傑出研究計劃 Outstanding Research Project 工程學院 Faculty of Engineering 無線互聯網視像研究 Video over Internet and Wireless (VIEW) Technologies 工程學院三個學系（包括計算機科學與工程學系、訊息工程學系和系統工 程與工程管理學系）合作設立無線互聯網視像 ( VIEW) 研究實驗室，以 開發在互聯網及移動網絡上存取視像的先進技術和應用。 其中的重要研究領域是視頻信息處理。視頻信息處理是解決視頻在移 動網絡傳送應用的技術，能夠在視頻中抽取各種模式的信息，並篩選 重要的內容傳送予移動網絡用戶。實驗室與本地電視台合作，將視頻 信息處理技術應用於製作日常互聯網電視節目。 另一個重要研究領域是開發無線及移動環境的應用技術，目標是令 媒體資料只須經編輯一次，就可以應用在不同的無線及移動平 台。 實驗室獲創新及科技基金資助，並利用最新的技術，開發在互 L 聯網及無線環境中多語言視像內容的管理及傳送技術，以配合 I 香港的市場趨勢。二零零一年初，實驗室使用移動電話網絡在 f 香港進行首次視像傳送；同年夏天，針對個人數碼助理的數 字視像圖書館系統 「i-VIEW」 ，更於移動電話網絡及藍芽網 絡上進行測試。 實驗室將於二零零三年初，聯同香港流動通訊及亞洲電 視，利用其開發的「視頻轉換多媒體短訊技術」 (Video2MMS) ，提供經手提電話收看電視的服務。 The three departments of Computer Science and Engineering, Information Engineering , and Systems Engineering and Engineering Management jointly established a laboratory focusing on new technologies and applications to support the delivery of video over the Internet with mobile access capabilities. One major area of research is video information processing, a technique to cope with video delivery over the mobile environment. Information from different channels in the video is extracted and only relevant and important parts are transmitted to mobile users. Through collaboration with a local television company, the video information processing techniques are being applied to the daily workflow of television programme production for the Internet. Another research focus is the development of applications in wireless and mobile environments. The target is to author the media data so that it can be used on different wireless and mobile platforms. Efforts at developing techniques for multilingual video content management and delivery on the Internet and in wireless environments are supported by the Innovation and Technology Fund. Researchers employ state-of-the- art technologies, taking full consideration of marketing trends in Hong Kong. In early 2001, the first video transmission trail across the public GSM network in Hong Kong was conducted. In the summer of the same year, i- VIEW, the digital video library system targeted for PDA wireless access, was tested over the public GSM mobile network and the bluetooth network. Based on the Video2MMS developed by CUHK researchers, the laboratory will join Hong Kong CSL and ATV to provide television watching service on handsets in early 2003.
