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. Watch this short video and see the impact of packet loss, jitter and delay on video.
