芭乐借UGC打造新媒体影视内容整合营销平台

2013年可谓UGC重磅回归的一年,在移动互联网对PC互联网带来革命性j中击、视频行业并购调整频繁的年月,国内视频网站再次开始重新炒热UGC概念。包括优酷土豆、酷6网、PPS和乐视网等在内的视频网站都纷纷开始UGC宣传计划。YouTube早在2005年就全面引入了UGC概念,并创出了独有的UGC模式,随后国内最早的一批视频网站包括土豆、优酷等也都有在模仿YouTube,纷纷涉足UGC开拓市场积累用户与品牌。随着市场的加剧和UGC在国内的水土不服,视频网站逐渐向Hulu长视频模式转型,     

网络视频内容生产模式的发展与变化——从UGC到PGC的并行之路

2005年诞生视频分享网站以来,网络视频的主要内容基本可以分为用户生产内容（UGC）与专业生产内容（PGC）.在早期UGC内容发展迅猛,并为网络亚文化发展提供了新的土壤.一部分UGC制作人通过自身努力或者与专业人士合作把一部分主题的UGC内容做精成为PGC内容;同时,平台为了提高自身的内容质量从电视行业引进PGC内容.对于UGC内容,运营商们也并没有抛弃,UGC与PGC都发挥各自的作用,帮助网络视频行业更好地为用户提供服务.     

UGC将是移动互联网的新热点

UGC（user generated content）被称为“用户原创内容”.即用户将自己DIY的内容通过互联网平台进行展示或者提供给其他用户的方式。社区网络、视频分享、博客和播客都是UGC的主要应用形式.YouTube、MySpace等网站都被看作是UGC的成功案例。     

网络电视、NGB和网络新媒体

互联网作为媒体的传输平台可以传输分发文字、图片和视频等媒体内容,今天报纸、通讯社等传统平面媒体网站也在发展包括视频在内的多媒体内容。互联网可以以广播、点播、下载等多种方式分发视频内容。既可以是专业制作的内容,也可以是用户自制的内容（UGC）。互联网正在成为频道广播以外的另一个传输媒体,网络电视台的兴起正在改变电视的播出模式．从线性向非线性演化。网络电视台有利于传统媒体与新媒体的联动融合。在同一互联网上分发传播。而互联网跨越国界的通达性克服了一般电视作为本地媒体的局限性。

基于Actel FPGA的RGB转ITU656方案

随着计算机软硬件技术的迅猛发展,视频技术也得到了飞速发展。现在,数字娱乐、多媒体通信、高清晰度电视、数字电视、宽带网络等都是围绕如何有效地交流视频信息而展开研究的。但是,由于视频信息十分丰富且信息量大,故对视频信息的处理、传输、存储和显示等都提出了新的要求。因此,视频技术     

和用户一起创造价值

运营方不需要支付高昂的影视节目版权费，也不必下功夫做出力又难讨好的自制节目，让网民生成节目和其分成收益，而自己只需要搭建合理的平台、营运方式和增加宽带，这就是谷歌旗下视频网站Youtobe的UGC模式。目前国内大多视频网站并没有找到合适的UGC架构，而只停留在传统的运曹方式上艰难的生存着。当然影响UGC发展的因素很多，网站能否搭建良好的用户体验平台、合理的盈利分成系统将是一个至关重要的环节。

Resolution Enhancement Technology:Integrated Process Solutions using OPC

DUV lithography, using the 248 nm wavelength, is a viable manufacturing option for devices with features at 130 nm and less. Given the low kl value of the lithography, integrated process development is a necessary method for achieving acceptable process latitude. The application of assist features for rule based OPC requires the simultaneous optimization of the mask, illumination optics and the resist.Described in this paper are the details involved in optimizing each of these aspects for line and space imaging.A reference pitch is first chosen to determine how the optics will be set. The ideal sigma setting is determined by a simple geometrically derived expression. The inner and outer machine settings are determined, in turn,with the simulation of a figure of merit. The maximum value of the response surface of this FOM occurs at the optimal sigma settings. Experimental confirmation of this is shown in the paper.Assist features are used to modify the aerial image of the more isolated images on the mask. The effect that the diffraction of the scattering bars (SBs) has on the image intensity distribution is explained. Rules for determining the size and placement of SBs are also given.Resist is optimized for use with off-axis illumination and assist features. A general explanation of the material' s effect is discussed along with the affect on the through-pitch bias. The paper culminates with the showing of the lithographic results from the fully optimized system.     

