ABSTRACT:
A system and method for processing and transmitting video imagery. The system permits the operator of a video image system to selectively transmit desired portions of the video image at an operator selected resolution, operator selected compression level, and operator selected order of transmission of each of the portions. The system also includes a novel method of retransmitting only those packets of data which have been erroneously transmitted and an automated retransmission protocol which retransmits data in a more robust manner where errors are detected in the first transmission of the data. Also disclosed in the system is a method of shading various portions of the video image to inform the system operator of which portions of the video image have been transmitted and a protocol for limiting the duration of and for altering the frequency of data transmissions to avoid detection and/or jamming by others.
