| 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 the bit-stream input to the encoder ( 76 ) is based on the decoded bit-stream output of the decoder ( 79 ), determining a difference between the bit-stream input to the encoder ( 76 ) and the decoded bit-stream output of the decoder ( 79 ), where the difference is due to a compression of the decoded bit-stream output of the decoder ( 79 ) in the encoder ( 76 ) during the first coding loop and correcting the decoded bit-stream output of the decoder ( 79 ) in dependence on the determined difference in a second pass of the coding loop.</p> |
