Abstract 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...
Programme production using a managed Internet Protocol (IP) network makes use of technologies from various areas such as media transport, signalling, synchronization, and codecs. This Recommendation provides guidance on choosing technologies applicable to real-time programme production using...
Abstract 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. It is implemented as an augmentation to the...
Globally considered as one of the key technologies in the field of wireless communications, cognitive radio has the capability to solve the issues related to radio spectrum scarcity with the help of dynamic spectrum allocation. It discusses topics including software defined radio architecture,...
This Recommendation specifies 25 Gbit/s and 50 Gbit/s optical transport network (OTN) short-reach interfaces with Reed-Solomon forward error correction codes (OTU25-RS, OTU50-RS) with lower overhead percentage than the Reed-Solomon forward error correction (FEC) code specified for OTUk (k=1,2,3,4)...
This Recommendation specifies 25 Gbit/s and 50 Gbit/s optical transport network (OTN) short-reach interfaces with Reed-Solomon forward error correction codes (OTU25-RS, OTU50-RS) with lower overhead percentage than the Reed-Solomon forward error correction (FEC) code specified for OTUk (k=1,2,3,4)...
The present document specifies the tests applicable to all Digital Enhanced Cordless Telecommunications (DECT) equipment accessing any DECT frequency band (including applicable IMT-2000 frequency bands) and the tests applicable to DECT speech and audio transmission using any of the codecs...
This Recommendation describes a set of objective video quality assessment modules that together with audio and integration modules can be used to form a complete model to predict the impact of audio and video media encodings and observed Internet protocol (IP) network impairments on quality...
This Recommendation defines user requirements for codecs that should be applied for the specifications, design and testing of systems for the secondary distribution and emission of SDTV, HDTV, UHDTV and HDR-TV signals.
Starting with essential maths, fundamentals of signals and systems, and classical concepts of DSP, this book presents, from an application-oriented
This document addresses minor issues that were found in the specification of the Opus audio codec in RFC 6716. It updates the normative decoder implementation included in Appendix A of RFC 6716. The changes fix real and potential security-related issues, as well as minor quality-related...
This document specifies MPEG media transport (MMT) technologies, which include a single encapsulation format, delivery protocols and signalling messages for transport and delivery of multimedia data over heterogeneous packet-switched networks for multimedia services. Types of packet-switched...
This document defines an extension to the Opus audio codec to encapsulate coded Ambisonics using the Ogg format. It also contains updates to RFC 7845 to reflect necessary changes in the description of channel mapping families.
This service definition is compliant with [1]. It defines a service type referred to herein as the MediaManagement service. The MediaManagement service enables the feature to set-up a media session on a Telephony Client (TC), under the control of a Telephony Control Point (TelCP). This service...
Speech and audio processing has undergone a revolution in preceding decades that has accelerated in the last few years generating game-changing technologies such as truly successful speech recognition systems; a goal that had remained out of reach until very recently. This book gives the reader a...
This document defines the methods and general principles capable of describing codec configurations in the reconfigurable video coding (RVC) framework. It primarily addresses reconfigurable video aspects and will only focus on the description of representation for video codec...
This annex1 specifies the digital test sequences for the adaptive multi-rate wideband (AMR-WB) speech codec specified in Rec. ITU-T G.722.2, its Annexes A and B, and its Appendix I. These sequences test for a bit-exact implementation of the adaptive multi-rate wideband speech transcoder,...
This document collects important information with the goal of elaborating a system layer for JPEG standards, referred to as JPEG systems. This document summarizes the principles of incremental codestream and file transport that are intended to form the future building blocks JPEG systems....
This document specifies an Application of the IMF framework specified in SMPTE ST 2067-2. The Application follows the Image Characteristics, Track File and Composition constraints specified in SMPTE ST 2067-21 whenever possible, and uses the Apple ProRes codec specified in SMPTE RDD 36.
This document outlines the audio codec and processing requirements for WebRTC endpoints.
