Manchester Coding is a protocal used for digital communications via radio
waves usually. It is popular in commercial and military ciricles as well
as satcom circuits.

The definition of Manchester Code is:

A code in which (a) data and clock signals are combined to form a single
self-synchronizing data stream, (b) each encoded bit contains a transition
at the midpoint of a bit period, (c) the direction of transition determines
whether the bit is a "0" or a "1," and (d) the first half is the true bit
value and the second half is the complement of the true bit value.
