File Formats are the original way information is
encoded of the storage of a file on your
computer. File Formats are created to hold
different forms of data. File Formats include
different aspects of multimedia such as audio
and video. Different types of Audio file formats
are MP3 and MP4. The advantages of using
MP3 File Formats are The MP3 files have been
compressed to the file size smaller which allows
the user to rip a huge amount of music and audio
file on a disk. A Disadvantage of Using MP3 file
formats are they often have low audio quality.
However an advantage of using MP4 is it has the
same file extensions the MP3 files. However a
disadvantage of MP4 is the files are difficult to
edit. These Audio file will allow used the add
sound and dialogue two the adverts we will be
creating for advertising a new brand of energy
drink.
The one the main types ofVideo file isMPEG4.
The Advantage of MPEG4 are its files have a
very good quality standard with lower file
formats. A Disadvantage of MPEG4 file might
not run on every DVD ROM player because it
isn’t supported by Microsoft and because of all
the file variations. The files Video files also allow
the user to edits and created videos. This will
help use created the video for our advert on a

2. Technology
Compression
Compression is where information is encoded
reducing the file size of the file making it
quicker to be sent. One of the main file
compressing softwares is called WINSIP.
WINSIP also you to compress files and sent
them on.
Compression can be either Lossy or Lossless.
Lossy data compression is where a file losaes
data that can’t be restored and the quality of
the file can be lost. For example a
lossyimages becomes pixelated and unclear
the user. Lossy images also have variations in
colour and pixels which are arranged in
columns and rows of squares, that are all the
same size.
However Lossless compression is where the
file doesn’t loss its quality and data can be
restored. Lossless images aren’t pixelated and
are often very good quality.
File compression will also help us create our
adverts to advertise a new brand of energy
when we have to send reports to the client of
the production company of our progress in
producing these adverts.

3. Streaming methods
Downloading
When you downloads and file the whole
file is saved on to your computer which
you can open and view anytime without
having to download the file again. An
advantage of downloading are it is quicker
to access to different parts of the file.
However a disadvantage of downloading is
you have to wait until the whole file has
downloaded before any of the file can be
viewed. Downloading will be one of the
key element when producing our adverts of
a new brand of fizzy drink which will
allow us to have permanent access to the
video file we are going to produce in the
next assignment. Windows downloads the
files automatically.How HTTP software
can download file to and from a website.
This is an example of a downloading
software which allows you to download a
file to and from a website.

This is an example of a video
streaming site that is Youtube
Streaming
Streaming allows the user the start
watching the file almost as soon as the
file begins downloading. You tube is one
of the most popular video streaming sites.
The advantages of video streaming are it
doesn’t involve any waiting and is able to
broadcast live events. However and
disadvantage of streaming is sometimes it
takes a while to buffer. Streaming will
become a key element in publishing and
advertising the new brand of fizzy drink.
Streaming is also used as a marketing by
advertising and promoting new products,
items or the latest films.

4. Streaming Methods
Progressive Downloading
Progressive downloading is known as a Hybrid method of streaming. In this Progressive video
clips downloading but doesn’t start playing until a portion of the file has been received. The
advantages of progressive downloading are it provides and quicker playback time than it
would to download and play and when the file arrives, it also allows the user to fast forward
and rewind the content of the file. However and disadvantage of Progressive downloading is
not all media players can support the file once the file is in a progressive download file format.
Windows Media Player is an example of
progressive downloading software.
