電(dian)視(shi)(shi)盒子是一個小型的計算終端(duan)設備，只要(yao)簡單的通過HDMI或(huo)色差(cha)線等技術(shu)將其與傳統電(dian)視(shi)(shi)連(lian)接，就能在(zai)傳統電(dian)視(shi)(shi)上實現網頁瀏覽、網絡視(shi)(shi)頻播放、應用程(cheng)序(xu)安裝，甚至能將你手機、平板中(zhong)的照片和視(shi)(shi)頻投射到家中(zhong)的大屏幕電(dian)視(shi)(shi)當中(zhong)。

它(ta)可以將互(hu)聯(lian)網(wang)內(nei)容(rong)通過其(qi)在(zai)電(dian)(dian)(dian)視(shi)(shi)機上進行(xing)播(bo)放，此前在(zai)互(hu)聯(lian)網(wang)領域被稱之(zhi)為(wei)網(wang)絡高清播(bo)放機，后被廣(guang)電(dian)(dian)(dian)總(zong)局定義為(wei)互(hu)聯(lian)網(wang)電(dian)(dian)(dian)視(shi)(shi)機頂盒。它(ta)與可接入互(hu)聯(lian)網(wang)的(de)智能電(dian)(dian)(dian)視(shi)(shi)一起，統稱為(wei)“互(hu)聯(lian)網(wang)電(dian)(dian)(dian)視(shi)(shi)”。業內(nei)認為(wei)，隨(sui)著國家對于版權問題的(de)愈發重視(shi)(shi)，電(dian)(dian)(dian)視(shi)(shi)盒子(zi)(zi)上的(de)“免費午餐”將會(hui)越來越少，其(qi)市(shi)場競爭力亦會(hui)隨(sui)之(zhi)減弱(ruo)。而目前大部分智能電(dian)(dian)(dian)視(shi)(shi)在(zai)功能和使用(yong)上，具備甚至已超過了電(dian)(dian)(dian)視(shi)(shi)盒子(zi)(zi)，更多廠商在(zai)新品開發過程中(zhong)也愿意將機頂盒功能內(nei)置在(zai)電(dian)(dian)(dian)視(shi)(shi)中(zhong)，因(yin)此電(dian)(dian)(dian)視(shi)(shi)盒子(zi)(zi)今后或和智能電(dian)(dian)(dian)視(shi)(shi)“合體”。
