Many people recognise the important role broadcasters have in providing people with an understanding of environmental issues is often through programmes and other content but broadcasters themselves also have a significant impact on the environment through the process of content creation and distribution. This touches on the editorial and creative challenges of informing audiences about the environment and focuses on the sustainability of programme making and distribution, using the UK and particularly the BBC as an example. In the first case using information from Albert, the UK carbon calculator for the television industry, the carbon footprint of different production workflows will be assessed. Then using research undertaken by BBC R&D and partners the paper will look at the impact of transmission and the energy differences between distribution platforms. In conclusion some thoughts on the challenges facing this industry will be shared as well as some suggestions on where efforts might productively be focused.
许多人认识到广播公司在让人们了解环境问题方面的重要作用,通常是通过节目和其他内容,但广播公司本身也通过内容创作和分发过程对环境产生重大影响。这涉及到向观众宣传环境的编辑和创意挑战,并以英国,特别是英国广播公司为例,关注节目制作和发行的可持续性。在第一个案例中,使用来自英国电视行业碳计算器Albert的信息,将评估不同生产工作流程的碳足迹。然后,利用BBC研发部门和合作伙伴进行的研究,本文将研究传输的影响以及分布平台之间的能量差异。最后,我将分享一些关于该行业面临的挑战的想法,以及一些关于如何有效地集中精力的建议。

This study demonstrates how a maturity model on Green ICT can help organisations improve themselves and become more environmental sustainable in a standard and efficient manner. For this we have used the SURF Green ICT Maturity Model and facilitated the use of this model in four organisations. These organisations participated in a maturity scan, evaluation session to discuss the results of the scan and a questionnaire on the use of the model. This field study showed that individual participants were very positive about the use of such a model and that it provided inspiration for improvement, both to reduce the environmental impact of ICT as well as to use ICT as an green solution for other business processes.
这项研究展示了绿色信息通信技术的成熟度模型如何帮助组织以标准和有效的方式改进自身,并变得更加环保可持续。为此,我们使用了SURF绿色ICT成熟度模型,并促进了该模型在四个组织中的使用。这些组织参加了成熟度扫描、评估会议,讨论扫描结果和关于模型使用的问卷调查。这项实地研究表明,个别参与者对使用这种模式持非常积极的态度,并认为它为改进提供了灵感,既减少了信通技术对环境的影响,又将信通技术作为其他业务流程的绿色解决方案。

In the actual network configuration, content providers are not involved in the universal service programs with a corresponding participation being taxes, funds or compensations. We propose a regulated Internet contract with a free or very small economic participation to access into a limited version of the service with content providers financing participation to broadcast their high bandwidth content. We study a minimum quality of a service as a strategy of public policy over a broadband telecommunication services to create better absorption of technological benefits as a welfare measure for the users. As results we show a positive effect to propose universal service by quality as complement of universal service obligation, the conditions to determine the prices have to be ruled ex-ante by authorities and finally the best market scenario for welfare superior is determined by competition.
在实际的网络配置中,内容提供商不参与普遍服务计划,相应的参与是税收、基金或补偿。我们建议制定一项受监管的互联网合同,允许用户免费或极少的经济参与,以获得有限版本的服务,内容提供商出资参与,以播放其高带宽内容。我们研究了服务的最低质量,作为宽带电信服务的公共政策策略,以更好地吸收技术效益,作为用户的福利措施。结果表明,提出以质量作为普遍服务义务补充的普遍服务具有积极作用,确定价格的条件必须事先由当局裁定,最后,福利优越的最佳市场情景由竞争决定。

