【摘要】 随着压缩技术的突破和数字视频广播(DVB)标准的产生,数字卫星压缩传播方式已成为卫星传播的主流。由于数字卫星传输方式具有传输效率高,传输质量好、抗干扰性强等优点,数字卫星广播电视技术得到了迅速发展。本文涉及的是数字卫星电视终端系统的软硬件研发,采用NEC公司EMMA架构第二代增强型多媒体处理器,完成了基于EMMA2L的数字卫星电视接收机的设计。本文所作的主要工作如下:进行了数字卫星电视接收机的硬件设计针对EMMA2L研究并开发了JTAG测试程序研究了嵌入式系统的汉字显示技术,在本系统上实现了汉字的动态编码与显示。设计了DiSEqC开关程序及EPG电子节目指南更多还原

【Abstract】 Along with the compress technology breakthrough and the standard creation in digital video broadcast( DVB), the way that the digital satellite compresses to spread has become the main current which the satellite spreads.Because the digital satellite delivers has the efficiency of deliver high, the good quantity, strong in anti-jamming, the digital satellite broadcast television technique got the quick development. What this thesis involve is digital satellite that digital satellite television terminal system of the soft and hardware develops, adopting the NEC company EMMA architecture, the second generation enhanced multi-media architecture processor, completing according to the EMMA2L receive the design of the machine.The main contents are as follows:1.Proceeding the hardware design of the digital satellite receives. 2.Aiming at the EMMA2L research combined to develop the JTAG the test procedure.3.Studied the embedded system about the Chinese manifestation technique, realizes on this system Chinese characters of dynamic code and show.4.Designed DiSEqC switch and EPG electronics program guidebooks procedure.更多还原
