While handheld devices that can access the internet over wireless networks may challenge the pc ' s pre - eminence in basic web browsing, there ' s a strong demand for powerful pcs to polish the work of other devices - everything from digital music players to video and still cameras
雖然通過無線上網的手持式數字裝置會使個人電腦原先可以上網瀏覽的優勢受到挑戰，然而人們渴望擁有強大的個人電腦，能夠使其它設備的工作更為完美，包括數字音樂播放機、攝像機和普通照相機。 -
However, most of the current wireless networks still work in low bandwidths, and mobile devices still suffer from weak computational power, short battery lifetime and limited display capability. therefore, this thesis deals with developing a very low bit - rate bi - level video coding technique, which can be used in video communications almost anywhere, anytime on any device as follows : ( 1 ) convert true color video sequences from ccd and video card to grayscale ones, ( 2 ) detect static region of successive frames by the sum of absolute differences ( sad ) and update current frame using static region of previous frame, to decrease flicker. ( 3 ) threshold the images to bi - level video sequences using ridler ' s iterative selection
為此，本論文在傳統h . 26x和mpeg - x等視頻編解碼技術的基礎上提出了一種新的基於輪廓的視頻編解碼方案，步驟如下： （ 1 ）先把從ccd攝像頭捕捉到的視頻幀序列轉換成灰度幀序列， （ 2 ）在灰度幀序列的基礎上通過sad演算法找出相鄰幀的靜態區域，用前一幀的靜態區域更新當前幀的相應區域，這樣可以降低畫面閃爍， （ 3 ）然後用灰度直方圖迭代所產生的閾值二值化圖像，生成基於輪廓的視頻幀序列， （ 4 ）最後運用基於上下文的算術編碼技術對由第三步生成的二值化視頻幀序列進行算術編碼。 -
Digital - video encode - decode chip, one of the basic components of digital - video devices, is still relying on import products
數字視頻解碼晶元是數字電視等視聽設備的核心器件，目前絕大多數仍依賴國外進口。 -
With higher bandwidth, longer distances, and a higher - powered bus, this interface is suitable for hard drives, digital video, professional audio, high - end digital still cameras, and home entertainment devices
只要有較高的帶寬較長的距離和供電能力較強的總線，這種介面就適用於硬盤數字視頻專業音頻高檔數碼相機及家庭娛樂設備。
