			<link><![CDATA[http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6480797]]></link>
			<description><![CDATA[In this paper, we present the experimental results with analysis for subjective quality assessment on 4K-ultra-high definition (UHD) video encoded by high efficiency video coding (HEVC) to investigate its feasibility for 4K-UHD TV broadcasting services. The subjective quality assessment on the HEVC-encoded (impaired) 4K-UHD video is conducted for the three target bitrates of 18, 23, and 36 Mb/s, the two color formats of YUV420 and YUV444, and the two viewing distances of 0.75 times the height of a display screen (H) and 1.5 H. The subjective quality assessment experiments on 4K-UHD test sequences show that the HEVC-encoded (impaired) YUV420 4K-UHD video even at the target bit of 18 Mb/s yields perceptual similar visual quality: 1) with MOS of 4.7 and 4.8 in 0.75 H and 1.5 H viewing distances, respectively, compared to the original YUV420 4K-UHD test video; and 2) with MOS of 4.8 in 1.5 H viewing distance, compared to the original YUV444 4K-UHD test video. This implies that the HEVC-encoded YUV420 4K-UHD video at the target bit rate of 18 Mb/s is perceptually good enough in the usage of legacy DTV broadcasting systems with single channel bandwidths of 6 MHz. It is also shown that the HEVC-encoded 4K-UHD test sequences mostly yield higher perceptual quality in the 420 YUV color format than in the YUV444 color format at the same target bitrates.]]></description>

			<title><![CDATA[Toward Deployable Methods for Assessment of Quality for Scalable IPTV Services]]></title>
			<link><![CDATA[http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6509927]]></link>
			<description><![CDATA[Scalable video coding (H.264 SVC) is an attractive option for video service providers due to its ability to adapt a video's bitstream at the server to suit different network conditions and device characteristics. Lowering a video's bitrate can be achieved through reductions in frame rate, spatial resolution, and/or by increasing the quantization levels applied to the video sequence. In this paper, we first evaluate the effects of such scalability using some full-reference and no-reference video quality metrics, namely PSNR, SSIM, blocking, and blurring. No-reference metrics have the ability to capture the degradation in video quality caused by employing scalability in one or more dimensions. We study if conclusions drawn in previous works, which are based on well-known test video content, hold true for real-world broadcast content. We then discuss how, using these results for a particular content type, the use of no-reference metrics can be enabled in place of, or to supplement, existing widely used full-reference quality assessment metrics. We conduct an experimental analysis by transmitting video encoded at different scalability points over a lossy network to ascertain the effect of loss when scalability is employed in one or more dimensions. We analyze these results using a reduced reference metric called delta-blocking, which can detect visual damage of frames that causes a decrease in a user's quality of experience when perceived by the user. If the levels of packet loss are excessively high, this can lead the decoder to drop some video frames. To combat this type of frame loss, we propose a simple windowing algorithm that can automatically re-align the corresponding values for reduced-reference comparison, allowing for video quality monitoring to continue.]]></description>

			<title><![CDATA[Estimating Scene-Oriented Pseudo Depth With Pictorial Depth Cues]]></title>
			<link><![CDATA[http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6484918]]></link>
			<description><![CDATA[Estimating depth information from a single image has recently attracted great attention in 3D-TV applications, such as 2D-to-3D conversion owing to an insufficient supply of 3-D contents. In this paper, we present a new framework for estimating depth from a single image via scene classification techniques. Our goal is to produce perceptually reasonable depth for human viewers; we refer to this as pesudo depth estimation. Since the human visual system highly relies on structural information and salient objects in understanding scenes, we propose a framework that combines two depth maps: initial pseudo depth map (PDM) and focus depth map. We use machine learning based scene classification to classify the image into one of two classes, namely, object-view and non-object-view. The initial PDM is estimated by segmenting salient objects (in the case of object-view) and by analyzing scene structures (in the case of non-object-view). The focus blur is locally measured to improve the initial PDM. Two depth maps are combined, and a simple filtering method is employed to generate the final PDM. Simulation results show that the proposed method outperforms other state-of-the-art approaches for depth estimation in 2D-to-3D conversion, both quantitatively and qualitatively. Furthermore, we discuss how the proposed method can effectively be extended to image sequences by employing depth propagation techniques.]]></description>

