Abstract: A video encoding method includes: based on at least one of first distortion aware information about a current encoding unit and second distortion aware information about a corresponding reference encoding unit, determining a first predicted value of the current encoding unit using at least one interpolation filter, wherein the at least one type of interpolation filter may include an artificial intelligence (AI) interpolation filter; and encoding the current encoding unit based on the first predicted value of the current encoding unit.

Abstract: Apparatuses and methods of transmitting and receiving a speech signal. The method of transmitting a speech signal includes extracting low frequency feature information from an input speech signal by using a first feature extracting network; and transmitting a speech signal corresponding to the low frequency feature information to a receiving end. The method of receiving a speech signal includes receiving a first speech signal transmitted by a transmitting end; extracting low frequency feature information from the first speech signal and recovering high frequency feature information based on the low frequency feature information, by using a second feature extracting network; and outputting a second speech signal including the low frequency feature information and the high frequency feature information.
