Approach to Data Compression Based on Waveform Storage Infrared Remote Control Transmitter

Abstract

Abstract:

Abstract: Waveform storage infrared control transmitter is unrestricted from coding format and protocol type, and data compression and coding is the key issue. The pulse width is measured with IR carrier frequency 38 kHz. The high / low pulse waveform is turned into a onedimensional array of signed numbers and clustered. A fixedlength static dictionary is built through prior knowledge. The short pulses are encoded as 2bit, and the long pulses are made up of some encoded short pulses in series. Actual tests show that the data compression rate is high, and transformed infrared remote waveform can control accurately.
