Abstract
An output stream can be generated of compressed textual data. A first portion of the output stream includes an indicator that compression is used and a second portion is the compressed textual data. The textual data can be compressed by processing each byte of an input text bit-by-bit in order from most significant bit to least significant bit to generate an n-byte length context and a word context. While processing each byte, a subsequent bit is predicted based on the n-byte length context and a corresponding prediction model, and the subsequent bit is predicted based on the word context and a corresponding prediction model. The predictions can be combined to generate a final prediction. If the final prediction determines the subsequent bit, then the subsequent bit can be skipped in the output stream. The output stream can be provided to another device over a communication interface.
