Round 1: Tossup 17

This process cannot decrease the code rate below the Shannon entropy according to the source coding theorem. Abraham Lempel and Jacob Ziv developed this process’s LZ77 (15[1]-5[1])algorithm, which is combined with Huffman coding in an algorithm nicknamed (15[1])DEFLATE. (15[1])Some algorithms for this process allow for (-5[1])perfect reconstruction by removing redundancies without removing (*) information. Unlike PNG files, JPEG files use a “lossy” form of this process (10[1])that creates rectangular artifacts. Folders subjected to this process become ZIP files. For 10 points, name this process that reduces a data file’s size. ■END■ (10[1])
