Abstract
Disclosed herein is an automatic ID allocation technique for use in AV/C device applications. The method allows ID assignment without manual user intervention. The method includes assigning an ID to an entity when called to do so upon detection of a new entity. Furthermore, old IDs are reallocated for later use upon disconnection of the associated entity.
