ABSTRACT:
A still video transceiver processor, which transmits or receives serial data segments of a compressed video frame, includes a segment information array which tracks the current state (sent
ot sent) and status (acknowledged/unacknowledged) of each compressed segment and the address of the corresponding uncompressed image blocks in the video frame. The segment information array enables the transceiver processor to deduce whenever a transmitted segment must be retransmitted over one of two channels in response to a negative acknowledgement received over the other channel, and assures proper placement of the uncompressed (expanded) image blocks in the video frame of the receiver unaffected by out-of-order retransmission of any data segments.
