GHOST CANCELLATION REFERENCE SIGNAL DETECTION AND SYNCHRONIZATION |
摘要 |
A circuit for detecting and synchronizing a ghost cancellation reference (GCR) signal in a television video signal, includes a circuit for receiving at least one field of an input video signal, a circuit for finding a maximum correlation peak value in a field of said input video signal, a circuit for scaling the maximum correlation peak value to a lower predetermined value for detection for forming a scaled peak value, a circuit for synchronizing a next field of the video signal using the scaled peak value, and a circuit for predicting a future position of the GCR signal.
