Abstract: An application is signaled to a host device using descriptors incorporated into an application information table. Only applications intended for a certain host device are downloaded to that host device. The descriptors allow the host to identify applications that are addressed to the host based on attributes of the host. When addressing is performed at the level of an application, the application signaling is accomplished using a single application information table and the evaluation of logical parameters against selected host attributes to identify all of the applications addressed to the host. When addressing is performed at the level of a table, multiple tables are evaluated using logical parameters applied to selected host attributes to determine which table is addressed to the host. Addressing conflicts are resolved using priority measures assigned to selected host attributes.
