Definition of "LZ78" |
refers to string-based compression schemes based on Lempel and Ziv’s 1978 method. A dictionary of prefix strings is built at the encoder and decoder progressively, based on the message. The encoder searches the dictionary for the longest string matching the current input, then encodes that input as a dictionary index plus the literal symbol which follows that string. The dictionary entry concatenated with the literal is then added to the dictionary as a new string. |
