Abstract: Provided is a method of transmitting an anisochronous packet between devices in a time-sensitive wireless network. The method includes determining whether a whole packet to be transmitted is transmittable within a residual time of a contention period (CP), when the whole packet to be transmitted is not transmittable within the residual time of the CP, segmenting the packet to be transmitted into packet fragments with a length which is transmittable within the residual time of the CP, adding packet fragment information to the packet fragments, and transmitting one of the packet fragments within the residual time of the CP.

Abstract: The present invention relates to image processing, and more particularly, to a video coding/decoding method using a clipped motion vector and an apparatus thereof. An embodiment of the present invention relates to a method of decoding an image. The method includes clipping a motion vector of a reference picture in a predetermined dynamic range to generate a clipped motion vector, storing the clipped motion vector in a buffer, deriving a motion vector of a coding treeblock using the motion vector stored in the buffer, and performing inter prediction decoding process using the motion vector of the coding treeblock. According to the exemplary embodiment of the present invention, a size of a memory required for storing motion vectors may be reduced.
