摘要 1.引言并行数据广播(简称并播)是传统数据广播的一种特殊形式,即大量的由信息内容提供者(ICP)提供的文化信息并行播出与下载.并播的思想渊源于大规模并行处理技术MPP,其各子系统运作是独立的、无关的,其结果是关联的、可整合的.传统的数据广播大多也带有并行的性质,通常为4路到16路的子信道固定分配方式,因此其"并行度"不高.我们讨论的大规模并行广播,突出的特点体现在具有大规模的并行程度,即高并行度的概念. The Parallel Data Broadcasting Technology (PDBT) improves the Custom Data Broadcasting which is becoming a kind of culture media that is published and released rapidly now. This paper studies the system design and the application of PDBT and then discusses its thought and method. We think PDBT will activate a new manner of information shared and a revolution of super publishing technology.
