<P><FONT color=#3333ff><FONT color=#000000>Right now the laboratory system I'm talking about is hypothetical. The reason I need some type of digital video recording software that allows me to view the recorded video in both encoded and decoded forms is so I can experiment around with the data stream and see what is really out there. If I could grab a screen shot I would, right now I can't. </FONT></FONT></P>

<P><FONT color=#3333ff><FONT color=#000000>Right now I'm guessing because I have no way to analyze a digital video stream. Right now I'm trying to see if I can find the type of software I will need to perform the analysis. I really don't kow what is possible until some sort of signal analysis is performed. </FONT></FONT></P>

<P><FONT color=#000000>I asked my cable company if they could install a pop-up blocker on their cable box. They jumped all over me saying they had no control over the signal originating from the boardcaster.</FONT></P>

<P>All I really wanted to know was if MythTV can be modified to show a recorded show in both encoded and decoded form.</P>

The entire show is recorded, and then the predicted commercials <BR>are flagged, and automatically skipped by the software. The analyzer <BR>can never be 100% accurate, and with disk space being as cheap as it is, <BR>it's simply not worth the 30% (1-2GB/hr) you would save by doing this in <BR>real time and discarding what could be false positives.<BR>_______________________________________________<BR>mythtv-users mailing list<BR>mythtv-users@mythtv.org<BR>http://www.mythtv.org/mailman/listinfo/mythtv-users<BR></P></div></body></html>
