Managing Application Sets 

4011043 Rev B 

The efficacy of having groups with different priorities depends on the receiver 

characteristics. Taking start-up behavior as an example, if the receiver only loads the 

modules it needs, collecting the start-up objects together in a group of high priority 

will reduce start-up latency. However, if the receiver loads the whole object carousel 

before starting the application, having groups of different priorities will increase the 

time taken to start the application. 
Module compression works well for textual data but not for pre-compressed data 

like JPEG files.
