Used Protocols

Protocols used in IPTV forecasting are the HTTP (Hyper Text Transfer Protocol), IGMP (IP Group Membership Protocol) and RTSP (Real Time Streaming Protocol). HTTP is the protocol that browsers use to communicate with the servers and computers for data transfer. Live TV uses IGMP version 2 for connecting television sets with the multicast stream and switching to another multicast stream while RTSP protocol is used for Video on Demand services.


There are two basic ways in which the material for IPTV can be handled. It can be sent out as broadcast or "multicast" material to many users simultaneously or it can be used to provide video-on-demand where the material is sent to just one subscriber who has requested that particular item.
It is also necessary to ensure that bandwidth is used efficiently. To achieve this, the IPTV video is compressed and two main formats are used for this. One is MPEG-2, and the other is the newer MPEG-4 standard. Of these the MPEG-4 standard is being used increasingly in view of its superior performance. 

What is IPTV? (Introduction)

There are now many ways in which television material can be delivered these days. One method that is set to make a huge impact is IPTV. As the name indicates, IPTV, or Internet Protocol Television, is based around the use of Internet Protocol, and this means that the service tends to be used in conjunction with telecommunications services of which broadband internet lines are the most widely used, although any service that can carry packet data can be used.

IPTV has many advantages. It provides a potentially lucrative market in view many telecommunications providers are looking keenly at the possibilities of providing new services and generating new revenue streams. This means that in the years to come IPTV seems certain to become a major player in the entertainment market.
