Compression methods utilized for digital video can be categorized in three major groups:

• General reason compression techniques can be utilized for any type of data.
• Intra-frame compression techniques work upon images. This compression applied to even images, as photographs and diagrams and exploits the redundancy inside the image, termed as spatial redundancy. Intra-frame compression techniques can be applied to particular frames of a video sequence.

Inter-frame compression techniques work upon image sequences quite than particular images. Generally, relatively little changes from one video frame to the subsequently. Inter- frame compression develops the similarities among successive frames, termed as temporal redundancy, to decrease the volume of data required to explain the sequence.
