audio component 中文意思是什麼
audio component
解釋
聲頻成分-
Support for transcoding all supported audio formats using the converter component ( requires external commandline encoder executables for different output formats )
使用內建的轉換組件可以轉換所以支持的音頻格式（不同的輸出格式需要外部命令行編碼器可執行程序） -
The project uses for reference the algorithm thought of sbc ( subband coding ) to measure off the audio to the corresponding frequency width and encode it by the different sensitivity of human hearing, which results in the lower coding rate and bearable voice quality. the algorithm processing low bit - rate audio is designed to be self - adaptive by the situation of network. the component developped by that algorithm and project has already been used in the realtime interactive educational system
該方案借鑒sbc （ subbandcoding ）子帶編碼演算法思想，將音頻按對人聽覺敏感程度不同劃分為相應的頻帶並進行相應的編碼，從而得到較低的編碼率和較好的語音質量，設計了可根據網路狀況進行自適應的低帶寬音頻處理演算法。 -

In the part 2 of advanced audio video coding standard avs - p2, many efficient coding tools are adopted in motion compensation, such as new motion vector prediction, symmetric matching, quarter precision interpolation, etc. however, these new features enormously increase the computational complexity and the memory bandwidth requirement, which make motion compensation a difficult component in the implementation of the avs hdtv decoder
在avs - p2中傳統的運動補償技術被進一步改進以獲得更好的編碼性能。這些新的特性包括：預測塊大小可變化1616到88基於矢量三角形的新型mv預測多參考幀最多2幀或4場直接或對稱模式匹配不限制的mv和1 4精度像素插值等。 -
It is a pop method to embed watermark in frequency field, in most literature, they embed watermark into the coefficients of fft, dct, or high - frequency of dwt using quantization method, we think that : embedding watermark into the low - frequency of audio signal dwt field can improve the robustness of watermark. the watermark is embedded in the maximum of subsection of approximate component the watermark signal using quantization method, for the same quantization size, the “ noise ” added to the signal is
在頻率域嵌入水印信息，是目前一種主流的嵌入演算法，在很多文獻中，都是通過量化音頻信號的ftf系數， dct系數，或者是dwt域的高頻系數。我們認為:在小波域內的近似分量（低頻系數）中嵌入水印能夠提高數字水印的魯棒性，通過量化嵌入水印的方法，將水印嵌入到近似分量中每個分段中最大值上，因為這樣對于同一個量化步長，量化對象的幅值越大，所疊加的「噪聲」就越小，從而提高了數字水印的不可感知性。 -
