Abstract
Low-latency volumetric video transport is a key enabling technology for more immersive communication applications. This paper presents the latest release of our open-source Real-time Transport Protocol (RTP) library called uvgRTP 3.0 that has been upgraded to support Visual Volumetric Video-based Coding (V3C) transmission in Video-based Point Cloud Compression (V-PCC) and MPEG Immersive Video (MIV) formats. uvgRTP 3.0 introduces 1) the V3C atlas RTP payload format; 2) two multiplexing methods to reduce port reservations during V3C transmission; and 3) improved packet reception with multithreading. Our performance results show that uvgRTP 3.0 can encrypt and transmit V3C bitstreams at 106 Mbit/s, with CPU core utilization of 26%, and achieving a round-trip latency of 2 ms in a local area network. The support for high-speed, encrypted V3C communication with the permissive BSD-license make uvgRTP 3.0 a potential transmission library for any industrial or academic volumetric communication system.
