Research, Based On Digital Satellite Tv Receivers In Emma2l

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.
