The number positions indicate the end of lines.
The Teletext composite synchronization signal (TCS), whether interlacing is present or not, comprise
three components.
a) the line-synchronization pulses (LSP).
b) the equalizationpulses (EP)
c) the frame-synchronization pulses (BP).
The timing reference is specifiedby the descending edge of the signal LSP, with a tolerance spread of
±
100ns.
