“…The video encoder used to split the video into multiple descriptions follows the model proposed in [7]. This model starts performing a temporal motion compensated wavelet transform and then a multiple description bit allocation as presented respectively in [9] and [10].…”

“…The redundancy parameter tune the redundancy between the descriptions based on current channel characteristics. Finally, with the bit rates produced in the bit allocation module the coder produces JPEG 2000 compatible code-streams provided with error detection capabilities [7]. The error detection capabilities of the modified JPEG 2000 allows to perform central decoding that uses all possible information from the description arriving to the decoder, even if some of them present errors due to communication using unreliable channels.…”

“…In this paper, we investigate the use of a new multiple description video encoder called REGPROT [7] for P2P real time video streaming. It is shown experimentally that varying the redundancy level of each description on the fly is indeed effective for P2P media streaming using the REGPROT multiple description video encoder.…”

Peer-to-peer media streaming is a very attractive approach since the bandwidth available to serve content scales with demand. A challenge key, however, is making content distribution robust to peer transience. Multiple description coding (MDC) has proven to be very effective in problems related to packet loss, since it generates several descriptions that allow the reconstruction of the original information with any number of descriptions that can reach the decoder. In this way, multiple description may be effective for robust peer-to-peer streaming. This paper investigates the influence of MDC on the robustness of peer-to-peer video streaming. It is shown that not only MDC can really be effective for robust peer-to-peer video streaming, but also that varying the redundancy level of description on the fly lead to a better performance regarding an existent system where this parameter is fix.