The huge growth in the number of connected wireless devices leads to an increasing demand for network connectivity. In this context, aerial networks may play an important role by widening the concept of access networks. This paper describes and analyzes one of the most promising applications of Unmanned Aerial Vehicles, commonly known as drones, in the field of communications: Extending the capacity or coverage of wireless systems through the deployment of aerial communication networks. We present a comprehensive characterization study of an experimental system to deploy an aerial WiFi network. To do so, an Intel Galileo development board is appropriately configured and equipped as a WiFi node playing either the role of an access point in the infrastructure mode or of an intermediate hop in the ad-hoc operational mode. This device is then integrated onboard a drone. We compare both WiFi modes in terms of coverage area, throughput, and energy efficiency. Preliminary results reveal that there is a trade-off between coverage and data rates, for which the infrastructure mode performs better, and energy efficiency, where the ad-hoc mode is more responsive.
连接的无线设备数量的巨大增长导致对网络连接的需求不断增加。在这方面,空中网络可以通过扩大接入网的概念发挥重要作用。本文描述和分析了无人机在通信领域最有前途的应用之一:通过部署空中通信网络来扩展无线系统的容量或覆盖范围。我们提出了一个实验系统的全面表征研究,以部署空中WiFi网络。为此,英特尔伽利略开发板被适当地配置和装备为WiFi节点,在基础设施模式中扮演接入点的角色,或在ad-hoc操作模式中扮演中间跳点的角色。然后将该设备集成到无人机上。我们比较了两种WiFi模式的覆盖范围、吞吐量和能源效率。初步结果表明,在覆盖率和数据速率之间存在权衡,其中基础设施模式表现更好,而能源效率,其中ad-hoc模式响应更快。

For years there has been an implicit assumption that the economic growth is dependent on emission growth. However, ICT has the potential to reduce energy consumption of almost all other industries. GeSi SMARTer2030 (2015) report1 shows that ICT has the potential to enable a 20% reduction of global CO2 emissions by 2030, thus holding emissions at 2015 levels, and demonstrating that judicious usage of ICT could effectively decouple economic growth from emissions growt.
多年来,人们一直有一个隐含的假设,即经济增长依赖于排放增长。然而,信息通信技术有潜力减少几乎所有其他行业的能源消耗。GeSi SMARTer2030(2015)报告1显示,到2030年,信息通信技术有可能使全球二氧化碳排放量减少20%,从而将排放量保持在2015年的水平,并表明明智地使用信息通信技术可以有效地将经济增长与排放增长脱钩。

The rising prevalence of phone fraud is hurting consumers and businesses. With about a half million reports each year in the United States, phone fraud complaints have more than doubled since 2013. In the current calling line identification presentation scheme, the caller ID is trivially spoofed. Scammers are using spoofed caller IDs to trick their victims into answering unwanted calls and further a variety of scams. To provide a solution to this problem, this paper proposes an authentication scheme that provides the possibility of a security indicator for the current Q.731.3 calling line identification presentation supplementary service. The goal of this proposal is to help prevent users from falling victim to phone impersonation scams, as well as provide a foundation for future defenses to stop unwanted calls based on the caller ID information. This work will help to guide the future development of a standardized scheme in authenticating SS7 identities.
日益猖獗的电话诈骗正在伤害消费者和企业。自2013年以来,美国每年约有50万起电话欺诈投诉,增加了一倍多。在当前的主叫线路标识显示方案中,主叫标识被简单地欺骗。诈骗者使用伪造的来电显示来欺骗受害者接听不想要的电话,并进一步实施各种骗局。为了解决这一问题,本文提出了一种认证方案,为目前Q.731.3主叫线路标识显示补充业务提供了安全指标的可能性。该提案的目标是帮助防止用户成为电话冒充骗局的受害者,并为未来的防御提供基础,以阻止基于来电显示信息的不必要的电话。这项工作将有助于指导SS7身份认证标准化方案的未来发展。

