The IESG has approved the following document: - 'RTP Payload Format for Visual Volumetric Video-based Coding (V3C)' (draft-ietf-avtcore-rtp-v3c-17.txt) as Proposed Standard This document is the product of the Audio/Video Transport Core Maintenance Working Group. The IESG contact persons are Gorry Fairhurst and Mike Bishop. A URL of this Internet-Draft is: https://datatracker.ietf.org/doc/draft-ietf-avtcore-rtp-v3c/ Technical Summary A visual volumetric video-based coding (V3C) [ISO.IEC.23090-5] bitstream is composed of V3C units that contain V3C atlas sub- bitstreams, V3C video sub-bitstreams, and a V3C parameter set. This memo describes an RTP payload format for V3C atlas sub-bitstreams. The RTP payload format for V3C video sub-bitstreams is defined by relevant Internet Standards for the applicable video codec. The V3C RTP payload format allows for packetization of one or more V3C atlas Network Abstraction Layer (NAL) units in an RTP packet payload as well as fragmentation of a V3C atlas NAL unit into multiple RTP packets. The memo also describes the mechanisms for grouping RTP streams of V3C component sub-bitstreams, providing a complete solution for streaming V3C encoded content. Working Group Summary The document was reviewed in two WGLCs and was updated after this and other review. Document Quality The WG is aware of two implementations of the spec.The document does not define any MIBs, YANG modules or URI types. The IANA registrations of a media type, SDP attribute and grouping are correct. The Proposed Standard status matches the type for similar documents from the working group that define new payload formats. Personnel The Document Shepherd for this document is Marius Kleidl. The Responsible Area Director is Gorry Fairhurst.
