Latest Patents

One of his latest patents is titled "Method and apparatus for encoding and decoding high frequency band." This invention provides a method and apparatus for encoding or decoding a signal corresponding to a high frequency band in an audio signal. The method detects and encodes frequency components according to a pre-set criterion from a signal corresponding to a frequency band higher than a pre-set frequency. It encodes energy values of a signal to reconstruct bands that include the detected frequency components. This innovation ensures that even with a small number of bits used for encoding or decoding, there is no degradation in sound quality, maximizing coding efficiency.

Another notable patent is "Method, apparatus, and medium for bandwidth extension encoding and decoding." This invention allows for the encoding and decoding of a high frequency band signal by utilizing a low frequency band signal corresponding to an audio or speech signal. By doing so, the high frequency band signal can be encoded and decoded with a smaller data size while maintaining sound quality.