Maldives, Myanmar, and the Philippines are vulnerable to natural disasters [1]. Sendai Framework1 of Action calls for risk reduction by implementing early warning systems [2]. A prevailing challenge is for authorities to coordinate warnings across disparate communication systems and autonomous organizations [3]. Cross-Agency Situational-Awareness platforms and the ITU-T X.1303 Common Alerting Protocol (CAP)2 interoperable data standards presents themselves as solution for diluting the inter-agency rivalries and interconnection disparities [4]. The Sahana Alerting and Messaging Broker (SAMBRO) was designed to overcome these issues by providing a Common Operating Picture and a platform for all Stakeholders to share early warnings. To that end, the CAP-on-a-MAP project is implementing SAMBRO and the CAP standard along with the policies and procedures in the Maldives, Myanmar and Philippines. The project is applying an agile development methodology with a design, build, test, and redesign strategy for implementing the cross-agency situational-awareness and warning system in the respective countries. This paper discusses the country context implementation challenges and discusses strategies fostered through the introduction of the CAP content standard for warning system designers to consider for overcoming similar challenges.
马尔代夫、缅甸和菲律宾容易受到自然灾害的影响。《仙台行动框架》呼吁通过实施预警系统来减少风险。当局面临的一个主要挑战是协调不同通信系统和自治组织之间的警报。跨机构态势感知平台和ITU-T X.1303通用报警协议(CAP)2互操作数据标准本身就是淡化机构间竞争和互联差异的解决方案。萨哈纳警报和消息传递代理(SAMBRO)的设计就是为了克服这些问题,它为所有利益相关者提供了一个共同的操作图和一个共享早期预警的平台。为此,CAP-on-a- map项目正在实施SAMBRO和CAP标准以及马尔代夫、缅甸和菲律宾的政策和程序。该项目采用敏捷开发方法,采用设计、构建、测试和重新设计战略,在各自国家实施跨机构态势感知和预警系统。本文讨论了国家背景下的实施挑战,并讨论了通过引入CAP内容标准促进的战略,供预警系统设计者考虑克服类似挑战。

Adaptive video streaming over HTTP using stochastic bitrate prediction in 4G wireless networks 基于4G无线网络随机比特率预测的HTTP自适应视频流

Video streaming over Hypertext Transfer Protocol (HTTP) used in multifarious applications creating a multimedia environment faces a challenge in 4G wireless network due to the fluctuating nature of internet traffic and variable capacity ofwireless channel over time. The existing Dynamic Adaptive Streaming over HTTP (DASH), though works well for stored video up to some extent, poses a complication in live transmission thereby depreciating the streaming quality due to high link bit rate fluctuation. In this paper, we have proposed an efficient ARIMA Based Bit Rate Adaptation (ABBA) model in the receiver/client side that estimate the link traffic based on the incoming packet bit rate to predict the subsequent future link capacity in order to notify the sender/server. Based on the response from the receiver the server adapt its outgoing stream as per forecasted link data rate, and hence eliminate the degradation of video due to channel throughput variations. The proposed ABBA algorithm was implemented on IP over 4G wireless network and the streaming quality was evaluated on several full reference metrics of video quality. The test result outperformed an existing buffer based approach and also a fuzzy based adaptation algorithm. For example, the ABBA algorithm exhibited an average increase of 22 % in PSNR and 9% in SSIM than a buffer based method.
基于超文本传输协议(HTTP)的视频流用于创建多媒体环境的各种应用中,由于互联网流量的波动性和无线信道容量随时间的变化,在4G无线网络中面临着挑战。现有的基于HTTP的动态自适应流(Dynamic Adaptive Streaming over HTTP, DASH)虽然在一定程度上可以很好地处理存储视频,但由于链路比特率波动大,导致直播传输变得复杂,从而降低了流质量。在本文中,我们提出了一个有效的基于ARIMA比特率自适应(ABBA)的接收端/客户端模型,该模型基于传入数据包的比特率来估计链路流量,以预测后续的未来链路容量,从而通知发送端/服务器。基于接收方的响应,服务器根据预测的链路数据速率调整其传出流,从而消除由于信道吞吐量变化而导致的视频降级。提出的ABBA算法在IP over 4G无线网络上实现,并在几个完整的视频质量参考指标上对流媒体质量进行了评估。测试结果优于现有的基于缓冲区的方法和基于模糊的自适应算法。例如,与基于缓冲区的方法相比,ABBA算法的PSNR平均提高了22%,SSIM平均提高了9%。

