what  Mean  IPTV ?

IPTV Magazine identifies and explains the technologies and applications that allow television services... to be provided through Internet Protocol (IP) data networks. Readers learn the options and the system to implement IPTV along with new features and applications and business opportunities that are available in the IPTV industry today.         

IPTV Magazine explains how and why people and companies are using IP television and Internet television services. You will discover how global television services are already available through managed broadband networks (DSL and Cable modem) and unmanaged networks (the Internet) and how it is possible to use standard television to watch global television channels using analog television adapter boxes.

Through IPTV magazine, you will discover how IP television can be watched on different types of viewing devices such as standard televisions with adapters, dedicated IP televisions, multimedia computers and mobile telephones.

IP television service allows viewers to have more control of Internet television services. This control ranges from instant service activation to real time television on demand controls. Some of the advanced Internet television features such as personal media channels, anywhere television extensions, global television channels and multimedia programs are described.

In addition to the traditional ways of television channel selection, you will learn about new ways television channels can be search and selected using interactive electronic programming guides (EPGs). The different types of media formats that are used for IP television services are explained along with their control protocols.

Not all IPTV systems and services are the same. There are cost and quality tradeoffs along with common problem areas and risks. You will discover how the audio and video service quality can range from poor to above the quality that is already delivered to standard TV.

Because each IP television viewer has a unique address, this allows advertising messages to be sent to specific viewers (addressable advertising). The ability to direct advertising messages to specific target audiences (addressable advertising) is more valuable to companies than traditional broadcast advertising and this may result in reduced viewing costs.

Some of the most important topics covered in the magazine are:

- Fundamentals of how IPTV works

- How to use regular televisions to watch IPTV

- Global television channels

- Internet television service quality

- The costs of Television systems and services

- Control of Internet television services

- Internet television service providers

- Advanced Internet television features

- Electronic programming guides

- IPTV Media formats

How does IPTV work?

IPTV content is often delivered over a managed or dedicated network. Compared to the public internet, a private network gives network operators more control over the video traffic and, by extension, the ability to ensure quality of service (QoS), uptime and reliability.


In traditional television delivery, all programming is broadcast simultaneously. The available program signals flow downstream, and the viewer selects a program by changing the channel.


An IPTV service, by contrast, sends only one program at a time. Content remains on the service provider's network, and only the program the customer selects is sent to the residence. When a viewer changes the channel, a new stream is transmitted from the provider's server directly to the viewer. Like cable TV, IPTV requires a set-top box or other customer-premises device.


IPTV primarily uses IP multicasting with Internet Group Management Protocol (IGMP) for live television broadcasts and Real-Time Streaming Protocol (RTSP) for on-demand programs. Other common protocols include Real-Time Messaging Protocol (RTMP) and Hypertext Transfer Protocol (HTTP).

Types of IPTV

Because IPTV uses a packet-based delivery system, it can be bundled with other IP-based services, such as voice over IP (VoIP) and high-speed internet.

The use of IP also enables providers to support various other services and applications, such as video on demand, in-program messaging and timeshifting, a broad term for services that allow viewers to consume content other ways besides live broadcasts (e.g., digital recording, on-demand video and the ability to rewind or restart a live program already in progress).

IPTV competes with another delivery model known as Internet TV, which refers to television content distributed through a website.
