RTP Payload Format for MIDI (Musical Instrument Digital Interface) |
This memo describes a Real-time Transport Protocol (RTP) payload
format for the MIDI command
language. The format encodes all commands that may legally appear on
a MIDI 1.0 DIN cable. The format is suitable for interactive
applications (such as network musical performance) and content-delivery
applications (such as file streaming). The format may be
used over unicast and multicast UDP and TCP, and it defines tools for
graceful recovery from packet loss. Stream behavior, including the
MIDI rendering method, may be customized during session setup. The
format also serves as a mode for the mpeg4-generic format, to support
the MPEG 4 Audio Object Types for General MIDI, Downloadable Sounds
Level 2, and Structured Audio.
The "audio/rtp-midi" and "audio/asc" media types have been registered by the IANA, as well as
the "rtp-midi" value for the "mode" parameter of the "mpeg4-generic" media type, defined in RFC3640.

An Implementation Guide for RTP MIDI |
|
This memo offers non-normative implementation guidance for the Real-time
Protocol (RTP) MIDI (Musical Instrument Digital Interface)
payload format. The memo presents its advice in the context of a
network musical performance application. In this application two
musicians, located in different physical locations, interact over a
network to perform as they would if located in the same room.
Underlying the performances are RTP MIDI sessions over unicast UDP.
Algorithms for sending and receiving recovery journals (the
resiliency structure for the payload format) are described in detail.
Although the memo focuses on network musical performance, the
presented implementation advice is relevant to other RTP MIDI
applications.

This document describes the RTP payload format for Enhanced Variable
Rate Codec (EVRC) Speech and Selectable Mode Vocoder (SMV) Speech.
Two sub-formats are specified for different application scenarios. A
bundled/interleaved format is included to reduce the effect of packet
loss on speech quality and amortize the overhead of the RTP header
over more than one speech frame. A non-bundled format is also
supported for conversational applications.
The following media types have been registered by the IANA:

RTP Payload Format for AC-3 Audio |
This document describes an RTP payload format for transporting audio
data using the AC-3 audio compression standard. AC-3 is a high
quality, multichannel audio coding system that is used for United
States HDTV, DVD, cable television, satellite television and other
media. The RTP payload format presented in this document includes
support for data fragmentation.
AC-3 is designed to encode multiple channels of audio into a low bit-rate
format. AC-3 achieves its large compression ratios via encoding a
multiplicity of channels as a single entity. Dolby Digital, which is
a branded version of AC-3, encodes up to 5.1 channels of audio.
AC-3 has been adopted as an audio compression scheme for many
consumer and professional applications. It is a mandatory audio
codec for DVD-video, Advanced Television Standards Committee (ATSC)
digital terrestrial television and Digital Living Network Alliance
(DLNA) home networking, as well as an optional multichannel audio
format for DVD-audio.
There is a need to stream AC-3 data over IP networks. The Internet
Real Time Protocol (RTP) provides a mechanism for stream
synchronization and hence serves as the best transport solution for
AC-3, which is primarily used in audio-for-video applications.
Applications for streaming AC-3 include streaming movies from a home
media server to a display, video on demand, and multichannel Internet
radio.
The "audio/ac3" MIME media type has been registered by the IANA.

RTP Payload Format for Enhanced AC-3 (E-AC-3) Audio |
This document describes a Real-time Transport Protocol (RTP) payload
format for transporting Enhanced AC-3 (E-AC-3) encoded audio data.
E-AC-3 is a high-quality, multichannel audio coding format and is an
extension of the AC-3 audio coding format, which is used in US High-Definition
Television (HDTV), DVD, cable and satellite television,
and other media. E-AC-3 is an optional audio format in US and world
wide digital television and high-definition DVD formats. The RTP
payload format as presented in this document includes support for
data fragmentation.
The Enhanced AC-3 (E-AC-3) [ETSI TS 102 366] audio coding system is built on a
foundation of AC-3. It is an enhancement and extension to AC-3,
which is an existing audio coding standard commonly used for DVD,
broadcast, cable, and satellite television content. E-AC-3 is
designed to enable operation at both higher and lower data rates than
AC-3, provide expanded channel configurations, and provide greater
flexibility for carriage of multiple audio program elements. The
relationship between E-AC-3 and AC-3 provides for low-loss, low-cost
conversion between the two and makes E-AC-3 especially suitable in
applications that require compatibility with the existing broadcast-reception
and audio/video decoding infrastructure. Dolby Digital
Plus is a branded version of Enhanced AC-3.
E-AC-3 has been standardized within both the European
Telecommunications Standards Institute (ETSI) and the Advanced
Television Systems Committee (ATSC). It is an optional audio format
for use in US (ATSC) and Digital Video Broadcasting (DVB) television
transmission. It is also a required audio format for use in the High
Definition (HD)-DVD optical-storage media format and included in the
Blu-ray Disc format.
There is a need to stream E-AC-3 content over IP networks. E-AC-3 is
primarily used in audio-for-video applications, so RTP serves well as
a transport solution with its mechanism for synchronizing streams.
Applications for streaming E-AC-3 include Internet Protocol
television (IPTV), video on demand, interactive features of next
generation DVD formats, and transfer of movies across a home network.
The "audio/eac3" MIME media type has been registered by the IANA.

