13. ADVANTAGES OF DIGITAL
TELEVISION
• Digital channels take up less bandwidth space
• Digital
broadcasters can provide more digital channels in the
same space
• Provide High-Definition digital service
• Provide other non-television services such as pay-multimedia
services or interactive services
14. ADVANTAGES OF DIGITAL
TELEVISION
• Permits
special services such as multicasting (more than one
program on the same channel) and electronic program guides.
• Digital television often has a superior image, improved audio
quality, and better reception than analog.
15. DISADVANTAGES OF DTV
• Digital television picture technology is still in its early stages
• Images have some picture defects that are not present on
analog television or motion picture cinema
• Some digital image sequences may have distortion or
degradation such as incorrect color, blurred image or haze
• Image and voice synchronisation issues
16. WHAT ARE EBOOKS?
• An eBook is an electronic version of a traditional print book
that can be read by using a personal computer or by using an
eBook reader.
• Users can purchase an eBook on CD, but the most popular
method of getting an eBook is to purchase a downloadable

(such as Barnes and Noble) to be read from the user's
computer or reading device. Generally, an eBook can be
downloaded in five minutes or less.
17. EBOOK READERS

computer, such as Microsoft's free Reader application, or a
book-sized computer that is used solely as a reading device,
such as Nuvomedia's Rocket eBook.
• AneBook reader hand-held device weighs from about
twenty-two ounces to three or four pounds and can store
from four thousand to over half a million pages of text and
graphics. A popular feature is its back-lit screen (which makes
reading in the dark possible).
