Active / Passive 3D - The 2 different technologies of 3D TV.
Active uses glasses that 'flicker' alternate eyes open and shut to match the TV frames. Usually bigger, heavier glasses that require a small battery to power them.
Passive uses filters that are polarised different from each other, There are no batteries and are lighter to wear.
Both types work well but technically Active is better, being capable of the full frame resolution.
SMART - 'smart' devices can connect to the internet, Giving great features such as BBC iPlayer, Demand 5, YouTube, Netflix, Skype, Facebook and Twitter amongst other things.
