INTERNET PROTOCOL TELEVISION (IPTV)The Origin Of IPTV A TRIPLE PLAY SERVICES Triple Play service is a concept that delivers digital television broadcast, a telephone, and an Internet access to people through a single broadband connection IPTV Television Internet Broadcast Telephone AccessTRIPLE PLAY SETUP USING ADSL MODEM SPLITTERTriple Play Services  Triple Play means the delivery of voice, data and video over a single access subscription.  An IPTV broadband network can handle all three (voice, data, and video) services.  The common applications are Telephony, Television and highspeed internet services.  The telephony option offers call services such as call forwarding, caller ID, call waiting, call screening, selective call blocking and call conferencing.IPTV  A settop box (STB) is an IPTV device that is commonly used to receive and decode digital television broadcast and to SetTop turn the signal into content which is then displayed on a Box television screen or other display devices. (STB)  Professional settop box: Professional settopboxes referred to as Integrated Receiver Decoders or IRD are the professional method of the broadcasting video and audio contents to the television or other display devices.Hybrid IPTV settopboxes: This kind of IPTV settopboxes allow viewers to view broadcast television and internet video on their display screen along with IPTV services such as VOD and internet browser by creating a new consumer TV experience. Wireless IPTV settop box: Wireless IPTV setbox is designed to deliver IPTV contents over a wireless network connection.Introduction “IPTV is defined as multimedia services such as 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.” •In simple terms, IPTV is video and audio delivered over an Internet connection. You can watch IPTV on a computer screen, a television screen (through a settop box) or a mobile device like a cell phone or an iPod. •In the IPTV system, a video signal will be divided into multiple IP packets and then the packets will be sent across the IP network.Endtoend view of an IPTV network.Discussion of IPTV •IPTV Broadcast are transmitting their broadcast signal over the Internet. And require only an Internet connection and an Internet enabled device such as a PC, HDTV connected to a PC or even a 3G cell/mobile. •IPTV uses standard networking protocols, it promises lower costs for operators and lower prices for users. •IPTV doesn't require to install new Ethernet wires and without relying on wireless technologies like 802.11, which are not optimized for reliable delivery of video streams.Architecture of IPTVArchitecture of IPTV Distribution servers: They provide caching and QoS control VoD creators and servers: They retain a library of encoded VoD content to provide VoD services. IP routers: They route IP packets and provide fast reroute in case of routing failures. SetTopBoxes (STB): A STB is a device on the customer side that interfaces with the user terminal (e.g., TV, PC, laptop, and others) with a DSL (Digital Subscriber Line) or cable wiring.IPmulticast IPTV Architecture IP multicast is a method of sending IP packets to a group of interested receivers. IP multicast uses network infrastructure efficiently by requiring the source to send a packet only once, even if it needs to be delivered to a large number of receivers. A TV program is encoded at the super hub office (SHO), and then delivered via multicast through video hub offices (VHOs), intermediate offices (IOs), central offices (COs), digital subscriber line access multiplexers (DSLAM), and residential gateway (RG), to the TV settopboxes (STB).Continued…..  SHO is for acquisition of national live TV programs. Live TV programs are received via satellite and processed for delivery to multiple VHOs.  VHOs are the video distribution points within each demographic market area (DMA).  IOs and COs are located at each metropolitan area and connect to access networks.IPmulticast IPTV Architecture Architecture of a Peerto Peer IPTV system PeertoPeer IPTV Architecture For a PeertoPeer (P2P) IPTV distribution, there is a source and a group of peers watching the video. We refer to the source and the group of peers as a torrent. The source encodes video and disseminates the video packets into the P2P torrent. Each peer receives packets from the source . A mobile IPTV prototype has been designed and implemented to support users via wireless and mobile networks inIMS architecture for IPTV  IMS (IP Multimedia Subsystem) is an architectural framework for delivering IP multimedia to fixed and mobile users.  The benefits are, it can offer both voice and IPTV services over the same core infrastructure and enables the implementation of services combining conventional TV services with telephony features (e.g. caller ID on the TV screen) .  This architecture uses centralized server network for efficient CDN.  Use of this architecture enables the efficient broadcast of Hybrid IPTV.IMS Architecture for IPTVProtocols • Video content is compressed using either a MPEG2 or a MPEG4 codec. • Live IPTV uses IGMP version 2 or IGMP version 3 of IPv4 for connecting from one TV channel to another. • IGMP operates within LAN's or VLAN's so other protocols. • VOD uses UDP or RTP protocols for channel streams.Advantages • Ability to integrate television with other IPbased services like high speed Internet access and VoIP. • Support maximum data speeds of 50 Mb/s to 100 Mb/s. • Make the TV viewing experience more interactive and personalized, provides the functionality such as pause, slowmotion, rewind, freeze, store etc. • Large memory is available as the recorded data can be stored on servers provided by service providers.Applications • Electronic messaging and social networking. • Home security and management services. • Integration with VoIP for TV display of call, information and call routing, caller ID and blocking, call forwarding. • Sharing of photos, movies, and interests. • Personal TV channels. • Weather forecast, sports, recipes, etc. • Sports participation and gaming. • Blogging etc….THANKS Any questions You can find us at
