Abstract: An apparatus and method for supporting bidirectional communication using unidirectional communication. The apparatus for supporting bidirectional communication using unidirectional communication includes an internal network module for performing bidirectional communication with an internal network and communicating with an external network module depending on a communication mode, the external network module for performing bidirectional communication with an external network and communicating with the internal network module depending on the communication mode, and a communication control module for controlling, of first unidirectional communication from the internal network module to the external network module and second unidirectional communication from the external network module to the internal network module, the second unidirectional communication, thus controlling a communication function corresponding to the communication mode, wherein the communication mode includes a unidirectional communication mode, a conditional bidirectional communication mode, and a bidirectional communication mode.

Abstract: Disclosed herein are a method, an apparatus, and a storage medium for image encoding/decoding using filtering. The image encoding method and the image decoding method perform classification on a classification unit of a target image, and perform filtering that uses a filter on the classification unit. A classification index of the classification unit is determined, and the classification index indicates a filter to be used for filtering on the classification unit, among multiple filters. The classification index is determined by various coding parameters, such as an encoding mode of the target block and an encoding mode of a neighboring block adjacent to the target block.
