IPTV means television delivered using Internet Protocol networks. It describes a delivery method rather than a particular player, channel package or subscription. An IPTV setup normally involves a source of programmes, network delivery and software or hardware that plays the stream. Managed television networks and internet-based services can use different delivery arrangements.

A practical example
A household may use a television app to play a subscription supplied separately. The television, app and subscription each have their own settings and support responsibilities, even though the viewer experiences them together as one viewing setup.
A common misunderstanding
Do not assume that an app labelled IPTV includes programmes, that every service uses the same technology, or that a working player proves an account has access to particular channels.
