Abstract 818: Fighting prostate cancer with a multimedia approach

Abstract Introduction: Black men have the highest prostate cancer (CaP) mortality rates. The reason for this disparity is multifaceted, including the barriers that they face at the individual, provider, and health system levels. To address these challenges the iCCaRE for Black Men Consortium uses a multi-level approach to disseminating CaP information. This approach is rooted in research which shows that Black men prefer to receive information through multi-media channels tailored to their needs. In addition, studies have reported that CaP survivors were viewed as credible sources of information. This presentation reports on how iCCaRE Consortium is bridging the digital divide in minoritized communities to disseminate CaP information in a way that is meaningful to the community. Methodology: iCCaRE uses a multimedia method to reach Black men. This includes twitter post, Facebook, YouTube, ecancer and community lunch and learns. In addition to social media, we have partnered with LitTV Network, a locally owned digital TV platform, on which we have iCCaRE TV. On Lit TV network we have the ability to reach 11,000 homes in our catchment area. Furthermore, the consortium has produced informational flyers that are disseminated at outreach events and at the American Legion Post 197. On the twitter page the consortium post: (1) 2 scientific publications per day authored by members of the consortium, (2) 2 weekly “Did You Know” facts about prostate cancer with sources attached, (3) 2 weekly url post sharing a link to a video from the iCCaRE consortium YouTube page and (4) clips of CaP survivors sharing their experiences. On the YouTube page we currently have: videos series of a CaP survivor who is also a physician scientist, interview series with MPIs and members of the consortium, CaP survivor series including a barbershop interview with a survivor. Results: The iCCaRE Consortium multimedia efforts have a global reach, in less than a year we have gained 102 twitter followers. On average the twitter page receives 8,700 impressions during the CaP awareness month in September the twitter page garnered over 14,000 impressions. Our videos on the ecancer platform have a combined global view of 341 representing countries such as the United States, Nigeria, Cameroon, United Kingdom, Macedonia, and Mexico. The American Legion Post 197 in North Jacksonville has served a cumulative of 229 people through outreach and educational event called lunch and learns. Our YouTube channel has had almost 100 views in its first month of being active. Conclusion: Using a multi-level approach to reduce the burden of CaP for Black men is vitally important; without such efforts the disparate thread in mortality will continue to persist. Meeting Black men through the mediums they use for gathering health information removes barriers, increases access and will aid in the fight against CaP for Black Men.

An approach to generate and embed sign language video tracks into multimedia contents

Deaf people have serious problems to access information due to their inherent difficulties to deal with spoken and written languages. This work tries to address this problem by proposing a solution for automatic generation and insertion of sign language video tracks into captioned digital multimedia content. Our solution can process a subtitle stream and generate the sign language track in real-time. Furthermore, it has a set of mechanisms that exploit human computation to generate and maintain their linguistic constructions. The solution was instantiated for the Digital TV, Web and Digital Cinema platforms and evaluated through a set of experiments with deaf users.

Hybrid compilation and optimization for java-based digital TV platforms

The Java-based software platform for interactive digital TV (DTV) is composed of the system/middleware class statically installed on the DTV set-top box and the xlet applications dynamically downloaded from the TV stations. The xlet application includes Java classes and image/text files. The xlets are executed only when the TV viewer initiates an interaction, even if the xlets have been completely downloaded. To achieve high performance on this dual-component, user-initiated system, existing just-in-time (JIT) compilation and optimization is not enough; instead, ahead-of-time and idle-time compilation and optimization are also needed, requiring a hybrid compilation and optimization environment. We constructed such a hybrid environment for a commercial DTV software platform and evaluated it using real, on-air xlet applications. Our experimental results show that the proposed hybrid environment can improve the DTV Java performance by more than three times, compared to the JIT-only environment, with little change to other DTV behavior.

디지털 TV 시청 행태에 부합하는 데이터 서비스 기획 가이드라인

거실 엔터테인먼트의 핵심 플랫폼인 TV는 사용자층의 다양성과 브랜드 이미지 제고의 장점을 갖고 있기 때문에 기존 인터넷 서비스 업체들이 자사의 서비스를 디지털 TV의 데이터 서비스로 구현하여 서비스 고객의 층의 확대와 서비스 브랜드의 제고를 꾀하고 있다. 그러나 대부분의 데이터 서비스들이 시청자의 한정적인 시간을 대상으로 방송 영상 콘텐츠와 경쟁하는 구도를 취하고 있어서 성공적인 효과를 거두지 못하고 있다. 본 논문은 방송 영상 콘텐츠 시청이 TV의 주된 활용 목적인 시청자의 TV 시청 행태를 고려한 데이터 서비스의 기획 가이드라인을 제시하고 PC 기반의 인터넷 미팅 서비스를 디지털 TV로 확장하고자 하는 모 기업의 데이터 서비스를 가이드라인의 사례로 소개한다. As a digital TV has outstanding features of being the most influential device in the living room and having the wide spectrum of users, several internet services has been ported on the digital TV platform (in the form of data services) in order to enhance their brand powers. Most of the services, however, failed to get a satisfactory results as the data services are defeated by the broadcasting contents in the competition for the viewer's interests. In the paper, the design guidelines that make data services not to compete with the broadcasting contents are proposed and a prototype of a data service that accommodates the guidelines is introduced.

