Burst Loss Resilient Packetization of Video
2010 IEEE International Conference on Communications, 2010In video transmission over packet-based networks, packet losses often occur in bursts. In this paper, we present a novel packetization method for increasing the robustness of compressed video against bursty packet losses. The proposed method is based on creating a coding order of macroblocks (MBs) so that the blocks that are close to each other in the ...

Piggyback Packetization of Duplicate Packets for Packet-Loss Resilient Video Transmission
IEICE Transactions on Communications, 2006The transmission of duplicate packets provides a loss-resilience without undue time-delay in the video transmission over packet loss networks. However, this method generally deteriorates the problem of traffic congestion because of the increased bit-rate for duplicate packet transmission.

Adaptive packet parity coding for loss-packet recovery
2009 IEEE Pacific Rim Conference on Communications, Computers and Signal Processing, 2009An adaptive packet parity coding is proposed for recovering the loss packets over packet loss network links. For every (n-1) packets of data, this coding scheme transmits an error-correcting packet that contains the XOR of the previous (n-1) packets of data.

Transmission over real-world networks will occasionally suffer from transmission errors, which can significantly deteriorate the perceived quality of a speech codec. This chapter addresses the problem of transmission errors in packet based voice applications, such as voice over Internet protocol (VoIP).

This work compares the performance of three compensation methods for speech recognition in the presence of packet loss. Two methods, cubic interpolation and a novel maximum a posteriori (MAP) estimation, aim to restore the feature vector stream in the event of packet loss, while the third technique applies compensation in the decoding stage of ...

WaveNetEQ — Packet Loss Concealment with WaveRNN
2020 54th Asilomar Conference on Signals, Systems, and Computers, 2020We present WaveNetEQ, a novel packet loss concealment method based on a WaveRNN architecture. The model is conditioned on a log-mel spectrogram of the past signal to extract slow moving features, like voice characteristics and prosody and achieves significantly better quality than pattern based methods for medium and long term packet loss.

Empirical study of inter-arrival packet times and packet losses
Proceedings 22nd International Conference on Distributed Computing Systems Workshops, 2003A packet switched network such as the Internet provides only the best-effort service for users. Recent studies of the characteristics of packet arrival on a packet switched network have shown a self-similar property with long-range dependence, and also show a heavy-tailed distribution.

Study of packet loss in a packet switched voice system
IEEE International Conference on Communications, - Spanning the Universe., 2003A study is presented of the temporal behavior of packet loss on a voice-transmitted TDM time-division multiplexed link. The mean duration is given of blocking and nonblocking periods, the variance of blocking periods, and the expected packet. The loss rate within blocking periods is derived.

A survey on VoIP packet loss techniques
International Journal of Communication Networks and Distributed Systems, 2015Voice over internet protocol (VoIP) is a group of hardware and software that facilitates people to utilise the internet as the transmission medium for telephone calls by transmitting voice data in packets using IP instead of using conventional circuit transmissions of the public switched telephone network (PSTN).
