摘要
数字电视系统设备的MPEG-2视频码流传输接口主要有ASI和SPI。复用器、QAM调制器、数字卫星综合解码器等一般采用ASI接口输入/输出信号。本文分别采用CPLD和FPGA技术设计符合DVB标准的ASI接口电路。通过灵活配置解码器的ASI输入/输出接口,以扩展综合解码器的功能和应用。
The main MPEG-2 TS interface about digital television system device is ASI and SPI. Multiplexer, QAM modulator and digital satellite integrated decoder usually input or output signal by ASI interface. The paper designs DVB standard ASI inter-face by CPLD and FPGA. The function and application of integrated decoder has been extended through flexible configuration of decoder＇s ASI input and output interface.
