Hi, I think that the color bars should help ... specially since we know what to expect. A capture of a soap or something makes a nice demonstration :-)
When Eric gave me the samples, he took the tuner output at 5.75 Mhz (center of the 6 Mhz band) and then quadrature sampled it. Therefore in the final samples, the video carrier was at -2.75 Mhz, Audio carrier at 1.75 Mhz. I think you get the picture. Please capture may be a sec of video using a test signal generator and a sec of video showing some program. The color bars that Krzysztof pointed should help. Otherwise anything you can generate; as long as I know what they should look like :-) Regards PMD On Tue, 29 Mar 2005 13:54:42 -0700 (MST), [EMAIL PROTECTED] <[EMAIL PROTECTED]> wrote: > Would it be helpful to capture NTSC color bars or other test signals? > > I have an USRP and TEK signal generator. > > Where is 0Hz IF when you capture video? > > > On Tue, 29 Mar 2005, Prateek Dayal wrote: > > > Hi, > > > > I am testing my NTSC color decoding algorithm currently.
