Steganographic Packet Loss Concealment for Wireless VoIP
We propose a method for the concealment of frame erasures in packet switched speech communication systems such as Voice over IP that is particularly tailored to the case of wireless transmission. At the receiver, the concealment algorithm is assisted by specific side information that is communicated via a steganographic channel within the bitstream of the employed speech codec. An exemplary imp...
متن کاملImproved Packet Loss Concealment for Pcm Voip
Voice-over-IP (VoIP), the transmission of packetized voice over IP networks, is gaining much attention as a possible alternative to conventional public switched telephone networks (PSTN). However, impairments present on IP networks, namely jitter, delay and channel errors can lead to the loss of packets at the receiving end. This packet loss degrades the speech quality. Model-based speech coder...
متن کاملPacket Loss Concealment Algorithm for VoIP Transmission in Unreliable Networks
In this paper the authors propose an algorithm for packet loss concealment (PLC) in transmission over IP-based networks with high packet loss rate. The algorithm is a sender-receiver-based extension of ANSI T1.521a Annex B PLC standard for G.711 voice codec. It consists in adding to a transmitted packet redundant parameters describing speech signal in another packet. Efficiency of the proposed ...
متن کاملEfficient Packet Loss Concealment for Narrowband Wireless VoIP System
Internet Protocol is used as a communication platform for Voice over Internet Protocol (VoIP). Before the transmission of VoIP it is required to do signal processing for reliable & efficient performance over the computer and the communication platform.Speech quality is critically important to update the service. Signal quality gets deteriorated at network layer due to problems like delay, jitte...
متن کاملA Packet Loss Concealment Technique for VoIP using Steganography
Speech quality of VoIP (Voice over Internet Protocol) may potentially be degraded by transmission errors such as packet loss and delay that are basically inevitable in best-effort communications. This study newly proposes an error concealment technique for such degradation by taking account of both sender-based and receiver-based procedure. In the proposed technique, sender-based side informati...
