发明名称 Adaptive entropy coding compression with multi-level context escapes
摘要 The performance (compression ratio) of an entropy coding compressor can be improved by separating its output into two streams: encoded output symbols compressed according to a probability model, and literal symbols that were not present in the probability model when the corresponding input symbol was to be encoded. The literal symbols are collected into a group and compressed separately. The compressed literals are stored at a discernable place relative to the encoded output symbols (e.g., at the beginning or end of the sequence of encoded output symbols).
