First Claim
Patent Images
1. In an audio/video controller entity, an automatic ID allocation method for audio/video control entities, the method comprising:
- providing a list for currently allocated audio/video control entities;
when an audio/visual control entity is initialized, allocating a current identifier value to the initialized entity;
searching the list to see if a value matching the current identifier is contained in the list;
if a value matching the current identifier is contained in the list, then until the current identifier value does not match a value contained on the list;
incrementing the current identifier value; and
checking the list to see if the incremented value is contained in the list;
if the current identifier value is not contained in the list, then adding the current identifier value to the list.

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.
