JVET-AL0200 AHG18: Simulation software description [S. Ikonin, V. Khamidullin, R. Shabaev, I. Gribushin, M. Sychev, E. Alshina (Huawei)]

This contribution describes the simulation software submitted for AGH18 on ultra-low latency and packet loss resilience based on contribution JVET-AK0193. The purpose of this document is to give an introduction and help to be familiar with software. The document describes main modifications of encoder and decoder applications of VTM, entry point for network transmission emulation, and basic logic of main modules. Content of this document was mainly presented during AHG18 teleconference call on 2025-02-19. The software is available in https://vcgit.hhi.fraunhofer.de/jvet-ahg-ull/VVCSoftware_VTM/

It was commented that the software provided in the link requires an update.

It was explained that the software is running encoder and decoder separately. The encoder app has a “jitter buffer” which gets input from the network simulator and simulates the feedback to be sent from the decoder if a packet loss would occur. The decoder gets the bitstream which comes with the packet losses and subsequent repair packets.

It was commented that trace files should not be used in optimizing concealment and packetization strategies.