			<title><![CDATA[QoE-Oriented Adaptive SVC Decoding in DVB-T2]]></title>
			<link><![CDATA[http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6509401]]></link>
			<description><![CDATA[Associating DVB-T2 and Scalable Video Coding (SVC) constitutes an efficient way for broadcasting added-value video services, such as HDTV and 3D TV, to end-users. The ultimate objective of this new approach of broadcasting video services is to ensure high Quality of Experience (QoE) for end users. Whilst Quality of Service (QoS) is the collective effect of performance that determines the degree of satisfaction of a user of a service, QoE reflects more accurately the user experience, as it is based on human perception when evaluating the video quality. Maximizing user QoE is thus becoming a crucial requirement when deploying new broadcast platforms for the provisioning of high quality video services. The contributions of this paper are two-fold. At first, we introduce a reference-less QoE measurement tool dedicated to SVC coding. Based on a learning function, this tool is able to learn the non-linear relationship between parameters affecting video quality and perceived user QoE. According to several experiments carried out using this tool, we demonstrate that decoding all SVC layers is not always efficient to achieve high user QoE, mostly when SVC enhanced layers experience packet losses. For the sake of maintaining a good QoE, it is worthwhile withdrawing enhanced layers experiencing packet losses and not displaying them to end-users. Based on this observation, we propose a QoE-Based Adaptive SVC Decoding (QoE-BASD) algorithm that assists a video receiver to select the appropriate SVC layers for video decoding in order to maximize QoE. We evaluate the performance of the proposed solution: (i) analytically, by using discrete Markov Chains to model the proposed solution; and (ii) via OPNET-based computer simulations. The obtained results are encouraging, and illustrate the gain achieved by QoE-BASD when compared to the conventional approach.]]></description>

			<title><![CDATA[A Joint Rate Control Scheme in a Hybrid Stereoscopic Video Codec System for 3DTV Broadcasting]]></title>
			<link><![CDATA[http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6479246]]></link>
			<description><![CDATA[In this paper, a frame-level joint rate control scheme for both intra- and inter-predictive coding is first introduced for a hybrid video codec system that independently encodes the two-view sequences of a stereoscopic video. The proposed rate control scheme jointly works on the left view encoder of MPEG-2 Video and the right view encoder of an H.264/AVC for stereoscopic video input, and is formulated as optimization problems that allow control of the output bit rates of both encoders in the sense that: 1) the sum of the two decoded video qualities is maximized, and 2) the quality difference is maintained around a desired level for a given target bit budget at the same time. In order to verify the effectiveness of the proposed joint rate scheme, it is compared with an independent rate control scheme. The experimental results show that the joint rate control scheme effectively regulates the output bitstreams of the hybrid encoders based on MPEG-2 Video and H.264/AVC. The joint rate control scheme achieves average 0.71 dB gain in PSNR and 67.07% reduction in the MSE of PSNR difference for I-frame only, average 0.54dB gain and 91.08% reduction for IPPP coding, and average 0.32dB gain and 79.01% reduction for IBBP coding.]]></description>

			<title><![CDATA[A 3DTV Broadcasting Scheme for High-Quality Stereoscopic Content Over a Hybrid Network]]></title>
			<link><![CDATA[http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6512023]]></link>
			<description><![CDATA[Various methods are used to provide three-dimensional television (3DTV) services over a terrestrial broadcasting network. However, these services cannot provide high-quality 3D content to consumers. It is because current terrestrial broadcast networks are allocated with limited bandwidths to transmit 3D content while 3D content requires larger bandwidth compared to that of 2D content. To overcome this limitation, this paper proposes a hybrid 3DTV broadcasting system, which utilizes both a terrestrial broadcast network and a broadband network. In the proposed system, two elementary streams of left and right views for a stereoscopic video service are transmitted over a terrestrial broadcasting network and a broadband network, respectively. In addition, the proposed system suggests a new mechanism for synchronization between these two elementary streams. The proposed scheme can provide high-quality 3DTV service regardless of bandwidth of the terrestrial broadcast network while maintaining backward compatibility with a 2D DTV broadcasting service.]]></description>

