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、家庭影(ying)(ying)院：電視、投影(ying)(ying)

家庭影(ying)(ying)(ying)(ying)院系統(tong)一(yi)般使(shi)(shi)用(yong)(yong)電(dian)(dian)視(shi)或者投(tou)(tou)影(ying)(ying)(ying)(ying)作(zuo)為畫面(mian)呈現方式，如(ru)果使(shi)(shi)用(yong)(yong)電(dian)(dian)視(shi)顯(xian)示(shi)畫面(mian)，其控制(zhi)就非常簡單(dan)，所(suo)以這里就不多(duo)說了，重點說一(yi)下(xia)(xia)投(tou)(tou)影(ying)(ying)(ying)(ying)機。投(tou)(tou)影(ying)(ying)(ying)(ying)機需要配(pei)合(he)幕布使(shi)(shi)用(yong)(yong)，也有朋友會說投(tou)(tou)白(bai)墻(qiang)也行(xing)，但(dan)是實(shi)際上，投(tou)(tou)白(bai)墻(qiang)的效果是比較差的，同時，幕布還(huan)有一(yi)個好(hao)處是可(ke)(ke)以遮擋(dang)一(yi)些(xie)東西(xi)，比如(ru)說你想投(tou)(tou)影(ying)(ying)(ying)(ying)到電(dian)(dian)視(shi)所(suo)在(zai)的墻(qiang)面(mian)，全可(ke)(ke)以放(fang)(fang)下(xia)(xia)幕布遮住電(dian)(dian)視(shi)就可(ke)(ke)以了。對(dui)于投(tou)(tou)影(ying)(ying)(ying)(ying)機來說，一(yi)般可(ke)(ke)以采用(yong)(yong)桌面(mian)擺放(fang)(fang)、吊裝、支架安裝等方式，紅外(wai)線遙(yao)控控制(zhi)，且(qie)多(duo)數投(tou)(tou)影(ying)(ying)(ying)(ying)機都會在(zai)機身前后分(fen)別設置遙(yao)控接收(shou)窗，方便從前后兩個方向接收(shou)紅外(wai)線遙(yao)控信號。

2、視頻傳(chuan)輸與呈現

從視(shi)頻(pin)源到(dao)投影機(ji)可(ke)以(yi)采用(yong)(yong)VGA、AV、HDMI等方式(shi)傳(chuan)輸視(shi)頻(pin)信號(hao)(hao)，當然，前兩者屬于比(bi)較老的(de)方式(shi)，傳(chuan)輸效果比(bi)較差，信號(hao)(hao)容(rong)易(yi)衰減，現在使用(yong)(yong)的(de)越(yue)來越(yue)少，目前的(de)主流(liu)的(de)方式(shi)為(wei)HDMI。HDMI為(wei)全數字方式(shi)傳(chuan)輸音視(shi)頻(pin)信號(hao)(hao)，一條線就(jiu)可(ke)以(yi)把視(shi)頻(pin)和音頻(pin)信號(hao)(hao)同時傳(chuan)輸。

有(you)朋友可能想(xiang)到視頻的(de)(de)無(wu)線傳(chuan)(chuan)(chuan)輸(shu)，就(jiu)目前(qian)而(er)言，無(wu)線網絡的(de)(de)速(su)(su)度(du)(du)還(huan)不足以傳(chuan)(chuan)(chuan)輸(shu)信息(xi)量(liang)巨(ju)大(da)的(de)(de)高清視頻，以wifi為例，目前(qian)有(you)一些(xie)投(tou)影機支持wifi投(tou)影，但(dan)是(shi)傳(chuan)(chuan)(chuan)輸(shu)速(su)(su)度(du)(du)受wifi速(su)(su)度(du)(du)的(de)(de)影響，靜(jing)態(tai)(tai)畫面有(you)不錯的(de)(de)效果，但(dan)是(shi)對(dui)于數據量(liang)巨(ju)大(da)的(de)(de)動態(tai)(tai)畫面，一般(ban)都會發生卡頓，這(zhe)(zhe)是(shi)由這(zhe)(zhe)些(xie)技(ji)術的(de)(de)底層決(jue)定(ding)的(de)(de)，所以目前(qian)用無(wu)線來傳(chuan)(chuan)(chuan)輸(shu)視頻信號(hao)(hao)，特別是(shi)高清視頻信號(hao)(hao)還(huan)是(shi)不太(tai)現(xian)實的(de)(de)。

