This technology is particularly convenient for business users in different cities or even different countries because it saves time, expense, and hassle associated with business travel. Uses for video conferencing include holding routine meetings, negotiating business deals, and interviewing job candidates.\r\nVideo conferencing's main advantage over teleconferencing is that users can see each other, which allows them to develop stronger relationships. When a video conference is held for informal purposes, it is called a video call or video chat.\r\nThere are a variety of ways video conferencing can be conducted. Individuals may use web cameras connected to our built into laptop, tablet, or desktop computers. Smartphones equipped with cameras may also be used to connect for video conferences. In such instances, a software-based platform typically is used to transmit communication over Internet protocols.\r\nSome businesses use dedicated video conferencing rooms that have been equipped with high-grade cameras and screens to ensure the conversation is clear and with limited technical faults. Third-party providers often install and assemble the hardware needed to conduct the video conference.\r\nCompanies with multiple offices might establish direct video communications between their locations in order to allow their teams to work more collaboratively.\r\nVideo conferencing can also be used as a medium for conducting training, with the instructor teaching a remote class from almost anywhere. This can be done in a corporate context, especially for getting workers the knowledge they need to better perform their jobs. The academic world can also make use of video conferencing to connect a traditional classroom setting with students who have based a considerable distance from the school.\r\nA video conference may also be used to conduct regular meetings with a company staff or to confer with shareholders about the latest activities at the business. It may be used to announce significant changes at a company, such as introducing a new CEO or to present information in an interactive way that allows all participants to engage in discussion about what they see on screen.\r\nHotels and conference centers sometimes make video conferencing services available to guests who require such services. This may be offered in suites or conference rooms that have been equipped for this purpose.","materialsDescription":" <span style=\"font-weight: bold; \">What is video conferencing?</span>\r\nVideo conferencing is two-way interactive communication delivered using telephone or Internet technologies that allows people at a different location to come together for a meeting. The video conference can be as simple as a conversation between two people in private offices (point-to-point) or involve several sites (multi-point) with more than one person in large rooms at different sites.\r\nA basic video conference setup has a camera and a microphone. Video from the camera and audio from the microphone is converted into a digital format and transmitted to a receiving location using a coding and decoding device, often referred to as a &quot;codec&quot;.\r\nAt that receiving location is another codec device that decodes the receiving digital stream into a form that can be seen and heard on monitors or televisions. At the same time, video and audio from cameras and microphones at the received location is sent back to the original location.\r\n<span style=\"font-weight: bold; \">What are the benefits of video conferencing?</span>\r\nVideo conferencing saves travel time and money. Participants can see and hear all other participants and communicate both verbally and visually, creating a face-to-face experience. PowerPoint and other on-screen graphics, as well as other cameras, are also available presentation options. People's downtime is reduced and productivity gains are achieved by removing the logistics of flight preparations, airport delays, hotel stays, and all the other inconveniences of business travel. In distance education, video conferencing provides quality access to students who could not travel to or could afford to relocate to a traditional campus. Video conferences can also be recorded and made available in a variety of ways, e.g., DVDs, streaming video. Besides distance education, other applications include meetings, dissertation and thesis defenses, telemedical procedures, and online conferences.\r\nPeople use video conferencing when:\r\n<ul><li>a live conversation is needed;</li><li>visual information is an important component of the conversation;</li><li>the parties of the conversation can't physically come to the same location;</li><li>the expense or time of travel is a consideration.</li></ul>\r\nExamples of how video conferencing can benefit people around campus:\r\n<ul><li>Guest lecturer invited into a class from another institution.</li><li>The researcher collaborates with colleagues at other institutions on a regular basis.</li><li>Thesis defense at another institution.</li><li>Administrators from different parts of campus need to collaborate on administrator issues such as a campus strategic plan.</li><li>Researcher needs to meet with a review committee about a grant.</li><li>Student interviews with an employer in another city.</li></ul>\r\n<span style=\"font-weight: bold; \">Please explain the etiquette for video conferencing</span>\r\n<ul><li>Allow a few minutes for setting up and shutting down the video conference.</li><li>Stick to time limits.</li><li>Remember to mute your microphone when you are not talking.</li><li>Consider using a location banner.</li><li>Take turns speaking and allow time for audio delay.</li><li>Don't multi-task on camera.</li><li>Be aware of possible audio distractions if your microphone is not muted - coughing, paper shuffling, air conditioning units, laptop and projector fans, phone ringing, etc.</li></ul>\r\n<span style=\"font-weight: bold;\">What are some suggestions for a successful video conference?</span>\r\nProvide an overview for new users so they can learn the basics of videoconferencing:\r\n<ul><li>Share rules of etiquette.</li><li>Get experience using the remote control (room based systems) or using the desktop client software.</li><li>Emphasize the importance of muting the microphone when you are not speaking.</li><li>Test with each location prior to the video conference.

