The Software Research Of The Mobile Electronic Seeing And Hearing System

Nowadays, with the revolution of the information exchangesaccompanied with the Internet, most of the applications all rely on anetwork to launch, the related products are abundant. Connecting witheach other and connecting application expand various applied realm andthe need market, make the network product become a developmentmain current, but also it produces some worries:people depend on anetwork excessively, the credibility and affection exchanges of thesafety,information are subjected to harassment.Especially on theperson's origin, the creative thinking is suppressed,the traditional andmodern emergence become disjointed,the knowledge spread to bear tothe challenge.In consideration of these factor, the application that theinformation for make people the center spread become international upstudy of a little bit hot and trend.Mobile electonic seeing and hearing system descends a developmentaccording to the above-mentioned background, its exploitation faces tonoconnect protocol (UDP/IP) in the convenience on the application, thebroadcast that caters to a multi-media data deliver, making it be likesimilar convenience of radio broadcast. It is more rational and convenientin the information exchanges situation application of the small scopeespecially. For example:On the meeting, in the classroom, people canmake use of that system and can download the contents of speech easily,avoiding complicated record process, that is the research purpose placeof that system.The thesis mainly provided a set of concrete solution for the softwaredesign that moves the electronics audio-visual system to send out tocarry, that project collected from the data, arriving the compression of thedata, arriving again a data to deliver, to each function mold piece carry onIVdetailed with deep analysis, and put forward various possible solutions,and in the end, give the best answer keeping with it applicationenvironment of solution.The data collecting makes use of the equipments description watchinside the windows and two API functions, completing a data veryconveniently to get to applied procedure from the hardware equipments.Because the mobile electonic seeing and hearing system establishsin the wireless, under the influence of bandwidth and the networkexpense, we hope deliver of the document can be as small as possible.So we adopts to compress a ratio greatly and lose really small ofaccording to the JPEG of the DCT calculate way compress method.In the data transmission module, it is impossible for the server to passthree handshakes to carry the establishment conjunction with customer,but direct use data the data report of the way sends out to carry forcustomer without intermission, and in order not to the waste and thenetwork burden of the network bandwidth resources is over-weight, weselect by examinations according to have no much sow of conjunctioncorrespondence technique.Deliver the electronics of the structure to move the audio-visualsystem conduct and actions according to the wireless multi-media datathe new high-tech IT product contain vast market need, can fill up awireless data of small scope(80 meter) to deliver the market blank of theaudio-visual product, the industry turns the development trend explicit,the economic performance showsMobile electonic seeing and hearing system with the applicationdissimilarity of the in general use PDA handheld PC and the notebook,the data adopt delivers the agreement and way also different.The Mobileelectonic seeing and hearing system since can see is the appropriationelectronics then label, can see again is a notebook to expand an outsideto establish.Therefore, the electronics moves the audio-visual plank anonexistent market a competition a problem with the existing in generaluse computer product.In order to delivering the mobile electonic seeing and hearing systemfixed position of the structure to move environment in the meeting,theclassroom tie area according to the wireless multi-media data under ofapplication, its cost is much lower than the similar products(PDA,NB), themarket potential is huge.Because this system belongs to the information system integrationproducts, the development and industry become originally lower, but theadditional value of the product is very high, therefore, the risk of marketexpandings is lower, this system is the high function and low pricehigh-tech IT new product.The market of the mobile electonic seeing and hearing system haslatent and huge application space such as that year of thesemi-conductor radio and magnetic tape record. It has incomparable ofsociety,economic meanings.
