I have tried to find a description of it on the internet with Googal without success. In particular I was looking for a diagram showing the field blanking with the Bruck blanking sequence highlighted over 4 fields.<br /> <br /> 2&quot; quadruplex VTRs made by RCA, in particular the TR70B, used the Bruck blanking to set the timing of the edit pulse on the control track.<br /> <br /> If the Bruck blanking sequence was wrong then the timing of the edit pulse could be 2 fields delayed compared to a standard recording and the recording would playback out of sync with the studio or presentation SPG.</div>
