发明名称 Video signal recording apparatus.
摘要 <p>In video signal recording apparatus a video signal is processed (3, 5, 6, 10, 11), such as in time division multiplexed format. A burst clock signal (B) of frequency fb is generated (8) for recovering the video signal during a subsequent reproduction operation, and this burst clock signal (B) is added (40A, 40B) to a DC level portion (H) that is present in the processed video signal, resulting in a combined signal. The combined signal is frequency modulated (14A, 14B) and recorded ( 70 ) on a record medium ( 18 ). Assuming that the DC level (H) of the processed video signal is represented by a modulating frequency fa, and m is an integer, if: &lt;MATH&gt; &lt;MATH&gt; &lt;IMAGE&gt; &lt;IMAGE&gt;</p>