Cost-effective test solutions for smart card and other integrated flash applications

From its emergence in the late 1980s as a lower cost alternative to early EEPROM technologies, flash memory has evolved to higher densities and speedsand rapidly growing acceptance in mobile applications.In the process, flash memory devices have placed increased test requirements on manufacturers. Today, as flash device test grows in importance in China, manufacturers face growing pressure for reduced cost-oftest, increased throughput and greater return on investment for test equipment. At the same time, the move to integrated flash packages for contactless smart card applications adds a significant further challenge to manufacturers seeking rapid, low-cost test.     

Theoretical analysis of the relationship between the Brillouin gain coefficient and the strain in the optical-fiber sensors

The relation between the power of the Brillouin signal and the strain is one of the bases of the distributed fiber sensors of temperature and strain. The coefficient of the Bfillouin gain can be changed by the temperature and the strain that will affect the power of the Brillouin scattering. The relation between the change of the Brillouin gain coefficient and the strain is thought to be linear by many researchers. However, it is not always linear based on the theoretical analysis and numerical simulation. Therefore, errors will be caused if the relation between the change of the Brillouin gain coefficient and the strain is regarded as to be linear approximately for measuring the temperature and the strain. For this reason, the influence of the parameters on the Brillouin gain coefficient is proposed through theoretical analysis and numerical simulation.     

An improved parallel thinning algorithm with two subiterations

The parallel thinning algorithm with two subiterations is improved in this paper. By analyzing the notions of connected components and passes, a conclusion is drawn that the number of passes and the number of eight-connected components are equal. Then the expression of the number of eight-connected components is obtained which replaces the old one in the algorithm. And a reserving condition is proposed by experiments, which alleviates the excess deletion where a diagonal line and a beeline intersect. The experimental results demonstrate that the thinned curve is almost located in the middle of the original curve connectivelv with single pixel width and the processing speed is high.     

Novel fiber-optical interferometer with miniaturized probe for in-hole measurements

Today, micro-system technology and the development of new MEMS （Micro-Electro-Mechanical Systems） are emerging rapidly. In order for this development to become a success in the long run, measurement systems have to ensure product quality. Most often, MEMS have to be tested by means of functionality or destructive tests. One reason for this is that there are no suitable systems or sensing probes available which can be used for the measurement of quasi inaccessible features like small holes or cavities. We present a measurement system that could be used for these kinds of measurements. The system combines a fiber optical, miniaturized sensing probe with low-coherence interferometry, so that absolute distance measurements with nanometer accuracy are possible.     

Study of waveguide coupling efficiency in hybrid silicon lasers

This paper presents a new method to increase the waveguide coupling efficiency in hybrid silicon lasers. We find that the propagation constant of the InGaAsP emitting layer can be equal to that of the Si resonant layer through improving the design size of the InP waveguide. The coupling power achieves 42% of the total power in the hybrid lasers when the thickness of the bonding layer is 100 nm. Our result is very close to 50% of the total power reported by Intel when the thickness of the thin bonding layer is less than 5 nm. Therefore, our invariable coupling power technique is simpler than Intel＇s.     

Teleportation of an arbitrary unknown N-qubit entangled state under the controlling of M controllers

A new quantum protocol to teleport an arbitrary unknown N-qubit entangled state from a sender to a fixed receiver under M controllers(M < N) is proposed. The quantum resources required are M non-maximally entangled Greenberger-Home-Zeilinger (GHZ) state and N-M non-maximally entangled Einstein-Podolsky-Rosen (EPR) pairs. The sender performs N generalized Bell-state measurements on the 2N particles. Controllers take M single-particle measurement along x-axis, and the receiver needs to introduce one auxiliary two-level particle to extract quantum information probabilistically with the fidelity unit if controllers cooperate with it.     

Diode-end-pumped Nd:YVO4/LBO lasers with 4.2W continuous-wave output at 457 nm

A continuous-wave (CW) 457 nm blue laser operating at the power of 4.2 W is demonstrated by using a fiber coupled laser diode module pumped Nd: YVO4 and using LBO as the intra-cavity SHG crystal With the optimization of laser cavity and crystal parameters, the laser operates at a very high efficiency. When the pumping power is about 31 W, the output at 457nm reaches 4.2 W, and the optical to optical conversion efficiency is about 13.5% accordingly. The stability of the out putpower is better than 1.2% for 8 h continuously working.     

A rigorous proof of MIMO channel capacity’s increase with antenna number

It is well known that adding more antennas at the transmitter or at the receiver may offer larger channel capacity in the multiple-input multiple-output（MIMO） communication systems. In this letter, a simple proof is presented for the fact that the channel capacity increases with an increase in the number of receiving antennas. The proof is based on the famous capacity formula of Foschini and Gans with matrix theory.
