Video terminologies

In the coming articles, I will discuss things about our existing and future projects.  I definitely see myself using terminologies that will sound Greek to a lot of our readers.  Before this happens, I'd like to explain some basic video related terminologies that is sure to pop out time and time again.

The definitions below are layman definitions

Pixel    - Contraction of the words picture and element.  The smallest item of information in a picture.  It's essentially a colored dot.  A series of dots would form a line, clumps of it will form a picture of parts of it.  The number of pixels arranged horizontally and vertically is equivalent to the resolution.
