Study And Implementation Of The Interactive System Between Terminal And Online Multimedia Resources

With the rapid development of internet broadband technology and multimedia informationtechnology, applications of network technology have become an important part of internetapplications. As the functions of handhold terminals and the release ways of internet multimediaresources have become more various, more and more people choose to get real-time informationby phone. Therefore, the development of handset-based network multimedia resources-on-demandsystem has drawn increasing attention by many people and has become a hot research domain.This thesis, focusing on music on-demand realization based on streaming media technologywith other supporting wireless data functions, discusses a set of non-smart mobile phone dataservice software based on HTTP transport protocol from the prospects of resource releasing modesfrom the server, the wireless network connection, data transmission and matching and so on. Thehardware used are a MT6225 chip and a RISC processer with a ARM7E scanning tunnelingmicroscope, clocking 104M Hz. Adopting MTK08 operating system, through HTTP protocol totransmit music and text files, this software employs amr standard to realize music decoding andprovides users the functions of play online and phone book synchronization. This software worksexcellently on the platform of non-smart mobile phone, and also supports screen touching andkeyboard operation with low cost, which solves the problem of the shortage of multimedia dataservice software based on non-smart mobile phone at present.At first, this thesis discusses the releasing modes of the web server and proposes the hottestcloud computing method for releasing. Then some common network topology algorithms arediscussed by way of comparing the performance index of each method and a topological algorithmwhich is the most appropriate method for cloud computing model is put forward.Then, the achievement of the network connectivity between the mobile phone and the serveris explained in detail, in which a proactive redirection mechanism is put up for the resolution of thedata loss and request failure appearing in the network connecting process. What's more, a newbuffer pool in series model is proposed for the transmission and reception of music data stream,which effectively solves the problem of the memory limitation of non-smart mobile phoneplatform and the instable transmitting rate of wireless data, which at last smoothes the realization ofmusic on demand. As to the data matching in the phone book synchronization module, some common data matching algorithms are compared comprehensively to find out the most suitablematching algorithm for mobile phones.Finally, a debugging platform is established according to the embedded development processand the software is migrated into the sub-module in the mobile phone for testing of each indicator.The results exhibit that the expected goals are achieved.
