“…Virtual channels that offered different levels of reliability and statistical loss guarantee were suggested [17], and a UEP-scheme that adopted hybrid automatic repeat request (HARQ) was proposed [18].

“…Furthermore, in this previous work related to retransmission [13][14][15][16][17][18][19] an assumption was made that the same FEC code rate would apply for retransmission requested packets, or that the modulation and coding scheme (MCS) level would just be lowered, independent of the channel conditions. The contribution of our research is the following two aspects.…”

Providing high quality video on demand (VoD) streaming service over wireless networks is very challenging due to the limited capacity and error-proneness of the wireless environment. We propose a flexible forward error correction (FEC) and a fair selection scheme of scalable units that utilize a layered coding structure of H.264/SVC (scalable video coding). Three error-resilient techniques (e.g., unequal error protection, FEC, and retransmission) are adapted to minimize the total distortion of VoD streaming service. For flexible FEC, a rateless FEC code is adopted. The FEC code rates are based on the possible number of retransmission, the condition of the wireless channel and the layered coding structure of H.264/SVC for each packet. A theoretical study is performed to show how to utilize the possible number of retransmission for an adaptive FEC code rate. With fair selection, regular and retransmission-requested packets compete for resources without fixing the retry limit. Thus, excessive retransmission is prevented and the proposed scheme effectively provides capacity-limited and delay-constrained VoD streaming services. For this fair selection of scalable units, we formulate the problem using binary integer programming and propose an effective low complexity selection algorithm based on a priority index. The proposed algorithm prioritizes packets according to the priority index and the H.264/SVC structure. We show that the proposed scheme can minimize the total video distortion compared to other heuristic procedures. Other effects of the various factors are also considered for the performance of the new scheme.

“…Several works studied coding for UEP-HARQ. The works [11] and [12] proposed UEP-HARQ via RCPCCs and turbo codes, respectively. The work [13] studied the transmission of layered video and proposed an adaptive truncated HARQ scheme which is based on CCs with separate encoding of each layer via a different RCPCC, and with a type-I HARQ with maximal ratio combining.…”

This paper presents a novel type-II hybrid automatic repeat request (HARQ) transmission scheme which is based on pruned convolutional codes (CCs) and supports unequal error protection (UEP). The data to be transmitted is assumed to consist of important bits (IB) and standard bits (SB). In the proposed scheme, all the bits are first encoded using a single mother CC and transmitted over the channel. If a decoding error is detected in the IB, then retransmission of only the IB takes place using a CC, typically with a better error correction capability. Next, taking advantage of the properties of pruned CCs, the decoded IB are used to increase the decoding reliability for the SB. Numerical simulations indicate that the proposed scheme offers strong protection for the IB along with improved reliability for the remaining bits compared to other UEP schemes.
