Compression
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...

| Zusammenfassung: | 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. |
