IFRAME – “IFrame (from inline frame) is an HTML element which makes it possible to embed another HTML document inside the main document. The size of the IFrame is specified in the surrounding HTML page, so that the surrounding page can already be presented in the browser while the IFrame is still being loaded. The IFrame behaves much like an inline image, and the user can scroll it out of view. On the other hand, the IFrame can contain its own scroll bar, independent of the surrounding page's scroll bar.
IPTV – Acronym for Internet Protocol Television, which delivers digital television service using the Internet Protocol over a network.
