[Discuss-gnuradio] Interpolation Issues

[bditri]

Hi,

In the process of demodulating the video sigal from the tv signal we receive, we
have been interpolating from 8 MS/s by a factor of 2 to 16 MS/s.  However, just
demodulating the audio alone takes 97% of our computer's usage, and as soon as
we interpolate to 16 MS/s the usage peaks at 100% and we get usrp overload
errors.  Currently our computer's processor is 3.6 GHz.  I was wondering if
anyone else has come accross computer processing problems when demodulating the
video.

thanks
Brent
