摘要： The present invention relates to an apparatus and a corresponding method for de-mapping a time-domain de-mapping input data stream (Q') having a frame structure into at least two de-mapping output data streams (S1', S2',..., Sn') carrying error correction code encoded time-domain data, comprising a data input (202) for receiving said time-domain de-mapping input data stream (Q') having a frame structure of frames, each frame comprising a number of frame intervals (F1, F2,..., FM), wherein each frame interval carries sequentially arranged data blocks (D1, D2,..., DN) from various de-mapping output data streams and wherein within a frame the mapping of data blocks (D1, D2,..., DN) from the various de-mapping output data streams onto frame intervals (F1, F2,..., FM) is different from frame interval to frame interval, a data de-mapper (206) for de-mapping the frames of said de-mapping input data stream (Q') into said at least two de-mapping output data streams (S1', S2',..., Sn'), wherein from frame interval to frame interval within a frame the de-mapping of data blocks (D1, D2,..., DN) into said at least two de-mapping output data streams (S1', S2',..., Sn') is made differently, and a data output (210) for outputting said at least two de-mapping output data streams (S1', S2',..., Sn').
