This paper presents the implementation of the OFDM demodulator and the Viterbi decoder, proposed as part of a wireless High Definition video receiver to be integrated in an FPGA. These blocks were implemented in a Xilinx Virtex-6 FPGA. The complete system was previously modeled and simulated using MATLAB/Simulink to extract important hardware characteristics for the FPGA implementation.

The present paper paves the way toward the automatic tracking of the live camcorder (in theater, on a TV/advertising screen) video sequences. In this respect, a video fingerprinting method based on the intimate statistical model of the DWT coefficients and on a dynamic resynchronization between original and camcorded frames is advanced. Evaluated in partnership with the French cinematography authority, this method resulted in probabilities of missed detection and false alarm of 0.00009 and 0.0036, respectively while its precision and recall ratios are of 0.72.

This paper proposes an improved additional data transmission (ADT) system based on low density parity check (LDPC) code which can transmit an additional data stream in the Advanced Television Systems Committee (ATSC) terrestrial digital television system. The LDPC code based ADT system can offer an additional data of rate up to a few megabits per second (Mbps) which is significantly increased compared to the conventional data transmission schemes used in the transmitter identification system.

In this paper we introduce the Starting-Energy Fair Queuing (SEFQ), a novel class of energy-aware scheduling algorithms aim to guarantee a target lifetime to mobile devices while providing proportional energy consumption and time-constraint meeting to tasks. With the extension of fair queuing to the energy domain, energy consumption of CPU is managed in a way that each task is guaranteed a share of the average power of a fixed period. The simulation results show that the performance of time-sensitive tasks can be traded-off with their fairness.

The present paper provides the proof-of-concepts for the use of the emerging HTML5 open standard as an application virtualization tool. By advancing an architecture based on the client-server model, it is demonstrated that the underlying performances in terms of visual quality, uplink/downlink network consumption and user experience cope with the nowadays expectations of a mobile thin client. The quantitative results refer to a Samsung Galaxy 10.1 tablet remotely accessing Gedit and Epiphany applications.

This paper presents the implementation of a single FPGA intellectual property (IP) core for channel coding and interleaving used in Digital Video Broadcasting, second generation (DVB-T2). DVB-T2 is the extension of the television standard DVB-T, issued by the consortium DVB, and is devised for the broadcast transmission of digital terrestrial television. The higher offered bit rate, with respect to its predecessor DVB-T, makes it a suited system for carrying high definition TV (HDTV) signals on the terrestrial TV channel. In this paper we specifically target the version suitable for China Multimedia Mobile Broadcast (CMMB) standard that works on the 2,635 to 2,660 MHz frequency band to provide 25 video and 30 audio channels. The main contribution is the design and development of forward error correction (FEC) part for mobile multimedia broadcast system, its estimation of power dissipation and optimization. The FEC part includes Reed Solomon (RS) encoder and byte interleaver, low density parity check (LDPC) encoder and bit interleaver. All these sub-modules have been implemented and integrated for the target device Stratix III E (EP3SE50F780C4N). The design has been coded in verilog-HDL and synthesized using Quartus II 8.1 software tool. PowerPlay Power Analyzer tool provided by Altera with Quartus II software has been used for the estimation of power dissipation. Stratix III logic array block level programmable power technology and clock gating technique has been used for power optimization.
本文介绍了用于第二代数字视频广播(DVB-T2)的信道编码和交织的单FPGA知识产权(IP)核心的实现。DVB- t2是DVB联盟发布的电视标准DVB- t的扩展，是为数字地面电视的广播传输而设计的。与其前身DVB-T相比，提供的比特率更高，使其成为在地面电视频道上传输高清电视(HDTV)信号的合适系统。在本文中，我们专门针对适合中国多媒体移动广播(CMMB)标准的版本，该版本工作在2,635至2,660 MHz频段，提供25个视频和30个音频通道。主要贡献是移动多媒体广播系统前向纠错(FEC)部分的设计与开发，其功耗估计与优化。FEC部分包括RS (Reed Solomon)编码器和字节交织器、低密度奇偶校验(LDPC)编码器和位交织器。所有这些子模块都已经在目标器件Stratix III E (EP3SE50F780C4N)上实现和集成。本设计采用verilog-HDL进行编码，并使用Quartus II 8.1软件工具进行合成。采用Altera提供的PowerPlay Power Analyzer工具和Quartus II软件进行功耗估算。采用Stratix III逻辑阵列块级可编程电源技术和时钟门控技术进行电源优化。

For the past two decades, the feature size in the integrated circuits industry has been shrinking continuously. The higher number of gates integrated on a die has been translated into soaring demand for on-chip communication. Different multilevel signaling techniques with and without bus encoding or error control coding have been proposed to deal with the tradeoffs between reliability and power consumption. However, the signal integrity analysis to evaluate these techniques has been often performed based on pessimistic static noise margins. By applying dynamic noise margins, in this paper, we propose a new method to model the receivers in 4-PAM signaling scheme as one of popular alternatives for binary signaling. The outcome of this research demonstrates significant improvement in predicting the reliability performance of the chosen signaling scheme. The more realistic signal integrity analysis presented here can be utilized in favor of various design optimizations, for example, shorter spaces between wires, longer interconnects, faster transitions and lower signaling voltages.

Content discovery has historically been a painful process of repeatedly scanning a large gallery of images or, worse, a textual list of shortened titles. The user experience became a race to see whether the user's thumb or brain got numb first. MEMS and enhanced metadata, combined with better connectivity allow for a navigation experience that is actually enjoyable in its own right. This paper reviews some of the key steps necessary to achieve that.

The use of intracranial pressure (ICP) monitoring is supported and recommended in the neurosurgical and neurological assessment. Acute and long-term ICP measurement is desirable for providing an insight into the mechanism of the head injury and aiding post neurological disorders treatment. Two different embedded wireless microwave devices for monitoring of ICP have been designed and investigated for research and clinical diagnoses. This paper presents a comparative study of these devices, and describes their main features and measurement procedures.