3、音頻傳輸與放大(da)

前(qian)面(mian)說(shuo)過(guo)，如果采用HDMI傳(chuan)輸(shu)(shu)的(de)(de)(de)話，聲音(yin)信號(hao)也是(shi)(shi)一(yi)并(bing)(bing)傳(chuan)輸(shu)(shu)的(de)(de)(de)，所(suo)以(yi)可(ke)(ke)以(yi)通過(guo)HDMI直(zhi)接(jie)傳(chuan)輸(shu)(shu)聲音(yin)信號(hao)到(dao)功(gong)放(fang)機(ji)，也可(ke)(ke)以(yi)通過(guo)HDMI音(yin)頻(pin)分離器(qi)將聲音(yin)信號(hao)分離后送入功(gong)放(fang)機(ji)。功(gong)放(fang)機(ji)接(jie)收到(dao)音(yin)頻(pin)數據后進(jin)行(xing)解碼并(bing)(bing)對(dui)功(gong)率進(jin)行(xing)放(fang)大(da)，直(zhi)接(jie)驅動音(yin)箱發出聲音(yin)。當然，除此之外，音(yin)頻(pin)信號(hao)也可(ke)(ke)以(yi)使用AV線、光纖等其他方式傳(chuan)輸(shu)(shu)，原理(li)大(da)同小(xiao)異，這里就不多說(shuo)了。對(dui)于音(yin)頻(pin)設備而言，功(gong)放(fang)機(ji)是(shi)(shi)為重要(yao)的(de)(de)(de)，功(gong)放(fang)機(ji)一(yi)般(ban)采用紅外遙控控制。

4、幕布

幕(mu)布(bu)(bu)(bu)大家應該都熟悉，但是這里要(yao)說(shuo)一下幕(mu)布(bu)(bu)(bu)的(de)控(kong)(kong)(kong)(kong)(kong)制方式以(yi)方便后(hou)面(mian)的(de)改(gai)造。幕(mu)布(bu)(bu)(bu)需要(yao)控(kong)(kong)(kong)(kong)(kong)制的(de)就是升降，有(you)(you)手動(dong)和(he)遙(yao)(yao)(yao)控(kong)(kong)(kong)(kong)(kong)兩種方式，手動(dong)控(kong)(kong)(kong)(kong)(kong)制就不(bu)多說(shuo)了。遙(yao)(yao)(yao)控(kong)(kong)(kong)(kong)(kong)一般(ban)采用紅(hong)(hong)外(wai)遙(yao)(yao)(yao)控(kong)(kong)(kong)(kong)(kong)和(he)射頻遙(yao)(yao)(yao)控(kong)(kong)(kong)(kong)(kong)，紅(hong)(hong)外(wai)遙(yao)(yao)(yao)控(kong)(kong)(kong)(kong)(kong)需要(yao)將遙(yao)(yao)(yao)控(kong)(kong)(kong)(kong)(kong)器面(mian)對(dui)幕(mu)布(bu)(bu)(bu)的(de)遙(yao)(yao)(yao)控(kong)(kong)(kong)(kong)(kong)接收器，射頻遙(yao)(yao)(yao)控(kong)(kong)(kong)(kong)(kong)沒有(you)(you)方向(xiang)性。當然，對(dui)于手動(dong)控(kong)(kong)(kong)(kong)(kong)制的(de)幕(mu)布(bu)(bu)(bu)，智能影音(yin)公司強烈建議購買(mai)相應的(de)幕(mu)布(bu)(bu)(bu)遙(yao)(yao)(yao)控(kong)(kong)(kong)(kong)(kong)組件，也分(fen)紅(hong)(hong)外(wai)遙(yao)(yao)(yao)控(kong)(kong)(kong)(kong)(kong)和(he)射頻遙(yao)(yao)(yao)控(kong)(kong)(kong)(kong)(kong)兩種，價(jia)格(ge)非常(chang)便宜(yi)，接線安裝也非常(chang)簡單，全可以(yi)自己搞定。
