bits Bit rate
A value that indicates how many bits of information are processed or transmitted / received per unit of time.
Also called transfer fee. The amount of information in one second of audio data and video data is expressed in “bits per second” (bps: bits per second). It is usually used with “k (kilo)” to represent a thousand units or “M (mega)” to represent a million units because the number of digits is large and is expressed as “kbps” or “Mbps” (1kbps is 1000bps, 1 Mbps is 1 million bps). It is often used in the audiovisual (AV) genre, and in the case of audio and image data, the higher the value, the more accurate the information, and the better the sound quality and picture quality. The standard bit rate for MP3, one of the audio compression formats, is 128 kilobits per second (kbps), which compresses the amount of information in an uncompressed WAV file (approximately 1400 kbps) with CD sound quality. to about 1/10. you can see that you are doing it. The bit rate of the video is higher due to the large amount of information, and the high definition terrestrial digital transmission is about 18 megabits per second (Mbps) and the BS high definition digital transmission is about 24 Mbps. a unit that expresses the transfer rate, “bytes per second” (Bps or B / s), which is a reference value that expresses the number of bytes per second. Since 1 byte is 8 bits, Bps can be calculated by dividing bps by 8.

Bit rate
It is the speed of data communication, which is the amount of data that can be sent and received in a given period of time. The unit is “bps”, which is short for “bits per second”. It is also used to refer to the amount of data used to express one second of video or audio when compressing video or audio. The higher the amount of data (= lower the compression rate), the more faithful it will be to the original, but a high-speed communication line is required.
On the other hand, as the amount of data is reduced (= the compression rate is high), the image quality and sound quality deteriorate, but transmission is possible even in an environment where the communication speed is slow .

Explanation of the “bit rate” dictionary that understands TI terms
Processed per unit of time, or the transfer is a bit number. It is generally expressed as a number per second and uses bps as the unit. It is expressed as a physical quantity, such as the speed of communication on a computer network and the transfer speed in transferring data with a circuit within a computer or peripheral devices. It is also used as a unit to express the amount of information per second when compressing audio and video data, and if this compression method is used, the higher this value, the higher the sound quality and picture quality. ◇ Also called “bit rate”, “bit efficiency” and “bit rate”.
