Abstract
A method and apparatus for improving the efficiency of providing updated data over a transmission medium. Each data has associated information indicating the presence or absence of validity data. An absence of validity data indicates that the data does not need to be updated. The presence of validity data allows only that data which needs updating to be transferred on the transmission medium, thereby improving its performance.