Broadband Content Services: Intellectual Property Rights at War with Convergence?

The Directive on the coordination of certain rules concerning copyright and rights related to copyright applicable to satellite broadcasting and cable retransmission, did not achieve its goals. Market fragmentation still continues, the facultative mediation procedure failed and the system of extended collective license is put into question. The Directive does no longer fit in an era of (interactive) digital television and convergence of networks, services and consumer devices. New broadband content services through the internet and digital tv-platforms must be interpreted within the new legal framework of the Directive on the harmonization of certain aspects of copyright and related rights in the information society. This seems to cause new problems again. The current regulation for cable retransmission has to be revised or replaced by a technologically neutral retransmission right. For a genuine European market for audiovisual services to emerge, a one stop shop system should also be installed

Flexible Transport of 3-D Video Over Networks

Three-dimensional (3-D) video is the next natural step in the evolution of digital media technologies. Recent 3-D autostereoscopic displays can display multiview video with up to 200 views. While it is possible to broadcast 3-D stereo video (two views) over digital TV platforms today, streaming over Internet Protocol (IP) provides a more flexible approach for distribution of stereo and free-view 3-D media to home and mobile with different connection bandwidths and different 3-D displays. Here, flexible transport refers to rate-scalable, resolution-scalable, and view-scalable transport over different channels including digital video broadcasting (DVB) and/or IP. In this paper, we first briefly review the state of the art in 3-D video formats, coding methods for different transport options and video formats, IP streaming protocols, and streaming architectures. We then take a look at beyond the state of the art in 3-D video transport research, including asymmetric stereoscopic video streaming, adaptive and peer-to-peer (P2P) streaming of multiview video, view-selective streaming and future directions in broadcast of 3-D media over IP and jointly over DVB and IP.

CPRS: A cloud-based program recommendation system for digital TV platforms

Traditional electronic program guides (EPGs) cannot be used to find popular TV programs. A personalized digital video broadcasting-terrestrial (DVB-T) digital TV program recommendation system is ideal for providing TV program suggestions based on statistics results obtained from analyzing large-scale data. The frequency and duration of the programs that users have watched are collected and weighted by data mining techniques. A large dataset produces results that best represent a viewer’s preferences of TV programs in a specific area. To process such a massive amount of viewer preference data, the bottleneck of scalability and computing power must be removed. In this paper, an architecture for a TV program recommendation system based on cloud computing and a map-reduce framework, the map-reduce version of k -means and the k -nearest neighbor (kNN) algorithm, is introduced and applied. The proposed architecture provides a scalable and powerful backend to support the demand of large-scale data processing for a program recommendation system.

TVGuide2.0: applying the Web2.0 fundamentals to IDTV

In this paper we introduce our experiences in applying the Web 2.0 philosophy to build a TV guide system for Interactive Digital TV (IDTV) platforms. Subscribers give their opinion about TV content and, informally, a folksonomy is progressively built. Based on this shared knowledge, the TV guide obtains personal recommendations and allows users to browse among the multimedia content. Additionally, and over this collaborative layer, a more formal vision enables applying semantic reasoning to supplement the knowledge informally inferred.

The Positioning and Current Situation of China's Digital TV

Digital television research and development started in China in the 1980s. Implementation has been underway over the last decade and the digitalization of the three platforms (cable, terrestrial and satellite) is in progress. Focusing on the strategic positioning of these three digital TV platforms, this article outlines the current situation, including take-up, coverage, service pattern, government support, and the main techniques and then expounds the two problems confronting digital TV in China.

End-user live editing of iTV programmes

Watching TV is a practice many people enjoy and feel comfortable with. While watching a TV programme, users can be offered the opportunity to, while making annotations, create their own edited versions of the programme. In this scenario, it is a challenge to allow the user to add comments in a ubiquitous, transparent way. In this paper, we exploit the concept of end-user live editing of interactive video programmes by detailing an environment where users are able to live edit a video using the iTV remote control. We contextualise our approach in the context of the Brazilian Interactive Digital TV platform.

