Data rate: The data rate, also known as transmission speed, indicates how much data is transmitted per time. This information is often given in MB per second. At a Blu-Ray-Disk the data rate is 36 MBit/s, for example. One DVD comes to 6 MBit/s, a normal audioCD to 1411 kbps. The maximum data rate allowed by HDMI supported is 10,2 Gbit/s.
