摘　　要：针对串行数字接口(SDI),提出了一种基于FPGA的音频数据IP模块解嵌方案。介绍了相关协议标准,重点介绍了音频解嵌IP模块的内核架构与设计过程,并给出了一个基于本IP模块的SDI音频解嵌系统应用实例。实践证明基于本IP模块的音频数据解嵌方案能有效地从SDI数据流中解嵌出音频数据,实现音、视频同步;并且本IP模块具有很强的通用性和可移植性,能提高设计效率,降低产品成本。Specific to serial digital interface, this paper advanced a scheme of audio demuhiplexing intellectual property module based on FPGA. After explaining the related standard protocols, the kernel architecture of audio demuhiplexing IP module and design processing were introduced in detail. Finally, this paper gives an application of audio demuhiplexing system based on IP module in serial digital interface. It is shown through the experimental results that the scheme of audio demuhiplexing IP module could effectively demuhiplex audio data from SDI data stream and achieve synchronization about audio and video. The IP module was provided with universality and portability, which could improve design efficiency and cost reduction.
