摘要
在详细分析MPEG-2和DVB标准支持数据广播机制的基础上,讨论了如何在DVB兼容接收机中设计实现数据广播的接收。把解复用以后广播数据的处理分为两个步骤:去包装和应用解释。去包装过程被抽象为数据过滤器,并以多协议封装方式为例说明了过滤器的设计。
The mechanism of MPEG-2and DVB supporting data broadcasting is analyzed carefully at the be-ginning,and then a general method is presented for receiving data in DVB compliant digital television receivor.The process of the broadcasting data after demultiplex is composed of two steps:deencapsulation and applicant ex-plaination.The deencapsulation can be visioned as data filter and demonstrate the device of the filter by taking multiprotocol encapsulation as an example.[
