IPTV is a relatively new term that is being used often today. Internet Protocol television is simply the delivery of digital television content over Internet Protocol (IP) networks. Unlike delivery over traditional cable, satellite, and terrestrial television formats, IPTV provides the capability to stream the same content that is watched continuously from anywhere on the planet to an IP television receiver. The technology is similar to VOD–the video on demand that is delivered directly to a television set.
What is important to note is that many people are not familiar with the term IPTV. For this reason, there has been a great deal of misinformation circulating on the web about the potential benefits of this service. Much of this information comes from sites that are misguiding consumers about the type of features that are enabled by standard cable and satellite television providers. For example, while it is true that both IPTV and traditional broadcast television can deliver live streaming video, they serve very different purposes moiptv.net.
In order to understand IPTV, one must understand how the delivery works. As previously mentioned, IPTV consists of a central unit that broadcasts IP streams are routed to receivers. These IP streams are typically in the form of packets, or packets of data sent in the direction of the network of end users. This network is made up of computers that have internet connection capabilities. Each of these computers can be used to view live tv channels, control their own online streaming videos, and to connect to their personal computers that have satellite tv software installed.
In order to take full advantage of the capabilities of the internet protocol, the central unit needs to be equipped with some specialized hardware. It is this component that delivers the video stream to the IPTV receiver. Typically, this device is a small hand held device that is called an opt card. The iptv card may also be referred to as a tuner or an ip address keying device. It is an integral part of the entire IPTV architecture.
Another piece of hardware that is necessary for the complete process of IPTV is a set-top box or a traditional TV box. A set-top box is often referred to as a digital broadcast receiver. These devices function very similar to a conventional tv box, and they perform the same basic functions. However, since they implement IPTV technology, they also permit internet protocol capable video streams to pass through them directly to the IPTV receiver.
The final component of the IPTV architecture is the IPTV gateway. This device allows the user to connect to and receives information from an IPTV service provider. This connection is accomplished using a simple IP based protocol such as ICMP or TCP. To make the IPTV service more attractive, most providers bundle high speed internet access with their IPTV services. In addition, it is very common for IPTV services to be supported through downloadable software applications.
