| 摘要 |
<p>The invention relates to a method of controlling decoder drift for memory compression comprising the steps of: providing a decoded bit-stream output of a decoder (79) and a bit-stream input to an encoder (76) in a first pass of a coding loop, where said bit-stream input to said encoder (76) is based on said decoded bit-stream output of said decoder (79); determining a difference between said bit-stream input to said encoder (76) and said decoded bit-stream output of said decoder (79), where said difference is due to a compression of said decoded bit-stream output of said decoder (79) in said encoder (76) during said first coding loop; and correcting said decoded bit-stream output of said decoder (79) in dependence on said determined difference in a second pass of said coding loop.</p> |
