Design Of Car Audio

China auto market, production and sales increased year after year, by 2010, will reach 10 million more than Germany, Japan. the second largest auto production and consumption.The global upsurge of car buying and selling began to shift to the Chinese market..China car audio market 2005, total sales of car audio products in China about 50 billion yuan, an increase of 20%.According to estimation, China car audio and video product sales within the next few years will be growth rate is changing China car audio market. The next few years, the total domestic demand for cars will be a more balanced pace, and this is a long process, with industry experts predict that in the next few years, China's auto industry will still be 15% of the speed of development, while China car audio market with the overall automobile market steadily. And in the future development of the automotive market, car audio and navigation entertainment system will become mainstream configuration products, and will also affect the future development of China automobiles.Audio and video market consumer demand tends to practical, persona car audio and video products continue to strengthenfunctions. car audio and video products have been integrated GPS navigation, DVD entertainment, ensor + reverse assistance systems, intelligent trajectory reversing system, car computers, and Bluetooth and other . This is also car audio and video pre-installed market, especially. With the rise of China auto industry, automotive multimedia related technology also flourished. Thecurrentmedia focus on caraudio-visualtechnology. DVD technology matured,bring represents the current direction of car audio industryUnder this environment, personallization development has become a major trend, including the following content: no CD disc in the CD to determine the function from read information; CD disc into rewind function in CD mode; fast forward function pause; as well as HI-TEMP ERROR, CD ERROR, MACH ERROR.This system uses the DVD processor and host CPU TMP87CH47U ES60X8 as the main component, to achieve CD, VCD, MP3, DVD and other formats of audio playback. ES60X8 Series DVD processor is company's products, which includes two parallel processing units, a RISC processor, a vector engine, and additional hardware resources to perform specific encoding / decoding tasks. These resources two separate data bus. ES60X8 built-in video DAC, video encoding,output analog video signals to simplify the external circuit. Servo circuit read out the data by ES60X8 direct output analog video signals and digital audio signals; ES60X8 EPROM program / data external memory SDRAM as the display memory. As ES60X8 all audio / video signal master CPU does not need address / data bus, so the master CPU only ES60X8,LCD display panel.
