3. Extended Internet Usage

Now as we have seen some basic uses of the internet. Let us discuss some more advanced uses. Even though there many additional uses of internet but we are going discuss about 4 main topics in this research paper.

  1. IPTV:

Internet protocol Television(IPTV) is an assembly in which Television services are distributed over an IP network in a digitized form. So we can say that it uses the existing broadband network to deliver us a TV service which is more reliable, efficient and data is 100% digital, thus improving the overall quality over an analogue TV

  1. VOIP:

Voice Over Internet Protocol(VOIP) is a system in which voice conversation can be conveyed over the IP network. The end user in a VOIP network has the authority to make telephone calls over the Broadband network. The Network used in such type of connections can be through the internet which makes it global or Intranet which makes it local the Inside Network of the company.

  1. Cloud Computing:

Cloud Computing is a process in which data is stored in a Large centralized server or data storage unit. Thus providing an online access to the stored data as per requirement of the end user. The data stored in the cloud not only is shared my multiple users at the same time but also can be reallocated as per demand of the end user. Thus reducing the storage, power and space of data by using the same data for multiple users.


Miracast is basically a HDMI based dongle which is used for live streaming of Video and Audio channel without using an Access point. So a device which uses a point to point network technology which allows different devices to connect to each other using Wi-fi direct thus allowing them to share live streamed data.

Now we will have an in-depth discussion of each and every topic separately discussing about their architecture, functioning, advantages & etc.


4.1 Introduction

IPTV is basically an internet based television service which uses networking and architecture methods of the IP system over a Packet switching network structure. IPTV has 3 main groups in which it can be classified

  1. Live Television

IPTV uses a set-top box which uses a broadband IP data network to access channels, subscription services and other multimedia services over and safe and end to end network.

IPTV services are sometimes bundled with internet access and VOIP services altogether over the same infrastructure. IPTV is not as simple as someone watching a video over the internet. IPTV connection to home provided by telecom companies uses optical fiber and digital subscriber lines (DSL) to set up a link towards a housing compound. For Cable operators they use a hybrid fiber co-axial (HFC) cable to provide a broadband connection to the subscriber.

IPTV incorporates the procurement, processing and safe delivery of all video content over an IP based Setup. The service provider uses various other service providers like satellite TV carriers, cable TV carriers, Telephone companies and private network operators to bundle up a single service which is provided to the end user.
