I'm a undergraduate now working on a ultrasound subject, I used the<br>
vtkvideosource to capture the video but it returned error message "can't<br>

My ultrasound machine is GE LOGIQ P5.It's said that this device is able to<br>
output a digital video data through svideo and BNC.<br>
What should I do?<br>
Look forward for any help! THX!<br></blockquote><div><br></div><div>S-Video is analog, not digital.
