Abstract
Official abstract text for this publication.
A global bit stream comprising at least a first and a second bit stream is generated using an original visual bit stream. The first bit stream is generated by compressing the original visual bit stream using a JPEG-LS compression technique with a lossy factor ‘n’. The second bit stream is generated by compressing a difference bit stream using a JPEG-LS lossless compression technique, wherein the difference bit stream comprises a difference between the original visual bit stream and the first bit stream. The visual display is recreated using a reconstructed bit stream after receiving the global bit stream over a channel, wherein the reconstructed bit stream is generated by decompressing at least the first bit stream using a JPEG-LS lossless compression technique. The second bit stream is decompressed using JPEG-LS lossless compression technique and the quality of the display may be enhanced by adding the decompressed second bit stream.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: compressing a first visual bit stream, wherein the compressing includes receiving the first visual bit stream; compressing the first visual bit stream using a lossy JPEG-LS compression technique to create a first compressed bit stream, wherein the lossy JPEG compression technique has a lossy factor; determining a difference between the first visual bit stream and the first compressed bit stream to create a first difference bit strea…
