電(dian)(dian)視盒子是(shi)一個小型的計算終端(duan)設備(bei)，只要(yao)簡單的通過HDMI或色差線(xian)等技(ji)術將(jiang)其與傳統(tong)電(dian)(dian)視連接，就能在(zai)傳統(tong)電(dian)(dian)視上實(shi)現網頁瀏覽、網絡視頻(pin)播放、應用程序安裝，甚至能將(jiang)你手機、平板中(zhong)的照片和(he)視頻(pin)投(tou)射到家中(zhong)的大屏(ping)幕電(dian)(dian)視當中(zhong)。

它(ta)可以將(jiang)互聯(lian)網內(nei)容(rong)通過(guo)其在(zai)(zai)電(dian)(dian)視機上(shang)進行播放(fang)，此前(qian)在(zai)(zai)互聯(lian)網領域被稱(cheng)之(zhi)為(wei)(wei)網絡高清播放(fang)機，后被廣電(dian)(dian)總局定義為(wei)(wei)互聯(lian)網電(dian)(dian)視機頂盒(he)。它(ta)與可接入互聯(lian)網的智(zhi)能(neng)電(dian)(dian)視一起，統(tong)稱(cheng)為(wei)(wei)“互聯(lian)網電(dian)(dian)視”。業(ye)內(nei)認為(wei)(wei)，隨著(zhu)國家對(dui)于(yu)版權問題的愈(yu)發(fa)重視，電(dian)(dian)視盒(he)子上(shang)的“免費午餐”將(jiang)會越來(lai)越少，其市(shi)場競爭力亦會隨之(zhi)減弱(ruo)。而目前(qian)大部分智(zhi)能(neng)電(dian)(dian)視在(zai)(zai)功能(neng)和使(shi)用上(shang)，具備甚至已超過(guo)了電(dian)(dian)視盒(he)子，更多(duo)廠商在(zai)(zai)新(xin)品開發(fa)過(guo)程中也愿意將(jiang)機頂盒(he)功能(neng)內(nei)置(zhi)在(zai)(zai)電(dian)(dian)視中，因此電(dian)(dian)視盒(he)子今后或和智(zhi)能(neng)電(dian)(dian)視“合體(ti)”。
