Digital video can be stored and distributed digitally, allowing for perfect copies without quality degradation. However, this also makes digital video easier to illegally download and share online. While 3D films provided an immersive experience, many viewers found the 3D glasses uncomfortable and some experienced health issues from viewing 3D content. This led many consumers and manufacturers to lose interest in 3D television. On-demand and internet streaming services allow viewers to watch television programming at their convenience on multiple devices.

2. DIGITAL VIDEO
Digital video is a representation of moving visual images in the form of
encoded digital data. Digital video encompasess a series of digital
images displayed in rapid succession.
Digital video can be copied with no degradation in quality, and the
footage has high clarity in comparison to Analog videos for example.
Digital formats include
.MPEG4
.SWF
.WMV
.MOV
...and more.

3. DIGITAL VIDEO
Digital video can be stored in Blu-ray Disks, or downloaded onto
one’s computer storage, and can also be streamed online, which may
causes problems as it is therefore easier to encrypt and steal and
let loose online for people to access for free, meaning the creators
may not earn the money they should be earning.
Digital video is very different to Analog video, which came first.
Digital video displays a stream of digital images very quickly,
whereas analog videos use the technique of projected photographs in
a rapid sequence instead.
Digital video also has the advantage of being able to be copied
without any degradation of video quality, unlike analog videos which
do experience a degree of quality loss when copied.

5. 3D
A three-dimensional film, or 3D as it’s commonly known, enhances
visual presentation through a depth perception, in addition to
height and width shown through regular, 2D footage.
2D-plus-depth and multi-view display are examples of techniques
used to create the form of visual 3D footage.
3D films have existed since 1915 and were particularly popular
to feature in American cinema during the 1950s, and later had a
worldwide revival in the 1980s and 1990s through IMAX theaters
and re-appeared again during the 2000s, especially in 2009 and
2010, during the featuring of the film Avatar, the 24th most
successful cinema release of all time.
3D is available in television and Blu-ray too.

7. As you can see from the previous slide, statistics show that
3D films are not as popular to watch as the regular 2D
screening. This may be due to a number of reasons...
Firstly, people do not want to be burdened with the hassle of
the big glasses, needed for watching 3D films, television or
video games. The fact that one has to wear flimsy, plastic
glasses, is very annoying, particularly for those who have to
struggle with putting them on over their daily pair.

8. In addition, Sony ‘active’ glasses will not work when
watching a 3D film on a Panasonic TV — and vice versa —
meaning one’s 3D glasses can only be used with a television
made by the same manufacturer, which is also frustrating.
Another issue is that many viewers were prone to eye strain,
headaches and even migraines, through the watching of 3D
television, a result caused by the fact that the brain finds
simulated three-dimensional images confusing.

9. In a test carried out at Eindhoven University in Holland,
researchers asked 39 people to read some text on a 3D screen placed
10ft away. 7 of them started to feel sickness, eye strain and double
vision. Fears that 3D TV can damage developing eye muscles therefore
have caused many eye experts to caution against children below the
age of eight from wearing 3D glasses.
The more issues found, the less enhancing the experience will be,
and so the concept of 3D media became less impressive and used so
little, to the extent that companies such as LG and Samsung have
stopped producing TVs with the 3D feature.

10. Another statistic...

11. The Internet
The internet is useful as it can be used as a promotion tool for
various media companies, information spreading via websites and
social media such as Facebook and Twitter, and can also be
helpful in sales, as people are able to purchase products of the
media industry a lot easier, sitting in the comfort of their
homes or on the go, rather than spending a day out in the shops.
They are able to do so through channels such as Amazon Prime and
online streaming sites such as Netflix.
The internet can also be used through televisions and on mobile
devices, so this method of attaining media related information
or products is widely accessible and easy to reach.

12. High Definition
Television
High definition television or HDTV is a television system
which provides a higher resolution than that of the
standard-definition television, HDTV is currently the
standard video format used in broadcasting.
The term High definition was once used to describe many
television systems though these systems were only considered
high definition compared to earlier systems.
Earlier HDTV used analog technology to broadcast, though we
find that today it’s become common to transmit it digitally
because it uses video compression.
https://en.wikipedia.org/wiki/High-definition_television#History

13. High Definition vs Standard
Definition
High definition is sharper and much more
detailed picture than standard definition the
answer to why this is true lies in the amount of
pixels displayed or more commonly known as the
display resolution.
The display is listed as being width by Height,
the units are corresponding to the amount of
pixels in that frame. The greater the number of
pixels you find the better the image quality.if
you are editing footage it’s much better to have
it in Hd so as to not lose image quality when
zooming in or out.

part-1-sd-vs-hd/

14. High Definition & Digital Compression
The images on the side represent the
compression of pixels when they are or
aren’t compressed it shows us that if the
pixels are really visible then the
resolution must be low.
Broadcasters use MPEG-2 in order to
compress an image and transmit it, this
program allows you to allow the image to
suit the screen size and pixel count
through encoding.

15. ON-DEMAND
The advantage of this is that it allows viewers to shift the
television programming so it makes time for them to view it
later on. The content is typically but in no means limited to
current and past shows, movies or original programming. It’s
also available on multiple platforms.
On-demand has limited reach, advertisements on it reach a
little more than 1% of the viewers as they have the ability
to ‘skip’ the ad.

16. ON-DEMAND
On-demand refers to being allowed access to
a certain content without being forced to
wait for the daily broadcast they are doing
this via the internet an example would be
the BBC iplayer they do this recently after
the program has been transmitted, because
then you can choose when to watch the
videos the technical name for this is
actually “TV on demand”. Some of these on
demand services allow you to download it
onto your PC so that you can watch it with
and without internet.

17. Internet
The internet is a public service in which transmissions from
the streaming servers normally are sent to the consumers end
of the screen.
Online television is the digital distribution of television
content, such as TV shows (e.g the Shadowhunters series), via
the public Internet service through things like Netflix.
