Method and arrangement for scrambling image signals |
摘要 |
During transmission of image signals, the code words are scrambled with each other. However, the scrambling scheme changes continuously, so that decoding is almost impossible. In a variant of this method, the code words (CW) of the image signal (BS) are first divided into data blocks (DB), which are then scrambled with each other. <IMAGE>
