Based On Ieee1394 Multimedia System

Recently, the demand for dealing with high capacity multimedia data such as video streams in the home has grown through the spread of high-performance Personal Computers(PCs) and through the expansion of digital Audio/Visual(AV) consumer equipment and digital broadcasting. PC networks are already beginning to be constructed in homes through the explosive spread of the Internet. Against this background, the fusion of PCs and AV equipment together with other home equipment is attracting much attention as a major topic which can bring great benefits to the industrial world. As far as the present technology is concerned, there are not any technology which can include all the equipment above. However, there are some technology that can play a part in this area, such as USB, IrDA, wireless networks IEEE1394, Ethernet and RS232 etc. Among these technologies, the high-performance serial bus IEEE1394, is a highly promising solution as an infrastructure which can support the trends, because of its superior features, including high speed, guaranteed bandwidth, plug and play, hot plug, slim cable and flat hierarchy.This thesis mainly shows the implementation mechanism of the real-time camcorder application system based on IEEE1394. This thesis does research on the architecture and implementation method of the protocol stack of IEEE1394, and analyses the feature of Digital Video. Based on these, this paper gives the solution of transferring Digital Video over IEEE 1394 serial bus and the method of decoding Digital Video. Furthermore, at the end of this paper it also explores the solution of utilizing IEEE 1394 to construct home networks.The paper is divided into several chapters as follows:The first chapter shows the background of IEEE 1394 and the present research status of IEEE1394 high-performance serial bus.The second chapter mainly explains the protocol stack of IEEE 1394 from several aspects including basic function, system architecture and logic units and so on.In chapter 3, I describe the principle of Digital Video and the relationship withIEEE 1394.Then comes the forth chapter, which is the main body of the thesis. In this chapter, I pay every effort to describe how to implement the camcorder application system based on 1EEE1394 serial bus protocol stack. To make it neat and easy to be understand, I separate the system into several modules: libraw 1394 module, raw1394 module, ieee 1394 module, capture Digital Video module, decoding video module anddecoding audio module.In the last chaPtOf, I exPlore the tCchnology of IP over IEEEl394, explain thesoluhon mechanism of consmicting home networks with IEEEl394 and point out theaPPlication fuwt of IEEEl394 home netWrks.
