Analisa perbandingan kompresi data multimedia menggunakan Algoritma Huffman dan Lepel-Zip-Welch (LZW)

- Multimedia data is data that consists of numeric data, text, images, video and sound are used to convey information. As the development of the era, multimedia data is increasingly used used. Multimedia data are increasingly used in various fields ranging from daily activities, entertainment, education, research, and other. Now the data size is getting bigger so more spending bandwidth to transmit the data thus draining a variety of media. Because that to overcome the problem of data compression is used. This study tries to analyze lossless data compression algorithm with Huffman and Lepel-Zip-Welch (LZW). Performance the algorithms are tested using video data with the extension (.AVI), (FLV), (.MP4), text data with the extension (.PDF), (PPT), (.DOC), the image data with the extension (. PNG), (.TIF), (.JPG), (.aac), and voice data with the extension (.M4A), (.MP3), and (.WAV) From this research, the results of performance comparison of file compression uses algorithms Huffman and Lepel-Zip-Welch (LZW) where algorithms Huffman has a compression ratio of 32.464% while the algorithm Lepel-Zip-Welch (LZW) has a compression ratio dependent on the dictionary digunakanya, while the compression ratio is able to achieve 38.834%.. Keywords: Multimedia data, data compression, lossless, Huffman, lossy, Lepel-Zip-Welch (LZW)