Los canales temáticos: una alternativa a la programación de la televisión generalista

Last decades of past century, there appeared a double-sided phenomenon. On one hand a crudest competence among general TV networks and therefore, with hardly some exceptions, TVnetworks marginalized cultural programs to the borders of timetable grids. On the other they appeared TV thematic channels devoted to different elements of culture with an aim of high quality products. The broadcast of this internationalist network TV arrive everywhere thanks to digital TV platforms. These new TV networks are in a continuous process of renovation both of searching new content and image. The previous balance in TV broadcast where genres were distinguised and there was a coherent timetable have disappeared. Now the system mixes genres and formats. The economic context also is confusing with the high increase of production costs combined with a policy of downsizing. As a result, cultural approaches have been decreasing in public network TV and previous criteria for culture in TV have been left aside. Thesecultural approaches never existed in private network tv because its principal aim is to achieve the highest share by means of raw products in new formats such as talk-sohw, reality show and lateshow La televisión, desde su nacimiento por los años cincuenta, pretendía ser cultural, utilizaba su monopolio para imponer unos productos con pretensiones culturales y formar los gustos de la audiencia. Además, entre mediados de la década de los 60 y principios de los años 80, tuvo lugar la implantación en el ámbito nacional de la primera generación de canales culturales. BBC-2 (Gran Bretaña), TVE-2 (España), ARD-3 (Alemania), FR-3 (Francia), RAI-3 (Italia). Estos canales son las segundas y terceras señales de los entes públicos de radio y televisión y tendieron a una diversificación de los contenidos programados con un fuerte componente de carácter cultural (música, cine, literatura, artes plásticas, teatro, etc.). Sin embargo, en la última década del pasado siglo se dio un fenómeno de doble dirección. Por un lado, la competencia cada vez más encarnada entre las televisiones generalistas, que, salvo contadas excepciones, relegaron los programas culturales a espacios cada vez más marginales en la parrilla de programación y sin apenas autopromoción en dichas. Por otro, surgieron en distintos países canales temáticos dedicados a diversos aspectos de las culturas y cuyo principal objetivo es la emisión de productos de calidad.Estas señales con carácterinternacional llegan a todos los rincones del planeta a través de las plataformas digitales de televisión de difusión satelital. Son canales que están en continua inquietud por la renovación, tanto en la imagen como en la búsqueda de los mejores contenidos. El equilibrio existente en la programación televisiva donde se separaban los géneros y se delimitaban las franjas horarias ha dado lugar a un sistema donde se proyectan de manera confusa géneros y formatos. Todo ello dentro de un contexto económico bastante dramático de encarecimiento de produccióny de intentos desesperados de reducción de costes. Y el efecto más evidente de lo dicho es que los enfoques culturales han ido menguando en la TV pública olvidando algunos de sus principios, enfoques que nunca existieron en la televisión privada, y esto ha sido debido a la loca carrera por alcanzar una audiencias lo más alta posible, ofreciendo a los telespectadores productos sin refinar, cuyo paradigma son los nuevos formatos surgidos como eltalk-sohw, reality show o lateshow. Y es que hablar de calidad en la televisión no tiene por qué identificarse única y exclusivamente con la emisión de programas culturales como el teatro, música de calidad, el cine, los programas sobre libros, sino también toda una serie de programas divulgativos de carácter social y de servicio público, de investigación científica, folklore, programas documentales en todas sus disciplinas, algunas series que, sin duda, tienen un gran nivel de calidad y además un gran reconocimiento por parte del público, o algunos programas de humor que requieren una buena dosis de creatividad e inteligencia. Incluimos también en este ámbito algunos programas de debate y entrevistas, que tienen un buen planteamiento y, por tanto, pueden servir para la difusión cultural y para la reflexión. Y es que, cuando sereclama una mayor calidad en la televisión, no nos referimos sólo a que existan programas específicamente culturales, sino, en gran medida a que la programación en su conjunto esté impregnada de un mayor nivel cultural.

Multi-channel publishing of interactive multimedia presentations

The ongoing convergence between TV and the Internet leads traditional broadcast companies to publish their content on the Internet. Interactive digital TV platforms, which support rich interactive multimedia applications, are targeted ever more frequently. New consumption platforms of this kind are predominantly built on Internet technologies, yet they have their own specific capabilities and limitations in both technical and presentational sense. Publishing interactive multimedia presentations to these platforms poses significant challenges for the generic description of the presentation content, and for the filters that convert these descriptions into final-form presentations. We present a generic publication framework that features a simple data model and a flexible filter architecture. It enables the conversion of a generic input description into presentations targeted at different consumer platforms. As such, it promotes content reuse across platforms, while allowing platform-specific optimizations. The data model and associated file format provide description language independence, essence abstraction and content reuse at a high semantic level. From this model, a structuring format is derived that can contain any presentation description. The architecture of the publication framework is modular and highly extensible, allowing for new input description languages and final-form presentation formats. We demonstrate the infrastructure by an example scenario in which an interactive weather report is being published onto four different platforms (Web, TV, MHP and WAP).

Digital ready TV platform with synchronization shaping circuit

This paper proposes an improved digital ready TV platform that can support a signal input with various resolutions. Due to the inadequate performance of the built-in digital PLL (phase-locked loop) of an ADC (analog to digital converter) and poor tolerance of ADC ICs, there are problems in the stable processing of synchronization signals with various input signals. Accordingly, the proposed synchronization shaping technique regenerates the horizontal synchronization signal in the vertical blanking interval based on the regularity of the synchronization signal, i.e. the timing of the signal falling edge remains constant, thereby solving the above problem and minimizing the interference of the system. As a result, the proposed system can stabilize various synchronization signals with different resolution modes.
