<p>PROBLEM TO BE SOLVED: To provide a digital television transmission system provided with a data pulse and transmission clock pulse recovery circuit that recovers a data pulse and a transmission clock pulse from a serial data pulse stream. SOLUTION: The recovery circuit is composed of a 1st circuit that receives a bi-phase mark serial pulse stream and provides 1st clock pulses to a leading edge of one of which a leading edge of each bi-phase mark serial pulse stream corresponds, a 2nd circuit that receives the bi-phase mark serial pulse stream and the 1st clock pulses and provides a non-serial data pulse stream having a leading edge corresponding to a leading edge of one pulse in the 1st clock pulses, and a 3rd circuit that receives the non-serial data pulse and the 1st clock pulse to convert the non-serial data pulse into a recovered NRZ data pulse.</p> |
