发明名称	TELEVISION SIGNAL DIGITAL TRANSMISSION METHOD
摘要	<p>PURPOSE:To attain the digital transmission of a television signal at a minimum transmission speed by using the least significant bit of a digital data corresponding to a signal front porch, a horizontal synchronizing signal and a back porch as a frame synchronizing bit. CONSTITUTION:In a frame of the television signal digital transmission method, the least significant bit Y0 among digital data Y0-Y8 after A/D conversion is replaced into a frame synchronizing bit F. As the frame synchronizing bit, '1', '0' alternate pattern is used and the digital data after A/D conversion is not converted but sent as it is. When the frame is detected from the frame synchronizing bit at the reception side, whether or not the frame synchronizing bit is included is discriminated by the signal after D/A conversion. Through the constitution above, the digital transmission of the television signal is applied at minimum transmission speed.</p>
