What is Bit Rate?

Bitrate is a measure of the throughput of bits (or kilobits, megabits, gigabits, terabits) per second, written as bit/s or bps, kbit/s or kbps, Mbit/s or Mbps, Gbit/s or Gbps, and Tbit/s or Tbps.

The bitrate of a stream is a primary consideration in streaming. Higher-quality streams (with better resolution and larger frame sizes) have a higher bitrate than lower-quality streams. However, client bandwidth may limit the bitrate at which streams can be played back smoothly.
