A method for decoding a video stream is described. The method comprises: receiving a video stream at a server application, the video stream being encoded according to a multi-layer coding scheme; passing, to a base decoder, an encoded base stream comprised by the video stream, for obtaining a decoded base stream; and passing, to an enhancement decoder, an encoded enhancement stream comprised by the video stream for decoding, wherein an original input video may be reconstructed from the decoded base stream and the decoded enhancement stream.
