基于5G通信技术的多信道数字媒体信息快速采集方法

为提高对数字媒体信息的采集准确率,提出了基于5G通信技术的多信道数字媒体信息快速采集方法。首先,设计面向5G的资源分配体系,通过信息传输业务流分配最佳的数字媒体资源。计算数据流的虚拟带宽满足时延的要求,根据不同传输优先级调度待采集的数字媒体信息。然后,运用全双工的通信模式控制无线传感网络,获得同一时隙较多的并发传输链路数量,再分配信息采集信道,根据网络节点的初始状态计算节点传输能力,运用博弈论自主分配采集信道。最后,根据决策选择,占用最大效用值所在的采集信道,运用DOM树快速生成信息采集路径,再通过链接扩展生成新的规则来获取完整信息从而完成采集。实验结果表明,相比于传统方法,该方法的采集准确率更高。

信息数字化多媒体教学在临床医学教学中的应用

随着计算机技术的迅速发展,人类社会已进入信息化时代,信息技术本身也正在对教育的改革产生深远的影响,并且已成为教育现代化的核心和成功的关键。为了从根本上优化教育管理和教学过程,各个国家都在提高教育计算机化的水平,并且已成为世界范围的教育改革潮流和改革趋势。临床医学教学信息量大,常常难以直接展示人体的结构、疾病发生及发展过程等教学内容,以信息数字化的计算机多媒体方式可达到较好的教学效果。人类的记忆是网状结构,传统的线性结构教学方法限制了学生自由联想能力的发挥,计算机多媒体技术是非线性的,更能发挥个体的个性,加快获取知识的速度,提高获取知识的能力。临床医学教育中,计算机技术的信息数字化应用,将对教育手段、方法、学生的适应和创造能力都将产生深刻的影响。1 信息数字化计算机多媒体教学的优越性 临床医学教学是一实践性很强的学科,传统的临床医学教学,局限于课堂和书本上,教师的课堂授课只能在一个单位时间内为一部分学生所享用。现代科学技术的发展为临床医学教学提供了新的手段和广阔的前景,计算机多媒体技术在教学上的应用,增加了教学的广度、深度和可视度。

面向数字媒体的高性能分布式存储系统的研究与应用

Digital Media Ethics： Challenges Between the Public and the Private for ICTs

There have never been more ways for us to ＂communicate＂ than what we may have today as we keep developing new technologies that allow us with alternative forms of interaction other than face-to-face conversation. Our age indeed distinguishes itself by its ever more rapid transformations in the kinds of mediation for such encounters. But, especially when they are new, technologies may deeply affect how we see the world, our communities, our relationships, and ourselves. For, as people usually respond to new media with much excitement as well as a big amount of confusion, and these media may conduct to social and cultural reorganization, they should as well incite more sober reflections about such changes before they become so taken for granted to appear as almost ＂invisible＂

Towards a multilingual, multimedia and multimodal digital library platform

The China-US Million Book Digital Library Project （Million Book Project） is an intemational cooperation program between China and the US. However, one million digitized books are considered not to be the ultimate goal of the project, but a first step towards universal access to human knowledge. In particular, there are four challenges about the new way to analyze, process, operate, visualize and interact with digital media resource in this library. To tackle these challenges, North China Centre of Million Book Project （in Chinese Academy of Sciences） has initiated several innovative research projects in areas such as multimedia content analysis and retrieval, bilingual services, multimodal information presentation, and knowledge-based organization and services. In this keynote speech, we simply review our work in these areas, and argue that by technological cooperation with these innovation research topics, the project will develop a top-level digital library platform for the million book library.

Public Service Media Journalism and Democracy in the Digital Age

In the digital age, when we witness the rapid proliferation of platforms and services, European societies continue debating the role and the future of public service media （PSM）. In the new digital environment, public service broadcasting/media, which for a number of social and cultural reasons have been at the core of the European media system, faces the capital question--What democracy do public operators strive for and how can they accomplish it？ PSM has to be at the vanguard of the complex process of media transformation in the information society and particularly of the formation of novel journalistic culture which besides the values of ethical and innovative content should also serve the principles of good and efficient governance.

Research on the Digital Communication Strategy of Intangible Cultural Heritage under the New Media Environment

In the field of intangible cultural heritage＇ s digital protection, a lot of research work has been made by all countries in the world, while the research on the digital commuuication of intangible cultural heritage is few and especially rarely seen in China. Under the premise, in this paper, the factors influencing intangible cultural heritage in the communication process are analyzed based on the information characteristics of intangible cultural heritage and the advantages of I-Space framework model in researching information transfer. Also, combined with the birch bark making technology in Heilongjiang province, the knowledge-based and signified communication strategy of intangible cultural heritage is proposed, aiming at providing new ideas for the researches on the digital communication of intangible cultural heritage.
