Abstract
A method to reduce the computation and bandwidth costs for a broadcasting incremental changes to the states of topics in a data distribution system. Publishers transmit updated states to the data distribution system server and the data distribution system server calculates a binary delta between the received updated state and the current state of the topic. The data distribution system server publishes the updated state to the topic in a topic tree maintained on the data distribution system server and broadcasts the binary delta to clients that are subscribed to the topic. Using the received binary delta, the subscribed clients calculate the updated state.
