Multimedia Data Compression Techniques

Integrated multimedia consist of text, graphics, audio and visual data. Data in uncompressed form requires more storage capacity and transmission bandwidth. The recent growth in web applications have not only need for efficient ways to encode signals and image but they have made compression of such signals central to storage and communication technology. Despite the technological advances in storage and transmission, the demand placed on the storage capacities and on bandwidth of communication exceeds the availability. Hence, compression has proved to be a valuable technique as one solution. The main objective of data compression is to represent the data as accurately as possible by using fewest numbers of bits. It is the process of compacting data in smaller number of bits. This paper surveys the features for image and video compression. The organization of paper as follows Section I contains the introduction part, Section II describes the component of compression, Section III covers the Compression techniques, Section IV defines the Features of Image Compression and section V describes Features of Video Compression, then the Section VI covers the benefits of compression.
