WebbFor lossless data compression of multimedia, the Shannon-Fano Algorithm is an entropy encoding method. It gives each symbol a code depending on how often it is to occur, … WebbFeatures. The LZ4 algorithms aims to provide a good trade-off between speed and compression ratio. Typically, it has a smaller (i.e., worse) compression ratio than the similar LZO algorithm, which in turn is worse than algorithms like DEFLATE.However, LZ4 compression speed is similar to LZO and several times faster than DEFLATE, while …
