ABSTRACT:
A communication system and protocol uses retransmission techniques for video transmission on mobile/wireless channels. The system partitions frames of a moving image into frame segments, and combines a sequence of frame segments to form a sub-sequence of the moving image. The sub-sequences are treated as separate images which are separately encoded and transmitted to a receiver and then are combined to reassemble the moving image. A sender transmits to the receiver data packets, each data packet representing all or part of a digital code for a frame segment. The receiver requests retransmission of data packets containing detectable errors, indicates in a status buffer which digital codes have been received and whether the digital codes are intra or inter codes, and displays a frame only after all required data packets have been received without detectable errors. The segmented frames limit occasional failures to accurately retransmit data to individual sub-sequences, so that the failure to accurately transmit data is compensated for by subsequent transmission an intra coded digital code for a frame segment.
