Residual packet loss rate analysis of 2-D parity forward error correction

“…Thus, all the lost packets in the matrix M can be recovered iteratively. Now, if G M is not a bipartite tree (or a forest of bipartite trees), it must then have a cycle of even length 2 . Let (r i 1 , c j 1 , r i 2 , c j 2 , • • • , r i l , c j l , r i 1 ) be such a cycle of minimal length, which implies that r i s r i t and c i s c i t , ∀s t. This is a subset of l rows and l columns with at least two losses in each of them.…”

“…During the last decade or so, video services have started migrating from circuit-switched (e.g. point-to-point coax) to packet-switched networks in both wireline and wireless infrastructures [1,2]. This ongoing transition to IP systems enables broadcasters and service providers to reduce their costs, and use their networks more efficiently [3][4][5].…”

QoS Routing for Multimedia Communication over Wireless Mobile Ad Hoc Networks

“…The diverse nature of networked multimedia applications causes various problems because each application has its own requirements (Rao et al, 2002). An application might demand better quality data and can tolerate some acceptable amount of delay, while another application may be more sensitive to delay by compromising the quality of data.…”

“…Multimedia applications can be categorized as per their delay requirements (Rao et al, 2002). Non real-time applications (e.g.…”

“…An interactive application requires two-way traffic, each of which is very much delay sensitive. In interactive applications, one single path may lead to network congestion ultimately affecting the overall network throughput and especially QoS (Rao et al, 2002).…”