This is in contrast to delivery through traditional terrestrial, satellite, and cable television formats. Unlike downloaded media, IPTV offers the ability to stream the source media continuously. As a result, a client media player can begin playing the content (such as a TV channel) almost immediately. This is known as streaming media.\r\nAlthough IPTV uses the Internet protocol it is not limited to television streamed from the Internet (Internet television). IPTV is widely deployed in subscriber-based telecommunications networks with high-speed access channels into end-user premises via set-top boxes or other customer-premises equipment. IPTV is also used for media delivery around corporate and private networks. IPTV in the telecommunications arena is notable for its ongoing standardisation process (e.g., European Telecommunications Standards Institute).\r\nIPTV services may be classified into three main groups:\r\n<ul><li>Live television and live media, with or without related interactivity;</li><li>Time-shifted media: e.g. catch-up TV (replays a TV show that was broadcast hours or days ago), start-over TV (replays the current TV show from its beginning);</li><li>Video on demand (VOD): browse and view items in a stored media catalogue.</li></ul>\r\nHistorically, many different definitions of IPTV have appeared, including elementary streams over IP networks, MPEG transport streams over IP networks and a number of proprietary systems. One official definition approved by the International Telecommunication Union focus group on IPTV (ITU-T FG IPTV) is:\r\n<blockquote><span style=\"font-style: italic;\">IPTV is defined as multimedia services such as television/video/audio/text/graphics/data delivered over IP based networks managed to provide the required level of quality of service and experience, security, interactivity and reliability.</span></blockquote>\r\n\r\nAnother definition of IPTV, relating to the telecommunications industry, is the one given by Alliance for Telecommunications Industry Solutions (ATIS) IPTV Exploratory Group in 2005:\r\n<blockquote><span style=\"font-style: italic;\">IPTV is defined as the secure and reliable delivery to subscribers of entertainment video and related services. These services may include, for example, Live TV, Video On Demand (VOD) and Interactive TV (iTV). These services are delivered across an access agnostic, packet switched network that employs the IP protocol to transport the audio, video and control signals. In contrast to video over the public Internet, with IPTV deployments, network security and performance are tightly managed to ensure a superior entertainment experience, resulting in a compelling business environment for content providers, advertisers and customers alike.</span></blockquote>","materialsDescription":" <span style=\"font-weight: bold; \">What is IPTV?</span>\r\nIPTV refers to Internet-based Protocol Television where the internet is used to deliver TV programs &amp; Videos that are either live or on-demand. IPTV is a system where digital television service is delivered to the subscriber through Internet protocol technology via the medium of broadband or internet connection.\r\nIt is slightly different from a digital video that is accessed by millions of users on sites or apps like YouTube or Netflix, but it shares quite a bit of the same ubiquitous, pervasive nature. Also unlike standard cable or satellite connection, in IPTV multiple TV sets can use a single subscription within a home.\r\nIPTV gives the viewers the added advantage and convenience of being able to pick the program they want to watch whenever and wherever they feel like watching it apart from tuning into any Live TV shows that are being aired currently.\r\n<span style=\"font-weight: bold; \">How does IPTV work?</span>\r\nIPTV is much similar like browsing the internet than traditional channel surfing. It merely uses IP (Internet Protocol), a transport protocol that is a delivery mechanism to deliver the videos to the viewer. When the viewer clicks on any TV program or requests the video, video from different sources (servers) is divided into data packets and sent over the internet. Video servers transmit programs through fiber-optic cable to existing households via internet connection and requests are sent out and shows are sent back.\r\n<span style=\"font-weight: bold; \">What is IPTV architecture?</span>\r\nDepending on the network architecture of the service provider, there are two main types of IPTV architecture that can be considered for IPTV deployment: centralized and distributed.\r\nThe centralized architecture model is a relatively simple and easy to manage solution. Because all media content is stored on centralized servers, it does not require a comprehensive content distribution system. Centralized architecture is generally good for a network that provides relatively small VOD service deployment, has an adequate core and edge bandwidth and has an efficient content delivery network (CDN).\r\nDistributed architecture is just as scalable as the centralized model, however, it has bandwidth usage advantages and inherent system management features that are essential for managing a larger server network. Operators who plan to deploy a relatively large system should, therefore, consider implementing a distributed architecture model right from the start. Distributed architecture requires intelligent and sophisticated content distribution technologies to augment the effective delivery of multimedia content over the service provider’s network.\r\nBroadcast content from Satellites and Local Antennas are received by the central unit. The central unit is where live TV channels and AV sources are encoded, encrypted and delivered in the form of IP multicast streams. The Central unit will also contain the Advertising Servers, Live TV Streaming Servers, Video on Demand (VOD) servers &amp; platform and is where on-demand video assets are stored and served as IP unicast streams when a user makes a request. The VOD platform may sometimes be located with and considered part of, the IPTV’s central unit.\r\nThe requested videos and TV Channels are delivered to the viewer via the delivery network which consists of a robust internet uplink via Fiber Optics from the IPTV broadcasters end.\r\nThe viewer will receive this signal at their end via their local or preferred internet service provider which can vary from a range of options like broadband, fiber optics, DSL, etc..\r\nWhen the viewer subscribers to a particular IPTV service they are provided with the service’s specific Set Top Box (STB). A set-top box is the piece of endpoint equipment that decodes and decrypts TV and VOD streams for display on the TV screen. This STB is connected to the viewers’ internet connection (router) and uses the internet to deliver the video and TV content to the viewer.\r\nThe viewer requests the videos or TV Channels via an interactive portal in the STB, that allows the viewer to navigate within the different IPTV services, such as the VOD catalog.\r\nWhile this is a typical example of an IPTV architecture model, due to a wide variety of service providers in the market today and the IT options available in the market, each service provider may decide to implement a slightly different architecture that suits their needs, geographic area, endpoint internet connectivity, local market conditions &amp; requirements, and business model.\r\n<span style=\"font-weight: bold;\">What are the types of IPTV services?</span>\r\nApart from transmitting classic TV channels, the following interactive services are also provided by IPTV:\r\n<ol><li>Video on Demand: Individual delivery of video content to a subscriber. It allows users to watch any movie from the VoD server’s media library.</li><li>Near Video on Demand: It is a pay-per-view video service intended for multiple users subscribed to nVoD service. The content broadcasting schedule is compiled beforehand and subscribers can look at the schedule and watch content according to their interest.</li><li>Time-shifted TV: Time-shifted TV lets subscribers view live broadcasts later so they can playback and resume at their convenience.
