    Abstract: The present disclosure relates to an adaptive audio processing method, device, computer program, and recording medium thereof in a wireless communication system. A method of transmitting audio data from a first device to a second device in a wireless communication system, according to an embodiment of the present disclosure, may comprise: encoding first audio data in the first device, on the basis of a first codec parameter, to transmit same to the second device; transmitting, from the first device to the second device, information related to a change time point or a change position from the first codec parameter to second codec parameter; and encoding second audio data, on the basis of a second codec parameter, in the first device and transmitting same to the second device.

    Abstract: The present invention relates to an intra prediction scheme among video coding techniques and, more particularly, relates to a video decoding method and apparatus for diving a block into a plurality of sub-blocks when intra prediction is performed and sequentially performing infra prediction on each of the sub-blocks. The decoding method performed by a video decoding apparatus includes determining whether to perform sub-block-based intra prediction on a current coding unit, dividing the current coding unit into a plurality of sub-blocks, performing intra prediction on each of the sub-blocks when a result of determination of whether to perform sub-block-based intra prediction has a value of “true”, and directly performing block-based intra prediction on the current coding unit without dividing the current coding unit when the result of the determination has a value of “false”.
