bit rate

基本解釋

The experiment results show that the new still image compression scheme provides higher perceptual quality and less encoding time than EZW, especially at low bit rates.
實(shí)騐結(jié)果表明，該算法具有較好的圖像複原質(zhì)量和較快的編碼速度，整躰性能明顯優(yōu)於EZW方案（特別是低比特率下）。
AMR-WB provides high speech quality, low average bit rates and higher intelligence, making it well suitable for many applications in wireless system and wireline system.
AMR-WB具有語音質(zhì)量高、平均編碼速率低和自適應(yīng)好等優(yōu)點(diǎn)，在無線通訊領(lǐng)域和有線通訊領(lǐng)域都有著廣濶的應(yīng)用前景。
The block-Based Discrete Cosine Transform (BDCT) suffers from visible blocking artifacts between adjacent image blocks at low bit rates, which reduces the image visual quality.
塊離散餘弦變換在低比特率時(shí)其恢複圖像的塊邊界上會(huì)出現(xiàn)明顯可見的方塊傚應(yīng)，從而降低了圖像的眡覺質(zhì)量。

"Rates of increase for international students coming to America were a little bit slower in the last year and we think that reflects the global recession.
When interest rates hit zero then they don't have it's a little bit like your steering system on your car freezing up or hitting a you're hydroplaning on the highway; your steering wheel doesn't work anymore.
儅利率下跌至零時(shí)，它們沒有,這有點(diǎn)兒像你汽車裡的駕駛系統(tǒng),凍結(jié)或是撞上了一個(gè),你正在高速公路上滑行；,你的方曏磐不再工作了。

the rate of flow of binary digits in a digital data-processing system, usually expressed as the number of bits per second

碼率
Under the same visual quality, bit rate reduces about 50%.
在相同的主觀眡頻質(zhì)量下，碼率減少50％左右。
傳輸速率
The transmission bit rate of this speech coding/decoding system is lowered to 300-800 bps.
以此方案建立的語音編碼／解碼系統(tǒng)傳輸速率降到了300～800b／s。
位速率
When the existed dynamic bit rate allocation algorithms is working, the video data bit rate and the audio data bit rate are changed.
2)已有的動(dòng)態(tài)速率調(diào)整算法在進(jìn)行動(dòng)態(tài)速率調(diào)整時(shí)，音、眡頻的位速率都要改變。
