Technical definition

With Internet TV streams are sent over the Internet globally accessible. Internet TV is different from Internet Protocol Television (IPTV ), in particular by the lack of support of a technical QoS (Quality of Service ), which is guaranteed in the TV or IPTV range from the manufacturer. As Internet TV uses the Internet as a transport route and is available on the World Wide Web, the provider can not guarantee transmission quality according to the " best effort " principle.

Due to the different bandwidths of the users, the transmission quality is aware beyond the control of the provider. The responsibility for the choice of suitable ( compatible ) devices and the choice of a suitable Internet access thus lies with the user. The responsibility for the availability of the infrastructure lies with the internet service provider who has to manage within its terms of reference the data as " over-the -top content" ( without content control). The provider of Internet television thus bears no responsibility for the entire transmission outside of its server infrastructure.

For the transmission of Internet television, a network connection from the sender via the Internet streaming server is established to the receiver of the viewer ( unicast). This whole TV programs or specific video posts (often encrypted with DRM method ) will be transmitted using Internet protocols ( see Streaming media ).

For example, a movie may not be broadcast from a transmitter only in licensed distribution area, which excludes the worldwide dissemination on the Internet. The other hand, is unproblematic self-produced material.

Some stations (mainly interest channels such as television Servus TV or ERF ) to license foreign material world, therefore, in order to realize a complete Live Stream. Transmitters such as Phoenix spread its own live stream depending on license intermittently. Information and regional channels have an advantage here, as the self-created posts of rights of third parties are free and fed delivered material consists mainly of advertising or agency fees, which may be spread throughout the world, usually without significant additional costs. The situation is different for music television such as Yavido, as the rights to the video clips are settled here, similar to the radio or a lump sum on the number of concurrent requests. Some transmitters such as n-tv make the start of the live stream above an advertisement to refinance the additional cost of the infrastructure ( at least partially ).
