摘要
介绍了一种基于AVS解码芯片DS1000的IPTV机顶盒的设计和实现。硬件方面结合Broadcom公司IPTV专用处理器进行音频解码和电视信号的输出处理。软件方面采用嵌入式Linux操作系统,底层采用基于字符设备的驱动支持,遵循DS1000的解码处理流程可以高效流畅地的实现AVS流媒体的直播解码和良好的用户界面。
The design and realization of an IPTV STB based on AVS decoding chip DS1000 is proposed. In hardware design, the special IPTV processor is used to process the decoding audio signal and output TV signal. In the software design, the embedded Linux operation system is used, and the drivers based on the character device are adopted on the basic layer. Meanwhile, the special decoding processing steps of DS1000 make the decoding of AVS streaming media broadcasting more efficiently and fluently amd make user interface much friendly.
