Future global broadcast systems (GBS) using high power digital direct broadcast satellites (DBS) will need to accommodate a large and continuously growing number of users. This user community will have extremely diverse information needs and diverse information processing capabilities. The number of sources of information will also become very large. The GBS route of information distribution is a reliable and inexpensive method to distribute large volumes of data to large numbers of users simultaneously. The GBS community of information providers and information consumers is, like the Internet, starting out tightly controlled by the United States Department of Defense. The example of the Internet has taught us that information distribution technologies will continue to be in growing demand by a very wide community. The challenge to wide use of GBS is how to control distribution of, and access to, broadcast data products. Hierarchical information management (HIM) is a method to allow diverse users of GBS to have individualized access to data that is appropriate for them to receive and fits their domain of interest. HIM will also ensure that their data processing equipment can process or view the data products.
