Abstract
A data transmission method and protocol includes progressive coding of a data set into time stamped data packets. The packets are ordered in importance, with some packets being more critical to received data quality than other packets from the same source. If packets are delayed in transit from a source to a receiver, packets of lesser importance are discarded after a set time, a transmission and decoding of a second set of time critical data begins.
