重慶中文字幕日韓歐美一區二區三區:智能影音系統為我們帶來好的家庭視覺和聽覺享受，那么實際上，你對中文字幕日韓歐美一區二區三區:智能影音系統了解嗎，智能影音系統都有哪些基礎知識，又該如何改造呢。

1、家庭(ting)影院：電視(shi)、投影

家庭影(ying)院系統一(yi)般(ban)使用電(dian)視或者(zhe)投(tou)影(ying)作為畫面(mian)呈現方(fang)式，如(ru)果使用電(dian)視顯示畫面(mian)，其控(kong)(kong)制就非常簡單，所(suo)以這(zhe)里(li)就不(bu)多說(shuo)了，重(zhong)點(dian)說(shuo)一(yi)下投(tou)影(ying)機(ji)(ji)。投(tou)影(ying)機(ji)(ji)需要配(pei)合(he)幕(mu)布使用，也(ye)有朋友(you)會說(shuo)投(tou)白(bai)墻(qiang)也(ye)行，但是實(shi)際(ji)上，投(tou)白(bai)墻(qiang)的效果是比(bi)較差的，同時，幕(mu)布還有一(yi)個好處是可以遮(zhe)擋一(yi)些東西，比(bi)如(ru)說(shuo)你想投(tou)影(ying)到電(dian)視所(suo)在(zai)(zai)的墻(qiang)面(mian)，全(quan)可以放(fang)(fang)下幕(mu)布遮(zhe)住(zhu)電(dian)視就可以了。對于投(tou)影(ying)機(ji)(ji)來說(shuo)，一(yi)般(ban)可以采用桌(zhuo)面(mian)擺放(fang)(fang)、吊裝、支(zhi)架安裝等方(fang)式，紅外線(xian)遙控(kong)(kong)控(kong)(kong)制，且多數投(tou)影(ying)機(ji)(ji)都會在(zai)(zai)機(ji)(ji)身前(qian)后(hou)分別設置遙控(kong)(kong)接收窗，方(fang)便(bian)從(cong)前(qian)后(hou)兩個方(fang)向接收紅外線(xian)遙控(kong)(kong)信號(hao)。

2、視頻傳輸與呈現

從(cong)視(shi)頻(pin)源到投影機可以采用VGA、AV、HDMI等方式(shi)傳輸視(shi)頻(pin)信(xin)號，當然，前(qian)兩者(zhe)屬于比較老的(de)方式(shi)，傳輸效果比較差(cha)，信(xin)號容易(yi)衰減(jian)，現(xian)在使用的(de)越來越少，目(mu)前(qian)的(de)主流的(de)方式(shi)為(wei)HDMI。HDMI為(wei)全(quan)數(shu)字方式(shi)傳輸音(yin)視(shi)頻(pin)信(xin)號，一(yi)條線(xian)就可以把(ba)視(shi)頻(pin)和音(yin)頻(pin)信(xin)號同時傳輸。

有朋(peng)友可能想到視頻的(de)(de)無(wu)線(xian)傳(chuan)輸，就目前而(er)言，無(wu)線(xian)網絡的(de)(de)速度(du)(du)還不(bu)足(zu)以(yi)傳(chuan)輸信(xin)息(xi)量巨(ju)大的(de)(de)高(gao)清視頻，以(yi)wifi為例，目前有一些投影機支(zhi)持wifi投影，但(dan)是(shi)(shi)傳(chuan)輸速度(du)(du)受wifi速度(du)(du)的(de)(de)影響，靜態畫面有不(bu)錯的(de)(de)效果，但(dan)是(shi)(shi)對于數(shu)據量巨(ju)大的(de)(de)動態畫面，一般都會發(fa)生(sheng)卡頓(dun)，這是(shi)(shi)由這些技術的(de)(de)底層(ceng)決定的(de)(de)，所以(yi)目前用(yong)無(wu)線(xian)來傳(chuan)輸視頻信(xin)號，特別(bie)是(shi)(shi)高(gao)清視頻信(xin)號還是(shi)(shi)不(bu)太現實的(de)(de)。

3、音頻(pin)傳(chuan)輸與放大(da)

前面說過(guo)，如(ru)果采用HDMI傳(chuan)輸的話(hua)，聲(sheng)(sheng)音(yin)信(xin)號(hao)(hao)也(ye)是(shi)一并傳(chuan)輸的，所以可以通(tong)過(guo)HDMI直(zhi)接(jie)傳(chuan)輸聲(sheng)(sheng)音(yin)信(xin)號(hao)(hao)到(dao)功(gong)放機，也(ye)可以通(tong)過(guo)HDMI音(yin)頻分(fen)離(li)器將聲(sheng)(sheng)音(yin)信(xin)號(hao)(hao)分(fen)離(li)后送入功(gong)放機。功(gong)放機接(jie)收(shou)到(dao)音(yin)頻數據后進(jin)行解碼并對(dui)功(gong)率進(jin)行放大，直(zhi)接(jie)驅動(dong)音(yin)箱發出(chu)聲(sheng)(sheng)音(yin)。當然(ran)，除此之外(wai)(wai)，音(yin)頻信(xin)號(hao)(hao)也(ye)可以使用AV線、光纖(xian)等其他方(fang)式傳(chuan)輸，原(yuan)理大同小異，這(zhe)里就(jiu)不多說了。對(dui)于音(yin)頻設(she)備而(er)言，功(gong)放機是(shi)為(wei)重要的，功(gong)放機一般采用紅外(wai)(wai)遙控控制。

4、幕布

幕(mu)(mu)(mu)布大(da)家(jia)應(ying)該都熟悉，但是(shi)這里(li)要說(shuo)一下幕(mu)(mu)(mu)布的控(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)方式以方便后面的改造。幕(mu)(mu)(mu)布需要控(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)的就是(shi)升降(jiang)，有手(shou)動(dong)和遙(yao)控(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)兩種方式，手(shou)動(dong)控(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)就不多說(shuo)了(le)。遙(yao)控(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)一般采用紅外遙(yao)控(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)和射(she)頻遙(yao)控(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)，紅外遙(yao)控(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)需要將遙(yao)控(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)器面對(dui)幕(mu)(mu)(mu)布的遙(yao)控(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)接(jie)收器，射(she)頻遙(yao)控(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)沒(mei)有方向(xiang)性。當然，對(dui)于手(shou)動(dong)控(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)的幕(mu)(mu)(mu)布，智能影音(yin)公司強烈建議購買相(xiang)應(ying)的幕(mu)(mu)(mu)布遙(yao)控(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)組件，也分(fen)紅外遙(yao)控(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)和射(she)頻遙(yao)控(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)兩種，價(jia)格非常便宜，接(jie)線安裝也非常簡單，全可以自己搞(gao)定。