			<title><![CDATA[Constellation Rotation for DVB Multiple Access Channels With Raptor Coding]]></title>
			<link><![CDATA[http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6509923]]></link>
			<description><![CDATA[In this paper we investigate a technique for increasing the capacity of a Digital Video Broadcasting&#x2014;Return Channel via Satellite (DVB-RCS) system. In our previous work, we proposed a scheme consisting in adding a non-orthogonal interfering source to a DVB-RCS channel carrying data from an existing source. The inclusion of the new source does not cause bandwidth increase. The secondary source uses Raptor code. The destination will use successive decoding. It decodes the interfering source first, and after its removal, decodes the main source. In this paper, we generalize our work to allow possibility of decoding either the secondary source data (as in our previous work) or the main source data first. We investigate the performance and delay for each decoding scheme. Since the channels are non-orthogonal, it is possible that for some power allocation scenarios constellation points get erased. To address this problem, we use constellation rotation. The constellation map of the secondary source is rotated to increase the average distance between the points in the constellation resulting from the superposition of the main and interfering sources' constellations. Finally, we determine the optimum constellation rotation angle for the interfering source analytically and confirm it with simulations.]]></description>

			<title><![CDATA[Rotated Constellations for Improved Time and Frequency Diversity in DVB-NGH]]></title>
			<link><![CDATA[http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6513233]]></link>
			<description><![CDATA[In this paper, we investigate the potential gains that can be obtained with rotated constellations in DVB-NGH, the next-generation mobile broadcasting standard. Rotated constellations exploit the concept of signal-space diversity (SSD) to increase the diversity order of bit-interleaved coded modulation (BICM) at the expense of higher demodulation complexity without the need of additional transmission power or bandwidth. Two-dimensional rotated constellations (2DRC) were originally included in DVB-T2 (terrestrial second generation) to improve the reception robustness in fading channels. DVB-NGH inherits the same 2DRC from DVB-T2 and includes four-dimensional rotated constellations (4DRC) for certain configurations. Moreover, the standard has adopted a new component interleaver optimized for the utilization of rotated constellations with long time interleaving (TI) and time-frequency slicing (TFS). In this context, the additional robustness of rotated constellations is very interesting to counter the presence of signal outages in the time and frequency domains. To investigate the potential gains of 2DRC and 4DRC, we employ an information-theoretic approach based on mutual information, as well as physical layer simulations in DVB-NGH systems. The results reveal that rotated constellations are important to increase the diversity gains of long TI and TFS, and also to reduce the zapping time perceived by the users.]]></description>

			<description><![CDATA[This paper provides minimum C/N values for correct reception of DVB-T2 signals under fixed reception conditions. The C/N values are obtained after analyzing the results of field and laboratory trials. The field measurements were taken in a middle-sized city, along 33 locations, with MFN and SFN configurations. Both the system configuration options (constellation and code rate, FFT size, pilot pattern, and rotated constellations) and the propagation channel are taken into account to quantify their influence on the reception requirements. DVB-T was also measured and both systems are compared. The final objective is to provide the broadcasters with some guides based on measurements to optimize the DVB-T2 networks by choosing the parameters that best fit their needs.]]></description>

			<title><![CDATA[Semi-Automated Mobile TV Service Generation]]></title>
			<link><![CDATA[http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6515311]]></link>
			<description><![CDATA[Mobile Digital TV (MDTV), the hybrid of Digital Television (DTV) and mobile devices (such as mobile phones), has introduced a new way for people to watch DTV and has brought new opportunities for development in the DTV industry. Nowadays, the development of the next generation MDTV service has progressed in terms of both hardware layers and software, with interactive services becoming one of the future trends. However, current MDTV interactive service generation process relies too much on commercial solutions, resulting in most parts of the process being proprietary. In addition, this has increased the technical demands for developers and the cost of producing and maintaining MDTV services. In light of the aforementioned situation, this paper proposes an innovative MDTV service generation solution, which introduces a semi-automatic creation mechanism to facilitate a less technical and more efficient interactive service creation process. By employing open-standard technologies including XHTML and Java ME for the service presentation the proposed work benefits are twofold. Firstly it helps in reducing the technical demands of MDTV service production for service creators. Secondly it improves the inter-compatibility of the created service application amongst different MDTV standards. Initial test results indicate that the proposed solution allows for a faster and more effective MDTV interactive service generation.]]></description>

