重慶國產精品免費一區二區三區四區: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,你對國產精品免費一區二區三區四區: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、家庭影院:電視(shi)、投影
家庭影(ying)(ying)(ying)院系統一(yi)(yi)般使(shi)用(yong)電(dian)(dian)(dian)視或者投(tou)影(ying)(ying)(ying)作為畫面呈(cheng)現方式(shi),如果使(shi)用(yong)電(dian)(dian)(dian)視顯示畫面,其控(kong)制就(jiu)非常(chang)簡單,所(suo)以(yi)這里就(jiu)不多說(shuo)了,重點(dian)說(shuo)一(yi)(yi)下(xia)投(tou)影(ying)(ying)(ying)機(ji)。投(tou)影(ying)(ying)(ying)機(ji)需要配合幕布使(shi)用(yong),也有(you)(you)朋友會(hui)說(shuo)投(tou)白墻也行,但是實際上,投(tou)白墻的(de)效果是比較差的(de),同時,幕布還有(you)(you)一(yi)(yi)個好處是可(ke)以(yi)遮擋一(yi)(yi)些東西,比如說(shuo)你想投(tou)影(ying)(ying)(ying)到電(dian)(dian)(dian)視所(suo)在的(de)墻面,全可(ke)以(yi)放下(xia)幕布遮住(zhu)電(dian)(dian)(dian)視就(jiu)可(ke)以(yi)了。對于(yu)投(tou)影(ying)(ying)(ying)機(ji)來說(shuo),一(yi)(yi)般可(ke)以(yi)采用(yong)桌面擺放、吊裝(zhuang)、支架安(an)裝(zhuang)等方式(shi),紅外(wai)線遙控(kong)控(kong)制,且多數投(tou)影(ying)(ying)(ying)機(ji)都(dou)會(hui)在機(ji)身前(qian)后分別設置遙控(kong)接收(shou)窗,方便從前(qian)后兩個方向(xiang)接收(shou)紅外(wai)線遙控(kong)信號。
2、視頻傳(chuan)輸與呈現(xian)
從視頻(pin)(pin)源(yuan)到投影(ying)機可(ke)以采用VGA、AV、HDMI等方(fang)(fang)式(shi)(shi)(shi)傳(chuan)輸(shu)視頻(pin)(pin)信號,當然,前兩者屬于(yu)比(bi)較老(lao)的方(fang)(fang)式(shi)(shi)(shi),傳(chuan)輸(shu)效果比(bi)較差,信號容易衰減(jian),現在(zai)使用的越(yue)來越(yue)少,目(mu)前的主流的方(fang)(fang)式(shi)(shi)(shi)為HDMI。HDMI為全數字(zi)方(fang)(fang)式(shi)(shi)(shi)傳(chuan)輸(shu)音視頻(pin)(pin)信號,一(yi)條線就可(ke)以把視頻(pin)(pin)和音頻(pin)(pin)信號同時傳(chuan)輸(shu)。
有(you)(you)朋友可能想到視(shi)(shi)頻的(de)(de)(de)無線傳輸,就目前而言,無線網絡的(de)(de)(de)速(su)度(du)(du)(du)還(huan)(huan)不足以(yi)傳輸信息量(liang)巨大(da)(da)的(de)(de)(de)高(gao)清視(shi)(shi)頻,以(yi)wifi為(wei)例(li),目前有(you)(you)一些投影機支持wifi投影,但是(shi)(shi)傳輸速(su)度(du)(du)(du)受wifi速(su)度(du)(du)(du)的(de)(de)(de)影響,靜態畫面有(you)(you)不錯(cuo)的(de)(de)(de)效果,但是(shi)(shi)對(dui)于數據量(liang)巨大(da)(da)的(de)(de)(de)動態畫面,一般都會發生卡(ka)頓,這是(shi)(shi)由這些技術的(de)(de)(de)底層決定(ding)的(de)(de)(de),所以(yi)目前用無線來傳輸視(shi)(shi)頻信號(hao),特別是(shi)(shi)高(gao)清視(shi)(shi)頻信號(hao)還(huan)(huan)是(shi)(shi)不太(tai)現實的(de)(de)(de)。
