Abstract: An objective of one embodiment of the present invention is to reduce abrupt noise derived from infrared light emitted by a light source from a data signal of infrared light received by an infrared communications receiver for use with a display device including a light source without reducing the strength of the data signal. A multiplication factor for the amplitude of abrupt noise outputted by a lamp light-receiving element disposed in the vicinity of lamps of a liquid crystal television is adjusted in order for the amplitude of abrupt noise derived from the lamps and outputted by the lamp light-receiving element to be equalized with the amplitude of abrupt noise derived from the lamps and included in a data signal outputted by a data light-receiving element. Then, the abrupt noise subjected to multiplication factor adjustment is subtracted from the data signal including the abrupt noise, so that only the data signal remains and is transmitted to the liquid crystal television.

Abstract: An objective of one embodiment of the present invention is to perform infrared communications without error by reducing abrupt noise included in a data signal when a light source of a display device is driven by PWM drive. When a control portion is provided with a drive setting signal for determining whether to drive lamps of a liquid crystal television by pulse width modulation drive or by continuous drive, the control portion sets a threshold in a register for a frequency filter portion based on the provided drive setting signal. Furthermore, upon reception of infrared light from the lamps, the threshold being set is reviewed based on an occurrence frequency for abrupt noise provided by a waveform analysis portion. Thereafter, abrupt noise included in a data signal transmitted from a cell phone is reduced by the frequency filter portion, and then the data signal is transmitted to the liquid crystal television.

Abstract: The synchronization of trunk failover between two FC-AL switches when a primary trunk failure occurs is disclosed. If primary trunk T1 should fail, S1 bypasses the cascade port and sends a MaRK (MRK) ordered set out over duplicate trunk T2 to switch S2. In response, S2 sends an acknowledgement MRK ordered set over T2 back to S1. S1 then reconfigures the switch to establish T2 as the primary trunk, and acts as a masters in the failover process and initiates LIP ordered sets which are communicated to all devices in the system to initialize them. Note that when S2 receives the MRK ordered set and acknowledges it by sending an acknowledgement MRK back to S1, it acts as a slave in the failover process and does not attempt to initiate LIPs, thereby eliminating the possibility of multiple Loop Initialization cycles and reducing the time in which data cannot be transmitted.
