RTP payload format

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 document describes an RTP payload format for V3C atlas sub-bitstreams. The RTP payload format for V3C video sub-bitstreams is defined by relevant IETF RFCs for the applicable video codec. The V3C RTP payload format allows for the packetization of one or more V3C atlas Network Abstraction Layer (NAL) units in an RTP packet payload as well as the fragmentation of a V3C atlas NAL unit into multiple RTP packets. The document also describes the mechanisms for grouping RTP streams of V3C component sub-bitstreams, providing a complete solution for streaming V3C-encoded content.

This memo specifies an RTP payload format for MPEG-I haptic data. A haptic media stream is composed of MPEG-I Haptic Stream (MIHS) units including a MIHS unit header and zero or more MIHS packets. The RTP payload header format allows for packetization of a MIHS unit in an RTP packet payload as well as fragmentation of a MIHS unit into multiple RTP packets. The original subtype registration for 'haptics/hmpg' (RFC 9695) did not include any required or optional parameters. This memo updates RFC 9695 and the 'haptics/hmpg' registration to add optional parameters. It also provides Session Description Protocol (SDP) usage information for the 'haptics' media type.

This document defines the RTP payload format for the streaming of a video signal encoded as a sequence of JPEG 2000 codestreams. The format allows sub-codestream latency, such that the first RTP packet for a given image can be emitted before the entire image is available to or encoded by the sender.

This specification describes an RTP payload format for the VP9 video codec. The payload format has wide applicability as it supports applications from low bitrate peer-to-peer usage to high bitrate video conferences. It includes provisions for temporal and spatial scalability.

The working group process and the authors of RTP payload formats have sometimes failed to ensure that the media types are registered in the IANA "RTP Payload Format Media Types" registry as recommended by RFC 8088. To simplify the process and rely only on the "Media Types" registry, this document closes the RTP payload- specific registry. In addition, it updates the instruction in RFC 8088 to reflect this change.

This document describes the RTP payload format of the Secure Communication Interoperability Protocol (SCIP). SCIP is an application-layer protocol that provides end-to-end session establishment, payload encryption, packetization and de-packetization of media, and reliable transport.

The intended audience is network security policymakers; network administrators, architects, and original equipment manufacturers (OEMs); procurement personnel; and government agency and commercial industry representatives.

This document describes an RTP payload format for the Essential Video Coding (EVC) standard, published as ISO/IEC International Standard 23094-1. EVC was developed by the MPEG. The RTP payload format allows for the packetization of one or more Network Abstraction Layer (NAL) units in each RTP packet payload and the fragmentation of a NAL unit into multiple RTP packets. The payload format has broad applicability in videoconferencing, Internet video streaming, and high-bitrate entertainment-quality video, among other applications.

This memo describes an RTP payload format for the Versatile Video Coding (VVC) specification, which was published as both ITU-T Recommendation H.266 and ISO/IEC International Standard 23090-3. VVC was developed by the Joint Video Experts Team (JVET). The RTP payload format allows for packetization of one or more Network Abstraction Layer (NAL) units in each RTP packet payload, as well as fragmentation of a NAL unit into multiple RTP packets. The payload format has wide applicability in videoconferencing, Internet video streaming, and high-bitrate entertainment-quality video, among other applications.

This document specifies a Real-Time Transport Protocol (RTP) payload format to be used for transporting video encoded with JPEG XS (ISO/IEC 21122). JPEG XS is a low-latency, lightweight image coding system. Compared to an uncompressed video use case, it allows higher resolutions and video frame rates while offering visually lossless quality, reduced power consumption, and encoding-decoding latency confined to a fraction of a video frame.

In this specification, we define a framework for specifying restrictions on RTP streams in the Session Description Protocol (SDP). This framework defines a new "rid" ("restriction identifier") SDP attribute to unambiguously identify the RTP streams within an RTP session and restrict the streams' payload format parameters in a codec-agnostic way beyond what is provided with the regular payload types.

This specification updates RFC 4855 to give additional guidance on choice of Format Parameter (fmtp) names and their relation to the restrictions defined by this document.

This document describes the RTP payload format for the Tactical Secure Voice Cryptographic Interoperability Specification (TSVCIS) speech coder. TSVCIS is a scalable narrowband voice coder supporting varying encoder data rates and fallbacks.

TSVCIS augmented speech data is processed in conjunction with its temporally matched Mixed Excitation Linear Prediction (MELP) 2400 speech data. The RTP packetization of TSVCIS and MELPe speech coder data is described in detail.

This memo describes a Real-time Transport Protocol (RTP) payload format for Timed Text Markup Language (TTML), an XML-based timed text format from W3C. This payload format is specifically targeted at streaming workflows using TTML.

This document defines new RTP payload formats for the Forward Error Correction (FEC) packets that are generated by the non-interleaved and interleaved parity codes from source media encapsulated in RTP. These parity codes are systematic codes (Flexible FEC, or "FLEX FEC"), where a number of FEC repair packets are generated from a set of source packets from one or more source RTP streams. These FEC repair packets are sent in a redundancy RTP stream separate from the source RTP stream(s) that carries the source packets. RTP source packets that were lost in transmission can be reconstructed using the source and repair packets that were received. The non-interleaved and interleaved parity codes that are defined in this specification offer a good protection against random and bursty packet losses, respectively, at a cost of complexity. The RTP payload formats that are defined in this document address scalability issues experienced with the earlier specifications and offer several improvements. Due to these changes, the new payload formats are not backward compatible with earlier specifications; however, endpoints that do not implement this specification can still work by simply ignoring the FEC repair packets.

