Materiality and family consumption: the role of the television in changing mealtime rituals

This interpretivist study contributes to our understanding of how materiality mediates everyday family life by exploring the role of material objects in changing family rituals. We show how the television acts as an agent of cultural change when intermixed with family mealtimes. Our findings present a conceptual framework to explain the ways in which family life is altering across four key areas, namely: (1) mealtime settings and practices; (2) type of food consumed; (3) family structure and membership; and (4) family values and identity. This analytical framework illustrates how technologies such as the television mediate family relationships and how technologies become progressively more embedded in everyday practices. Revealing a transfer of mealtime practices from the formal environment into the informal environment, and vice versa, our study shows how mealtime rituals are altered and changed in form when mediated by the television, but not ultimately abandoned.     

基于“钻石模型”的中国电视娱乐产业竞争力研究

电视娱乐产业是文化产业的重要组成部分,其强劲的发展势头和巨大的经济潜力已经为世界上所有国家认同。现阶段,中国电视娱乐产业的发展尚不完善,产业的各个环节中仍存在许多问题。文章从管理学的"竞争战略理论"角度,运用迈克尔·波特的"钻石模型",对我国娱乐产业的国际竞争力进行了评估,并与韩国的电视娱乐产业进行对比,得出了一套合理提升我国电视娱乐产业竞争力的对策。     

如何做好民族地区广播电视民生新闻的报道

浅谈电视编辑的镜头组接

电视编辑的思维方式与规律直接影响着最终电视作品的质量。前期制作是一种感情创作,而后期编辑则是理智的思维创造。后期编辑决不是简单地堆砌镜头,而是在赋予荧屏以认知和审美的魅力。     

Non-discrimination rules for ISPs and vertical integration: Lessons from cable television

The experience of cable television indicates that vertically integrated ISPs have plausible incentives to favor their affiliated content and to restrict entry of nascent rival content services, but these incentives are weakened in some respects, and strengthened in others, by differences in the economic architectures of cable and Internet broadband. Non-discrimination regulations designed to control such behavior are potentially more effective than in cable, but rules governing discrimination both in the upstream access and the downstream retail markets (as the FCC's no-unreasonable-discrimination rule appears to do) are likely to be necessary for effectiveness. Beneficial effects of vertical integration on financing and entry of cable programming networks should also apply to Internet video content development, but emergence since the 1970s of a robust programming supply industry with few vertical ties to cable suggests that such benefits will be less significant in the ISP case. Finally, the history of both the cable and ISP industries makes evident that the fundamental policy concern should not be vertical integration but horizontal market shares of ISPs, both at the local and national levels.     

一种适合国标DTMB系统的载波恢复新方法

针对数字电视地面多媒体广播（DTMB）接收机中多数传统载波恢 复算法估计范围较小,且没有考虑定时误差的影响,提出了一种粗偏调整结合扫频的低复杂 度载波恢复算法。该算法兼容不同的发送制式以降低接收端的实现复杂度。为了保证估计性 能,算法先利用PN的时域特性进行粗频偏调整,然后用变步长扫频估计剩余大频偏。理论分 析和计算机仿真表明：所提算法抗噪声、多径的能力较强,且对定时估计误差不敏感。     

基于FTV的改进深度估计算法

深度估计是任意视点电视(Free View Television,FTV)系统的关键技术。为提高深 度边缘的深度估计准确度,并解决视频序列中不同帧间同一深度物体深度估计值不一致问题 ,提出一种在深度图的时间一致性保持算法,以前一帧的深度图与当前视图的运动信息为约 束条件估计当前帧的深度,使得相邻帧的深度图在时间上保持一致。     

有线数字电视的网络管理和实施

随着社会和科技的发展,有线电视也开始从模拟电视走向数字电视,因此,在有线电视网络中开展数字电视业务,正是很多专家学者研究的课题。文章先阐述了数字电视技术,然后介绍了有线电视网络的特殊性,最后对网络管理技术在有线电视网络中的应用进行了探讨。     

河北省地面数字电视广播多频网频率规划研究

地面无线电视数字化是未来广播电视的主要发展方向,而地面数字电视广播频率规划方案是顺利开展此项工作的基础和前提,结合河北省地面数字电视广播频率规划研究工作的开展,通过县级多频网规划实例,对地面数字电视频率规划的原则与规划步骤进行了总结,对频率规划所涉及的系统参数和最低接收场强等进行了重点分析,提出了地面数字电视频率规划中县级多频网的一般规划方法,此次制定的方案已经成为河北省建设地面数字电视覆盖网络的基本依据,规划工作的步骤及方法也可为其他地区开展频率规划提供借鉴和参考。     

How advertising literacy training affect children's responses to television commercials versus advergames

This study examined children's advertising literacy level for traditional versus embedded advertising formats by comparing their cognitive and affective advertising literacy level for television commercials vs. advergames. The study also explored how cognitive and affective advertising literacy further attenuate advertising effects by investigating the mediation impact of cognitive and affective advertising literacy on the relation between the ad's format and the purchase request. Third, the study investigated how an advertising literacy training session moderates these effects.

The results of this experimental study showed that advergames lead to a higher purchase request rate among children than television commercials. However, only affective but not cognitive advertising literacy mediated the effect of the advertising format on purchase request. In addition, a training session was shown to accelerate children's cognitive (but not their affective) advertising literacy for advergames, but not for television commercials.
