INTRODUCTION
In business organization data handling is very serious matter which managers have to
maintain. If it is about the data management the system have more space but when it comes
about the media a single file can take space of 1000 files (Das, 2017). There are various format
available for the media that are used by the business people however, the main among them is
streaming media. Streaming media can be considered as the multimedia which is being received
by the end users during the process of its delivery to the provider. The end user can use the
media player for playing the specific file. It can be digital movies or a song as well. The live
streaming refers to the the content of the internet being delivered in real time. The real time is
considered as within a few nano seconds. The live internet streaming needs a source of media. It
can be either a audio device or the video camera. There are various challenges as well that are
being faced in the streaming of the audio or video outputs.
TASK 1
Difference between .wav and MP3 compressed format
Key difference: Wav file have different size and quality and also first entirely uncompressed file
of digital format. However, MP3 files having larger space are audio compressed and are about
1/10 of its original size (Holt and et. al., 2017). Here uncompressed means having exact format
as that of original file, having same quality but differ in the storage capacity.
Wav files are considered as uncompressed and are actually used in some specific formats
such as in the broadcasting of the CD files. It stands for Waveform Audio File Format. They
support music CD files which are of good quality. They are universal in format and comprise of
high spaces. As these files can easily moulded and edited and thus, changes by user should not
be saved in these files. Due to this reason it is more and another important reason it is highly
preferred, preferably for professionals they use it for its higher quality. These are termed as the
best choices for processing loops that are being done with the flash for various animations
around the web. These are considered in the animations option better than they can be associated
with some other form. Though it is not an popular format as it takes more time as transferring
file, then also due to its quality and simplicity it is preferred.
Mp3 is considered as a codec and stands for MPEG-1 Audio Layer III. It can be loaded
rapidly and have very good sound quality. When files are being saved in this format, these are
produced very small in size if being compared with the wav pattern. However, it has been patent

by digital audio. An algorithm which is especially made to lower the amount of data which is
required for recording audio while still sounding is like a firm recollection of the primary
uncompressed audio. However, there is disadvantage of using this format is that there can be
some quality issues regarding the sound of the music and all the audio output. The benefit of
using a MP3 format is that these are smaller in size as compared with the wav formats. Wav. is
that format that is being used for the uncompressed audio files and MP3 is considered for using
the files after compression. The sound quality is better in the wav formats as compared with the
mp3 formats (Kumar, Kumar, Divakar and Gokul,2017). Both the formats have their own
advantages and disadvantages. The music can be download from both .wav and MP3
format. .wav files are used to download files form Television, wireless, DVD or any other media
that need high level of uncompressed sound quality. For loops the these files are correct choice
in order to process it with flash for web animation. For web pages ,web videos,one can use MP3
files .The MP3 format can also be used to download anything from internet. With a very good
sound quality MP3 loads rapidly and plays. The 128 kbps is recommended for internet usage.

The key differences between them are listed below:
Factors WAV MP3
Explanation
It requires a very high level of audio quality file
which is used for applications like TV, radio,
CDs or any other media.
WAV format is considered as lossless audio
format which provides a better quality than the
MP3 format.
It is a patented encoding
format that is high used for
digital audio and is highly
popular due to low storage.
MP3 format is considered as
LOSSY compression which
has the smaller size of file and
because of which, it has lower
quality of sound as well.
Stands for Waveform Audio File Format(Watson and et. al.,
2017) MPEG-1 III Level Audio
Extension .wav .mp3
Formatting
It is considered as a subset of RIFF format
which makes it capable of storing various
multimedia files. It is Uncompressed
The compression system
minimizes the number of bytes
in the audio and this format is
considered as Compressed
Formed Microsoft and IBM Moving Pictures Experts
Groups
Audio quality HIGHER LESS
There is loop in the .wav format but not in mp3 format. These are small audio file
generally of 10-30 seconds. Its beginning and end are properly edited so that it can played
seamlessly without a pause.

Drawbacks of .wav file:
They are larger in size up to an average of 30 MB for normal file and standard can have up to
500mb. For portable devices this files cannot be completed (Yevmenkin, Newton and Fullagar,
2017).
The size of WAV file increases because it is having a header and its contents part. All
the information related to the size, time, frequency, occurrence, etc. of the file is stored in the
header. It should be recognised that the place where the actual data is found is also the header.
The format of the WAV is in the format of container, so the data can be stored in various
formats.(Yi and et. al., 2017). It should be noted that the Uncompressed PCM format is one of
the, it can also be stored in ADPCM, MP3 and other formats. In case if there is an audio codec of
the format is available then can be read and written. The data contained within the WAV file is
the major difference between compressed and uncompressed WAV files. Before playing it back,
uncompressed raw audio samples or compressed raw samples must be decompressed.
TASK 2
Type of solutions based in three DLNA architectures.
Protection of media while sharing them has always being great concern for the
organisation. This become more severe when the media is transferred with consumers. In this
case, a high demand of piracy free data raises. In order to deal with these issues, the
pharmaceutical entity can take assistance from DLNA. A powerful trade group (Digital living
network alliance) that was founded by Sony in 2003 that is helpful for various organisation
running in different sectors. It develops and promotes a set of interoperability plan for sharing
digital media in multimedia devices (Peng and Zhuang, 2016). In addition to this, the tool
comprises high protection ability by using cables, satellites and telecom service providers for
protection of the link on both ends i.e. sender and receiver. Also,there is a extra level of security
provided by the digital rights management. This can be abbreviated as DRM, it allows
consumers to share their content with the organisation without any danger of piracy. The chosen
pharmaceutical company can rely on DLNA to promote its products using podcasts on its
website. The goal of DLNA is to establish an ecosystem of compatible products fro networked
media devices.

