ABSTRACT:
Blocks of data, each representing ninety-six lines of a digital television signal are subjected to horizontal shuffling within each line and then to vertical shuffling within each block. The effect of the vertical shuffling is to displace sample words to different lines so that in the event of errors occurring during recording and reproduction in a video tape recorder, valid sample words are available adjacent to any error sample word for the purpose of error concealment. The vertical shuffling does not interfere with vertical parity generation or with the correction of errors after reproduction using the vertical parity words.
