* Interactivity - An IP-based platform also allows significant opportunities to make the TV viewing experience more interactive and personalized.* Video on Demand (VoD) - permits a customer to browse an online movie catalogue, to watch trailers and to select the movie he wants to watch.* Converged Services - Another advantage of an IP-based network is the opportunity for integration and convergence. Converged services implies interaction of existing services in a seamless manner to create new value added services. One good example is On-Screen Caller ID, getting Caller ID on your TV and the ability to handle it (send it to voice mail, etc)
Limitations:
Because IPTV is based on the Internet Protocol, it is sensitive to packet loss and delays if the IPTV connection is not fast enough.