			<title><![CDATA[Design and Analysis of a Wireless Switched Digital Video Scheme for Mobile TV Services Over WiMAX Networks]]></title>
			<link><![CDATA[http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6495705]]></link>
			<description><![CDATA[Mobile WiMAX is emerging as one of the most promising systems for 4th generation mobile wireless networks in which it is foreseen that mobile TV services will proliferate. In general, TV applications are bandwidth hogs that cause a challenging capacity problem in wireless networks. To address this challenge, a novel scheme for mobile TV services over WiMAX network, called the wireless switched digital video (WSDV) scheme, is proposed in this paper. Compared with the conventional broadcast or unicast schemes, the hybrid approach introduced in our proposed WSDV approach exploits the merits of two conventional schemes and mitigates their demerits, which enables it to increase wireless capacity for mobile TV services. In addition, we present a WiMAX design tool, based on an analytical model, which facilitates analysis of the influence of some system parameters on wireless capacity. The analytical model can capture the details of WiMAX resource allocation and take into consideration the popularity of the mobile TV contents being viewed by users&#x2014;enabling it to provide an accurate estimate of the amount of bandwidth required for WiMAX TV services and also enabling a designer to optimally select the number of channels via the WSDV service while meeting a desired level of blocking probability. In addition, we demonstrate that our proposed optimized scheme outperforms the conventional schemes with respect to blocking probability. Finally, an end-to-end solution to the WSDV scheme is also presented.]]></description>

			<link><![CDATA[http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6490354]]></link>
			<description><![CDATA[User mobility, heterogeneity of networks and network technologies, variety of mobile devices (e.g., different operating systems, display size, CPU capabilities, battery limitations), and wide range of video-centric applications (e.g., video on demand, video games, live video streaming, video conferences, surveillance) open up the demand for user-centric solutions that adapt the video application to the underlying network conditions and device characteristics. In addition, the absence of battery improvements suitable to meet the growing power requirements and the need for green Information and Communications Technologies ICT provides strong motivation for researchers to develop energy efficient techniques to manage and reduce power consumption in next-generation wireless networks, while still meeting high user quality expectations. In this context, we propose adapt-or-handover, a hybrid multimedia delivery solution, which balances the benefits of multimedia content adaptation and of network selection to decrease power consumption in a heterogeneous wireless network environment. The proposed solution is analyzed and comparatively tested through simulations. The results show how, by using adapt-or-handover, the users benefit from up to 31% energy savings with insignificant degradation in quality, in comparison with other energy efficient solutions.]]></description>

			<link><![CDATA[http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6412775]]></link>
			<description><![CDATA[The black-haul infrastructures of today's wireless operators must support the triple-play services demanded by the market or regulatory bodies. To cope with increasing capacity demand, in our previous work, we have developed a cost-effective heterogeneous layer 2.5 wireless back-haul (WiBACK) architecture, which leverages the native multicast capabilities of broadcast technologies such as DVB to off-load high-bandwidth broadcast content delivery. Furthermore, our architecture provides support for unidirectional technologies on the data and the control plane. This adopts a centralized coordinator approach, in which coordinator nodes install so-called management and data pipes. No routing state is kept at plain WiBACK nodes, which merely store QoS-aware pipe forwarding state. Consequently, the architecture requires a reliable protocol to push resource allocation and pipe forwarding state into the network, considering possibly unidirectional connectivity. Such a protocol, whose task is related to MPLS label distribution, is essential during the initial forming of WiBACK topologies and during regular network operations to reliably manage the data pipes. In this paper, we present a novel approach to extend our IEEE 802.21-inspired WiBACK TransportService and, based upon this, the design of an RSVP-TE-style pipe signalling protocol using nested hop-by-hop request/response MIH transactions that supports signalling over unidirectional technologies. A thorough evaluation and successful testbed deployments show that this protocol reliably signals pipe state even under high loss conditions.]]></description>

