• SDI(Serial digital interface) : 由SMPTE(Society of Motion Picture and Television Engineers)所制定, 在coaxial cable上數位影像傳輸協定
• Digital video interface : is a video interface standard designed to maximize the visual quality of digital display devices such as flat panel LCD computer displays and digital projectors. It was developed by an industry consortium, the Digital Display Working Group (DDWG). It is designed for carrying uncompressed digital video data to a display. It is partially compatible with the High-Definition Multimedia Interface (HDMI) standard in digital mode (DVI-D).
• HD-SDI (High Definition Serial Digital Interface ) :
• Cable: Standard 75-ohm Coaxial cable (Same as cable TV) :
• UPnP(Universal Plug and Play ) : 是由通用型即插即用論壇（UPnP™ Forum）提出的一套網路協定。該協定的標的是使家庭網路（資料共享、通信和娛樂）和公司網路中的各種裝置能夠相互無縫連線,並簡化相關網路的實現。UPnP 透過定義和發布基於開放、網際網路通訊網協定標準的 UPnP 裝置控制協定來實現這一標的。

2. Media Player Interoperability Standards

目的 :

• 定義存取設備的功能介面
• 統一介面使不同功能的播放器都能執行
• 降低依賴某特定播放器產品的機會

現有標準 :

• W3C SMIL
  http://www.ws.org.tw/sws/index.php?option=com_content&task=view&id=22&Itemid=48
  
• DLNA :「Digital Living Network Alliance」聯盟的簡稱，此聯盟的任務是制定一個統一的傳輸規範，讓各種不同廠牌、類型的影音機材能相互溝通。因此，只要是符合DLNA的影音機材，就能在不需驅動程式、轉接裝置下直接連結、同步動作，甚至是傳輸資料。
• NMPR(Networked Media Product Requirements)是Intel所制定的一套內容詳盡的規範，在通訊協定層面達到網路媒體的互通性。設計符合NMPR規範的產品，不僅讓產品功能可符合現有的產業標準，並讓業者能自由加入更高階的功能。

3. Screen Media Formats

目的 :

• 使得在網路另一端的播放內容能有相容的格式
• 減少內容產品與其開發工具的成本

現有標準 :

Interactivity standard

• VoiceXML 2.0 : 主要用在使用語音命令代替按鍵輸入的過程中，可以自動對商務電話進行回覆。不但能夠提高通話品質還能名進行訊息搜集和恢復等。這一標準可以在網上使用，也可離線使用。目前，惠普、摩托羅拉、ScanSoft和Tellme Networks等公司都對VoiceXML 2.0標準進行過審議，鑒於這一標準的複雜性，W3C對其進行的評估超過了以往任何標準。
• SRGS : 是對VoiceXML的補充，用於語音識別，還可以將終端用戶的回應轉換成話音提示。

Screen format

• Aspect ration (長寬比) : 4:3 , 3:2 , 16:9 , 1.85:1 , 2.39:1
• Contrast Ratio (亮度比) : 300:1 , 400:1 ...

Multimedia format

• ASF format (Advanced Streaming Format) is specially designed to run over the Internet.
  ASF files can contain audio, video, slide shows, and synchronized events.
  ASF files can be highly compressed and can be delivered as a continuous flow of data (on-line TV or radio). Files can be of any size, and can be compressed to match many different bandwidths (connection speeds).
• ASX (Advanced Stream Redirector) files are not media files, but metafiles.
  Metafiles provides information about files. ASX files are plain text files used to describe multimedia content. The file above describes three multimedia files. When the ASX file is read by a player, the player can play the files described.
• WMA (Windows Media Audio) format is an audio format developed by Microsoft.
  WMA is designed to handle all types of audio content. The files can be highly compressed and can be delivered as a continuous flow of data (on-line radio). WMA files can be of any size, and be compressed to match many different bandwidths (connection speeds).
  The WMA format is similar to the ASF format.
• WMV (Windows Media Video) format is a video format developed by Microsoft.
  WMV is designed to handle all types of video content. The files can be highly compressed and can be delivered as a continuous flow of data (on-line radio). WMV files can be of any size, and be compressed to match many different bandwidths (connection speeds).
  The WMV format is similar to the ASF format.
• WAX (Windows Media Audio Redirector) files are much the same as ASX files, but intended to describe audio files (.wma files)
• WMP (Windows Media Player) files and WMX are reserved file types for future use by Windows.

動態格式標準 :

• 2D文字（SMIL、SVG）
• 附有動畫文字的全互動3D佈景（FBA、BIFS）
• MPEG-4 : Face and Body Animation（FBA）標準尤其為人臉辨識（face and humanoid skeleton）提供一套動畫格式，以及為任何定位(position)、orientation values的時間序列編碼提供免費動畫格式。談話的面孔傳輸速率約為每秒2千位元，身體所需的傳輸速率則為每秒5至20千位元。單純佈景的動畫包括一個講話的人物以及身體與背景，能夠在每秒數個千位元之內完成傳送。這個範例是以每秒15格畫面在行動電話播放。
