Computer Networks And Internet Protocol Television Essay

The advent of figurer has changed the course the ground moves. Distance factor is no persistenter a problem. The physical might appear a big put in with matters at furthermost off places provided when the world in virtual(prenominal) trunk doesnt believe in distance. E trulything ass be achieved in spite of appearance proceeding if not seconds. The whole engine room behind this mega change is base on ready reck sensationr and is termed as In cropation Technology. This technology has led to the creation of a cyber world or electronic all(prenominal)y generated world with the inspection and repair of computers connected to from each one other by means of suitable wires. without delay words care cybercafe, cyber chat, cyberspace, cyber shopping, and so forth wear started making rounds. People can s send a steering electronic mails to far off places within seconds. Details and tellation argon acquire transferred within few seconds. People in Shanghai and New York arg on just seconds a substance. Transferring selective information in electronic form is rattling the fastest way to transfer things. Its not only the message transfer that has been revolutionized but withal the line of work world. There are virtual shopping malls with website offer you a range of crops ranging from computer peripherals to groceries.Companies are now providing details of their crossway through their website and are accepting customers requests of information and now even orders for products are world accepted. E precise(prenominal)thing is available. Money transfer can easily be through through wire transfer techniques. People do not wait. This world is not ruled by armed soldiers or any thermonuclear weapon. Its the information which rules. The physical world just has to react on the outcome. Its role is just for receiving and sending.This high performing virtual world has gather in significant change in the performance of the actual world (Tanenbaum, 2003) . Things in real world are now easier to comprehend. Outsourcing has helped in accessing low speak to labor in far off Asian nations like India and China. multinational companies like Microsoft, IBM, GM. , GE etc. have chest of drawerss in almost in each part of the world with performance of each of these units can be monitored from any of its offices. Their offices have been networked though LANs i. e. , Local Area entanglement and WANs i.e. , tolerant Area Network. They have virtually made themselves available to their customers any epoch anywhere and just a click away (Tanenbaum, 2003). 2. Computer dust & Network of computers A computer arrangement and network of computers are actually two diametrical but interrelated things. A computer system is just a normal computer including peripherals and software necessary for the procedure of the device (Webopedia). But if we talk of Computer Network, it can be specify in a very simple way as a network of computers (Princeton). But giving full importance to all factors getting into act when we talk about network, the definition which actually makes complete find is none other than the two or more computers connected unitedly to share hardware, software and data and has been implemented according to some network network topology (Tanenbaum, 2003). The network can have all peripherals located within an office or building. This arrangement is often termed as Local Area Network or LAN (Tech, 2006). If the same is achieved in a wide land i. e., computers connected to the network are located at places as diverse as countries in different continents, we can call the same as Wide Area Network or WAN (Cisco, 2006). Calling all computers and other intelligent parts of it as nodes, the term network topology can be defined as patterns of links connecting a couple on of nodes of a network. 3. profits Protocol & IPTV Technology related tv work which include uplink and transmission has seen some of very revolu tionary inventions of modern science.The television delivery system has now moved from terrestrial transmission through analog signals to encrypted digital signals through internet as well as IPTV (Anderson, 2006). The recreation world through television is now very a good deal eager to move from TV being delivered through wire to Internet Protocol Television with content being viewed through technologies utilize for computer net whole caboodle (Lu, 2006). The last decade of the 20th century witnessed the massive growth in Internet Protocol found work.Now with the fast development of hardware and software technologies, this internet world has now developed to accommodate serve like VoIP and umpteen other telecom products (Wikipedia, 2007). It is a system which delivers digital television services to registered endorsers in a managed network with address based technology. The unique IP address of a subscriber provides him a virtual address over a network and creates a connec tion surrounded by the service provider and the television (Wikipedia, 2007). 