draft-galanos-fecframe-rtp-reedsolomon-01 This document defines an RTP payload format for the Forward Error Correction (FEC) that uses Reed-Solomon codes. The format defined by this document enables the protection of source media encapsulated in RTP with one or more repair flows and is based on the FEC framework (described in [I-D.ietf-fecframe-framework]) and the SDP Elements for FEC Framework (described in [I-D.ietf-fecframe-sdp-elements]). The Reed-Solomon codes used in this document belong to the class of Maximum Distance Separable (MDS) codes which means they offer optimal protection against random and bursty packet losses.

This document defines a new connectivity precondition for the Session Description Protocol (SDP) precondition framework. A connectivity precondition can be used to delay session establishment or modification until media stream connectivity has been successfully verified. The method of verification may vary depending on the type of transport used for the media. For unreliable datagram transports such as UDP, verification involves probing the stream with data or control packets. For reliable connection-oriented transports such as TCP, verification can be achieved simply by successful connection establishment or by probing the connection with data or control packets, depending on the situation.

This document defines a new report block type within the framework of RTP Control Protocol (RTCP) Extended Reports (XRs). One of the initial XR report block types is the Loss Run Length Encoding (RLE) Report Block. This report conveys information regarding the individual Real-time Transport Protocol (RTP) packet receipt and loss events experienced during the RTCP interval preceding the transmission of the report. The new report, which is referred to as the Post-repair Loss RLE report, carries information regarding the packets that remain lost after all loss-repair methods are applied. By comparing the RTP packet receipts/losses before and after the loss repair is completed, one can determine the effectiveness of the lossrepair methods in an aggregated fashion. This document also defines the signaling of the Post-repair Loss RLE report in the Session Description Protocol (SDP). Status of This Memo This is an Internet Standards Track document.

RTP Payload Format for Global System for Mobile Communications Half Rate (GSM-HR) This document specifies the payload format for packetization of Global System for Mobile Communications Half Rate (GSM-HR) speech codec data into the Real-time Transport Protocol (RTP). The payload format supports transmission of multiple frames per payload and packet loss robustness methods using redundancy. Status of This Memo This is an Internet Standards Track document.

RTP Payload Format for Standard apt-X and Enhanced apt-X Codecs draft-rea-payload-rtp-aptx-02 This document specifies a scheme for packetizing Standard apt-X, or Enhanced apt-X, encoded audio data into Real-time Transport Protocol (RTP) packets. The document describes a payload format that permits transmission of multiple related audio channels in a single RTP payload, and a means of establishing Standard apt-X and Enhanced apt-X connections through the Session Description Protocol (SDP). Status of this Memo This Internet-Draft is submitted to IETF in full conformance with the provisions of BCP 78 and BCP 79.

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. This document obsoletes RFC 3016. It contains a summary of changes from RFC 3016 and discusses backward compatibility to RFC 3016. It is a necessary revision of RFC 3016 in order to correct misalignments with the 3GPP Packetswitched Streaming Service (PSS) specification regarding the RTP payload format for MPEG-4 Audio. For the purpose of directly mapping MPEG-4 Audio/Visual bitstreams onto RTP packets, this document provides specifications for the use of RTP header fields and also specifies fragmentation rules. It also provides specifications for Media Type registration and the use of the Session Description Protocol (SDP). The audio payload format described in this document has some limitations related to the signaling of audio codec parameters for the required multiplexing format. Therefore, new system designs should utilize RFC 3640, which does not have these restrictions. Nevertheless, this revision of RFC 3016 is provided to update and complete the specification and to enable interoperable implementations.

RTP Payload Format for Scalable Video Coding 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.
