What is IPTV?
IPTV (Internet Protocol Television) describes technologies that allow video programming to be
delivered using an IP-based network, as opposed to traditional delivery via radio waves or coaxial
cable. IPTV can be used to deliver both live content and stored, on-demand video.
What is the potential of IPTV?
IP-based video distribution promises significant advantages, including the ability to integrate
television with other IP-based services like high speed Internet access and VoIP. Using a single
network for both data and video distribution potentially allows for significant savings over
maintaining a separate coaxial plant.
A switched IP network also allows for the delivery of significantly more content and functionality.
Content remains within a defined network, and only the content the customer selects is sent into
the customer's device. That frees up bandwidth, and the customer's choice is less restricted by the
bandwidth of the last-mile network.
An IP-based platform also allows significant opportunities to make the TV viewing experience more
interactive and personalized.
