A hybrid IR transmission system implements at least two IR transmission protocols with a common IR transceiver. The hybrid IR transmission system includes an IR decoding circuit, a common IR transceiver and a filter circuit. The IR decoding circuit includes an IrDA module for decoding IR signals in IrDA protocol and a CIR module for decoding IR signals in CIR protocol. The common IR transceiver receives a first IR signal in either IrDA or CIR protocol. The filter circuit processes the first IR signal into a second IR signal accessible to one of the IrDA module and the CIR module for decoding.

A method for realizing virtual multi-channel by spectrum analysis is disclosed. The low-frequency-effect sound data is obtained by averaging sound data of left and right channels in the two-channel sound source and filtering the average by a first low pass filter. The central channel sound data is obtained by averaging sound data of the left and the right channels in the two-channel sound source and filtering the average by a second low pass filter. The surround right and left sound data is obtained by copying sound data of the left and the right channels in the two-channel sound source, respectively.
