GHOST ERASING STANDARD SIGNAL PRODUCTION AND TRANSMITTER-RECEIVER DEVICE IN TV AND THE METHOD OF ERASING GHOST

摘要

The ghost cancelling reference (GCR) signal transmitting/receiving apparatus and ghost cancelling method in a television system comprises a GCR generating circuit for generating GCR signal having a first step, a superimposing circuit for superimposing the GCR signal to a vertical blanking interval of a television signal, a transmitting circuit for transmitting the television signal in which the GCR signal is superimposed, a receiving circuit for receiving the transmitted television signal, a GCR separating circuit for separating the GCR signal from the received television signal, a GCR processing circuit for generating a ghost cancelling control signal, and a ghost cancelling circuit for cancelling a ghost signal by the ghost cancelling control signal, thereby improving television picture quality.