Mobile signal extension in deep sea — towards a safe and sustainable fisheries 深海移动信号扩展-迈向安全和可持续渔业
Pub Date : 2016-11-01 DOI: 10.1109/ITU-WT.2016.7805711
Dineshkumar Singh, S. Kimbahune, V. Singh
Despite having one million active fishermen, India lacks a scalable boat-to-shore communication framework. Small boat operators, which form 80% of entire fishing community, are more vulnerable to the wilder nature of the ocean, due to dynamic sea current, wind speed, direction and wave heights, etc. This is also one of reason for fishermen entering accidently in other country's territory, getting caught and sometimes costing their life. This poses a serious question to fishermen and their family, whether they would return the next time they venture out in to the sea. Deep sea mobile connectivity and Information, given in advance about the sea conditions such as wind speed and wave height can help fishermen to plan their trip effectively and avoid the danger zone. This infrastructure could provide path of building "knowledge society" to fishermen deprived of real time and usable information. For realizing this, integration of the existing communication technologies like VHF transceivers, satellite communication and extension of mobile communication network is needed. A consortium of partners like Central Marine Fisheries Research Institute, Tata Consultancy Service and Tata Tele Services piloted a project for mobile signal extension into the sea upto 30kms. This enabled an extended network accessibility, which led to create an Early Warning System over a digital highway of 30 by 120 KM, along the coast. This paper captures the experiences and recommendations derived from this pilot.
尽管印度有100万活跃渔民,但缺乏可扩展的船到岸通信框架。小船操作员占整个渔业社区的80%,由于动态海流、风速、方向和浪高等因素,他们更容易受到海洋野性的影响。这也是渔民意外进入他国领土,被抓,有时丧命的原因之一。这给渔民和他们的家人提出了一个严重的问题,他们下次冒险出海时是否会回来。深海移动连接和预先提供的海况信息,如风速和浪高,可帮助渔民有效规划行程,避开危险区域。这种基础设施可以为缺乏实时可用信息的渔民提供建设“知识社会”的途径。为了实现这一目标,需要整合VHF收发机、卫星通信和移动通信网络扩展等现有通信技术。一个由中央海洋渔业研究所、塔塔咨询服务公司和塔塔电信服务公司等合作伙伴组成的联盟,试点了一个将移动信号扩展到海上30公里的项目。这使得网络的可访问性得以扩展,从而在沿海30乘120公里的数字高速公路上创建了一个早期预警系统。本文总结了该试点项目的经验和建议。

Small boat operators, which form 80% of entire fishing community, are more vulnerable to the wilder nature of the ocean, due to dynamic sea current, wind speed, direction and wave heights, etc. This is also one of reason for fishermen entering accidently in other country's territory, getting caught and sometimes costing their life. This poses a serious question to fishermen and their family, whether they would return the next time they venture out in to the sea. Deep sea mobile connectivity and Information, given in advance about the sea conditions such as wind speed and wave height can help fishermen to plan their trip effectively and avoid the danger zone. This infrastructure could provide path of building \"knowledge society\" to fishermen deprived of real time and usable information. For realizing this, integration of the existing communication technologies like VHF transceivers, satellite communication and extension of mobile communication network is needed. A consortium of partners like Central Marine Fisheries Research Institute, Tata Consultancy Service and Tata Tele Services piloted a project for mobile signal extension into the sea upto 30kms. This enabled an extended network accessibility, which led to create an Early Warning System over a digital highway of 30 by 120 KM, along the coast.

This paper deals with the challenges posed to human safety in the emerging IoT and ubiquitous network scenario by super intelligent machines/cognitive robotics that would coexist in the upcoming heterogeneous world comprising humans and super intelligent machines. Questions of trust in the super intelligent machines have been raised by scientists, sociologists, industry stalwarts, etc. After deliberating on the issues, aligning AI to human interests has been suggested as a plausible option. Agenda for further action proposed is that the ITU may constitute a multidisciplinary umbrella group, collaborating with existing technical and policy groups working on AI standards at technology and policy levels, for in-depth study of all facets, bridging the technology innovations and the policy considerations, and bring out Guidelines for AI aligning with human interests adhering to ethical code.
本文讨论了在即将到来的由人类和超级智能机器组成的异构世界中,超级智能机器/认知机器人将共存于新兴的物联网和泛在网络场景中对人类安全构成的挑战。科学家、社会学家、行业中坚分子等都提出了对超级智能机器的信任问题。在讨论这些问题后,将人工智能与人类的利益结合起来被认为是一个合理的选择。拟议的进一步行动议程是,国际电联可组成一个多学科伞型小组,与在技术和政策层面制定人工智能标准的现有技术和政策小组合作,深入研究所有方面,将技术创新和政策考虑联系起来,并提出符合人类利益的人工智能准则,遵守道德准则。
