Lossless compression of digitized data such as video, digitized film, and audio preserves all the information, but it does not generally achieve compression ratio much better than 2:1 because of the intrinsic entropy of the data. Compression algorithms which provide higher ratios either incur very large overheads or work only for specific data sequences (e.g. compressing a file with mostly zeros). In contrast, lossy compression (e.g. JPEG for images, or MP3 and Opus for audio) can achie… Web24 de jan. de 2024 · A method for a compression scheme comprising encryption, comprising: receiving, as input, data comprising a plurality of data elements; constructing a Huffman tree coding representation of the input data based on a known encryption key, wherein the Huffman tree comprises nodes that are compression codes having …
