METHODS AND DEVICES FOR DATA COMPRESSION USING CONTEXT-BASED CODING ORDER
摘要
<p>A method is presented for entropy coding data using an entropy coder to encode an input sequence. A context model is used to determine the context of each symbol and a probability estimation is made for each symbol. A method is presented for revising the coding order to be context-based, grouping symbols consecutively on the basis that they have a common context. A method is presented for entropy decoding a bitstream of encoded data encoded using a context-based coding order.</p>
