digital bit rate 中文意思是什麼
digital bit rate
解釋
數字位率-
Resemble with the digital watermark methods of the other media such as still image and video, digital audio watermark must account for some problems which consist of perceptual transparency, data bit rate, robustness, security and real - time etc. the robustness of watermark is vital to the practical application, which requires the watermark providing with significant data since it suffered from some intended attacks or unintended revisal
與靜態圖像、視頻等數字水印方法類似，音頻水印的研究主要須解決感知透明性、數據嵌入率、魯棒性、安全性以及實時性等問題。水印演算法的魯棒性對于實際應用來說是至關重要的，它要求數字水印在遭受有意的攻擊或無意的修改後，仍能提供有意義的數據，這一性能對版權保護的應用顯得尤為突出。 -
In the past few years, there has been significant interest in digital video applications like video conferencing and video e - mailing over internet, video telephony over public switched telephone networks ( pstn ) and wireless networks, etc. by removing spatio - temporal redundancies existing in adjacent frames, motion estimation can reduce the coding bit - rate significantly
低速率視頻編碼技術已在許多領域得到了應用，如在pstn （公共電話網） 、無線網、 n - isdn （窄帶綜合業務數字網） 、 b - isdn （寬帶綜合業務數字網）上傳輸視頻會議、可視電話和無線手持終端等。 -
