For multimedia traffic like VBR video, knowledge of the average loss probability is not sufficient to determine the impact of loss on the perceived visual quality and on the possible ways of improving it, for example by forward error correction (FEC) and error concealment. In this paper we investigate how the packet size distribution affects the packet loss process, i.e. the probability of cons...

The Faecal Egg Count Reduction Test (FECRT) is the most widely used field-based method for estimating anthelmintic efficacy and as an indicator of the presence of anthelmintic resistant nematodes in cattle, despite never having been validated against the gold standard of controlled slaughter studies. The objectives of this study were to assess the normality of cattle faecal egg count (FEC) data...

In video streaming over multicast networks, error recovery is essential to alleviate the effect of packet loss. In this paper, we study a feedback-free recovery scheme which combines the strength of FEC (namely, a parity packet can repair any lost packet) and pseudo-ARQ (namely, incremental recovery). To account for the receiver heterogeneity, the server multicasts layered video streams for the...

Real-time applications are becoming more and more popular and important. To address the specific needs, such as data loss and transmission delay, of these applications, FEC (Forward Error Correction) techniques based on error correcting codes are widely used. The choice of codes and their parameters are crucial in determining the efficiency of FEC, in terms of loss recovery capability, bandwidt...

Experiments were carried out to investigate the effect of condensed tannins on gastrointestinal nematodes. In the first two trials (trial 1 and 2) mature and young parasite naïve sheep under artificial haemonchosis were offered a low protein diet containing varying levels of quebracho extract (QT), a model source of condensed tannins. In trial 1, thirty-five mature rams were assigned to five gr...

Application of forward error correction (FEC) in offline streaming with large buffering time dramatically improves the quality and performance of communications in challenging network conditions. However real-time streaming puts hard restrictions on the buffer size leaving FEC helpless for combating long link failures on a single path route. Multi-path routing is another method, orthogonal to b...

Forward Error Correction (FEC) is very efficient for off-line streaming with large buffering time, but real-time streaming puts hard restrictions on the buffer size making FEC inefficient for combating long link failures on single path routes. Multi-path routing, orthogonal to buffering, can however make FEC effective also for real-time streaming. For this purpose we introduce a capillary routi...

The MBONE provides an infrastructure for multicast communication on the internet based on IP. Several proposals have been made to create reliable multicast transport on top of the MBONE structure. Nearly all research on reliable multicast protocols for the MBONE focuses on ARQ error recovery. The counterpart of ARQ, FEC, does not guarantee 100% reliability but increases the reliability. The aim...
