“…To this purpose, the reference video sequence V is used at the source side to estimate the distortion due to the loss of a generic frame f k . Precisely, for the frames whose loss implies the failure of the decoder, such as the I frames [18], the distortion is assumed infinite. Instead, for the frames whose loss does not imply the crash of the decoder, this estimation is carried out by evaluating the MSE and the SSIM between V and the video sequence V obtained replacing f k by f k−1 , thus applying a frame copy error concealment approach.…”

This paper investigates the influence of the video quality assessment at the medium access control (MAC) layer of an 802.11e distributed network in which the purpose is to adapt the retry limit of each video packet for maximizing the quality perceived by the end user. Moving from an existing Markov model of the 802.11e access scheme, the number of retransmissions associated to each video packet is evaluated to satisfy the distortion requirements inferred using two quality assessment measures: the mean squared error (MSE) and the structural similarity (SSIM) index. The aim of the proposed work is to discuss the suitability of these measures for managing the retransmission policy in the presence of contention-based mechanisms. The numerical results are obtained using a network simulator implementing the 802.11e enhanced distributed channel access (EDCA) in which the video sequences are encoded using the H.264 scalable video coding (SVC) standard. © 2014 IEEE

Abstract-In this paper, we address the problem of efficiently allocating network resources to support multiple scalable video streams over a constrained wireless channel. We present a resource allocation framework that jointly optimizes the operation of the link adaptation scheme in the physical layer (PHY), and that of a traffic control module in the network or medium access control (MAC) layer in multi-rate wireless networks, while satisfying bandwidth/capacity constraints. Multi-rate networks, such as IEEE 802.16 or IEEE 802.11, adjust the PHY coding and modulation schemes to maintain the reliability of transmission under varying channel conditions. Higher reliability is achieved at the cost of reduced PHY bit-rate which in turn necessitates a reduction in video stream bit-rates. The rate reduction for scalable video is implemented using a traffic control module. Conventional solutions operate unaware of the importance and loss tolerance of data and drop the higher layers of scalable video altogether. In this paper, we consider Medium Grain Scalable (MGS) extension of H.264/AVC video and develop new rate and distortion models that characterize the coded bitstream. Performance evaluations show that our proposed framework results in significant gains over existing schemes in terms of average video PSNR that can reach 3dB in some cases for different channel SNRs and different bandwidth budgets.

“…On the other hand, to provide reliable video transmission, error control is needed to combat the error-prone wireless channels, including error correction protection through joint coding [13] and tradeoff between video coding and channel coding [14] [17]. Recently, Digital Fountain code, as the famous branch in rateless codes family, has attracted significant interest in a variety of emerging wireless multimedia applications [15] [16] and standards [4].…”

Heterogeneous QoS video broadcast over wireless network is a challenging problem, where the demand for better video quality needs to be reconciled with different display size, channel condition and QoS requirements. In this paper, we present a framework for broadcasting scalable video to heterogeneous mobile users with diverse display devices and different channel conditions, which includes joint spatial-temporal layered video and Fountain coding optimization. First, we develop an elastic rate video adaptation method so as to serve mobile users with heterogeneous QoS requirements, which includes a hybrid temporal-spatial quality metric. Joint Fountain coding protection is introduced so as to provide adaptive and reliable video streams. Second, we use dynamic programming approach to obtain optimal video layer structure, so as to achieve maximum broadcasting utility. The objective is to achieve maximum overall receiving quality of the heterogeneous QoS users. Experimental results demonstrate the effectiveness of the solution.
