This document specifies how a stereoscopic 3D High Definition ("HDTV") video contribution system based on the MPEG-2 Transport Stream (TS) performs coding, multiplexing, and decoding. It defines constraints for the input image pair, the bitstream, the multiplexing, timing synchronization,...
Preface This document gives a description of the Nokia/JSH speech and channel codec for the TIA IS-641 Enhanced Full Rate Codec. The codec consists of a 7.4 kbit/s ACELP speech codec and a 5.6 kbit/s channel codec (Forward Error Correction). Section 1 gives a...
Introduction The evaluation of digital transmission equipment for video such as codecs, can best be performed on a subjective basis, due to the complex and .adaptive natures of the multi-dimension impairments introduced by bit-rate reduction. CCIR Texts such as Recommendation 500, and...
The scope of this technical report is to provide common simulation conditions to enable repeatable evaluations of source coding and RTP packetization options. It is possible to perform cross verifications. The document includes Common source material (e.g., video clips) Pointers to...
This document specifies a Real-time Transport Protocol (RTP) payload format to be used for the International Telecommunication Union (ITU-T) G.729.1 audio codec. A media type registration is included for this payload format.
This document defines the Real-time Transport Protocol (RTP) payload format for packetization of Opus-encoded speech and audio data necessary to integrate the codec in the most compatible way. It also provides an applicability statement for the use of Opus over RTP. Further, it describes...
This memo outlines how RTP sessions are synchronised, and discusses how rapidly such synchronisation can occur. We show that most RTP sessions can be synchronised immediately, but that the use of video switching multipoint conference units (MCUs) or large source-specific multicast (SSM)...
This document describes how Dolby® E audio codecs can be used in conjunction with Television signals operating at frame rates higher than 30 Hz. Because the Dolby E encoded audio data is normally carried in an AES3 stream, wrapped per SMPTE ST 337, it may be transported separately, or...
This document specifies a Real-time Transport Protocol (RTP) payload format for Extended Adaptive Multi-Rate Wideband (AMR-WB+) encoded audio signals. The AMR-WB+ codec is an audio extension of the AMR-WB speech codec. It encompasses the AMR-WB frame types and a number of new frame...
This document updates RFC 5104 by fixing a shortcoming in the specification language of the Codec Control Message Full Intra Request (FIR) description when using it with layered codecs. In particular, a decoder refresh point needs to be sent by a media sender when a FIR is received on...
Leading-edge VoIP technologies, tools, and standards. Efficiently deliver voice, data, and multimedia content over today's always-on broadband networks with guidance from this fully updated resource. Carrier-Grade VoIP, Third Edition, shows how to set up and administer a highly reliable, unified...
This RRNR-TV (reduced reference and no reference objective models for standard definition television) test addresses two video formats (525-line and 625-line). Reduced reference (RR) models have limited bandwidth access to the source video. For an RR model to operate correctly, the...
This part of ISO/IEC 14496 specifies descriptions of the main video coding tools in hardware description language (HDL) form. Such alternative descriptions to the ones that are reported in ISO/IEC 14496-2, ISO/IEC 14496-5 and ISO/IEC TR 14496-7 correspond to the need of providing the public...
This part of ISO/IEC 14496 specifies descriptions of the main video coding tools in hardware description language (HDL) form. Such alternative descriptions to the ones that are reported in ISO/IEC 14496-2, ISO/IEC 14496-5 and ISO/IEC TR 14496-7 correspond to the need of providing the public...
This document specifies the procedures to test implementations of EVRC-A, EVRC-B, EVRC-WB, EVRC-NW or EVRC-NW2K compatible variable-rate speech codecs either by meeting the bit-exact implementation, or meeting recommended minimum performance requirements. The EVRC-A is the Service Option 3...
Scope and object This International Standard specifies both Standard Definition and High Definition receivers for the DVB-T system. It concerns: • broadcasters, and • receiver manufacturers. The objective is to define: • how to provide broadcasts that are understood by all receivers and enable...
This document specifies Real-time Transport Protocol (RTP) payload formats to be used for the Enhanced Variable Rate Narrowband-Wideband Codec (EVRC-NW). Three media type registrations are included for EVRC-NW RTP payload formats. In addition, a file format is specified for transport of...
This document describes the RTP payload format of a mU-law EMbedded Coder for Low-delay IP communication (UEMCLIP), an enhanced speech codec of ITU-T G.711. The bitstream has a scalable structure with an embedded u-law bitstream, also known as PCMU, thus providing a handy transcoding...
This document specifies a real-time transport protocol (RTP) payload format to be used for the Variable-Rate Multimode Wideband (VMR-WB) speech codec. The payload format is designed to be able to interoperate with existing VMR-WB transport formats on non-IP networks. A media type...
