A receiver for recovering serial digital data, such as teletext, achieves an effective sampling rate which is a multiple of the local receiver clock frequency by passing the data signal through a multi-tap delay line. The delay line outputs are supplied to a register, and the register output which yields...http://www.google.fr/patents/US5140620?utm_source=gb-gplus-shareBrevet US5140620 - Method and apparatus for recovering data, such as teletext data encoded into television signals
