“…While the first version of HEVC standard provides temporal scalability, the SHVC provides spatial, signal-to-noise ratio, bit depth, and color gamut scalability functionalities, as well as various combinations of any of these [28] [49]. The SHVC test model (SHM 10) document and the latest reference software (SHM 12) can be found in [50] and [51], respectively. The common conditions under which the performance of SHVC is tested can be found in [52].…”

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.

A hybrid estimate model for transmission distortions is proposed by analyzing characteristics of error propagation in multiview video coding (MVC) in this paper. Based on this model, a joint source-channel RDO mode selection algorithm is proposed, which combines the transmission distortion estimation model with traditional RDO to select out the optimal mode to decrease the distortion of decoded pictures. Both proposed model and algorithm are demonstrated via simulation results for video transmission over packet loss channel. The transmission distortions can be estimated quickly and accurately by proposed model. Compared with RDO in JMVC, joint source-channel RDO mode selection algorithm can improve the quality of decoded pictures 1.38 dB in average when the video streams are transmitted through error-prone channels.
