IPTV (Internet Protocol television)

IPTV (Internet Process television) is a service that provides television set programming and other video content while using the TCP/IP protocol suite as opposed to classic cable or satellite signals.
An IPTV service, typically distributed by a service supplier, delivers live TV programs or even on-demand video content. An IPTV system may be used to offer video content over a private system in an enterprise, although such implementations are far less common than subscriber-based models due to the complexity and climbing issues.
How does IPTV work?
IPTV content is often supplied over a managed or dedicated community. Compared to the public internet, a private community gives network operators more control of the video traffic and, by off shoot, the ability to ensure the quality of service (QoS), uptime and reliability.
In traditional television delivery, most programming is broadcast simultaneously. Typically the available program signals flow downstream, and the viewer selects a program simply by changing the channel.

An IPTV assistance, by contrast, sends only one program at the same time. Content remains on the service provider's network, and only the program the customer picks is sent to the residence. If a viewer changes the channel, a brand new stream is transmitted from the provider's server directly to the viewer. Such as cable TV, IPTV needs a set-top Entertainment Box or another customer-premises unit.
IPTV largely uses IP multicasting with Web Group Management Protocol (IGMP) intended for live television broadcasts and Current Streaming Protocol (RTSP) for on demand programs. Other common protocols incorporate Real-Time Messaging Protocol (RTMP) together with Hypertext Transfer Protocol (HTTP).
Types of IPTV#@@#@!!
Because IPTV uses a packet-based delivery system, it really is bundled with other IP-based services, just like voice over IP (VoIP) and high-speed net.
The use of IP furthermore enables providers to support various other companies and applications, such as video upon demand, in-program messaging and timeshifting, a broad term for services that will allow viewers to consume content different ways besides live broadcasts (e. h., digital recording, on-demand video as well as the ability to rewind or restart a new live program already in progress).
IPTV competes with another delivery model called Internet TV, which refers to tv set content distributed through a website.
IPTV providers
IPTV providers will include a wide range of companies from large community operators like Verizon with its FiOS services and massive companies like Yahoo, Apple and Microsoft, to distributors that include Sony, and a wide variety of smaller sized or niche companies sometimes devoted to certain types of content delivered on the broadband IP connection.
