End-to-End Delivery of VVC Multicast Services over 5G Mobile Network
Résumé
This industrial demo showcases an end-to-end live video delivery chain leveraging Versatile Video Coding (VVC) and multicast-ROUTE over a 5G radio access network. The VVC encoder is provided by Ateme, achieving live encoding of a complete OTT ladder, from SD to 4K, packaged into CMAF using low-latency chunks, published on a local origin server. The multicast server, deployed prior to the base-station, is provided by GPAC and is performing ROUTE encapsulation of the CMAF services pushed by the encoder on the origin server. The multicast bitstreams are ingested by an Amarisoft Callbox providing 4G-Lte and 5G-NR core network and Radio Access Network (RAN) enabling to deliver LTE-Broadcast or unicast services to the smartphones. The playback of the services is achieved on a 5G smartphone running both a multicast client and a VVC-compatible player, in an interactive manner (dynamic quality selection). The multicast client is provided by GPAC and the VVC decoding library is Fraunhofer HHI VVdeC, optimized for ARM. The demonstration is highlighting how these emerging technologies can be deployed together to enable next-generation video services over 5G mobile network.
