“…The first, second and third epochs contains 3 source packets, 3 parity packets, and 3 parity packets, respectively. Figure 8 compares the hybrid FEC/pseudo ARQ system with the FEC system (Hwang et al, 2004) for layered transmission. The policy for the hybrid FEC/ pseudo ARQ is determined by the dynamic programming (Chu et al, 2001).…”

“…The erasure correction code is able to recover up to ρ l -k lost packets for each coding block when both the source and parity packets are delivered to the receiver. A number of techniques (Chu et al, 2001;Hwang et al, 2004) can be used for searching the optimal ρl, l = 1, ... , L, minimizing the average distortion of the layered transmission system.…”

“…These parity packets are also delivered in layers to different multicast groups. After estimating the bandwidth and packet loss probability of its download link, each receiver computes the optimal allocation of the available transmission rate between the source and parity packets, and puts together the multicast groups for the optimal collection of source and channel layers ( Hwang, et al, 2004).

A novel error control algorithm for robust video transmission is presented in this paper. In the algorithm, both the source packets and parity packets are delivered in layers. Each receiver, in accordance with its available bandwidth and packet loss rate, employs the optimal policy for subscribing source layers and parity layers minimizing the average distortion of the reconstructed frames. The algorithm is able to perform fast policy adaptation for location-and time-varying network environments. The implementation of the fast adaptive algorithm is based on a novel table look-up process, in which the tables are constructed using a dynamic programming technique. Our experiments show that the algorithm is an effective alternative for video broadcast applications where the robust transmissions over the heterogeneous network environment are desired.

“…An iterative algorithm was derived for calculating a new packet-loss probability function conditioned on the past loss rates. Diverse UEP algorithms were designed in [60], [63], [64], [110] for transmitting 3D SPIHT coded images and videos over networks imposing packet-loss events, where Reed-Solomon (RS) codes were utilized as FEC codes. An UEP scheme was conceived for object-based video communications in [67] for achieving the best attainable system performance under specific bitrate and delay constraints in an error-prone network environment.…”

Abstract-Layered video coding creates multiple layers of unequal importance, which enables us to progressively refine the reconstructed video quality. When the base layer (BL) is corrupted or lost during transmission, the enhancement layers (ELs) must be dropped, regardless whether they are perfectly decoded or not, which implies that the transmission power assigned to the ELs is wasted. For the sake of combating this problem, the class of inter-layer forward error correction (IL-FEC) solutions, also referred to as layer-aware FEC (LA-FEC 1 ), has been proposed for layered video transmissions, which jointly encode the BL and the ELs, thereby protecting the BL using the ELs. This tutorial aims for inspiring further research on IL-FEC/LA-FEC techniques, with special emphasis on the family of soft-decoded bit-level IL-FEC schemes.
