【摘要】 电视台无压缩播放系统是一个多媒体计算机系统,它要求其存储子系统具有大容量、高数传率、高可靠性、高可用性及可扩展性等特点。本文详细分析了这些性能,并在我们自己构建的无压缩播放系统上作了实现与验证。运行结果表明,此存储子系统不仅很好地满足了标准清晰度电视无压缩数字播放系统的要求,而且也可满足高清晰度电视数字播放系统的要求。更多还原

【Abstract】 The uncompressed digital playing system for TV stations is a multimedia computer system. It requires its storage subsystem has a massive capacity, a high transfer rate, good reliability, high availability and scalability. In this paper, these performances are analyzed in detail and are validated on the uncompressed digital playing system built by us. The operation results indicate that the storage subsystem can satisfy not only the demand of the uncompressed digital playing system for SDTV, but also the demand of the digital playing system for HDTV.更多还原