3、音頻傳(chuan)輸與放(fang)大
前(qian)面說過,如果采用HDMI傳輸(shu)的話,聲(sheng)音(yin)(yin)信(xin)號(hao)也(ye)是(shi)一(yi)并傳輸(shu)的,所以可以通過HDMI直(zhi)接傳輸(shu)聲(sheng)音(yin)(yin)信(xin)號(hao)到功(gong)放(fang)(fang)機(ji)(ji),也(ye)可以通過HDMI音(yin)(yin)頻(pin)(pin)分離器將聲(sheng)音(yin)(yin)信(xin)號(hao)分離后(hou)送(song)入功(gong)放(fang)(fang)機(ji)(ji)。功(gong)放(fang)(fang)機(ji)(ji)接收到音(yin)(yin)頻(pin)(pin)數據后(hou)進(jin)行解碼并對功(gong)率進(jin)行放(fang)(fang)大,直(zhi)接驅動音(yin)(yin)箱(xiang)發出(chu)聲(sheng)音(yin)(yin)。當然,除此之外,音(yin)(yin)頻(pin)(pin)信(xin)號(hao)也(ye)可以使用AV線、光纖(xian)等(deng)其他(ta)方(fang)式傳輸(shu),原理大同小(xiao)異,這里就不多說了(le)。對于音(yin)(yin)頻(pin)(pin)設備而言,功(gong)放(fang)(fang)機(ji)(ji)是(shi)為(wei)重要的,功(gong)放(fang)(fang)機(ji)(ji)一(yi)般(ban)采用紅外遙控控制。
4、幕(mu)布(bu)
幕(mu)布(bu)(bu)大家應該都熟悉,但是(shi)這里要(yao)說(shuo)一下幕(mu)布(bu)(bu)的(de)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)方(fang)式以方(fang)便(bian)后面的(de)改造(zao)。幕(mu)布(bu)(bu)需(xu)要(yao)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)的(de)就是(shi)升降(jiang),有手動和(he)(he)遙(yao)(yao)(yao)(yao)控(kong)(kong)(kong)(kong)(kong)兩(liang)(liang)種方(fang)式,手動控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)就不多說(shuo)了。遙(yao)(yao)(yao)(yao)控(kong)(kong)(kong)(kong)(kong)一般(ban)采用紅外遙(yao)(yao)(yao)(yao)控(kong)(kong)(kong)(kong)(kong)和(he)(he)射(she)頻(pin)(pin)遙(yao)(yao)(yao)(yao)控(kong)(kong)(kong)(kong)(kong),紅外遙(yao)(yao)(yao)(yao)控(kong)(kong)(kong)(kong)(kong)需(xu)要(yao)將(jiang)遙(yao)(yao)(yao)(yao)控(kong)(kong)(kong)(kong)(kong)器面對幕(mu)布(bu)(bu)的(de)遙(yao)(yao)(yao)(yao)控(kong)(kong)(kong)(kong)(kong)接收器,射(she)頻(pin)(pin)遙(yao)(yao)(yao)(yao)控(kong)(kong)(kong)(kong)(kong)沒有方(fang)向性。當然,對于手動控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)的(de)幕(mu)布(bu)(bu),智能影音公(gong)司強(qiang)烈建議購買相(xiang)應的(de)幕(mu)布(bu)(bu)遙(yao)(yao)(yao)(yao)控(kong)(kong)(kong)(kong)(kong)組件,也(ye)分紅外遙(yao)(yao)(yao)(yao)控(kong)(kong)(kong)(kong)(kong)和(he)(he)射(she)頻(pin)(pin)遙(yao)(yao)(yao)(yao)控(kong)(kong)(kong)(kong)(kong)兩(liang)(liang)種,價格非(fei)常便(bian)宜,接線安裝也(ye)非(fei)常簡(jian)單,全可以自己搞(gao)定。
