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