This memo describes an RTP payload format for the High Quality (HQ) profile of Society of Motion Picture and Television Engineers Standard ST 2042-1, known as VC-2. This document describes the transport of HQ Profile VC-2 in RTP packets and has applications for low-complexity, high-bandwidth streaming of both lossless and lossy compressed video.

The HQ profile of VC-2 is intended for low-latency video compression (with latency potentially on the order of lines of video) at high data rates (with compression ratios on the order of 2:1 or 4:1).

This memo describes a Real-time Transport Protocol (RTP) payload format for the Society of Motion Picture and Television Engineers (SMPTE) ancillary space (ANC) data, as defined by SMPTE ST 291-1.

This memo describes an RTP payload format for the video coding standard ITU-T Recommendation H.265 and ISO/IEC International Standard 23008-2, both also known as High Efficiency Video Coding (HEVC) and developed by the Joint Collaborative Team on Video Coding (JCT-VC). The RTP payload format allows for packetization of one or more Network Abstraction Layer (NAL) units in each RTP packet payload as well as fragmentation of a NAL unit into multiple RTP packets. Furthermore, it supports transmission of an HEVC bitstream over a single stream as well as multiple RTP streams. When multiple RTP streams are used, a single transport or multiple transports may be utilized. The payload format has wide applicability in videoconferencing, Internet video streaming, and high-bitrate entertainment-quality video, among others.

This memo describes an RTP payload format for Scalable Video Coding (SVC) as defined in Annex G of ITU-T Recommendation H.264, which is technically identical to Amendment 3 of ISO/IEC International Standard 14496-10. The RTP payload format allows for packetization of one or more Network Abstraction Layer (NAL) units in each RTP packet payload, as well as fragmentation of a NAL unit in multiple RTP packets. Furthermore, it supports transmission of an SVC stream over a single as well as multiple RTP sessions. The payload format defines a new media subtype name "H264-SVC", but is still backward compatible to RFC 6184 since the base layer, when encapsulated in its own RTP stream, must use the H.264 media subtype name ("H264") and the packetization method specified in RFC 6184. The payload format has wide applicability in videoconferencing, Internet video streaming, and high-bitrate entertainment-quality video, among others. [STANDARDS-TRACK]

This memo describes an RTP Payload format for the ITU-T Recommendation H.264 video codec and the technically identical ISO/IEC International Standard 14496-10 video codec, excluding the Scalable Video Coding (SVC) extension and the Multiview Video Coding extension, for which the RTP payload formats are defined elsewhere. The RTP payload format allows for packetization of one or more Network Abstraction Layer Units (NALUs), produced by an H.264 video encoder, in each RTP payload. The payload format has wide applicability, as it supports applications from simple low bitrate conversational usage, to Internet video streaming with interleaved transmission, to high bitrate video-on-demand.

This memo updates RFC 4733 to add event codes for telephony signals used for channel-associated signalling when carried in the telephony event RTP payload. It supersedes and adds to the original assignment of event codes for this purpose in Section 3.14 of RFC 2833. As documented in Appendix A of RFC 4733, some of the RFC 2833 events have been deprecated because their specification was ambiguous, erroneous, or redundant. In fact, the degree of change from Section 3.14 of RFC 2833 is such that implementations of the present document will be fully backward compatible with RFC 2833 implementations only in the case of full ABCD-bit signalling. This document expands and improves the coverage of signalling systems compared to RFC 2833. [STANDARDS-TRACK]

This document obsoletes RFC 3119, correcting typographical errors in the "SDP usage" section and pseudo-code appendices. [STANDARDS-TRACK]

This document specifies a payload format for generic Forward Error Correction (FEC) for media data encapsulated in RTP. It is based on the exclusive-or (parity) operation. The payload format described in this document allows end systems to apply protection using various protection lengths and levels, in addition to using various protection group sizes to adapt to different media and channel characteristics. It enables complete recovery of the protected packets or partial recovery of the critical parts of the payload depending on the packet loss situation. This scheme is completely compatible with non-FEC-capable hosts, so the receivers in a multicast group that do not implement FEC can still work by simply ignoring the protection data. This specification obsoletes RFC 2733 and RFC 3009. The FEC specified in this document is not backward compatible with RFC 2733 and RFC 3009. [STANDARDS-TRACK]

This document specifies a Real-time Transport Protocol (RTP) payload format to be used for Adaptive Multi-Rate (AMR) and Adaptive Multi-Rate Wideband (AMR-WB) encoded speech signals.

Voice over IP (VoIP) applications operating over low bandwidth dial-up and wireless networks require such enhancements for efficient use of the bandwidth. [STANDARDS-TRACK]

This memo describes how to carry dual-tone multifrequency (DTMF) signalling, other tone signals, and telephony events in RTP packets. It obsoletes RFC 2833.

This memo captures and expands upon the basic framework defined in RFC 2833, but retains only the most basic event codes. It sets up an IANA registry to which other event code assignments may be added. Companion documents add event codes to this registry relating to modem, fax, text telephony, and channel-associated signalling events. The remainder of the event codes defined in RFC 2833 are conditionally reserved in case other documents revive their use.

This document provides a number of clarifications to the original document. However, it specifically differs from RFC 2833 by removing the requirement that all compliant implementations support the DTMF events. Instead, compliant implementations taking part in out-of-band negotiations of media stream content indicate what events they support. This memo adds three new procedures to the RFC 2833 framework: subdivision of long events into segments, reporting of multiple events in a single packet, and the concept and reporting of state events.
