data bit meaning in Chinese

数据位
数据信号位

2 . when the existed dynamic bit rate allocation algorithms is working , the video data bit rate and the audio data bit rate are changed
2 )已有的动态速率调整算法在进行动态速率调整时，音、视频的位速率都要改变。
Comparing with the existed dynamic bit rate allocation algorithms , the model can provide better audio data quality by adjusting the video data bit rate . this meets the requirement in remote education system
本模块只对视频位速率进行调整，保持音频位速率不变，保证音频质量，在一定程度能满足远程教育的需要。
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
与静态图像、视频等数字水印方法类似，音频水印的研究主要须解决感知透明性、数据嵌入率、鲁棒性、安全性以及实时性等问题。水印算法的鲁棒性对于实际应用来说是至关重要的，它要求数字水印在遭受有意的攻击或无意的修改后，仍能提供有意义的数据，这一性能对版权保护的应用显得尤为突出。
