Video compression formats typically use a technique known as ‘difference coding’ by comparing the difference between the current video frame with the preceding frame. This ensures that information which does not change (e.g. static background) is not repeatedly transmitted. To reduce network bandwidth, video is highly compressed, but losses affect quality.

If employers attempt to block, deny, or forbid mobile devices, social networks, instant communications, and new technologies in the work place employees will likely ignore the policies or, even worse, find ways around them that open your environment to unrealized risks.
