| 摘 要： | 详细介绍了数据广播协议栈架构及OC协议在架构中的位置，论述了如何采用DVB-C协议中的OC协议等对数据进行分割以便在信道中传输。针对传统有线电视网络，提出了在接收终端对数据进行解析的软件方案，实现了在数字机顶盒中对cable中传输的数据服务信息进行抽取、解析的功能。该方案已通过嵌入式系统及软件的具体实施，证明是切实可行的。

| Abstract: | The frame of data broadcasting protocol and the position of OC protocol in the frame were presented. The technique of partitioning data for translating in channel by using OC protocol in DVB-C is studied. In addition, for the traditional CATV system, a software solution is proposed to parse data in the receiving system. By using the software, the digital Set Top Box （STB） can carry out extracting and parsing information of service data being transmitted in cable. After being applied in embedded system, this solution has been certified to be feasible. |