			<description><![CDATA[High peak-to-average power ratio (PAPR) of the transmitted signal is one of the limitations to employing orthogonal frequency division multiplexing (OFDM) system. In this paper, we propose a new nonlinear companding algorithm that transforms the OFDM signals into the desirable statistics form defined by a linear piecewise function. By introducing the variable slopes and an inflexion point in the target probability density function, more flexibility in the companding form and an effective trade-off between the PAPR and bit error rate performances can be achieved. A theoretical performance study for this algorithm is presented and closed-form expressions regarding the achievable transform gain and signal attenuation factor are provided. We also investigate the selection criteria of transform parameters focusing on its robustness and overall performance aspects. The presented theoretical analyses are well verified via computer simulations.]]></description>

			<title><![CDATA[Adaptive HPA Linearization Technique for Practical ATSC DTV System]]></title>
			<link><![CDATA[http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6516520]]></link>
			<description><![CDATA[In the digital television (DTV) broadcasting system, high power amplifier (HPA) is the most essential device to expand the service availability and coverage. However, as the input power level of HPA increases, the HPA is driven into the saturation mode and HPA output signal suffers nonlinear distortion. HPA nonlinearity is potentially responsible for adjacent channel interference and inter-symbol interference (ISI). To prevent these negative effects, digital pre-distortion (DPD) is one of the most widely used techniques for the HPA linearization. In order to estimate the HPA nonlinearity, DPD technique requires a feedback signal, which needs to be appropriately down converted and digitized from HPA output. However, since the feedback signal might be generally influenced by offset error, it is important to reduce the offset error in order to improve HPA linearization. In this paper, an adaptive DPD technique based on iterative look-up table (LUT) update and adaptive acquisition is proposed. The proposed DPD technique is validated on the advanced television systems committee (ATSC) terrestrial DTV broadcasting system by computer simulation and laboratory test.]]></description>

			<title><![CDATA[Traffic and Statistical Multiplexing Characterization of 3-D Video Representation Formats]]></title>

			<description><![CDATA[The network transport of 3-D video, which contains two views of a video scene, poses significant challenges due to the increased video data, compared to a conventional single-view video. Addressing these challenges requires a thorough understanding of the traffic and multiplexing characteristics of the different representation formats of a 3-D video. We examine the average bitrate-distortion (RD) and bitrate variability-distortion characteristics of three main representation formats. Specifically, we compare multiview video (MV) representation and encoding, frame sequential (FS) representation, and side-by-side (SBS) representation, whereby conventional single-view encoding is employed for the FS and SBS representations. Our results for long 3-D videos in the full HD format indicate that the MV representation and encoding achieves the highest RD efficiency, while exhibiting the highest bitrate variabilities. We examine the impact of these bitrate variabilities on network transport through extensive statistical multiplexing simulations. We find that when multiplexing a small number of streams, the MV and FS representations require the same bandwidth. However, when multiplexing a large number of streams or smoothing traffic, the MV representation and encoding reduces the bandwidth requirement relative to the FS representation.]]></description>

			<title><![CDATA[DIRECT Mode Early Decision Optimization Based on Rate Distortion Cost Property and Inter-view Correlation]]></title>
			<link><![CDATA[http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6509444]]></link>
			<description><![CDATA[In this paper, an Efficient DIRECT Mode Early Decision (EDMED) algorithm is proposed for low complexity multiview video coding. Two phases are included in the proposed EDMED: 1) early decision of DIRECT mode is made before doing time-consuming motion estimation/disparity estimation, where adaptive rate-distortion (RD) cost threshold, inter-view DIRECT mode correlation and coded block pattern are jointly utilized; and 2) false rejected DIRECT mode macroblocks of the first phase are then successfully terminated based on weighted RD cost comparison between 16<formula formulatype="inline"> <tex Notation="TeX">$,times,$</tex></formula>16 and DIRECT modes for further complexity reduction. Experimental results show that the proposed EDMED algorithm achieves 11.76% more complexity reduction than that achieved by the state-of-the-art SDMET for the temporal views. Also, it achieves a reduction of 50.98% to 81.13% (69.15% on average) in encoding time for inter-view, which is 29.31% and 15.03% more than the encoding time reduction achieved by the state-of-the-art schemes. Meanwhile, the average Peak Signal-to-Noise Ratio (PSNR) degrades 0.05 dB and average bit rate increases by <formula formulatype="inline"><tex Notation="TeX">${-}{0.37%}$</tex></formula>, which is negligible.]]></description>
