What does smart TV mean?
Like a smartphone, a smart TV offers a number of "internet connected services" that normal televisions can't offer. It has the equivalent of a computer built into it, giving you a greater number of services. These televisions offer apps, media streaming, web browsing, games and, perhaps most importantly, Internet Protocol Television (IPTV). IPTV is a specific type of internet video standard, but is now also used as shorthand for any video streamed via the internet to your TV. It can take the form of short clips or continuous "live" channels.
While these features aren't new, and have been a part of some televisions and set-top boxes since 2005, the term "smart TV" has given them a name.
