縮圖

縮圖是圖片的縮小版本,可用於輕鬆識別 圖片。 縮圖對圖像的作用,與標準文字索 引對單字的作用一樣。

S

S/PDIF (SPDIF)Sony/Philips 數碼界面)

Sony Philips 聯合開發的一種標準音訊 檔案傳輸格式。 S/PDIF 允許在不同的裝置 間傳輸數碼音訊訊號,而不用首先轉換為 類比訊號。 這可避免在傳輸為類比訊號期 間出現音訊訊號質量降級的現象。

壓縮

在音訊術語中,這是一種臨時或永久性縮 減音訊資料以提升儲存或傳輸效率的處理 程序。 臨時縮小檔案大小的方式稱為「無 損耗」壓縮,這種壓縮方式不會丟失任何 資訊。 永久性縮小檔案大小的方式(如縮

MP3 檔案)稱為「損耗」壓縮,這種壓 縮方式將丟棄非必要的資訊,因而難免會 失去部分資訊。

隨機

一種隨機播放音訊檔案(曲目)的功能。

V

VBR(變動位元速率)

透過VBR,編碼器可盡可能多地獲取所需 的位元。 因此,黑色圖片獲得較少的位 元,而複雜圖片則盡可能多地獲得它們所 需的位元。 儘管這樣可提供最佳品質,但 完全無法預測最終大小。

S

SPL(聲壓級)

聲能的聲音測量。 1 dB SPL 是聲音級中一 般人能夠感覺到的最小增量。 理論上,0 dB SPL 是人類聽覺的閾值,而約 120 dB 則 是不適聽力的閾值。

W

W(瓦)

功率的衡量單位。 在揚聲器中,瓦是一個 特定的術語,用以指明處理放大器電壓輸 入的功率處理特性。

串流

傳輸數據的一種技術,以便數據可處理為 一種穩定和持續流。 串流技術通常用於互 聯網,因為很多用戶沒有足夠快的存取權 限來快速下載大型多媒體檔案,這樣,客 戶端瀏覽器或插件可在整個檔案傳輸完之 前即開始顯示數據。

專輯封面

專輯封面是 NP2900 的功能之一,可顯示 音樂專輯的藝術佳作(封面圖片)。 此類 顯示可讓用戶快速辨認音樂專輯。 音樂專 輯的藝術佳作檔案可從互聯網下載。

P

PCM(脉衝編碼調製)

數碼錄製的初創形式。

U

UPnP(隨插即用)

隨插即用是一種網絡架構,由眾多公司聯 盟共同開發,用於確保來自不同供應商產 品之間的輕鬆連線。 UPnP 裝置應能夠自 動連接到網絡,以便在閒暇時能夠處理標 識和其他流程。 UPnP Forum 開發的標準 為:與媒體、平台和裝置無關。

靜音

接收器上的一個控件、使訊號路徑或輸出 靜音的一些混頻器或訊號處理單元。

音量

音量是最常見的詞彙,用以控制聲音相對 響度的大小。 它也與很多電子裝置上用於 控制響度大小的功能相關。

歐姆

電流阻力(阻抗)單位。 揚聲器的阻抗越 低,則表示越難驅動。
