Loss Concealment for Low -Bit -Rate Packet Voice
… can adapt its number of descriptions to network-loss conditions dynamically. We have compared three linear predictor representations, Reflection Coefficient, Log Area Ratio, and Line Spectral Pair (LSP), by their reconstruction qualities, and have found that the LSP representation performs the …

Multimedia data dissemination in opportunistic systems
… missing data parts in a composite ``backward'' loss concealment mechanism. So, the receiver asks first for the missing data from other nodes in the network in the form of request-response. Then, since the transmission is concerned with video content, video frame loss error concealment techniques …

The Design of A Multi-party VoIP Conferencing System
… may cause unbalanced silence periods, and losses and jitters may affect the intelligibility of speech segments received. We collect real Internet traces from the PlanetLab and classify them into different categories according to the traffic behavior. After studying the conversational …

Real-Time and High-Quality Musical Audio Streaming Over IP
… to systematically evaluate and compare Packet Loss Concealment (PLC) algorithms, which are crucial for maintaining audio quality under inevitable network losses, especially considering the unique challenges posed by musical signals. The fundamental objective of this thesis is to address these …

Design and evaluation of real-time Voice-Over-IP (VOIP) systems with high perceptual conversational quality
… for network control, playout scheduling, and loss concealment. The perceptual quality of a conversation over a network connection depends on the quality of the one-way speech (listening-only speech quality or LOSQ) received and the delay incurred from the mouth of the speaker to the ear of the …