There are basically three versions of this tool. Version 1.0 guidelines was published in
2005 and at present there are over 2000 certified devices. Secondly, expanded guidelines of
version 1.5 guidelines published in 2006. In this additional cert options available in Q3. Also,
there exist one more version V2.0 also known as additional expanded guidelines. The role of
DLNA is to separate multimedia devices into 10 different certified classes. These classes are
further segregated into three categories which are Home Network Devices, Mobile handheld
Device and home infrastructure Devices (Yang, and et. al., 2017). The home network devices
covers PCs, TVs, AV receivers, etc. In context to mobile handled devices they are smartphones,
tablets, digital cameras, etc. Further, home infrastructure devices covers devices such as routers
and hubs.
There are basically three models of DLNA, two box models and three box models. There
are further two type of two box models namely 2-box pull and 2-box push. In two-box pull
model, initially the media info is taken from the library. From this information, the relevant
content is selected followed by content streaming. On the other hand, in two-box push model
initially the media library info is taken and content is selected. Later, URI is passed for the
selected content (Yang, 2016). Further, the content in binary system is taken. In contrary to this,
in DLNA 3-box model there are four steps of getting content. Firstly, Media Library Info is taken
out of which the content is selected. Later, URI and metadata is passed for the selected content in
the device. Further, the user gets content binary stream.
Network attached storage (NAS) is an ideal solution for streaming and archiving of
pictures, music and videos. 1-Bay NAS uses two-way push method for streaming of media. For
it's set up a network attached storage is required for installing the hard drives. Later, storage
space is managed followed by creating media structure (Peng, and Zhuang, 2016). Lastly, it is
configured with the media centre. It's hardware specifications are as follows:
 Processor : Dual Core - CNS3420, CPU - 700MHz
 HDD boots
 Lock: Kensington
 RAM: DRAM of 256MB
 (1) Channel One: Serial ATA II
 port: (1) Ethernet
 ports: (2) USB 3.0

On the other hand, a 2-box pull type DLNA model universal media server is also a great
media streaming that can be used by selected pharmaceutical company. This media streaming
tool can be set up in different devices. As UMS is Java application hence, it is highly essential to
have this installed (Diao, and et. al., 2017, June). Later, by downloading UMS on Windows it
can be installed. For complete set-up the step involves: Installation of JAVA 7 JRE on the server.
It's specifications are as follows:
 Processor: Intel Core 2 Duo, 2.4 GHz or better
 A faster CPU is required for transcoding multiple devices
 2GB RAM minimum
 Vista Windows
 OS X: Snow Leopard 10.6.3
 Debian, CentOS or SuSE Linux Ubuntu, Fedora,
 Media metadata and software updates: An ADSL/Cable/WiFi Internet connection
 Uncongested networks: strong signal 802.11n/ac wireless network
 Bugged gigabit web
There exist one more device that can be used by selected firm. This tool is PlayOn, a
three box model of media streaming. Despite of some higher hardware requirements, this media
streaming method is best indeed. The set up method of this media streaming source is simplest of
all the above mentioned tools. In this, the PlayOn is first downloaded in Windows devices later
by installing it, user can use it. Specifications required are as follows:
•Windows 10, Windows 8/8.1, Windows 7 of Microsoft
• At least Windows Internet Explorer 9
Latest version of Internet Explorer available for OS.
• RAM: 512 MB (1 GB recommended).
• Network connection
Out of all these the most suitable streaming media device for the selected organisation is
PlayOn. Further, it focuses on stability and compatibility. It also allow easy integration of online
media. Also,its set up and using method is comparatively easy than that of the other two. In
addition to this, this tool support local and online content (Peng, and Zhuang, 2016). However,
7

it should be recognised that it is available only on Windows. This streaming media is easy to
install and use. It can be set up in devices by simply downloading and installing PlayOn on
Windows PC followed by launching it. It's simple set up steps also plays major role for covering
maximum users.
CONCLUSION
From the present report, it can be concluded that media streaming plays a major role in
the digital operations involving any type of media. In this report, various issues that are faced in
streaming are analysed so that effective devices can be recommended. Further, the use of DLNA
in promoting and developing and promoting a set of interoperability plan for sharing digital
media in multimedia devices is explained. Moreover, different streaming media devices from
antithetic DLNA architecture is suggested for the organisation.
