西方公共电视的节目评估:收视率悖论

在经营和编辑上试图独立于政府控制和商业影响的西方公共电视系统在评估节目时面临着使命与效率的冲突。收视率依然是公共电视系统在判定理想节目时的关键指标 ,但是并不是唯一的“指南针” ,各公共电视系统往往是综合使用收视率和收视质的表现评估节目价值。     

Nurturing Authority

When considering the role of local journalism in a networked media environment, it is crucial to examine how audiences attribute news with the power to define social knowledge. In particular, television news programs need to appeal to audiences by reinforcing a sense of local journalistic authority to assert the parameters of who and what is worthy of coverage. This article presents the findings from interviews with a range of commercial television news viewers in Sydney, Australia. It positions viewership in the context of people’s wider engagement with news, and in relation to their interpersonal and digital social interactions. The paper argues that local audiences have conflicting attitudes to the role of television news, both contesting and re-inscribing the programs with the power to demarcate social, political, and cultural knowledge. It traces how local audiences challenge the ability of news to convey boundaries within the community through processes of exclusion, connecting the contestations to the lived experiences of the individuals. It identifies that television news programs nurture journalistic authority in terms of their local relevance, and it contributes insights on the significance of local news by engaging with the means by which audiences themselves attach social power to journalism.

3DV quality model based depth maps for view synthesis in FTV system

Depth maps are used for synthesis virtual view in free-viewpoint television (FTV) systems.When depth maps are derived using existing depth estimation methods,the depth distortions will cause undesirable artifacts in the synthesized views.To solve this problem,a 3D video quality model base depth maps (D-3DV) for virtual view synthesis and depth map coding in the FTV applications is proposed.First,the relationships between distortions in coded depth map and rendered view are derived.Then,a precisely 3DV quali...
