Fault-tolerance of capillary multi-path routing for real-time multimedia streaming with forward error correction

Using forward error correction (FEC) in off-line streaming, permitting large buffers, yields spectacular results, but real-time streaming puts hard restrictions on the buffer size and therefore does not allow FEC to deal with long link failures on a single ...

Index Assignment for N Balanced Multiple Description Scalar Quantization

Pascal Frossard, Ivana Radulovic

In this paper, we address the design of any number of balanced multiple descriptions using the multiple description scalar quantization(MDSQ) technique. The proposed scheme has the advantages of low complexity, the possibility of being extended easily to a ...

Transmission of Images over Noisy Channels Using Error-resilient Wavelet Coding and Forward Error Correction

Nikolaos Thomos

A novel embedded wavelet coding scheme is proposed for the transmission of images over unreliable channels. The proposed scheme is based on the partitioning of information into a number of layers which can be decoded independently provided that some import ...

Adaptive Joint Playout Buffer and FEC Adjustment for Internet Telephony

Jean-Yves Le Boudec, Catherine Boutremans

We develop a joint playout buffer and Forward Error Correction (FEC) adjustment scheme for Internet Telephony, which incorporates the impact of end-to-end delay on the perceived audio quality. We show that it provides better quality than the adjustment sch ...

Adaptive joint playout buffer and FEC adjustement for Internet Telephony

Jean-Yves Le Boudec, Catherine Boutremans

We develop a joint playout buffer and Forward Error Correction (FEC) adjustment scheme for Internet Telephony that incorporates the impact of end-to-end delay on the perceived audio quality. We show that it provides a better quality than the adjustment sch ...

Improved low-density parity-check codes using irregular graphs

Mohammad Amin Shokrollahi

We construct new families of error-correcting codes based on Gallager's (1973) low-density parity-check codes. We improve on Gallager's results by introducing irregular parity-check matrices and a new rigorous analysis of hard-decision decoding of these co ...

Joint Source/FEC Rate Selection for Quality-Optimal MPEG-2 Video Delivery

Pascal Frossard

This paper deals with the optimal allocation of MPEG-2 encoding and media-independent Forward Error Correction (FEC) rates under a total given bandwidth. The optimality is defined in terms of minimum perceptual end-to-end distortion given a set of video an ...

Realisation of an Adaptive Audio Tool

Catherine Boutremans, Arnaud Meylan

Real-time audio over the best effort Internet often suffers from packet loss. So far, Forward Error Correction (FEC) seems to be an efficient way to attenuate the impact of loss. Nevertheless to ensure efficiency of FEC, the source rate must be continuousl ...
