Bit Rate
VP
This a unit of measurement used to assess the transfer of data per unit over time.

a) The rate at which the compressed bit stream is delivered from the storage medium to the input of a decoder. The digital equivalent of analog bandwidth. b) The speed at which bits are transmitted, usually expressed in bit\/s (sometimes abbreviated "bps"). video information, in a digitized image for example, is transferred, recorded, and reproduced through the production process at some bit rate appropriate to the nature and capabilities of the origination, the channel, and the receptor. c) The amount of data transported in a given amount of time, usually defined in Mbit\/s. Bit rate is one means used to define the amount of compression used on a video signal. The uncompressed D1 format has a bit rate of 270 Mbit\/s. MPEG-1 has a bit rate of 1.2 Mbit\/s.[1]

Measured as "bits per second," and used to express the rate at which data is transmitted or processed. The higher the bit rate, the more data that is processed and, typically, the higher the picture resolution.
