摘要： 针对播存网格，对节目进行统一内容定位(UCL)标引，将UCL信息封装进IP包，形成用于传输的广播IP(BIP)包。设计一种基于UCL的BIP包硬件过滤系统。模拟广播网的数据传输过程，在源端对节目进行UCL标引得到BIP包，以太网终端通过现场可编程门阵列在数据链路层对BIP包进行解析和过滤，并将结果交付用户存储。实验结果验证了该系统的有效性。

Abstract: Aiming at broadcast-storage grid, this paper indexes the programs based on Uniform Content Location(UCL), and transmits the Broadcasting IP(BIP) packets comprised of IP packets which is contained of UCL information. It presents a hardware filtering system based on UCL for BIP packet. The transmission process of broadcasting network is simulated, and the BIP packets are formed through UCL indexing in source side. In Ethernet terminal, the BIP packets are resolved and filtered in the data link layer by Field Programmable Gate Array(FPGA). The results are delivered to user to store. Experimental results demonstrate the effectiveness of this system.

Key words: broadcast-storage grid, Uniform Content Location(UCL), hardware filtering, Content Addressable Memory(CAM)
