It is assumed that a reception processing unit receives a broadcast program in accordance with tuning based on the user’s specification. Each wireless sensor can include sensor elements usable to monitor one or more parameters of an element of the system and a wireless signal transmitter, such as, for example, a speaker or an antenna. Bytes transferred to and from buffers, used by an IO controllers to temporarily store data while being transferred between synchronous and asynchronous devices, are counted and an error condition is forced based on the count. The processing unit is adapted to execute a software driver including program instructions adapted to extract control codes from the digital received signal, generate an authentication code, and transfer the control codes and the authentication code to the physical layer hardware unit.
