Embedded Multimedia Digital Entertainment Devices, And Implementation

With the development of the technologies in microprocessor, DSP, multimediacoded, embbeded systems, multimedia entertainment terminal has been very popular inconsumer electronics design. Moreover, with the mature of Mp3 technology and theinitial delopment of Mp4, digitial TV and 3G telecommunication applications, we canexpect the fast development of multimedia entertainment terminal in the next a fewyears. In the eleventh five-year plan for national economic and social development,digital audio&video information industry has been in the top priority to be invested.The single functioned music players have been out of date and were elimited fromthe market because they cannot meet the higher and higher expections to the multimediafrom end users. The progress in multimedia SoC technology has enabled that embbededsystem can realize multiple types of multimedia applications based on a single SoC.How to use the SoC to design a product as soon as possible and what is thecommonness of those systems is the critical problem cared by many engineers.This dissertation firstly analyses some relative technology in multimediaentertainment terminal field. Then, it makes references to some popular products. At last,it comes out an example design based on SoC STMP3660. This product has manyfeatures all in one: audio playing, video playing, FM listening, txt ebook reading,recording, games, picture viewing. This dissertation is mainly about the example designand its implementation, while putting the theory research in the second place. Thetheory research and experience about quick design of multimedia product in thisdissertation could be reused as a help.The outline is here:1. Analysing some multimedia entertainment terminal design technology, withexpansion on development of the same kind of system.2. Discoursing some platform relative features, design thinkingness and systemarchitecture.3. Specifing the concrete example, including the work flow, detailed design and datastructure. 4. Discussing the product testing method, testing tools and testing results.5. Summary report. Pointing out the advantages, disadvantages and the way toimprove.
