Latest Patents
Among his latest patents, Akio Jin has developed a method, apparatus, and program for encoding digital signals, as well as a corresponding method, apparatus, and program for decoding digital signals. His innovative approach involves a down sampler that reduces the sampling frequency of a digital signal from 96 kHz to 48 kHz on a frame-by-frame basis. The converted signal is then compression encoded and output as a main code Im. An up sampler is utilized to convert a partial signal corresponding to the main code Im back to the original sampling frequency of 96 kHz. An error signal is generated between the up sampled signal and the input digital signal, which is then processed to produce an error code Pe. This process ensures high fidelity in the reproduced signal, whether based on the main code Im alone or in conjunction with the error code Pe.
