“…Another SVC layer-aware FEC scheme for DVB-H based on Raptor codes and UEP is proposed in [41,42], which shows an increased protection for the base layer without increased bit rate. To compensate for transmission errors in SVC over DVB-H, [43][44][45] have discussed SVC link layer FEC schemes, like MPE-FEC and MPE-iFEC, and SVC layer-aware FEC. In [44,45], the proposed layer-aware FEC with UEP and transmission scheduling achieves lower packet error rate and improved video quality.…”

Multimedia multicast/broadcast transmissions provide simultaneous access to a common service to the heterogeneous user equipments (UEs) with different device and channel characteristics. One of the major challenges to the service providers is the exponential growth of energy-constrained UEs. In this context, the optimization of multimedia multicast/broadcast transmissions that consider the constraints imposed by the UEs is a major concern of the service providers to ensure high Quality of Experience levels to the customers with diverse constraints. This paper presents an overview of the multimedia multicast/broadcast challenges and open issues, identifies the main factors and the associated constraints that impact the multimedia transmission, and provides a comprehensive classification, comparison, and analysis of the state-of-the-art user-centric, energyefficient multimedia multicast/broadcast approaches.

“…Hence the transmission power assigned to the enhancement layers was wasted. To circumvent this problem, the authors of [11], [12] proposed the so-called layeraware forward error correction (LA-FEC) philosophy relying on Raptor coded protection of the enhancement layer for transmission over the BEC. At the transmitter, the parity bits of the less important enhancement layers may also be used for protecting the base layer.…”

“…The performance of IL-FEC using a classic turbo code and a recursive systematic convolutional (RSC) code is characterized in Section IV for two video sequences of different motion activity. Finally, we offer our conclusions in Section V. Again, in layered video compression [1], [4], [12], the video is encoded into several discrete layers, which are of unequal importance and are capable of progressively refining the video resolution/quality. The most important layer is the base layer, while the remaining layers are referred to as enhancement layers.…”

Abstract-Layered video coding creates multiple layers of unequal importance, where the enhancement layers will be affected when the base layer is corrupted. In this treatise, a novel inter-layer FEC scheme is investigated, where the information of the base layer 1 is incorporated into the systematic bits of the enhancement layers with the aid of an exclusive-OR operation. When the base layer can be recovered independently, the soft information of the enhancement layers can be deduced by flipping the sign of the check information received. In this case, the protection strength of the enhancement layer is unaffected and no extra protection bits are required. Otherwise, the inter-layer FEC decoding philosophy related to the base layer and the enhancement layer will be activated to assist in decoding the base layer, where the protection of the enhancement layer is additionally exploited to protect the base layer. Data partitioning based experiments show that our proposed scheme outperforms the traditional unequal error protection FEC aided transmission system by about 1.8 dB of channel SNR or 7.7 dB of PSNR at an acceptable complexity.

SummaryForward error correction (FEC) techniques are widely used to recover packet losses over unreliable networks in real-time video streaming applications.Traditional frame-level FEC encodes 1 video frame in each FEC coding window. By contrast, in the expanding-window FEC scheme, high-priority frames are included in the FEC processing of the following frames, so as to construct a larger coding window. In general, expanding-window FEC improves the recovery performance of FEC, because the high-priority frame can be protected by multiple windows and the use of a larger coding window increases the efficiency. However, the larger window size also increases the complexity of the coding and the memory space requirements. Consequently, expanding-window FEC is limited in terms of practical applications. Sliding-window FEC adopts a fixed window size in order to approximate the performance of the expanding-window FEC method, but with a reduced complexity. Previous studies on sliding-window FEC have generally adopted an equal error protection (EEP) mechanism to simplify the analysis. This paper considers the more practical case of an unequal error protection (UEP) strategy. An analytical model is derived for estimating the playable frame rate (PFR) of the proposed sliding-window FEC scheme with a Reed-Solomon erasure code for real-time non-scalable streaming applications. The analytical model is used to determine the optimal FEC configuration which maximizes the PFR value under given transmission rate constraints. The simulation results show that the proposed sliding-window scheme achieves almost the same performance as the expanding-window scheme, but with a significantly lower computational complexity.
