深入理解信息无障碍标准

据联合国统计,残疾人问题是各国面临的重大社会问题。目前信息技术飞速发展,残疾人若不能越过无形的信息屏障,有进一步被边缘化的趋势。信息无障碍是指任何人(无论健全人、残疾人、年轻人还是老年人)在任何情况下都能平等地、方便地、无障碍地获取信息、利用信息。信息无障碍提倡人们在设计和提供信息通信产品和服务时全面考虑残障人士和非残障人士的统一需求,让全社会所有的人都能以平等的机会和差异不大的成本,分享信息技术带来的益处,让更多的弱势人群融入主流社会,享受与普通人一样的生活。国内外的实践证明,实行"国家法规+方针政策+技术标准"的运作模式,是推动残障人士事业发展的最有效的举措,它可以促使国家的相关政策法规得到最有效的贯彻并产生最佳的预期效果。本刊继第3期信息无障碍领域国际标准动态等报道之后,本期特别邀请同济大学朱双六老师撰写《深入理解信息无障碍标准》,以正确理解和准确运用标准为出发点,希望长期困扰行业发展的瓶颈问题以此得到解决。同时,从本期开设"信息无障碍标准化系列研究"专栏,计划连载七期,全面展示我国信息无障碍领域标准化研究成果和最新进展,为推动信息无障碍产业健康、有序发展尽绵薄之力。敬请关注。

Transform and embedded coding techniques for maximum efficiency and random accessibility in 3-D scalable compression.

This study investigates random accessibility and efficiency enhancements in highly scalable video and volumetric compression. With the advent of interactive multimedia technology, random accessibility has emerged as an increasingly important consideration in the design and optimization process. In this paper, we assess the impact that the transform, embedded coding components, and code-block configurations have on the compression efficiency and accessibility of a scalable codestream. We develop performance bounds on techniques which exploit temporal redundancy within the confines of a feed-forward compression system. We also examine their random access properties to argue the significance of motion-adaptive subband transforms. When information-theoretic measures are used to determine the potential benefits of three-dimensional (3-D) context coding, we find that most of the coding gain is attributed to code-block extension, rather than interslice context modeling itself. To gain further insight into the tradeoffs that the coding part has to offer, we run a series of simulations to determine code-block partitioning strategies which maximize reconstruction quality and space-time localization. The LIMAT framework and EBCOT coding paradigm have laid a solid foundation for further progress in the development of highly scalable 3-D compression systems.

Telecommunication Development--The Third Way

The object of this paper is to define the third way to telecommunication development-suitable to the needs and conditions of the third world countries. It begins with some comments on the present conditions, identifies probable reasons, and defines three fundamental goals for developing nations: 1) rural communication,2) accessibility, and 3) reliability. Based on these three goals, the third way to telecommunication development is defined. The need for an autonomous telecommunication technology center for the third world is emphasized, and its objectives, organization, and implementation are discussed. A need for new systems geared toward increasing accessibility is advocated. As an example, a new concept called the "community telephone" is introduced, which is designed to provide reliable telecommunication service to a small community. At the end, it is concluded that the real implication of the third way to telecommunication development can only be analyzed through further interdisciplinary research.     

Wireless network resource management for Web-based multimedia document services

Advances in wireless technology and availability of portable devices with networking capabilities have enabled ubiquitous Web accessibility. This has created the need to provide advance Internet services to mobile users without causing service failures due to connection migration or handoffs. However, scarcity of wireless resources restricts the provision of multimedia services in wireless networks. We address the issue of managing wireless resources to support Web-based multimedia document services including MPEG-4-based applications, in wireless networks with a high degree of user mobility. In particular, we formulate the resource management problem in wireless networks as an optimization problem with an objective function comprising different quality of presentation parameters.     

The role of media in user participation: Focusing on the knowledge activity in online space

Media technology have been considered a catalyst for boosting communication between the sources of information. Contrary to traditional media, new media which use online communication shows high interactivity properties. This characteristic allows people to participate in collective activities such as discussion, evaluation, or creating documents. Consequently, the role of media in online space has focused on delivering individual knowledge to others rather than just adopting selected information. We studied the effect of media usage patterns on creating knowledge in online communities. In our study, we divided user groups into three based on the degree to which people participate in knowledge collaboration in the online space: active participant, passive participant, and bystander. The results indicate that the active participant group is most likely to use smartphone and tablet PC to create knowledge in online space which means they prefer high accessibility rather than familiar mediators.     

MTNet: Design of a Wireless Test Framework for Heterogeneous Nanometer Systems-on-Chip

The rapid migration to nanometer design processes has brought an unprecedented level of integration by allowing system designers to pack a wide variety of functionalities on-chip, namely, systems-on-a-chip (SoCs). In the meantime, electronic testing becomes an enabling technology for this SoC paradigm, since the integration of various core tests is a big challenge, and has revealed a widening gap between design and manufacturing. In particular, the increasing complexity and density of nanometer SoCs have led to the problem of visibility and accessibility in testing. In this paper, we propose an integrated wireless test framework to resolve the acerbated core accessibility problem and to eliminate the incompatibility between the existing SoC test strategies and the next generation billion-transistor SoC specification. Under such a test strategy, the intra-chip wireless links form the wireless test access mechanism (TAM) to transport test data chip-wide. We present a self-configurable multi-hop wireless test micronetwork, dubbed MTNet, with simple and efficient data transmission protocols, and develop a system level design-for-testability structure. Consequently, we propose a geographic routing algorithm to find the test access paths for the deeply embedded cores and a path driven test scheduling algorithm to design and integrate the MTNet-based SoC test access architecture. Extensive simulation study show the feasibility and applicability of MTNet.
