How to play videos from my iPhone 5 to my tv?

I have an iPhone 5 and I want to watch videos from it onto my tv. My tv is a widescreen Samsung, and I've put in my iPhone charge usb into the usb slot on the tv but that didn't work, so does anyone know how to?

You may refer to this step by step guide, it's about how to connect iPhone and iPad to TV, it works pretty well for my iPhone 5.
