Abstract-Today the new technology concept, called "Internet of Things" (IoT), presents a significant field of research, due to the fact that it promises many advantages to the users worldwide. Besides this, multimedia file streaming tends to be a daily user habit, as a result of the evolution of the internet and the capabilities of devices, such as mobile phones and computers. This tendency has established Cloud Computing (CC) as a vital technology due to the fact that it reduces economic costs, improves accessibility and flexibility, while it increases the total network performance too. This paper demonstrates a new technological approach for IoT architecture, where a layered implementation with the use of many cloud servers can offer optimized streaming and download, because of the significant reduction of the transfer time costs and the storage space of the Main Cloud Server (MCS). Moreover, users will have the ability to choose or adapt to their devices' restrictions, between low -up toUltra-High Definition (UHD) quality for multimedia access and downloading, thanks to a new quality scalability feature which is introduced and is based on the new High-Efficiency Video Coding (HEVC) compression standard. Experimental results show the efficiency of the proposed approach with math formulas and graphs.

“…In recent years, cross-layer operation aided scalable video streaming designed for error-prone channels was investigated in [87], where the RS coded UEP was optimized for robust video delivery. The expected video quality was evaluated based on both the available bandwidth and the packet loss ratio (PLR) encountered, which was then further improved by employing content-aware bitrate allocation.…”

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.

“…As a further advance, unequal error protection based turbo coded modulation was investigated in [9] and both the channel capacity as well as the cutoff rates of the different protection levels were determined. Cross-layer operation aided SVC coded video streaming was proposed in [10], which ensures robust delivery of scalable video over error-prone channels. More specifically, the transmitter estimated the total distortion of the reconstructed video frame conditioned on both the bandwidth, as well as on the packet loss ratio (PLR), and invoked a powerful error concealment method.…”

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.
