比特率 Bit rate(重定向自Data transfer rates)
在电信和电脑运算领域,比特率(中国大陆作比特率,**作码率,英语:Bit rate,变量R)是单位时间内传输送或处理的比特的数量。比特率经常在电信领域用作连接速度、传输速度、信息传输速率和数字带宽容量的同义词。 在数字多媒体领域,比特率是单位时间播放连续的媒体如压缩后的音频或视频的比特数量。在这个意义上讲,它相当于术语数字带宽消耗量,或吞吐量。 比特率规定使用「比特每秒」(bit/s或bps)为单位,经常和国际单位制词头关联在一起,如「千」(kbit/s或kbps),「兆」(Mbit/s或Mbps),「吉」(Gbit/s或Gbps)和「太」(Tbit/s或Tbps)。

Bit rate 比特率(重定向自Data transfer rates)
In telecommunications and computing, bit rate (sometimes written bitrate or as a variable R) is the number of bits that are conveyed or processed per unit of time. The bit rate is quantified using the bits per second unit (symbol: "bit/s"), often in conjunction with an SI prefix such as "kilo" (1 kbit/s = 1000 bit/s), "mega" (1 Mbit/s = 1000 kbit/s), "giga" (1 Gbit/s = 1000 Mbit/s) or "tera" (1 Tbit/s = 1000 Gbit/s). The non-standard abbreviation "bps" is often used to replace the standard symbol "bit/s", so that, for example, "1 Mbps" is used to mean one million bits per second. |
