HDMI( High Definition Multimedia Interface ),即高清晰度多媒體介面,被設計來取代類比影音傳送等端子的(如: SCART 、RCA ),是種數位化影像聲音傳送介面,可以傳送無壓縮的音頻及視頻信號。HDMI提供所有相容裝置 如: DVD、 個人電腦、 機上盒、 遊戲機、 擴大機、 數位音響及電視機的一個共通的資料連接管道。 HDMI 可以同時傳送音頻和影音信號,由於音頻和視頻信號採用同一條電纜,大大簡化的安裝系統的問題。

HDMI支援各類電視及電腦格式,包括 SDTV 、 HDTV 視頻畫面,再加上多聲道數位音頻。在傳送時,各種視頻資料將被 HDMI 收發晶片以「 Transition Minimized Differential Signaling 」技術編碼成資料封包。規格初制訂時其最大畫素傳輸率為165Mpx/sec,足以支援1080p畫質每秒60張畫面,或者 UXGA 解像度(1600x1200);後來在 HDMI 1.3 規格中擴增為340Mpx/sec,以符合需求。

標準的Type A HDMI接頭有19個腳位,另有一種支援更高解像度的Type B 接頭被定義出來,但目前仍無任何廠商使用 Type B 接頭。 Type B 接頭有29個腳位,容許其傳送擴張的視頻通道以應付未來的高畫素需求,如WQSXGA(3200x2048)。

Type A HDMI 可向下相容於現今多數顯示器與顯示卡所使用的 Single-link DVI-I 或 DVI-D 介面(但不支援 DVI-A ),表示採用 DVI-D介面的訊號來源可以透過轉換線驅動 HDMI 螢幕,但是此種轉換方案並不支援音頻傳送與遙控。另如無認證的DVI螢幕也將不能收看從 HDMI 所輸出帶有 HDCP 保護加密的視頻資料。(所有 HDMI 螢幕皆支援 HDCP ,但大多數 DVI 介面的顯示器不支援 HDCP 。) Type B HDMI 接頭也將向下相容於 Dual-link DVI 介面
