What does bps represent in describing information transmission?

bps means bits/second, which means bits/second, that is, how many bits are transmitted in one second. Bit is the smallest unit of computer data, and the data in it is either 0, 1, or 8 bits. It is a byte. The English letters we usually use occupy 1 byte, while 1 Chinese character occupies 2 bytes.

bps is the abbreviation of bits per second, which means bits per second, which means how many bits are transmitted in one second. Bits are the smallest unit of computer data, and the data in them is either 0 , either 1 or 8 bits are a byte. The English letters we usually use occupy 1 byte, while 1 Chinese character occupies 2 bytes (that is, one word).

Bit rate is also called "binary bit rate", commonly known as "code rate". Indicates the number of bits transmitted per unit time. Used to measure the transmission speed of digital information, often written as bit/sec. According to the number of bits occupied by each frame of image storage and the transmission bit rate, the speed of digital image information transmission can be calculated.

Extended information

Most bitrate control schemes consist of two parts. One part is that the encoded bit stream output by the encoder is input into a buffer. For a constant bit rate channel, the data in this buffer is taken out at a constant rate. If the buffer is large enough, bit rate changes caused by MPEG image types, etc. can be smoothed out. This is required both for constant bitrate transmission and for variable bitrate transmission in general.

Bitrate is often used to measure the quality of sound and video files. For example, in audio files: 8kb/s call quality, 32kb/s medium wave broadcast quality, 96kb/s FM broadcast quality, 128kb/s ordinary MP3 quality.
