Abstract


With development of laser disc, DVD can not merely limit to play standard definition video disk. HDTV has already entered ordinary consumption families, the future audio-visual trend MPEG-4 and very popular network film format of Divx has become the amusement theme. Integrating more functions is imperative for the development of DVD.In this paper, Phoenix ES8380 processor of ESS Company is used as DVD core process chip to drive IC, SDRAM, Flash-rom memory, audio DAC digital-to-analogue conversion circuit, ect. They constitute a DVD player system which is divided into servo control part and AV audio and video decoding part according to function. The high-speed transmission of the data between the two parts is realized by ATAPI interface. The paper includes four respects:ES8380 single chip’s servo system, ES8380 single chip decoding system, ES8380 single chip application circuit and system test and evaluation.This system has realized the goal of the following:(1) Design of a servo system supporting many kinds of video disc formats, servo signal error correcting and coding/decoding.(2) Design of a audio/video system, multichannel audio output and HDMI output.(3) Design of audio/video circuit, mute circuit and starting circuit, reaching all audio/video target requirements.(4)System reliability design. Making this system can work under high/low temperature and high humidity conditions.Based on ES8380 chip system, the servo and decoding chips are replaced by one chip. This accelerates the engine, promotes system decoding speed and efficiency, and accelerates the operation speed by 10 times, which makes audio/video display more smooth and nature. The DVD chip system does well in testing. It can support many kinds of code formats, realize USB functions, etc., and other electric indexes have reached the design requirements.
