A method for transmitting data using an embedded bit stream produced in a hierarchical tablelookup vector quantizer

摘要

A transmission method for video image data using an embedded bit stream in a hierarchical table-lookup vector quantizer comprises the steps encoding (12) an image using hierarchical vector quantization and an embedding process to obtain an embedded bit stream for lossless transmission. The bit stream is selectively truncated (20) and decoded (32) to obtain a reconstructed image. <IMAGE>
