Unit 2 Pdf 2. data compression 2.1 storage space 2.2 coding requirements 2.3 basic compression techniques (run length& huffman encoding). Dialogue mode requirements: compression and decompression in real time (e.g. 25 frames s) mode requirements: end to end delay < 150ms. Applications of data compression generic file compression. files: gzip, bzip, boa. archivers: pkzip. file systems: ntfs. Thus run length encoding, for example, can be used for compression of any type of data in a file system, for example, text, still images for facsimile, or as part of motion picture or audio coding.

Data compression unit 2 part 1 | aktu data compression | unit 2 one shot | huffman coding algorithm. 2.1.2 predictive coding differential coding data in order to make them more suited for subsequent compression. differential coding changes the statistics of the signal – based on the fact that neighbouring samples in digital data are often similar or highly correlated, differential coding does not compress the sequence of original data. This 2 bit field defines the version number. the current version is 2. p. this 1 bit field, if set to 1, indicates the presence of padding at the end of the packet. in this case, the value of the last byte in the padding defines the length of the padding. padding is the norm if a packet is encrypted. there is no padding if the value of the p field is 0. Huffman coding is a lossless data compression algorithm. the idea is to assign variable length codes to input characters, lengths of the codes are based on the frequencies of characters. the greedy idea is to assign the least length code to the most frequent character.
