電(dian)(dian)視盒(he)子是(shi)一(yi)個小型的(de)計算終端設備(bei)，只要簡(jian)單的(de)通過HDMI或(huo)色差線等技術將其與傳(chuan)統(tong)(tong)電(dian)(dian)視連接，就(jiu)能在傳(chuan)統(tong)(tong)電(dian)(dian)視上實現網頁瀏覽、網絡視頻(pin)播(bo)放、應用程序安裝，甚至能將你手機、平板(ban)中的(de)照片和視頻(pin)投射到家中的(de)大屏(ping)幕電(dian)(dian)視當中。

它(ta)可以將(jiang)互聯網(wang)內容通(tong)過其在電(dian)(dian)(dian)(dian)視(shi)(shi)機上進行(xing)播放(fang)，此(ci)前在互聯網(wang)領(ling)域被稱之(zhi)(zhi)為(wei)網(wang)絡高清(qing)播放(fang)機，后被廣電(dian)(dian)(dian)(dian)總(zong)局定義為(wei)互聯網(wang)電(dian)(dian)(dian)(dian)視(shi)(shi)機頂(ding)盒(he)(he)(he)。它(ta)與可接入互聯網(wang)的(de)智能電(dian)(dian)(dian)(dian)視(shi)(shi)一起(qi)，統稱為(wei)“互聯網(wang)電(dian)(dian)(dian)(dian)視(shi)(shi)”。業內認為(wei)，隨著(zhu)國家(jia)對(dui)于版權(quan)問題的(de)愈發重(zhong)視(shi)(shi)，電(dian)(dian)(dian)(dian)視(shi)(shi)盒(he)(he)(he)子(zi)上的(de)“免費午餐”將(jiang)會越來越少，其市場競(jing)爭力亦會隨之(zhi)(zhi)減弱。而目(mu)前大部分智能電(dian)(dian)(dian)(dian)視(shi)(shi)在功能和(he)使用上，具備甚(shen)至(zhi)已超過了(le)電(dian)(dian)(dian)(dian)視(shi)(shi)盒(he)(he)(he)子(zi)，更多廠商(shang)在新品開發過程中也愿意將(jiang)機頂(ding)盒(he)(he)(he)功能內置在電(dian)(dian)(dian)(dian)視(shi)(shi)中，因此(ci)電(dian)(dian)(dian)(dian)視(shi)(shi)盒(he)(he)(he)子(zi)今后或和(he)智能電(dian)(dian)(dian)(dian)視(shi)(shi)“合體”。
