发明名称 VERFAHREN ZUR KORREKTUR VON BLOCKWEISE UEBERTRAGENEN DISKRETEN WERTEN.
摘要 To correct for errors arising in the transmission of discrete values in block form, correcting values are added. Before and/or after transmission the multiplication of values takes plate and the resulting products are truncated with respect to the allowed index number or significant number of places. To compensate for these truncations correcting values are added to the products. When transmitting picture information the time domain values are transformed into the frequency domain. After transmission the blocks of frequency domain values are transformed back into picture values (i.e. time domain).
