[mythtv-users] Digital Signal decoder

[quecumber256 at comcast.net]

I would like to view an incoming or recorded digital video in raw digital form, so I can look for specific digital flags. 



For example: I'm sure you have seen those stupid pop-up ads that usually appear on the bottom left hand side of your TV when a TV program resumes. I consider this unnecessary noise and would like to filter it out. Therefore, I would like to be able to view the program in raw digital form so I can see if I can spot thoses flags and filter them out. 



Thanks, 

Quecumber256

MythTV is designed to record TV shows.  When faced with a digital 
stream, it will tell the tuner card to only give it those streams it is 
interested in.  Once recorded, you can open the file up in 'od' and scan 
through it to your hearts desire.  If you actually want the whole 
unfiltered multiplex straight out of the demod, I'm not certain if tuner 
cards are even set up to allow that, but your query would best be 
handled by LinuxTV, the project that actually writes and maintains the 
tuner drivers.
