伴随经济社会不断向前发展,广播电视媒体逐渐渗透到公众日常生活的方方面面,日益影响着公众的精神文化生活。传统的广播电视媒体已经不能满足新时代发展需求,信息瞬息万变,公众对于信息接收方面的需求量越来越大。对于广播电视工程而言,应当主动借鉴和应用计算机互联网等技术,加强技术融合,从而更好地为公众服务。本文在对计算机技术基本内涵、重要性进行分析的基础上,对计算机技术在广播电视工程中的应用途径及保障措施进行了论述,以期为推动计算机技术与广播电视工程深度融合等领域研究探索提供一些帮助。 相似文献

日前,三网融合试点方案正式通过,国家就三网融合中广播电视系统和电信系统各自的职责范围进行了明确,整体来看,三网融合中最为关键的IPTV集成播控平台的建设和管理权被确定为广电独有。同时内容规定:符合条件的广播电视企业,可以经营增值电信业务和部分基础电信业务、互联网业务;符合条件的电信企业,可以从事部分广播电视节目生产制作和传输,鼓励广电企业和电信企业加强合作、优势互补、共同发展。那么,这一方案的出台对广电和电信产生怎样影响,电信又该如何面对。 相似文献

This article describes the rationale for the multiphase creative problem solving process, and reports the findings from an empirical investigation conducted to facilitate the problem solving of managers. The ideational skills of the managers were assessed before and after training in a complete process of creative problem solving, along with their ideational attitudes, creative problem solving style (i.e., generator, conceptualizer, optimizer, or implementor), and evaluative skill (i.e., ability to recognize original ideas). The most important findings indicated that the training had a significant impact on the evaluative accuracy of the managers. They were significantly more accurate in their judgments about original ideas after training, both in their identification of original ideas and their recognition of unoriginal ideas. After training, the managers also gave more solutions and more original solutions to problems. Finally, several variables (e.g., the “preference for active divergence” attitude, and the conceptualizer process style) seemed to moderate the impact of training. Training was therefore effective, with specific effects that can be predicted from pre-training individual differences in attitudes and process style. 相似文献

The deep connection between the Burrows–Wheeler transform (BWT) and the so-called rank and select data structures for symbol sequences is the basis of most successful approaches to compressed text indexing. Rank of a symbol at a given position equals the number of times the symbol appears in the corresponding prefix of the sequence. Select is the inverse, retrieving the positions of the symbol occurrences. It has been shown that improvements to rank/select algorithms, in combination with the BWT, turn into improved compressed text indexes. 相似文献

A new method of stochastic model reduction has recently been introduced by Desai et al. [1], [2]. The stability of the reduced order model has not previously, been considered. In this paper, we show that the stability of the reduced order model follows directly from the results of Pernebo and Silverman [3]. It is also shown that the reduced order model is minimal, in the controllability/observability sense. The relevance of this notion of minimality to stochastic minimality is made clear. 相似文献
