In the age of modern network infrastructures and convergence to the Next Generation Network (NGN) or ALL-IP network, well-known services such as linear television, which has previously been aired by the TV stations on cable, satellite or terrestrial via broadcast, are now being ported via new transmission media.
The most common designation for television which is broadcast or received via the Internet is “Internet Protocol Television” (IPTV). IPTV generally designates the digital transmission of audio and video signals via a broadband Internet connection.
Through the broadband Internet connection, genuine interaction with the consumer is possible, through which new applications and services such as video-on-demand (VoD) can be realised.
At the same time, there is a trend for end users on the Internet to use platforms such as “YouTube” and “Amazon Prime Instant Video” as video portals for their daily consumption of video material. On the same basis, services such as “Zattoo” which conquer the market and enable live television via the internet.
We need to differentiate clearly between IPTV, WebTV and video portals, although they all provide a video format customised to the service, which is specially encoded and packaged in containers and delivered locally or globally to the consumer.
