Is it possible to acquire images from our tv card instead of cameras? i am trying to test the outputs of a dvbs (satellite receiver), by these steps 1] we will feed the tv card inputs (composite,s-video,TV ) by our receiver under test's output... 2] the receiver plays a constant stream for example (color bar) 2] we will acquire images from tv card 3] and compare these images with the correct files at the pc (jpeg files) i just wonder is it possible to realize such a project ? also we should select the tv cards inputs from labview , i mean switch between (composite,s-video,TV ) inputs. best regards no external hardware just tv card and labview 8.5
