ABSTRACT:
A modified AV/C command set includes status inquiry, notify inquiry and control inquiry commands. The status inquiry, notify inquiry and control inquiry commands include an opcode and any number of operands. Thus, the status inquiry, notify inquiry and control inquiry commands can include only an opcode. The status inquiry, notify inquiry and control inquiry commands are sent from a controller to a target device to determine if the target device supports a particular status, notify or control command, respectively. In response to a status inquiry, notify inquiry or control inquiry command, a target device sends a response to the controller notifying the controller as to whether or not the target device supports the particular command.
