Elements[ edit ] IPTV head-end: Video on Demand VOD platform: User equipment that can request, decode and deliver IPTV streams for display to the user.
This can include computers and mobile devices as well as set-top boxes. Architecture of a video server network[ edit ] Depending on the network architecture of the service provider, there are two main types of video server architecture that can be considered for IPTV deployment: The centralised architecture model is a relatively simple and easy to manage solution.
Because all media content is stored in centralised servers, it does not require a comprehensive content distribution system. Centralised architecture is generally good for a network that provides relatively small VOD service deployment, has adequate core and edge bandwidth and has an efficient content delivery network CDN.
Distributed architecture is just as scalable as the centralised 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 effective delivery of multimedia contents over service provider's network. This scenario becomes very common as service providers start to offer service packages with multiple set-top boxes per subscriber.
Networking technologies that take advantage of existing home wiring such as power lines,   phone lines or coaxial cables   or of wireless hardware have become common solutions for this problem, although fragmentation in the wired home networking market has limited somewhat the growth in this market.
Carriers will be able to offer both voice and IPTV services over the same core infrastructure and the implementation of services combining conventional TV services with telephony features e.
Playback requires a broadband device connected to either a fixed or wireless IP network in the form of either a standalone personal computer or limited embedded OS device such as a smartphonetouch screen tabletgame consoleconnected TV or set-top box. Video compression is provided by either a H.
IP multicasting allows for live data to be sent to multiple receivers using a single multicast group address. In standards-based IPTV systems, the primary underlying protocols used are: IGMP for subscribing to a live multicast stream TV channel and for changing from one live multicast stream to another TV channel change.
IP multicast is usually routed in the network core by Protocol Independent Multicast PIMsetting up correct distribution of multicast streams TV channels from their source all the way to the customers who wants to view them, duplicating received packets as needed.
On-demand content uses a negotiated unicast connection. Web -based unicast only live and VoD streaming: Web-based multicast live and unicast VoD streaming: Connected TVsgame consolesset-top boxes and network personal video recorders: Web-based content is provided through either inline Web plug-ins or a television broadcast-based application that uses a middleware language such as MHEG-5 that triggers an event such as loading an inline Web browser using an Adobe Flash Player plug-in.
A telecommunications company IPTV service is usually delivered over an investment-heavy walled garden network.
Local IPTV, as used by businesses for audio visual AV distribution on their company networks is typically based on a mixture of: Via satellite[ edit ] Although IPTV and conventional satellite TV distribution have been seen as complementary technologies, they are likely to be increasingly used together in hybrid IPTV networks that deliver the highest levels of performance and reliability.
The copper twisted pair cabling that forms the last mile of the telephone and broadband network in many countries is not able to provide a sizeable proportion of the population with an IPTV service that matches even existing terrestrial or satellite digital TV distribution.
Satellite distribution can be included in an IPTV network architecture in several ways.In his recent speech at the Asian Institue of Management, Patalinghug stressed that crucifying the current Globe versus PLDT rivalry will be both unfair and illogical.
