RTP Payload Format for Tactical Secure Voice Cryptographic Interoperability Specification Codec
RFC 8817, “RTP Payload Format for Tactical Secure Voice Cryptographic Interoperability Specification Codec”, is a Proposed Standard document published in August 2020 by V. Demjanenko, J. Punaro, D. Satterlee. The canonical text is published by the RFC Editor.
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 Mixed Excitation Linear Prediction Enhanced (MELPe) speech coder by conveying additional speech coder parameters to enhance voice quality. 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.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
