IPTV is not normal TV

Most of the telecommunication companies all over the world moving towards convergence in their network with triple play voice, video and data(broad band internet). IPTV which stands for Internet protocol TV is a technology that multicast TV channels and VOD on broadband networks.  bandwidth of the network plays a main role in the IPTV business. Other aspect of IPTV is the video encoding and compression mechanism used in video delivery. I have closely worked with UT starcom IPTV system which is called as UT Starcom's rolling stream IPTV system(http://www.utstar.com/). IPTV aand Satellite TV is two different technologies which are competing to the same market segment.

Let me explain the IPTV architecture first. First let's talk about  how live channels are transmitted over broad band networks. The trick play function on live channels, gives you the control over what you are watching. it gives you the pausing function where you can pause the live stream and go back in time. Time shifting is the term that is used in IPTV for going back in time to watch something already been telecast. Live channels get transmitted via satellite and fibers to the IPTV head end from television stations.
