System for managing data in a distributed computing system

A receiving device comprising:

• receiving circuitry configured to:
• receive a first module which identifies a plurality of modules for use by an application;
• receive said plurality of modules;
• and
• receive additional data corresponding to said application, wherein said additional data identifies fewer than all of said plurality of modules and identifies an update to be made to one or more of said first module and said plurality of modules;
• a processing unit configured to perform said update.

A broadcast station comprising:

• an server configured to convey data for use by an application;
• a transmitter configured to convey data for broadcast;
• and
• a processing mechanism configured to:
• generate a plurality of modules corresponding to said data;
• generate a first module which identifies said plurality of modules;
• convey said first module and said plurality of modules;
• and
• determine a change to said plurality of modules is required;
• generate a second module which identifies fewer than all of said plurality of modules and which identifies said change;
• and
• convey said second module.

A computer accessible medium comprising program instructions, said instructions being executable to:

• receive a first module which identifies a plurality of modules for use by an application;
• receive additional data corresponding to said application, wherein said additional data identifies fewer than all of said plurality of modules and identifies an update to be made to one or more of said first module and said plurality of modules;
• and
• perform said update.
