Chapter 3: multimedia data compression page 5 adaptive compression is capable of adjusting to any type of data input and of returning output using the best possible compression ratio.

Data Compression Pdf Data Compression Code Huffman coding is an efficient method of compressing data without losing information. huffman coding provides an efficient, unambiguous code by analyzing the frequencies that certain symbols appear in a message. Introduction multimediafiles are large and consume lots of hard disk space. the files size makes it time consuming to move them from place to place over networks or to distribute over the internet. compressionshrinks files, making them smaller and more practical to store and share. compression works by: removingredundantinformation. A t ypical image compression system (or source enco der) consists of a transformer, quan tizer, and a co der, as illustrated in fig. 3.2. t ransformer applies a one to one transformation to the input image data. the output of the transformer is an image represen tation whic his 80 multimedia systems t echnology: co ding and comp ression ch. 3. Recursively apply the steps 3 and 4 to each of the two halves, subdividing groups and adding bits to the codes until each symbol has become a corresponding code leaf on the tree.

Dialogue mode requirements: compression and decompression in real time (e.g. 25 frames s) mode requirements: end to end delay < 150ms. The organization of the chapters is as follows: we introduce the mathematical preliminaries necessary for understanding lossless compression in chapter 2; chapters 3 and 4 are devoted to coding algorithms, including huffman coding, arithmetic coding, golomb rice codes, and tunstall codes. 2. data compression 2.1 storage space 2.2 coding requirements 2.3 basic compression techniques (run length& huffman encoding). Chapter 3 discusses the preliminaries of data compression, reviews the main idea of huffman coding, and shannon fano coding. chapter 4 introduces the concepts of prefix codes.
