abstract = "With the advancement of metaverse and virtual reality (VR) content technologies, the demand for point cloud technology that precisely reproduces the real world is increasing. However, due to the large data size, real-time transmission requires high bandwidth, which poses challenges for interaction-based applications. This study builds a WebRTC-based real-time transmission system and compares the performance of three methods— RDP, Protobuf, and Draco—in terms of encoding time, transmission delay, decoding time, received FPS, and data size. Experimental results show that RDP achieved fast encoding and decoding speeds, Protobuf provided balanced performance, and Draco achieved high compression efficiency and low transmission delay. Each method exhibits different characteristics, confirming that a balanced choice between transmission efficiency and real-time performance is essential for point cloud transmission."
