With the development of network and information, intelligent home has become a trend.Intelligent home mainly to residential as a platform, with the main function of networkcommunication, electrical control, information and entertainment, security and so on, with thehelp of this system, can effectively improve the efficiency of distribution of personal time, life,the protection of personal and property safety. For example, through the video and thesecurity protection system can guarantee the safety of Home Furnishing life; electrical controlcan effectively facilitate personal life; intelligent system can automatically switch to windows,control of air conditioning in the unattended condition, let the owner returned homeimmediately get good quality of the environment, and can be Home Furnishing feedback toindividuals, at any time to Home Furnishing like the palm. Along with the people to the livingenvironment demands, intelligent Home Furnishing Bi Ran has broad prospects.Smart home industry has been developing rapidly in recent years, now has a lot of smarthome products continue to emerge, although has many functions but a lot of functionalmodules are independent existence, and the function is single and the smart home is not acomplete sense of. At present, the domestic and foreign intelligent home has no clear functiondivision, no standard protocol, unified management, no control, linkage of unified standards.So the user using the intelligent Home Furnishing system may face multiple wiring, equippedwith a plurality of remote controllers, switches a plurality of console problems. But with thedevelopment of embedded technology, intelligent Home Furnishing system function will bemore and more complete, perfect, operating system also will more and more convenient, fast.Since the intelligent Home Furnishing system has many sub function modules, but the controlmode, use method of Datong small anomalies, this paper cannot be one one of them, The choice of the most representative video center is more representative of the development ofaudio-visual center, covering the construction of the embedded system hardware platform,software porting, audio and video transmission, hardware control and other technology, widecoverage, covering most of the technology and principle of embedded system, intelligenthome equipment representative the typical.In this paper the selection of hardware platform, through comparative analysis ofdomestic and foreign decoding chip CPU and audio after the final selection of the multimediaplayer can meet the high performance CPU and large dynamic range of the audio decoderchip, and the main chip to match a variety of circuit design and audio components, the finalcompletion of the selection and the process of design and manufacture of peripheral circuitsand electronic components, so that the smart home system has ability and stable operation ofthe audio with large dynamic range, low noise and low, the video can reach1080P resolutionvideo broadcast.The network data transmission process of TCP socket in the software; the use ofanonymous pipes, embedded system Linux named pipe; QT IDE programming tools to thedevelopment of Android mobile phone terminal program and so on, the final completion ofthe development of intelligent Home Furnishing software system.In this paper to show the intelligent Home Furnishing in hardware design process andultimately determine the hardware selection process and the software development processand meet in the process of large amounts of data. Through the research, hope to eventuallydevelop a set of complete functions, perfect the system of home audio-visual center.
