APPARATUS AND METHOD FOR PRODUCING A DATA STREAM AND APPARATUS AND METHOD FOR READING A DATA STREAM |
摘要 |
The invention relates to an entropy encoder (10) for generating a data flow, which has two reference points consisting of variable-length code words. Sai d device comprises a first unit (16) for writing at least one portion of a cod e word into the data flow in a first direction of writing, starting from a fir st reference point, and comprises a second device (18) for writing at least one portion of a code word into the data flow in a second direction of writing which is opposite to the first directions of writing, starting from the othe r reference point. In particular, if a raster with multiple segments is used t o write the variable-length code words into the data flow, then in the best-ca se scenario the number of code words that can be written, beginning at the rast er points, is doubled in such a way that the data flow of variable-length code words is resistant with regard to the propagation of sequence errors.</SDOAB >