or audio flow over the transport protocols supported by RTP. Two
approaches are described. The first is designed to support maximum
interoperability with MPEG System environments. The second is
designed to provide maximum compatibility with other RTP-encapsulated
media streams and future conference control work of the IETF.
This memo is a revision of RFC 2038, an Internet standards track
protocol. In this revision, the packet loss resilience mechanisms in
Section 3.4 were extended to include additional picture header
information required for MPEG2. A new section on security
considerations for this payload type is added.

RTP Payload Format for H.264 Video |
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. 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 bit-rate conversational usage, to
Internet video streaming with interleaved transmission, to high bit-rate
video-on-demand.
The H.264 video codec has a very broad application range that covers
all forms of digital compressed video from, low bit-rate Internet
streaming applications to HDTV broadcast and Digital Cinema
applications with nearly lossless coding. Compared to the current
state of technology, the overall performance of H.264 is such that
bit rate savings of 50% or more are reported. Digital Satellite TV
quality, for example, was reported to be achievable at 1.5 Mbit/s,
compared to the current operation point of MPEG 2 video at around 3.5
Mbit/s.
The "video/H264" MIME media type has been registered by the IANA.

RTP Payload Format for BT.656 Video Encoding |
This document specifies the RTP payload format for encapsulating ITU
Recommendation BT.656-3 video streams in the Real-Time Transport
Protocol (RTP). Each RTP packet contains all or a portion of one
scan line as defined by ITU Recommendation BT.601-5, and includes
fragmentation, decoding and positioning information.
This document describes a scheme to packetize uncompressed, studio-
quality video streams as defined by BT.656 for transport using RTP.
A BT.656 video stream is defined by ITU-R Recommendation
BT.656-3, as a means of interconnecting digital television
equipment operating on the 525-line or 625-line standards, and
complying with the 4:2:2 encoding parameters as defined in ITU-R
Recommendation BT.601-5 (formerly CCIR-601), Part A.
The "video/BT656" media type has been registered in RFC3555, section 4.2.

RTP Payload Format for Uncompressed Video |
This memo specifies a packetization scheme for encapsulating
uncompressed video into a payload format for the Real-time Transport
Protocol, RTP. It supports a range of standard- and high-definition
video formats, including common television formats such as ITU
BT.601, and standards from the Society of Motion Picture and
Television Engineers (SMPTE), such as SMPTE 274M and SMPTE 296M. The
format is designed to be applicable and extensible to new video
formats as they are developed.
The "video/raw" MIME media type has been registered by the IANA.

RTP Payload Format of Sun's CellB Video Encoding |
This memo describes a packetization scheme for the CellB video
encoding. The scheme proposed allows applications to transport CellB
video flows over protocols used by RTP. This document is meant for
implementors of video applications that want to use RTP and CellB.
The Cell image compression algorithm is a variable bit-rate video
coding scheme. It provides "high" quality, low bit-rate image
compression at low computational cost. The bytestream that is
produced by the Cell encoder consists of instructional codes and
information about the compressed image.
Currently, there are two versions of the Cell compression technology:
CellA and CellB. CellA is primarily designed for the encoding of
stored video intended for local display, and will not be discussed in
this memo.
CellB, derived from CellA, has been optimized for network-based video
applications. It is computationally symmetric in both encode and
decode. CellB utilizes a fixed colormap and vector quantization
techniques in the YUV color space to achieve compression.
