Abstract:
1. Method for producing a data stream of code words of variable lengths which are divided up into a plurality of sets of code words, a raster having raster points existing for the data stream, two adjacent raster points defining one segment, and the raster comprising a plurality of segments, the method including the following steps: encoding an audio signal generating the code words of variable lengths, the code words of variable lengths representing the audio signal; a1) writing the code words of the first set such that starts of the code words are at raster points of different segments; b1) in case the respective code word fits in the segment, writing each code word of the second set into a segment which is assigned to each individual code word pursuant to a predetermined assignment rule, wherein each code word of the second set is assigned a different segment pursuant to the predetermined assignment rule; b2) in case only a part of the respective code word fits in the assigned segment or in case the assigned segment is full, writing the part of the respective code word of the second set into the assigned segment and storing the remainder of the code word or, in case the assigned segment is full storing the entire code word which is assigned the full segment; b3) writing the stored remainder or the stored entire code word, which did not fit in the respective segments in steps b1), b2), into an area of the raster which is not written onto after steps b1) and b2), pursuant to a second predetermined regulation, until all code words of the second set have been written into the raster.
