  • RFC 8872: Guidelines for Using the Multiplexing Features of RTP To
    Stream: Internet Engineering Task Force (IETF) RFC: 8872 Category: Informational Published: January 2021 ISSN: 2070-1721 Authors: M. Westerlund B. Burman C. Perkins H. Alvestrand R. Even Ericsson Ericsson University of Glasgow Google RFC 8872 Guidelines for Using the Multiplexing Features of RTP to Support Multiple Media Streams Abstract The Real-time Transport Protocol (RTP) is a flexible protocol that can be used in a wide range of applications, networks, and system topologies. That flexibility makes for wide applicability but can complicate the application design process. One particular design question that has received much attention is how to support multiple media streams in RTP. This memo discusses the available options and design trade-offs, and provides guidelines on how to use the multiplexing features of RTP to support multiple media streams.

  • RFC 3016 RTP Payload Format for MPEG-4 Audio/Visual November 2000
    Network Working Group Y. Kikuchi Request for Comments: 3016 Toshiba Category: Standards Track T. Nomura NEC S. Fukunaga Oki Y. Matsui Matsushita H. Kimata NTT November 2000 RTP Payload Format for MPEG-4 Audio/Visual Streams Status of this Memo This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited. Copyright Notice Copyright (C) The Internet Society (2000). All Rights Reserved. Abstract This document describes Real-Time Transport Protocol (RTP) payload formats for carrying each of MPEG-4 Audio and MPEG-4 Visual bitstreams without using MPEG-4 Systems. For the purpose of directly mapping MPEG-4 Audio/Visual bitstreams onto RTP packets, it provides specifications for the use of RTP header fields and also specifies fragmentation rules. It also provides specifications for Multipurpose Internet Mail Extensions (MIME) type registrations and the use of Session Description Protocol (SDP). 1. Introduction The RTP payload formats described in this document specify how MPEG-4 Audio [3][5] and MPEG-4 Visual streams [2][4] are to be fragmented and mapped directly onto RTP packets. These RTP payload formats enable transport of MPEG-4 Audio/Visual streams without using the synchronization and stream management functionality of MPEG-4 Systems [6]. Such RTP payload formats will be used in systems that have intrinsic stream management Kikuchi, et al. Standards Track [Page 1] RFC 3016 RTP Payload Format for MPEG-4 Audio/Visual November 2000 functionality and thus require no such functionality from MPEG-4 Systems.

Number: +46 8 404 8188 E-mail Address: [email protected] Attachments: Working Draft 3GPP TS 26.234 V0.5.0: “PSS; Protocols and codecs” (S4-040308) 3GPP TS 26.244 V6.0.0: "PSS; 3GPP file format (3GP)" 1. Overall Description: SA4 would like to inform SA3 that it has made recent progress on DRM protection for the transparent end-to- end Packet-switched Streaming Service (PSS). The attached working draft of TS 26.234 (V0.5.0) includes our working assumption implementing DRM confidentiality protection of streamed media and an optional mechanism for integrity protection using SRTP. The attached TS 26.244 (V6.0.0) includes support for SRTP in 3GP files. Key management is handled by using OMA DRM 2.0. The current status of our specifications, implementing the working assumption, is as follows: • TS 26.234 V0.5.0 o This is the Release-6 working draft of the PSS protocols and codecs specification. SA4 will finalize the draft in August 2004 and send it to SA for approval at SA#25 in September 2004. (Other Release-6 functionality of TS 26.234 has been sent to SA for approval at SA#24 in June 2004.) o It contains the necessary extensions for DRM protection of PSS.
