What Is IPTV And How It Works

Sometimes referred to as Smart TV," IPTV (Internet Protocol TV) is a transmission protocol that delivers television programming over a managed network by sending packet data via a high-speed Internet connection instead of an antenna, satellite, or cable. The IPTV provider also has the ability to add much more programming or data choices than can a cable system provider which is not using IPTV. IPTV is strictly baseband, while cable uses broadband modulation methods. Rather than streaming content directly to your browser, IPTV content goes from your router to a set-top box to display on your TV.

Different with IPTV, where UDP is used to carry the traffic, most other Internet applications such as HTTP, FTP, and SSH, and so forth, use TCP as the transport layer protocol. There are two main types of satellite TV on market today: TVRO (television receive-only) and DBS (direct broadcast satellite, or direct to home" DBSTV).

Over the last decade, the growth of satellite service, the rise of digital cable, and the birth of HDTV have all left their mark on the television landscape. You can watch programs that have been broadcast on www.youtube.com about a dozen different TV and radio channels in the last seven days (and occasionally for longer).

Even if you've never heard of IPTV before there's a good chance you've already used it without even knowing it. Actually, anyone who has watched live TV channels or a Video on Demand through their digital television service has experienced IPTV in its essential form.

IPTV (Internet Protocol Television) is a system where digital television services are delivered over the internet by using Internet Protocol. The architecture of the content-based IPTV service should first allow for comprehensive services. And video services to its rapidly growing IPTV subscriber base in Sweden.

A prime example of Cable TV is Time Warner Cable that is delivered via coaxial cable connection and an example of Satellite TV is from providers like DirecTV that is transmitted and delivered to the viewers via radio waves. Non-regulation also creates an opportunity for telecommunications and program and entertainment service providers outside the traditional cable industry to deliver video services to consumers.

To remedy this situation, we are going to spend today's blog explaining the exact process that Internet Protocol television follows. Most modern cable systems are hybrid fiber-coaxial networks, essentially the same as the hybrid fiber-coaxial network that delivers broadband cable Internet to your house.

Most video enters the system at the telco's national headend, where network feeds are pulled from satellites and encoded if necessary (often in MPEG-2, though H.264 and Windows Media are also possibilities).

This requires a system that can gather large amounts of data from multiple sources, including test probes installed at critical locations in the network, reports from system operators who are monitoring signals, and inquiries from users who are experiencing troubles.

This stream is typically controlled by the Real Time Streaming Protocol (RTSP), which enables DVD-style control over a multimedia stream and allows users to play, pause, and stop the program they are watching. IPTV has been widely used since around 2002 to distribute television and audio-visual (AV) media around businesses and commercial sites, whether as live TV channels or Video on Demand (VOD).
