Bidirectional remote control system using interrupt arbitration

Claim 1

A remote control system including a remote controller and an equipment controlled by said remote controller, wherein said remote controller comprises: a remote controller having means for selectively transmitting a first remote signal of a first data format formed sequentially by a first start code, a first data code, an inverted code of said first data code and a first stop code, and a second remote signal of a second data format formed sequentially by a second start code, a second data code, a logic code having a predetermined logic relationship to said second data code and an interrupt arbitration period; and means for responding to a priority interrupt code received in said interrupt arbitration period of a current transmission period and transmitting one of an acknowledge code and a non-acknowledge code in accordance with said priority interrupt code and contents of data to be transmitted, said equipment comprising: means for determining whether a received signal is said first remote signal or said second remote signal; and determining and performing means for determining a priority level of said priority interrupt code and performing a processing operation upon said received signal in accordance with one of said acknowledge code and said non-acknowledge code received in said interrupt arbitration period, when said received signal is said second remote signal.
