—Most of multipath multimedia streaming proposals use Forward Error Correction (FEC) approach to protect from packet losses. However, FEC does not sustain well burst of losses even when packets from a given FEC block are spread over multiple paths. In this article, we propose an online multipath convolutional coding for real-time multipath streaming based(More)
—Video transmission is sensitive to losses due to high compression efficiency. To tolerate the quality degradation from losses, Forward Error Correction (FEC) and error resilience schemes are commonly used. In this paper, we evaluate the performance of error tolerance schemes with the latest video coding standard, H.264/AVC. The analysis in three zones of(More)
—In networks with very large delay like satellite IP-based networks, standard TCP is unable to correctly grab the available resources. To overcome this problem, Performance Enhancing Proxies (PEPs), which break the end-to-end connection and simulate a receiver close enough to the sender, can be placed before the links with large delay. Although splitting(More)
—This paper introduces a redundancy adaptation algorithm for an on-the-fly erasure network coding scheme called Tetrys in the context of real-time video transmission. The algorithm exploits the relationship between the redundancy ratio used by Tetrys and the gain or loss in encoding bit rate from changing a video quality parameter called the Quantization(More)
This paper proposes "LD-Tetrys" (Late Decoding Tetrys), a solution based on an on-the-fly erasure code that attempts to solve the problem of late decoded packets usually considered as lost by the video decoder. LD-Tetrys has the following advantages: <i>i)</i> it drastically improves the trade-off between throughput and quality without modifying the codecs(More)
(2015) Enabling E2E reliable communications with adaptive re-encoding over delay tolerant networks. OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. Abstract—End-to-end (E2E) reliable communication in Delay Tolerant Network (DTN) is a challenging task due to long(More)
OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. Abstract—Following the constant increase of the multimedia traffic, it seems necessary to allow transport protocols to be aware of the video quality of the transmitted flows rather than the throughput. This paper(More)
The use of real-time applications over the Internet is a challenging problem that the QoS epoch attempted to solve by proposing the DiffServ architecture. Today, the only existing service provided by the Internet is still best-effort. As a result, multimedia applications often perform on top of a transport layer that provides a variable sending rate. In an(More)
An IP-ERN architecture to enable hybrid E2E/ERN protocol and application to satellite networking. OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. Abstract We propose an architecture based on a hybrid E2E-ERN approach allowing ERN protocols to be inter-operable with(More)
