MEDIA PLAYER SKIT


MAK

MAK/SKIT Page 10

The product will enable interaction with gaming consoles, such as PlayStation 3 and Xbox

360 via wireless network connection and USB cable connection in order to support music

distribution between these devices.

2.3.2 MOBILE DEVICES:-

The external hardware interface will support mobile devices, such as smart phones and digital

music players, via a Universal Serial Bus (USB) cable or Bluetooth connection in order to

allow the exchange of music files and synchronization of playlists.

2.3.3 EXTERNAL STORAGES

2.5 PRODUCT FUNCTION:


11/26

MEDIA PLAYER SKIT


MAK

MAK/SKIT Page 11

2.5.1 FUNCTIONAL REQUIREMENTS (OR PRIMARY FUNCTIONS)

The system shall have an Internet connection. This will enable the downloading of songs

from a digital media store. In addition, users shall be able to use a web browser in locating

songs to download. The system shall allow a media server configuration. This will allow

music in the library to be shared with compatible remote devices. Therefore, both the system

and devices shall use a common networking protocol. In this user could access music located

on their media player through a games console. As a result of this, the system shall restrict

access to the shared network to those who have authorized access. The system shall

communicate with distribution devices via a connection. This could be a wired connection or

optionally a wireless connection.

2.5.2 NONFUNCTIONAL REQUIREMENTS (OR SECONDARY

FUNCTIONS):

2.5.2.1 Performance Requirements

The application must have a minimum processor speed so that there are some restrictions on

what type of computer can use it. However this will be as small as possible to enable a broad

range of clients to use the application. From Jonathons ethnographic study we can see that

speed was a common issue while distributing music. The system must also aim to use

minimum hard disk space yet keep the quality of the media as high as possible.

2.5.2.2 Safety Requirements

All songs downloaded will be checked before downloaded by the system to make sure the

music has no viruses in order to keep the users computer safe from being attacked. The next

requirement is that a compressed version of the songs which are downloaded get saved to a

back-up area so that if something goes wrong with the software like it crashes the song files

are still safe.

2.5.2.3 Security Requirements


12/26

MEDIA PLAYER SKIT


MAK

MAK/SKIT Page 12

Information of users such as IP addresses will be kept private so that third parties cannot gain

access to this personal information in order to keep within the Data Protection Act. The next

requirement is that the system should prevent the user downloading material which would be

deemed offensive such as blasphemy and obscene material and also the system will check

certain age restrictions on songs to make sure that material isnt seen by minors. The final

limitation is that the method of which people share their music should have limitations so that

Copyright of songs is not broken.

2.5.2.4 Software Quality Attributes

These are a variety of constraints that might affect the user or system. The system should beable to by-pass security systems which are on the computer which deny our system

connection. This is to enable that reliability is always at a high level; some ethnographic

studies showed that users could not connected to the internet due to firewalls. The next

requirement is that the application should enable music files to be converted to different,

valid, formats and that all common music formats should be supported; any which arent are

provided with plug-ins to enable them. This is to ensure interoperability between the files and

system, the decision for this was that in numerous ethnographic studies the downloaded

music couldnt be played using their chosen device.

Another interoperability requirement is that the system should allow any storage device to

connect to the system and enable the distribution of music. The reason for this is that researchshows people used ITunes but they could only distribute the music on to their IPods which

was found to be a problem. A usability requirement is that there should be a help guide within

the new system so that the time that new users can soon understand the system; however the

system will be simple and therefore self-explanatory.

There will be hotkeys throughout the system so that users can speed up their performance

once they have mastered how to use the program. The system should remember the last song

played on the system so that users can manipulate the program easily and efficiently.

The system will have a predictive search where the user starts typing in the name of a song

and the system brings up a variety of options which begin with the same parts as the search.

The reason for this is that if the user sees there search in the drop down box it saves themtyping it out which may cause typing errors.

2.6 USER CHARACTERSTICS:

The application is intended for users who use and distribute music electronically. One of the

highest priorities is age verification; people under the age of 16 should not be allowed to

purchase the songs online and adults may also chose to lock specific songs which contain

offensive material. The application shall allow both novice users and more competent

computer users to use the system effectively. For more frequent computer users, there will be

options for advanced functions to allow them to generate their own playlists along with

storing and loading multiple files. The system shall restrict remote users being able to

download music on a clients system.

The target clients for our software are ordinary computer users who distribute music media. It

is assumed that the target group does not have to be familiar with the use of any software of

similar functionality, but to have a basic computer and Internet skills that will enable them to

use this software.
