1.1                             BACKGROUND OF THE STUDY

At the beginning of the computer era, users logged on to one centralized mainframe computer that had all the processing power, using simple terminals. Over the years there was a shift to a more decentralized computing model with powerful personal desktops. In the same period the Internet infrastructure was deployed, resulting in a highly interconnected worldwide network of servers and multimedia desktops. This evolution gave rise to a host of new problems. Viruses, Trojan horses and worms pose a daily threat to vulnerable users in their home environment. Regular software and hardware updates make up a significant part of the IT budget of both professional and home users.

Thin client computing can offer a solution for these problems. In this paradigm, all applications are executed on central servers. The client device sends events (keystrokes, mouse movements, etc.) to the server, which processes the commands, renders the appropriate graphical output and sends the images back to the client. The client only needs to decode the graphical data. This results in lighter devices, since all calculation logic can be stripped from the device. Furthermore, the cost of end-devices will decrease, which is in the interest of both private and professional users. Especially for the latter, every reduction in hardware costs, even  a minor one, is a significant gain. The maintenance cost can also be reduced since managing and securing one central server farm is much simpler.

The United States National Institute of Standards and Technology (NIST) defines cloud computing as: a model for enabling ubiquitous, convenient and on-demand network access to a shared pool of configurable computing resources (e.g. networks, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction [Mell, P. and Grance, T, 2011]. The essence of cloud computing is resource integration; for education, this means the integration and management of numerous, complicated educational and data resources, and their intensive use in serving the cloud users.

1.2                                       PROBLEM STATEMENT

Recently, the massive growth of mobile devices has led to a significant change in the users’ computer and internet usage, along with the dramatic development of mobile services, or mobile computing. Smart mobile devices such as smartphone and smart pad have rapidly pervaded our everyday life, however these devices are limited by either their capacities (CPU, memory or battery) or their network resources, meanwhile, because of their relatively high prices and small display screen, these devices are also inconvenient to be deployed in large areas such as community, offices and factories. Besides, existing cloud computing technique for this kind of service is very poor to meet the attractive quality. Therefore, developing a thin client which is energy efficient and robust is very practical. Also, the developed thin client should adaptively match with the cloud computing center and provide the services and information fast, conveniently and accurately. How to get the resource and storage according to the demand is a critical and realistic problem.

Faced with these problems, this paper proposes an intelligent community information system, which is based on the architecture of thin clients, wide band network and cloud multimedia servers, aiming at the direction of new information technologies represented by cloud computing, intelligent terminals, embedded system and etc. Furthermore, this paper sets up the model of user requirements and the model of integrating software and hardware in cloud computing centers.

1.3                                          AIM OF THE STUDY

The main aim of this work is to present how a cloud can perform distributed multimedia processing and storage and provide quality of service (QoS) provisioning for multimedia services.

1.4                                        SCOPE OF THE STUDY

This work presents the principal concepts of multimedia cloud computing and presents a novel framework. We address multimedia cloud computing from multimedia-aware cloud (media cloud) and cloud-aware multimedia (cloud media) perspectives. First, we present a multimedia-aware cloud, which addresses how a cloud can perform distributed multimedia processing and storage and provide quality of service (QoS) provisioning for multimedia services.

1.5                      ADVANTAGES CLOUD MEDIA TECHNOLOGY

Cloud media technology offers number of key benefits to its service providers as well as the users through increased implementation time, efficient data storage capacity, less computation and cost. It created a striking impact in the multimedia content processing like editing, storing, encrypting and decrypting, gaming, streaming, compressing etc. Some more advantages are described below

Cost

Cloud media computing offers cost effective services to its service providers through efficient multiplexing of media contents like audio, video, image by providing a common infrastructure, utilizing the server, optimization, virtualization, Mobility and automatic processing. There is no need for physically acquiring a infrastructure or resource in our local system and thus reduces the cost.

Upgradable

Cloud media is an always connected to the cloud service provider and therefore it is upgraded and maintained without any manual interference. Software and security will be up to date always.

Compatibility

Cloud media allows the media content to be accessed anywhere through any smart device and it is compatible with all kinds of client service enabled computers, smartphones, cars tablets etc.

Consistent

Cloud media provides consistency in distributing the specific media contents to the users of other cloud within a cloud community using the streaming protocols like TCP/IP, UDP, RTP etc.

Green Technology

Cloud media computation uses optimized data centers for processing, distributing or sharing the media content to the users. But the traditional computation requires more energy consumption.

Ubiquitous

Cloud media offers the users to purchase a media content once and it can be accessed anywhere in multiscreen by providing customization ability depending upon the accessing device.

Storage

Cloud media technology has many bases for storing the media content in the cloud using the resources. Also it is more secure since the stored media content will be duplicated without manual interference.

1.6                       CHALLENGES CLOUD MEDIA TECHNOLOGY

More confusion

There are more confusion among the user in choosing the type of cloud since both pay per use and free clouds are launched by some mobile companies, service providers etc. So the users face difficulty in taking a decision.

Inside attacks

There is a possibility for phishing and stealing of media content by the employee of the service provider itself.

Legal and piracy difficulties

Since the cloud media computation is very new, the legal standards are not very good. There are more legal difficulties in the case of storing media content in the cloud outside the boundary i.e. servers which are outside the country. Also there are restrictions in getting the media content rights for different platforms and sharing the media content outside the range or limit.

Migration

Since more and more clouds are launched by the service providers, the user might think to move all his media content to some other cloud based on his change in requirements. But now the user does not have the freedom of doing that.

Challenges over standards

Currently many vendors (person who sells services) developing and launching their own private cloud environments based on their own conditions and security features which leads to issues in interoperability in the near future.

QOS

In cloud media computing, since it is a new area, the developers are concentrating more on computation speed and storage issue. Users going for unreliable networks without their knowledge to share the media content even though there are availability of more promising streaming technology and increased broadband speed.

1.7                                                   LIMITATION OF THE STUDY

As we all know that no human effort to achieve a set of goals goes without difficulties, certain constraints were encountered in the course of carrying out this project and they are as follows:-

1. Difficulty in information collection: I found it too difficult in laying hands of useful information regarding this work and this course me to visit different libraries and internet for solution.
2. Financial Constraint: Insufficient fund tends to impede the efficiency of the researcher in sourcing for the relevant materials, literature or information and in the process of data collection (internet).

• Time Constraint: The researcher will simultaneously engage in this study with other academic work. This consequently will cut down on the time devoted for the research work.
