Abstract: An image encoding method using a Binary Partition Tree (BPT) includes performing the BPT on a reference frame, detecting blocks, each having a difference in a pixel value exceeding a threshold value in a current frame, based on a result of the BPT of the reference frame, and performing the BPT of the current frame on the detected blocks. In accordance with the present invention, block partition is not applied to all frames, but a partial partition method based on a difference between the pixel values of a reference frame and a current frame to be encoded is provided. Accordingly, the encoding speed within the P frame or the B frame can be improved. Furthermore, the PSNR of a corresponding frame can be maintained within a specific range of the PSNR of a reference frame, and a compression effect can be improved.

Abstract: Disclosed herein are a metaverse client terminal and method for providing a metaverse space capable of enabling interaction between users. The metaverse client terminal includes a sensing data collection unit, a motion state determination unit, a server interface unit, and a metaverse space provision unit. The sensing data collection unit collects sensing data regarding a motion of a first user. The motion state determination unit determines a motion state of the first user, and generates state information data of the first user. The server interface unit transmits the state information data of the first user to a metaverse server, and receives metaverse information data and state information data of a second user. The metaverse space provision unit generates a metaverse space, generates a first avatar and a second avatar, incorporates the first and second avatars into the metaverse space, and provides the metaverse to the first user.
