Abstract


With the rapid development of scientific technologies, the concept of "digital family" has been well known currently. The function of entertainment, as the key of the development of that concept, is regarded as the most important aspect by the relative manufacturers nowadays. The family network in the future probably covers the fields of the sharing of interior resources, the lodging of Internet, IPTV, the order programming of audio and video, instant communication and other applications unknown at present.This dissertation, based on the design of HHARM2410 of Huaheng Corporation, carries out its illustration on the realization of demonstrative system of network acoustics. The main contributions are as follows:1. The construction of the software flat of network acoustics is investigated.2. The design of network acoustics system is presented, including its construction and operation.3. The general design of the system, mainly covering that of software, is well illustrated.4. The software system of network acoustics is designed and realized. According to different functions, the software is divided into three modules-the module of audio decoding and broadcasting, the module of network transmission and the module of interface control. Based on the description of its general design, the three modules are presented in detail respectively. The MiniGUI is chosen as the GUI supporting flat.During the actual demonstration, the system is bound to suffice the requests, which call for the function of downloading, decoding and broadcasting the needed MP3 resources from the simulative server in the local area network (LAN) by FTP.The combination of embedded system and digital family developes many new applications, the network acoustics based on Linux is bound to play an important role in the digital family.