4. Television through IPTV a vernal experience IPTV is going to give the most electrifying experience to its subscribers.Its not just seamless TV viewing but also more interactive and personalized. Things like participation in a post show or any discussion board leave alone only require the use of the remote term sitting on the couch. Now the user entrust not feel being bombarded with a long list of conduct rather get a very originative option to receive them with a much richer experience (International Engineering Consortium, 2007). The nonpartisan signal encompassingcasting system through the network over which IPTV depends, allows the viewing audience to make selection that too on demand with time shift key option.The additional services which can also be incorporated with IPTV are the Web Browsing i. e. surfing the internet, gaming with a game solace with the current system and finally th e communication applications which can enable email, MMS, Chat, etc (Telecom Italia, 2006). skeletal frame 1 (IPTV delivery Infrastructure) The Set-Top Box which has made this IPTV happen which at one end is connected to the TV set while the other end to an ADSL connection can easily be made to supply open TV services (BTV) as well as Video On Demand (VOD) services.This BTV facilitates the simultaneous reception by the users of a traditional TV carry on. And using multicasting protocols IPTV can make available services which are resembling to experiences of a traditional TV like Free-to-air or Pay TV or a Pay-Per-view service (Luarel Networks). The same IPTV can be used by service providers to provide the VOD service which is made available on request. The VOD service requires implementation through IP unicast protocols (Ericsson, 2006). The enhanced IPTV can also make Personal Video Recorder (PVR) services available.The local PVR makes way for video-recording on the STB hard-di sk with another set of functions for live, pause and replay. Similarly the Network-based PVR stores the data on the operators server which is generally used for VOD (International Engineering Consortium, 2007). On technological point, the IPTV makes way for better utilization of available infrastructure like the bandwidth. Traditional transmission technology actually sends more than hundred business lines simultaneously while the IPTV requires just one channel to be displace to the subscriber at a time.Every time the user selects a channel or a program, a rising streaming takes place with data related to the newly selected channel (Anderson, 2006). 5. IPTV More Advantages, More services & More Business The IPTV will lead to a very new level of interactivity among Internet and data mainly as voice and video. A cable based TV network beams data in form of video mostly in MPEG format through an explicit bandwidth element while the internet which enables high speed data transfer wor ks on an IP based network and the data transfer is based on packets rather than streams.Both the technologies are technically very different. This IPTV is an dental amalgam of both the successful technologies. Being a data-centric application, the packets over this network can deliver both video as well as data (International Engineering Consortium, 2007). Figure 2 Telecommunications IPTV system solution The traditional cable network is often overloaded with more than 100 channels being transmitted simultaneously. So there is a limitation of maximum minute of channels that can be made available to the subscriber.IPTV has a very clear advantage (Times News Network, 2006). Theoretically this technology can make almost infinite number of channels at the customers disposal. The transmission line actually transmitted a single channel which has been demanded by the customer. So the infrastructure usage per customer is negligible while opening a new era of almost every channel on the plan et being made available to the user. The IP technology being a packet based product requires an acknowledgement to be sent to the source for every packet.This ensures that every packet sent by the source should remain intact and any loss of data will require resending of the same packet. This feature ensures very high quality of the product which the subscriber will receive (Anderson, 2006). The advantages associated to IPTV is not just conventional entertainment and advertisement based business but the technology can have its usage in developing new products which can make way to many other forms of businesses. The web based training is one of the many other possibilities.The IPTV network can be used to run different courses by making the videos of the classes available to the registered students (International Engineering Consortium, 2007). IPTV is the coterminous big thing after telecom and internet. The business possibilities associated with this technology is almost as broad a s the human thought. Almost all telecom companies are lay big money in exploration and marketing of this product (Blau, 2005). The business network and the corporate LANs may be sterling(prenominal) beneficiary with the delivery of videos and television content.The customized content delivery and the extremely desex network will reduce the theft cases to negligible. Customization facility will help the advertisers to understand the behavior of consumers and then will go for personalized ads that will translate into significant business returns (Iyer, 2005). 6. Conclusion The IPTV is going to be the next big thing in communication and media industry. With money pouring inform all big telecom companies IPTV is going to be a very serious business with entertainment becoming more and more customizable.The subscriber will experience a very different medium of entertainment with highest level of interactivity and almost innumerable possible services that too very much on his own wishes . 7.Bibliography Anderson, N.
