Remote control adapter and its control method

Abstract

The invention relates to an adapter technical field, particularly a remote control adapter arranged on the motherboard of a computer or a digital TV set top box and adaptive to a remote controller, and a control method thereof. The adapter comprises a receiving circuit, and an emission circuit. The receiving circuit mainly includes an infrared receiving integrated circuit. The emission circuit includes an infrared emitting diode, and a triode. The infrared emitting diode is connected with the emitter of the triode. The collector of the triode is connected with a parallel circuit of a resistor and a polar capacitor. The substrate of the infrared receiving integrated circuit, the infrared emitting diode and the triode is connected with the serial port of a circuit main board. The control method comprises the following steps of initializing, receiving and remote-controlling module operation by using software; determining whether entering into a transmission module based on the activation signal detection condition in each step; controlling whether alarming information is displayed via the transmission module; and re-entering into a start system after security is ensured. The adaptor can be mounted on TVs, DVDs, and computers for infrared receiving and emission.

Description

technical field [0001] The invention relates to the technical field of adapters, in particular to a remote control adapter installed on a main board of a computer or a digital TV set-top box and compatible with a remote control and a control method thereof. Background technique [0002] Remote control electrical appliances such as computers and digital TV set-top boxes usually transmit and receive remote control signals through the remote controller and the adapter on the main board of the electrical appliance. In the existing remote control adapter, the adapter only passively receives the signal transmitted by the remote controller; it cannot actively transmit the signal to control related equipment; moreover, it needs to occupy a USB interface and a serial port at the same time; The adapter on the TV set-top box has defects such as poor applicability, single function, and high power consumption. Contents of the invention [0003] One of the technical problems to be solv...
